top rated solar panels | Solar Panels, Battery Storage, Roofing, HVAC
Have you made the decision to go solar? Now is the perfect time to take advantage of all the beautiful California sunshine that lands on your roof each day by investing in solar panels for your home. As you begin researching which solar panels to buy, you might be surprised to discover dozens of solar panel brands currently on the market. So how can you find out which top rated solar panels are the best fit for your energy needs, your roof and especially your budget? It’s simple: when you sit down with an expert during your solar consultation, ask these five important questions: What Are the Price of the Panels? For most homeowners, price is one of the most important factors in their solar panel purchase decision. If you plan on paying out of pocket, then solar panels represent a steep investment. Although cheaper solar panel options do exist, at some point you begin to sacrifice performance, efficiency, and design in exchange for a little bit of savings upfront. In our opinion, this trade-off isn’t worth it! How Efficient are the Panels? Before you buy a new car, most people want to know about engine type, if it has four-wheel drive, and if it will parallel park for you so you never ding the curb again. We all want to know the specs of the things we buy. Solar panels are no different. One of the most important specs to look for, in this case, is efficiency. Efficiency refers to how much sunlight (also called solar irradiation) the panels convert into electricity. These days, new advances in monocrystalline and polycrystalline have dramatically boosted the efficiency of solar panels. Unsurprisingly, the cheapest panels on the market will give you the lowest efficiency rate, around 10%. (Fun fact: The first commercial solar panel only offered a paltry 2% efficiency rate!). With mid-range solar panels, you can expect 14 – 15% efficiency. Top rated solar panels can reach past 20% efficiency in ideal conditions. Why is efficiency important? More efficient solar panels need less surface area to create the same amount of energy as a less efficient panel. The most efficient solar panels can be smaller, which can be useful if you have a small roof or if there is a limited area of your roof that receives ideal sunlight. If you have a larger roof, you may want to consider purchasing less-efficient panels. They’ll be bigger, but you could save a little money! What Is the Warranty? Almost all solar panel manufacturers offer some form warranty that guarantees that their solar panels will continue to perform at a certain level for a specific stretch of time. It’s important to recognize, though, that warranty is not the same thing as lifespan. The top warranties are typically 25 years, but many researchers believe solar panels can last much longer without losing too much efficiency. Still, warranties matter. If they start to malfunction, that warranty can protect you from expensive repairs or from a loss of efficiency that could increase your monthly energy bills. What Is the Temperature Coefficient? We’re digging a little into the weeds here, but knowing the temperature coefficient of your solar panel options will help you make the best choice possible. It will also impress your solar panel installation company! Simply put, the temperature coefficient will tell you how your solar panels will perform outside of ideal conditions. Solar panels work best at 77 degrees Fahrenheit. Here in San Diego, Riverside, and Los Angeles, temperatures can blaze high above that in the summer, which will lower how much electricity your solar panels will produce. A solar panel’s temperature coefficient will tell you exactly how hot temperatures will affect efficiency. For every degree above 77 degrees, the efficiency of the solar panels will decrease by the temperature coefficient. What Is the Reputation of the Brand? Ultimately, the success of your solar investment will come down to how well your solar panels perform, and that will depend significantly on the quality of their construction. The top rated solar panels offer the highest efficiency, the best warranties, and the lowest coefficients, because they are designed by innovative companies that care about creating a quality product. You will pay more for these panels in the short term, but they will no doubt pay you back and then some over the long term!

When you make an investment in solar power, the dream is to save thousands of dollars each year on utility costs and perhaps even sell some of your excess energy back to the grid. With the proper installation and maintenance, a set of solar panels can last decades and be a sound financial decision. In fact, solar panels have been exceeding expectations when it comes to average lifespan. PV panels built after 2000 can produce up to 92% of their original power at the 20-year mark. Even with so much good news around the improvement of solar panels, it’s still wise to choose PV panels that are known for efficiency and a good temperature coefficient. Simply put: Solar panels are improving across the board, but they’re still not created equally. The top rated solar panels in the US (all available for installation in California) check all the right boxes. The first step to choosing one of the best ranked solar panels is understanding what you’re looking for and why things like efficiency quotients matter. Understanding What Makes the Top Rated Solar Panels So Good When does a solar panel go from OK to better than the rest? The top-selling solar panels typically earn great customer reviews, are efficient, and have an impressive temperature coefficient range. The first standard is pretty self-explanatory: but what exactly are efficiency and temperature coefficient ratings? Efficiency refers to the amount of sunlight that the panels can convert into electricity. The more sunlight your solar can convert, the fewer panels you’ll need to buy to successfully power your home. Temperature coefficient relates to how the PV panels react to a temperature increase. In Southern California, this rating is especially important. If you’re living in the desert, the last thing you want is a panel that loses its efficiency during the summer -- just when you need it most. Most solar panels are tested at 77 degrees Fahrenheit. The temperature coefficient figure tells you how much efficiency the panels lose for every 1 degree of temperature increase. For instance, a panel with a temperature coefficient of -0.3 will lose 0.3% of its efficiency for every temperature degree above 77. With these three components in mind, let’s take a look at some of the most highly rated solar panels for use under the California sun. These are the American-made panels that Semper Solaris has come to trust as experts in the business. Panasonic Panasonic panels have an efficiency range of 19 to 21.6% and a temperature coefficient of 0.258. The company uses 20 internal tests during their quality assurance process and offers an impressive 25-year warranty for the materials. The projected output is nearly 91% after 20 years, so the panels are a good long-term investment for your property. When it comes to customer feedback, Panasonic PV panels earned a 5-star consumer rating on SolarReviews as of late 2018. At Semper Solaris, we love Panasonic because they are truly committed to making the world a cleaner place to live. Not only are their solar panels so energy efficient that they’re at the top of their game, but even the packaging for Panasonic solar panels is eco-friendly. They minimize the cardboard waste associated with your PV panel installation, so you can feel even better about using this brand for your solar panels. Finally, Panasonic is considered one of the top rated solar panels by Semper Solaris because teaming up with the company has allowed us to offer you one of the only 100% American made solar panels available in California. Panasonic solar panels are manufactured in Buffalo, New York. Other companies might boast American assembled or American made panels, but some of the manufacturing could be outsourced. We love that Panasonic is committed to building the solar industry in the United States -- and doing it with quality panels that we’re proud to install for you. Silfab Silfab is another North American company that brings you a quality solar panel. The efficiency range for Silfab PV panels is 15.3 to 19% and the temperature coefficient ranges from 0.38 to 0.42. If you go with Silfab solar panels from Semper Solaris, you’re covered by a 25-year product warranty. Their residential solar solutions aim to combine esthetic architecture and maximum power density for projects of all sizes. Their all-black panels are particularly sleek if you want to install dark panels that blend into asphalt roof tiles. Silfab has facilities in Toronto, Canada and Bellingham, Washington. Their North American production lines are certified to deliver Buy American products, and they use precise engineering. Silfab boasts the lowest defect rate in the US. If you’re looking for a great domestically made solar panel for your home, ask us about our Silfab panel options. Why American Made is Important to Semper Solaris You’ll probably notice that the two top brands we install in California both have roots in American production. We think creating an America that is rich in clean energy starts from the ground up. It’s not enough that we install solar panels to leverage the sun into electricity for our homes; we should also add to the American economy by creating jobs right here! Solar has and continues to be a major job creator in states that have adopted a solar state of mind. California ranks first in the nation for solar installations and we also have more than 86,000 jobs in solar! The solar industry is a particularly great source of employment for veterans. The Department of Energy has created initiatives to take the technical skills of military veterans and put them to great use in clean energy. By supporting American-made solar panels, you’re helping your local economy and putting people to work. Using American manufacturing for solar panels not only helps the economy and creates jobs, but it also makes it easier to protect our environment. California is rich in incredible landscapes, from the beach and mountains to the deserts and farmland. We can better protect our precious terrain from harmful carbon footprints by promoting more regional solar panel creation. Making panels at home often means they’re more affordable and can be delivered quickly, allowing installers to get jobs done fast. The Bottom Line When Choosing Solar Panels There is an ever-growing list of companies who are getting into the green energy game. From Mitsubishi to Hyundai, some household names you probably recognize from other industries are now on board with using their technology and manufacturing to create sustainable energy. There are also many smaller companies who are committed to creating efficient solar panels. In other words: you will always have a lot of choices when it comes to where to buy solar panels and storage. Deciding which solar panels are right for your home depends on a lot of factors. Affordability is often at the top of any priority list, but efficiency and temperature coefficients should be close behind. Getting quality PV panels installed means less maintenance and better home value. A more efficient solar panel will also fare better in cloud cover or extreme heat, so you’ll thank yourself later for investing now. Panasonic and Silfab products are two of the top-rated panels for a reason. Not only are they sourced from North America, but they are quality products with long warranties. But you don’t have to memorize their differences -- we are here to walk you through choosing the right solar system for your property.

A solar panel system for your home is no small purchase, so how can you make sure to protect such a big investment? The good news is that top-rated solar panels are designed to withstand heavy winds, punishing rainstorms, mounds of snow, sizzling summers, and freezing winters. In other words, solar panels are pretty durable! The vast majority of solar panel systems can operate for decades without a problem, but that doesn’t help if you happen to be in the small minority of customer to receive a faulty panel. That is why solar panel warranties should be an important factor in your solar purchase decision. What types of warranties do solar panel manufacturers offer, and how can you effectively evaluate different types of solar warranties? Why a Solar Panel Warranty Matters It isn’t exaggerating to say that a solar panel system is a multi-decade investment. But although it might seem like a lot of money, solar panels offer savings in the long run by dramatically lowering or eliminating your monthly electric bill. (They also increase the value of your home!) The tradeoff of an upfront investment in exchange for net savings over time depends upon a solar system that functions as promised. If your panels fail, or if their efficiency quickly diminishes over the years, then you’ll never get the savings you expected. A solar panel warranty is a guarantee that your solar system will operate as advertised so that you can enjoy the savings you were promised. Too often, when customers compare different solar panel models, they only look at upfront factor: the efficiency of the panels and the price tag. It’s easy to overlook the value of a warranty because it only comes into play when something goes wrong. Don’t make this mistake. A warranty is a valuable feature of a solar panel brand and should definitely factor into your solar panel purchase decision. The Different Types of Solar Panel Warranties When you start shopping for solar panels, you’ll discover that top-rated solar panels offer more than one type of warranty. The two more common types of warranties are the product warranty, which covers all the parts of the solar panel and the performance warranty, which guarantees a certain level of performance over time. Additionally, you may be able to snag warranties on other related parts, including a warranty on your system’s inverter and on a solar battery. Let’s look at each of these warranties in more detail. What Is a Solar Panel Product Warranty? Solar panels are designed to take a lot of punishment from the environment, but sometimes even they fail. A product warranty (also called a materials warranty), covers the integrity of each of your solar panels. Product problems can occur as a result of: Manufacturing defects (such as faulty wiring) Corrosion Other types of premature wear Environmental issues Many solar panel manufacturers offer 10-year product warranties. Top solar panel companies like Panasonic offer a 25-year product warranty. Consider the added value that longer warranties offer. A typical solar panel would cost you a small amount to replace out-of-pocket. A 25-year warranty protects your solar investment for 15 years longer than a more standard 10-year warranty. In fact, a 25-year warranty will essentially guarantee the integrity of your panels for the life of your roof. Keep in mind that a 25-year product warranty also signals that a company has extremely high confidence in the quality of their product. How to Use the Warranty If you notice that a solar panel or multiple solar panels aren’t working, your first step should be to contact your solar installation company. If they determine that a solar panel is faulty, then it’s time to reach out to the manufacturer. If all goes smoothly, the manufacturer will ship a new panel or panels to you. Ideally, they will also cover shipping and installation costs. What Is a Solar Panel Performance Warranty? As with almost all technological products, solar panel performance degrades over time. Each year, a typical solar panel loses about 0.7% of its efficiency. This means that, over time, your solar panel system won’t be able to produce as much electricity as it did in its first years. (Youth is so fleeting!) Solar panels lose efficiency at a relatively reliable rate, which means that manufacturers are able to anticipate the rate of loss and offer a performance warranty to protect against extreme degradation. Performance warranties guarantee a certain level of performance over a certain amount of time. For example, a typical performance warranty will guarantee 90% of production for 10 years and 80% production for 25 years. When evaluating a performance warranty, it’s important to also understand the efficiency rate of different solar panel brands. For example, even though Panasonic and KYOCERA solar panels both offer an 80% production warranty over 25 years, Panasonic’s maximum efficiency rate is 21.6%, while KYOCERA’s max efficiency rate is only 16.1%. How to Use the Warranty It can be tricky to tell if your solar panels are losing performance at a faster rate than what the warranty guarantees. If you notice a sudden dip in energy production, it’s most likely to be an issue with the panel materials. However, if your panels seem to be producing noticeably less energy over time, then contact your installation company for an assessment. If they feel that performance is the issue, then contact the manufacturer who should provide you with replacement panels. Some manufacturers will cover the shipping and replacement costs. Other Product Warranties You may also be able to receive a warranty on your solar system’s inverter and solar battery. An inverter is a device that changes the direct current that your panels produce into an alternating current, which is what all of your electronic devices need to function. Without an inverter, your solar panels would just be odd roof decorations that create a form of energy you couldn’t use! Inverters typically don’t last as long as solar panels, and most homeowners have to replace a system’s inverter at least once over the life of the system. As a result, inverter warranties tend to cover a shorter time than solar panel product warranties. Most inverter warranties last between five and ten years. The other type of warranty you may be interested in is a solar battery warranty. Solar batteries are increasing in popularity as they become more reliable and cost-effective. Solar batteries allow you to store the excess energy your panels generate for use at night or during other times your panels aren’t operating at peak efficiency. They can be useful if you live in an area without reliable utility power, or if you are making an effort to live off the grid. Most battery brands offer a warranty of five to 10 years, and you can expect top solar batteries to last around 15 years. Don’t Void Your Warranty! Investing in top-rated solar panels with the best warranties won’t help you one bit if you do something that voids your warranty. Read the fine print of the warranty document to ensure that you don’t put your warranty at risk. Generally speaking, you may void your warranty if you or an unlicensed worker modify or repair your system, or if you don’t provide basic protections to your system, like cutting back trees. Unrelated mistakes, like stepping on your system while putting up Christmas decorations, also won’t be covered by your warranty! It’s always a good idea to reach out to your original solar panel installation company if you notice a problem with your system. Make sure that a licensed installer assesses your panels and provides any needed modifications or repair in order to maintain your warranty. Choose Top Rated Solar Panels with Great Warranties A solar panel warranty isn’t useful… until it is! That is to say that a warranty can become extremely valuable if something goes wrong with your system. Most systems operate flawlessly, but it’s always smart to have a Plan B just in case. Your warranty is that Plan B. The better the warranty, the more protection you get on your solar investment, so consider paying a little more for top industry warranties. At Semper Solaris, we work with a wide variety of solar panel brands (unlike many other installation companies that only offer one or two brands). We are happy to provide solar panel recommendations and to help you choose the right solar panel for your roof, budget, and energy needs. Contact us for a free solar panel assessment today.
With the recent Pineapple Express storm pounding California with more rain and more extreme weather than usual, homeowners might be left wondering about the effect of weather on solar panels. Here’s what you need to know about how solar panels work and how weather may affect them. How Solar Panels Work without Sun The way solar panels work is because of a cell panel that converts sunlight directly into electricity. When photons (particles of sunlight) hit them on top of a roof, the panel turns the photons it receives into electrons of direct current electricity. The inverter then converts the direct current electricity into alternating current power, which can be used to power household items. A common misconception about solar panels is that they need direct sunlight in order to work. Although the sun is the main source of energy that they absorb and convert into power, the way that it is projected onto a solar panel cell doesn’t necessarily require direct sunlight. Solar panel cells actually just need the photons emitted from daylight sun. In other words, even if it’s cloudy out, the sun’s photons are still being spread into the atmosphere and absorbed into the panels. That being said, direct sunlight is still preferred over indirect sunlight for optimal energy absorption. On cloudy days, solar panels produce only 10 – 25% of their capacity. Factors that make this range an approximation include the density of the clouds, as well as the type of solar panel; some can handle diffused light better than others. Impact of Different Weather on Solar Panels Most solar panels are built to handle a wide range of climates and conditions, including heavy rain, hail, wind, heat and cold. This is good news for areas that are impacted by storms, rain and snow. During the manufacturing process, each solar panel is tested for extreme weather conditions to receive an Underwriter’s Laboratories (UL) certification. While this certification is a good baseline, it doesn’t mean that all solar panels uphold the same durability and quality. It simply means they have passed the minimum number of tests required to be certified. More specifically, high winds, snow, and cold temperatures shouldn’t be a concern. Top-rated solar panels are engineered to withstand winds of up to 140 MPH. As for harsh winters — cold temperature can actually improve solar panel output, and white snow can reflect light and improve photovoltaic performance. So long as panels aren’t covered in snow, winter climates can actually be an ideal environment for solar panels. Snow will usually melt and slide off panels easily; if it does build up, simply use a broom to brush it off. Of course, solar panels aren’t entirely invincible. Lightning and hail can damage solar panels in extreme cases. Consumers should look into their homeowner’s insurance policy, which usually covers solar panel damage if it is not included in the solar panel’s warranty. Additionally, be aware that hot climates may actually reduce the efficiency of solar panels. For any temperature above 87 degrees Fahrenheit, a one-degree increase in temperature can equate to a 1% decrease in efficiency. Durability of Solar Panels Most inclement weather won’t have a huge impact so long as they are high quality and boast durability as one of their main attributes. Many top-rated solar panels have a proven track record of durability, degrading at a slower rate than others. In fact, the manufacturer guarantees that the system will produce 92% of its rated power after 25 years of use. Durable solar panels also protect the roof of your home from harsh weather conditions, acting like a barrier. Panels are built to hold a certain weight, so the more durable your panels, the better they can withstand snow or hail. Proper Solar Installation to Withstand Any Weather Condition One key factor to ensuring weather doesn’t become a hindrance is making sure the panels are properly installed. Your money is on the line, so make sure the solar installation company that you go with is reputable among the solar industry. The installer should understand the types of local wind patterns and climate conditions your area typically receives, and help you pick the right solar panels to match these needs. Even if you live in California where the sunnier-than-average climate is ideal for solar , it’s normal to wonder how the weather might affect their efficiency. The science behind how panels absorb photons speaks to why they still work on cloudy days, and the durability of the panels allows them to withstand just about any weather scenario. At the same time, it’s important to choose the best quality solar panels and look for an installation company that can properly install panels so that they are secure and ready to face any weather condition. To find out more about what makes a top-rated solar panel worthy of installation, start by asking these 10 Questions About Solar Panels — that way you can ensure your panels will remain sturdy on your roof, whatever the weather may be.
The abundant sun and ideal climate makes California a fairly easy place to decide to switch from traditional to solar energy. The harder part, though, is choosing which of the solar power companies in California is the best for your solar installation. Competition is fierce and the vetting process can get overwhelming when you sift through all the options. To ensure you make the right choice, here are the top four qualities a legitimate, reliable and high-quality solar power company should have. 1. A Good Reputation in the Solar Community Googling “solar power companies in California” is likely the first step you take in your search for solar energy services. When the search results come up, and you click individual businesses that can fulfill solar panel needs, do your due diligence and see if the company has a good reputation. There are various angles you can look at that reflect the reputation of a business. Look at reviews and testimonials not only on the company’s website, but also from outside sources like Yelp. Also, check if there have been any mentions in the news for the solar businesses you find. For example, a solar company may be featured or talked about in a niche solar power publication. If the article is favorable to that company, it’s a good sign that they are likely reliable and respected in the solar community. How long an installer has been in the industry can also be indicative of the quality of work they will provide. In addition to internet research, keep your ears open for word-of-mouth buzz about solar power companies. California is an obvious place for solar installation and those neighbors of yours may have used a reliable and trustworthy installer in the past. Don’t discount first-hand accounts of the work a specific solar company can do—a lot of times, it’s a more powerful source than anything you can find online 2. Dedicated to Only Using the Top Solar Panels and Products As you do your research on solar installation providers, find out what type of solar panels and products each one is using. Remember that the quality of the products being installed is just as important as the quality of labor being provided. When assessing different solar power companies in California, check if prospective companies will provide a free evaluation. This is a good sign that a business doesn’t just provide the installation, but that it also offers expertise on the matter. The solar panel company should be able to provide an evaluation and options for the type of solar panels that are the best fit for your house. The amount of space where solar panels can be installed is a huge factor and will inform which category of solar panels to be used. Additionally, when a company uses solar panels that use the latest technology—it’s a good indication that they care that you get only the best product. Many top-rated solar panel manufacturers guarantee that the latest technology is used when it comes to solar energy. Finally, aside from the actual solar panels, look to see if a company uses roofing and installation products that promote durability. This factor is crucial to building a solid foundation for your solar panels to be placed on. 3. Personal Attention What sets a good solar power company apart from a great one is the personal attention a company provides you. The relationship between you and your solar company should be a strong one, built on trust. Look for solar power companies in California that are known to constantly keep communication open with their customers and make their customer’s happiness a priority. Semper Solaris’ motto focuses on core values like trust, loyalty and a hard work ethic. We believe in making solar a personal matter, engaging with customers face-to-face on a regular basis in order to establish a relationship that transcends beyond just solar installation. By doing this, we have the ability to address any issues immediately and provide greater quality service to each and every customer we work with. 4. Proper Certifications Be sure to weed out legitimate solar panel installers from other ones by checking certifications. In California, for example, some installers may be certified by the North American Board of Certified Energy Practitioners (NABCEP) to install photovoltaic (PV) and solar-thermal systems. This certification guarantees that they have at least one year of experience installing systems, have passed an exam and continue their education in solar panel installation for recertification every three years. A solar company should also hold general contracting, electrician and home improvement licenses as well as general liability insurance. Holding the proper certifications for such large home upgrade is crucial to ensuring that your solar panels are installed with the best quality labor that can be provided. As you go about your search for solar power companies, California’s saturated market can be an intimidating place to look. The installer you choose should have specific qualities, one of which includes a focus on providing personal attention and high-quality work with top-of-the-line solar panels. Additionally, a solar company’s employees should be qualified in the special trade work that’s about to be done on your home. It’s easy to assume that the labor you hire already holds those certifications, but double check on your end to avoid any problems with installation. Not all solar power companies are the same. Trusted work and reputation among the industry will help guide you in picking the right one to upgrade to the new way to save on home energy needs.
