  Do you have questions about solar panels? You’re not alone! Even though solar has been around for a long time, many people want to know more before they choose if going solar is the right for their property. Getting to know PV panels is smart, so we have put together some of the most commonly asked questions about home solar panels and answered them in one place. From knowing how solar power works to knowing what happens to solar panels in weather, you’ll be smarter than ever about turning the sun into green energy once you’re done with these FAQs. Let’s get started. How Do Solar Panels Work? The short answer is that solar panels (comprised of photovoltaic - PV - cells) absorb and turn sunlight into electricity. The longer answer is that the silicon in PV panels, which is doped with boron to increase its conductivity, knocks electrons free from the sunlight that hits the panels. This creates an electrical current. Your panels convert the sunlight into direct current (DC) energy. How do solar panels work? Read the full article. Since most appliances in your home use alternating current (AC) power,  your solar panels are connected to an inverter. The inverter changes the solar energy from DC to AC. From there, the energy is ready to be sent to your outlets and used in your home. How are Solar Panels Affected by Clouds and Rain? One of the biggest myths about solar power is that it won’t be effective when it’s cloudy. Homeowners who live in areas with a lot of sea fog, for instance, may be worried that getting solar power isn’t worth it. The reality is that solar panels can still capture sunlight even when it’s cloudy outside. In fact, panels can often produce up to 25% of their typical output even when clouds are present. When it’s raining, your solar panels may produce about 10% of their regular output. During weather events, your solar panels can draw upon their storage of saved energy so your home can stay off the grid until the sun comes out again. Read our article Does solar power work at night? Do Solar Panels Overheat? You want your solar panels in direct sunlight. But how much sun is too much sun? Some panels do operate with less efficiency in super hot temperatures. Solar panels are tested for efficiency at 77 degrees Fahrenheit, and they’re most efficient around that temperature. Panels will lose a certain amount of efficiency for every degree above 77 (this is called the temperature coefficient figure). If you’re living in the desert, you may want to select panels with a better temperature coefficient. Thin-film panels, which are started to gain steam, are also known to work quite efficiently in hot temperatures. It’s important to note that your panels will still work when they get hot, they may just take longer to generate the same amount of electricity as they do on cooler days. They will draw on stored energy to make up the difference. Learn how often you should care for your solar panels. How Many Solar Panels Does a Home Need? How many solar panels will you need to make the switch from grid power to self-sustaining solar power? There are a lot of factors that contribute to the answer, including the efficiency of the panels you choose and how much power you use every month. For a home that uses 5kW of power each month, you will require on average about 20 panels. You’ll need 300 square feet of roof space, ideally facing south. How many panels are needed to run a house? Read the full article. Can Solar Panels Be Recycled? If you’re entertaining the thought of going solar you probably care about the environment, and you’re asking yourself how you can recycle the panels when you’re done with them. The good news is that solar panels often last up to 30 years, so you won’t have to change them out often. If you inherit a home with outdated panels and want to upgrade them, however, the rules of recycling may be pertinent to you. The EU has a more organized system for recycling solar panels than the United States, but the US is started to get on board. Many of the components of solar panels, including glass and wiring, can easily be recycled. Groups like SEIA and some individual manufacturers are allowing customers to turn in old panels for repurposing or recycling. Learn how to decrease your carbon footprint. Are Solar Panels Expensive to Maintain? No, solar panels are not expensive to maintain. Regular cleanings represent the majority of your responsibility; depending on where you live and the type of panels you have, you may only need to clean the panels annually. It’s best to consult a professional when you need your panels cleaned and schedule the cleaning for a day that is partly cloudy whenever possible. Aside from cleaning, you won’t need to attend to your panels unless you notice something wrong. Many solar panels have a warranty of 25 years for parts and materials, so you can also count on free replacement components in many cases. Can Hail or Snow Damage My Solar Panels? Solar panels are specifically designed to withstand harsh weather conditions. In fact, they are tested to make sure they can survive through one-inch hail falling at a rate of 50 miles per hour. The National Renewable Energy Laboratory (NREL) was itself faced with a hail storm, and of the thousands of solar panels on the organization’s campus, only one was broken in the end. When it comes to snow, the main problem is that snow coverage impedes panel efficiency. Many homeowners can simply wait for the snow to melt because the angle at which the panels are installed encourages the melted snow to naturally run downward. You can also hire a professional to come and clear the snow. Read more about the durability of solar panels. How Much Money Will I Save with Solar? The amount of money you save with solar may vary, but if you buy efficient panels and live in Southern California you are apt to save up to $40,000 over the course of your time in your home. You can use Google’s helpful Project Sunroof to estimate how much money solar panels can save you. The tool uses your address and current electric bill to provide you with an estimate. We answer the question we know that you have: Do solar panels really save you money? Can I Take My Solar Panels When I Move? Technically your solar panels are your property and you could take them with you to a new property. But you may not want to consider it when you factor in the increase in your home’s value. In California, a solar panel system that generates about 5kW could improve the worth of a home by tens of thousands. You’re typically better off to leave your solar panels in place, sell your home, and install a different system at your new address. Read more: Does solar really increase the value of your home? What is Net Metering? Many city grids, including SDGE have a program in place to buy your excess energy. Most homes with solar will create more energy than they need, so you may as well be paid for it! Net metering is a system by which homeowners who generate solar energy and remain connected to the grid will send their extra energy to the grid. Your utility company will pay you for this electricity and use it to offset the load for your neighbors. Anything beyond your personal “net” use is used to power your community. Read our full article on net metering. Solar power has the potential to make your household energy independent, reduce your carbon footprint, and help your community. When we reduce our reliance on fossil fuels, we create new jobs and help protect the California landscape we all love so much. Solar energy is also helping local veterans get back to work after they complete their service. More of your questions are answered on our Frequently Asked Questions page.

Many people faced electricity blackouts in California due to dry, hot, and low-humidity winds as well as widespread wildfires. A dozen counties shut their power off since sparks were emerging from aging power lines. It was done to avoid and control quickly-growing fires. Though the power was restored for a day, the residents were warned to prepare for a minimum of 5-7 days outage. This was because of the weather conditions at the time, which could have enhanced the risk of wildfire. Now, we are seeing even more shutoffs in counties such as Los Angeles and Ventura due to the strong winds. This is just one scenario. Blackouts and outages are not planned at times. Even if they are, the residents still have to be prepared to face the abrupt power cut. What should be done? The immediate solution is to have a Battery Backup Power Storage in your residence/building. What is the power required to back-up a battery? For a full charge, battery backup for home use needs 160 Watts in an approximate. Is Battery Backup Power right for you? The California outages were done for safety. However, such a scenario and an unplanned power cut make battery backup power essential and useful to many residents such as people with Sleep Apnea & CPAP Machines. Need for a backup home power system [video width="760" height="692" mp4="https://www.sempersolaris.com/wp-content/uploads/2021/08/07-2021-SMP-Website-Blog-Images-760x340-35628-2.mp4" loop="true" autoplay="true"][/video] A home power backup is also referred to as energy storage equipment. A backup that can power up your home for emergency filled with sustainable energy is cost-efficient. Whenever a power outage is experienced, the backup equipment will switch to the power supply until the power is back. The battery charges while the power is available. Systems like Tesla Powerwall & Enphase Encharge Battery are very efficient, larger in capacity, cost-efficient, and storage efficient. For example, with Tesla Powerwall, you will not even notice a blackout as when the backup mode is powered, Powerwall will seamlessly switch to this backup mode and stay powered for  7+ continuous days* The factors for having a battery backup power are: Climatic conditions- Extreme weather conditions such as fires, ice, floods, lightning, and wind can impact the electric grid. Accumulation of ice or a lightning strike can damage the power lines. Trees- Trimmed trees do not impact the power lines. However, they do not potentially void all the issues. The branches can sway or fall over the power lines damaging them. Potentially high wind can make the tree stoop over the power lines. If the tree is not trimmed, then they create all the more. Accidents-Construction and Vehicle accidents can harm power poles. This results in the power lines to touch or break each other. Grid overload- The equipment gets overloaded with extreme temperatures. The system is impacted when you are using electrical heating or AC at the same time. Which battery backup is right for you? The answer to this question is relative. Some factors to look for the right backup are: Any battery backup power system being right depends totally on what you need, place, and circumstances are. A reliable backup should be able to provide power backup for major power devices. If your climate is not suitable, you live in a disaster-prone region, or where there are chances of more power cuts then, the battery system should be able to sustain that break time. They should be affordable to you for charging, maintenance, and installation. 3 primary features of a Battery backup power right for you The below three vital features are essential in a backup battery Reliable Battery-The battery backup run using solar energy should keep it charged and shield the device from power issues. The connected power devices like lights, fans, etc., should be compatible with the internal battery supply. How many hours it is able to give you power supply in the case of a power outage depends on the battery size and wattage. The other factors to be considered are battery age, efficiency, and room temperature. The backup should be capable of offering computer data backup and avoiding any kind of data loss. Automatic Voltage Regulation- The battery should be equipped to shield abnormally lower or higher voltages. No damage or malfunction of hardware should occur at these times. This will correct the fluctuations without getting the battery switched on at these times. It will set the percentage by detection to 10-15 percent of the required voltage to switch. Noise and Surge protection-In-built noise filtering and surge suppression from a transient voltage that can be disruptive and destructive EM or RF line noise is abled in the system. Solar Energy Backup Power  The backup power system of this type uses solar panels to store solar energy as power backup. Solar Energy systems are also referred to as a PV array. The energy accumulated through the solar panels is directed to storage within the battery system for home use when needed. Whenever there is a power outage, this storage energy acts as a power supply to operate as per the power specifications enabled. Top advantages of Solar power backup The leading pros of solar energy power backup batteries are that they are eco-friendly. They have no or minimal impact on the environment. This is sustainable energy to reliable provide a power backup to your home or workspace without any harm done. They are able to give you energy security.

  If you are a sleep apnea patient and use CPAP therapy, you should be ready for emergencies where there would have no regular power available. To meet such eventualities, you should invest in solar panels and battery storage. For the past few weeks, California is witnessing regular rotational blackouts. Even in the past, California has witnessed a serious power crisis between 2000-01. Sleep apnea patients who are taking CPAP therapy may find themselves completely helpless if caught in a blackout in the night time. This is very much a real possibility now as peak power demand in the city is outstripping supply. How Do Solar Panels Help People with Sleep Apnea Using CPAP Therapy? You can buy a high watt solar panel system for charging your CPAP battery.  You just need to spread the solar panels facing directly the sun and connect it to the CPAP battery. In about 8 to 10 hours, the solar panel would fully charge the battery. The solar panel is very easy to operate. All you need to do is spread it facing the sun. It will draw energy from the sun and charge your CPAP battery. Solar panels are able to draw energy from the sun even on cloudy days when the sun may not be seen prominently. Benefits If there is a power outage and you are not able to charge your battery, solar panels will charge your CPAP device and you can have a good night's sleep. You may also need the solar panel to charge your CPAP device during your outdoor adventure. Easy To Use Solar Panels? The solar panels capable of recharging your CPAP device are lightweight and powerful. They can charge your CPAP battery in 8 to 10 hours. The process to recharge the CPAP battery is very easy. You just need to connect the solar panels to your battery and let the panel sit facing the sun. Most solar panels are made using green technology and are carbon-footprint friendly so you will be helping the environment in the process. Solar Panels and Sleep Apnea Is there a link between solar power and sleep apnea? Yes, if you are suffering from obstructive sleep apnea (OSA) and use CPAP (Continuous positive airway pressure therapy), solar power can be a topic of interest for you. CPAP is a device that comes in the form of a mask that sleep apnea has to wear during his sleep. The mask has a CPAP component that supplies air at high pressure near the patient's nose during his sleep. This ensures there is enough air at high pressure in the face region including the nose and the throat that the patient does not have to struggle to breathe the air in. There is a continuous supply of air at high pressure for the patient to be able to breathe comfortably. How Is CPAP Related to Solar Power? CPAP is powered by a rechargeable battery. For this device to continuously work for the entire duration when the patient is sleeping, it needs its battery with adequate charging. In normal circumstances, the battery can be charged through power outlets in the day for use at night. You may need solar power to charge the CPAP battery. This is a possibility when there is a power outage or when you are on a hike and sleeping outdoors. What is Sleep Apnea? Obstructive sleep apnea (OSA) is a serious problem that prevents a person from having a sound sleep. The problem is caused due to the weakening of the breathing muscles that mostly lie in the throat region. If the person is suffering from this problem for a long time, the lack of a good night's sleep can lead to many problems, especially related to the health of the heart. While a milder version of OSA can be treated and managed by adopting a healthy lifestyle, the more serious form of the condition needs medical interventions. Of all the treatments available, CPAP is considered to be most effective as it improves air circulation right in the face, near the nose, and the throat. It helps the patient's breathing system as air at a higher pressure makes its way through the nose and the mouth down to the throat and lungs without breathing muscles having to make any serious effort. CPAP manages to keep the patient breathing. It's a delicate balance between the patient's need for air and the CPAP working on its battery. If the battery gets discharged with no option to recharge it, the patient may suffer a difficult time trying to sleep. But if the patient has battery storage, he can recharge his CPAP device easily and manage to tide over the crisis. Solar Panels and Battery Storage Solar power is a source of clean energy as it provides non-grid energy. From average homes to municipal bodies, everyone is aware of the advantages of solar panel installations. They are also using it wherever it is possible. Except for the installation cost, it provides you electricity at much lower costs compared to no solar panels. Over time, it pays for itself and recoups the installation cost in about 5 to 7 years. There are good reasons for the greater adoption of solar power technology by more people and households. An important upgrade in the overall solar power technology is battery storage. This device allows you to store power generated by your solar energy system and use it when you need it. In normal circumstances, your solar panels generate electricity and store in the batteries attached to the system. Once the batteries are fully charged and your solar panel is still producing electricity, you can store the additional electricity in battery storage. You can use the battery storage when the normal batteries attached to your solar panels are completely discharged. You can also sell additional electricity to the grid and earn some money or credit. Using battery storage is an excellent way to tap the maximum amount of energy from your solar installation. Final thoughts Sleep apnea is a respiratory disease in which the person stops breathing for a brief period during his sleep. One of the treatments for this condition is the use of CPAP masks. To keep the CPAP working even during California blackouts or during outdoor hiking, you should use solar panels + battery storage in case of emergencies.

  Are you aware that scientists have spent thousands of years trying to understand the promising solar energy and its application? Yes, understanding the 'how' of harnessing the Sun's power and meaningful use has been an uphill task that has ignited various scientists' interest in developing a concrete solution. Below is a timeline of multiple achievements and milestones covering various human efforts to extract and use solar energy. How is solar energy extracted from sun rays? Through the use of Photovoltaic devices. These are a particular type of metal that, when exposed to sunlight, use the photovoltaic effect to produce electricity. It is estimated that the knowledge about this photovoltaic effect has existed for roughly two centuries, and for this reason, our history about the solar cells begins here. How was solar energy initially used? Theoretically, it is believed that humans began to use solar energy by 7th century B.C. History reviews that humans were using sunlight to ignite the fire using magnifying glass materials. 700 BC- The use of a magnifying lens to put on Sunlit Fires' Heat Ray'. Do you know by the 7th century B.C humans could make fire using a magnifying glass to concentrate sunlight? For instance, around. 214-212 B.C. historians hypnotize that Archimedes' a great Greek inventor, was able to apply solar energy by creating heat rays using multiple mirrors to concentrate sunlight. It is believed that he destroyed several ships by concentrating sunlight on those ships belonging to Greek enemies especially during the Siege of Syracuse. Although this Archimedes' invention's validity is not apparent, various experiments have shown that it could be possible but more unlikely to have been executed. Romans are also known to use mirrors to harness the solar power and using it as light torches during their religious ceremonies. The use of "burning mirrors" became prevalent among Roman, Greeks, and later to the Chinese civilization. When was the first invention of the solar panels? 1767- The invention of the first solar oven A solar oven, often known as the solar cooker, uses the heat created by concentrating sunlight to heat drinks or food. Solar cookers are in use to date and are cheaper and efficient compared to the previous models. They are the most popular heating solutions, especially world parts, with limited access to electricity. The device relies only on sunlight to function, and this means no fuel or electrical power is need for it to work. The first solar oven was invented in 1767 by Horace De Saussure, a renowned Swiss Physicist. By the time of invention, nobody could have thought that this invention could be among the most helpful innovations for the next two centuries by helping people prepare their lunch and dinner without using firewood. 1839 - The Photovoltaic Effect Discovery by Edmund Becquerel. One of the most critical years in the history of solar panels was 1839 when Edmund Becquerel, a 19-year-old French physicist, discovered that there is a voltage difference when specific material is exposed to sunlight created. With his little knowledge about the photovoltaic effect, Edmund Becquerel dint understands that his discovery would form the basis of solar power in use in modern today. In 1873, Willoughby Smith, a staunch English engineer, coined Photoconductivity in Selenium, especially in its solid-state, which was another significant discovery that led to a great milestone in the solar energy industry. 1876 - Invention of Electricity from Light. While advancing the Smiths discovery three years earlier, an English professor, together with his best student, Richard Evans Day, observed a flow of electrical current when specific material was exposed to sunlight. Two electrodes attached to a selenium plate were used to make the tiny electrical current after exposing those plates to the light. 1883 - the making of the first Design of a functional Photovoltaic Cell. The credit goes to Charles Fritts, an American inventor who was the first person to design a successive solar cell plan. His 19th-century simple Photovoltaic Cell design was based on selenium wafers. 1905- The Photoelectric Effect and Albert Einstein work. Although most people aren't aware of Albert Einstein's photoelectrical effect paperwork, he is famous for his outstanding scientific milestone in the human race. He is the first person to formulate the photon theory of light, an idea that explains how light can dislodge 'remove or liberate' an electron from a metal surface. Sixteen years later, in 1921, after submitting his photon theory of light paper, he received the Nobel Prize to discover a tremendous scientific breakthrough.  1918 - The discovery of a Single-Crystal Silicon. The credit goes to a Polish scientist, Jan Czochralski, for figuring out a technique in which to grow single-crystal silicon. His discovery lay the foundation for the creation of solar cells using silicon metal. 1954 - The actual invention of Photovoltaic The credit goes to three scientists, namely, Gerald Pearson, a member of Bell Labs, David Chapin, and Calvin Fuller. Their work led to the creation of the world's first solar cell (photovoltaic cell). In simple terms, these men came up with a device that could convert sunlight into electricity. Many maintain that their silicon photovoltaic (PV) cell invention symbolizes the real PV technology invention. The first device could consistently power a considerable electrical device for more than two hours a day. However, the first silicon photovoltaic cell could only operate at 4% efficiency, below a quarter of modern solar cells capacity. They later advanced its performance (conversions efficiently), increasing it from 4% to 11%. Today, these solar panels are so advanced that they are used to light big houses and run machines due to their improved efficiency. Other significant achievements in the history of solar panels. The use of solar panels to power outer space devices. The use of solar technology in outer space is one of the most recent solar energy industry achievements. The outer space solar panels were used to run satellites. A good example is solar panels power Explorer III, Vanguard II, and Sputnik-3 satellites in 1958. Others include creating the first solar residence in 1973 by a team of scientists at the University of Delaware, Improving solar conversion efficiency from 8% to 14% by Hoffman Electronics amid 1957 and 1960. By 2016, the conversion efficiency had reached 34.5% efficiency and innovation from The University of South Wales.

Owning a house that runs entirely on solar power is most definitely a possibility! With the help of solar panels and solar batteries, making your home a solar-powered property has never been cheaper. The cost of installing a solar energy system has dropped drastically in the past 20 years because of the fast improvements in technology. Even though it may be cheaper than ever, there are still a few necessities to make this dream of running your home on solar power alone, a reality. First, you will need to understand how much energy you use on average per month. This will allow you and your contractor to know how much energy your panels may need to generate to keep your home powered throughout the month. When considering the amount of energy generated by your panels, it is also smart to understand that some months may be better than others for generating power. This is where solar batteries can play a crucial role. When the sun doesn’t shine as bright or as long as usual, it is good to utilize your solar batteries. Solar batteries allow users to store excess energy gained on those long sunny days to be used later. This is key because if you have no energy stored, you will be required to use energy from the grid to power your home. Secondly, the climate you reside in also plays a crucial role in making this dream a reality. If you live in a cold, cloudy place, it may be more challenging to run your home entirely on solar. For example, while living in the Pacific Northwest during the winter months, you may go weeks without seeing direct sunlight. Although, if you live in the southwestern states like California or Arizona, you may go weeks without having an overcast day! These differences in climate play a critical factor in the ability to jump on the solar bandwagon and cut ties with the energy company. Third, the surrounding trees and houses located near your home. These can hinder the amount of energy that your solar panels can generate throughout the day. If you have a huge tree blocking your panels for a third of the day, this can drastically change the amount of energy stored. Make it Possible Don’t let any of these three factors scare you away because running your home on solar alone has never been easier. With the help of solar estimators and countless numbers of installations in your general area, solar contractors understand the ins and outs of what may be needed to allow you to make this leap to solar energy. The key to this possibility is the number of panels and solar batteries installed on your home. The critical part is the use of solar batteries; without a battery, no excess energy can be stored to use later. Semper Solaris is a Tesla Powerwall certified installer, and with powerful batteries such as Tesla Powerwall out on the market, this possibility is closer than you think.

If you are thinking about going solar at home, but you are having doubts about the payoff, Google can help you make an informed decision. Combining the abundance of their satellite imagery and sophisticated algorithms, Google is now offering a new service that will provide you immediate insight into what you could expect in terms of savings with rooftop solar. This August the company rolled out Project Sunroof, a service that “maps the planet’s solar potential” by analyzing the high-resolution aerial photos of Google Earth. A three-dimensional model of your home is created and then the artificial intelligence software evaluates how much sun exposure the panels would have and how much savings that investment would make you. Joel Conkling of Google says that people constantly use Google to explore solar, but allowing them to test how much they would gain by going solar is so much more helpful. For now, the availability of service is limited to the Bay Area in San Francisco, central Cali and greater Boston. It was developed by Carl Elkin, a rooftop solar owner who lives in Cambridge and works for Google. The project was developed during his “20 percent time” – that time allowance Google gives their employees to work on their own independent projects. How does Google examine your roof? Elkin has installed solar panels on the roof of his home in Massachusetts. He says his drive was for people to understand that going solar is a very good home investment. Google and the project author consider this web application will promote solar panels and encourage more people to make the green change. They add that the timing for the service release is just right, with the incentives and the cost of installing solar being lower than ever. Google’s algorithms are very intricate and they emulate the neuron web in the human brain to separate your roof from the trees and shadows nearby. The technology is actually the same like the one used for face recognition on Facebook and instant translation on Skype. Project Sunroof includes simulation of shadows that normally shade your roof and it also takes into account the weather patterns in the area. Another variable that factors in is the typical local utility rates or you can enter the amount of your monthly utility bills for an even more accurate estimate. This project isn’t just Elkin’s brainchild or his personal crusade. It’s a natural development that fits into Google’s long-known support of solar and renewables. Their data centers are already solar-powered and they have invested in home solar projects. However, we shouldn’t expect this is mere beneficence. Google is all about marketing – the service will soon include referrals to solar companies in your area and charge those providers fees for doing so. Conkling explains that they want to bring people closer to understanding the potential of solar electricity, but they can also make some money off of that.

What is Tesla Powerwall?

Tesla is a leading American company famous for manufacturing electric vehicles. The company is moving forward to bring innovations in other industries. Tesla Powerwall is a step towards this direction. This innovative technology can help to store energy for residential and commercial usages. Tesla Powerwall is a lithium-ion battery that you can use as an alternative to power your home. You can use this as a backup to support your energy needs. This is a wall or floor-mounted battery system designed to store energy generated by wind turbines, solar power panels or the grid (electric company). You can use Powerwall daily to power your home. Each battery can store up to 13.5 kWh of energy, weighs 251.3 pounds, and offers an easy installation. You can install it both inside and outside of your home. However, the installation needs to be done by a certified technician. Semper Solaris is a proud Tesla Powerwall certified installer. How to Use Tesla Powerwall There are three ways to use Powerwall. You can get a complete power source to meet the energy needs of your home. Its off-grid approach will enable users to power their homes fully by using the solar battery storage. You can install one or two Powerwall batteries depending on your requirements. Powerwall can be considered as a supplementary power source for your home during the evening or when you need it most. Powerwall can be ideal for the backup power supply in case of a power outage or blackout. Once installed, it can be accessed through the intuitive, easy to use dashboard. The dashboard gives you control of power being used in your home and allows you to adjust the time and settings of your Powerwall. How Does A Tesla Powerwall Work? Each part of the Powerwall system will be plugged into the electrical panel of your home. The Powerwall will collect and store energy. You will need a setup with a few components, and it will be installed in your house. Powerwall Battery Pack This is one of the crucial components of a system. This pack will merge with your electrical panel to enable you to use the solar storage for emergency or daily use. Solar Panels Solar panels are the best option to convert solar energy into electricity. The solar panel will store solar energy during the day hours to be used at night when solar panels are not receiving sunlight. Inverter The inverter is what will convert solar energy into electricity. With the Tesla Powerwall, the inverter is built into the battery. Backup For the backup usage, you will need to download the Tesla mobile app to view and set up backup for your Powerwall. According to Tesla, “Powerwall is now designed for whole home backup. With whole home backup, your Powerwall system can support your entire home with backup power during an outage.” Tesla Powerwall is supported by ten years warranty. It is designed to offer a worry-free approach to meet the energy needs of your home or office. Charging Your Powerwall Tesla Powerwall is a great way to store any unused energy for future use or emergencies. To use your Powerwall, in any situation, you must charge it. Powerwall and the Grid According to PG&E, battery storage has two main functions, to charge and discharge. Charging can be done through your solar system or through the grid, or the electric company. Discharging is using the stored energy from your battery storage or returning it to the grid. Tesla Powerwall can be installed in your home with or without solar. When Powerwall is installed with solar, it will not be able to be charged from the grid, as it will be charged from the solar panels on your home. When Powerwall is installed without solar, it can be charged from the grid, or electric company, if it is in Backup-Only or Time-Based Control. Backup Only According to Tesla, "Backup power mode or Backup-Only reserves 100 percent of your Powerwall energy to provide seamless power to your home in the event of an outage. Powerwall will charge from the grid or from your solar system, and only discharge during a grid outage." Advanced Time-Based Control Time-Based Control helps you maximize savings by smartly charging or discharging your Powerwall" according to Tesla.

Have you ever been without power in your home when you really needed it? Have you ever had to fumble around your house with a flashlight between your teeth, or to light every candle you own? Or have you ever been without power for so long that you hesitated to open the fridge, not wanting to let any precious cold air out? For those of you that have experienced a power outage, especially a long one, you know exactly how unpleasant it is. Yet, in 2019, power outages will be the price that many Californians will pay in order to help avoid disastrous wildfires. California electric companies have started taking more proactive measures in order to prevent wildfires, like the deadly Camp Fire that killed 85 people in 2018. According to Time, California’s wildfires have only gotten more frequent and more costly in the last few years. Through research and debates, electric companies have discovered that fallen power lines or other electric accidents can be major contributors to these terrible fires. With that in mind, they have decided to implement outages when fire danger is especially high. Californians should expect to see these power outages this summer. When winds are high and humidity is low, electric companies like PG&E are planning to shut off all power to at-risk areas until the danger is lower. PG&E will also specifically be implementing other fire-safety changes like clearing brush and conducting more regular inspections. So what does that mean for the average Californian? In short: more rolling blackouts. Whether you’re under PG&E, Southern California Edison, or Sempra Energy, you can expect your power to be shut off--sometimes for days at a time. This raises an important question: what can you do about it? Of course, there are all kinds of ways to prepare for a blackout. You could stock up on flashlights and candles, or have battery-powered lights easily accessible. You could also keep insulated bags on hand for your freezer food. Remember to keep extra ice packs for your other food in your fridge--and some for yourself, because no power in the hot California summer also means no air conditioning! Finally, whether you’re expecting a blackout or not, it’s always a good idea to keep extra containers of drinkable water on hand. Will My Solar Panels Work in a Blackout? Yes—Through Battery Storage! However, there’s another, much easier way of dealing with an energy shut-off: having your own power supply. When other Californians may be sitting around candlelight, still sweating in the summer nights, you have another option. Californians all over the state are installing solar panels for all kinds of reasons, including saving money on electric bills, “going green,” and increasing home value. One of the most beneficial reasons to install solar panels, however, is having your own power supply when the grid’s power is cut. Solar panel systems can now be installed with battery storage, which means long-lasting energy stored for extra energy or for emergencies such as a power outage. These batteries are connected to your solar energy system and store any extra energy that your system produces. Not only are they great for emergency power shut-offs, but they can also strategically sell back some of that extra energy to the grid during peak hours. This means that your system can save extra energy and money, no matter what your energy circumstances! Semper Solaris Offers the Tesla Powerwall There are several energy storage systems available, though two of the most popular are the Tesla Powerwall and Enphase Encharge Battery. Semper Solaris is proud to carry both. In fact, though over half of solar energy installers report that consumers are asking for Tesla’s Powerwall above any other system, only 12% of installers actually have the Powerwall available. The manufacturer of the Powerwall, Tesla, is constantly growing in consumers’ minds, likely due to exciting news coverage and technological developments. For example, in the fall of 2018, Elon Musk’s space car passed by Mars, meaning that it had traveled many more miles than any other car on the face of the Earth. It’s no wonder that Americans are asking for anything Tesla develops, and many solar installers are simply not equipped to fill the growing demand. Semper Solaris is a Tesla Powerwall certified installer and proud to partner with companies like Tesla in order to provide exactly what customers want and need, including battery storage. Though battery storage has always been an excellent addition to any solar power system, it will become essential during this summer’s rolling blackouts. No one should suffer from being unable to sleep in hot summer nights. No one should have to deal with perfectly good food going bad due to a turned-off fridge. And no one should have to sit around in the dark with their family and friends in their own home! In the end, these rolling blackouts are a cost that many are willing to accept if it means that lives can be saved. No one wants to see more horrible wildfires or any more homes burned to the ground. Many are praising California’s electric companies for doing whatever they can in order to help. However, this doesn’t mean that dealing with the blackouts will be easy! Though no one wants to endure a blackout, the response from consumers doesn’t need to be frustration and anger. Instead, consumers can respond by taking the necessary steps to make sure they’re prepared for what’s coming. By gathering their own energy from solar panels and storing it, people all over California can do their part to help prevent wildfires without sitting in the dark. Contact Semper Solaris today to install your solar energy system, including battery storage, before the summer fire season hits. While your neighbors may be enduring spoiled food and dark rooms, your family will be comfortable and enjoying your lights and air conditioning. In fact, after installing your new battery storage, consider inviting your neighbors over so they don’t have to suffer, either!
