With the help of solar battery storage, you can keep the excess energy that your solar panels produce during the day. So, it provides you the option to use that stored excess energy as and when you need it. Most homeowners use it during a power outage or other such similar scenarios. However, recently many are using it to control their utility rate and also to increase their savings. Thus, it is no wonder that more than 50% of the US population is considering adding a battery to their existing solar battery installation. When diving into the world of solar batteries, the very first thing which a homeowner notices is a price. So, it is quite natural for a homeowner to know how long the charge of a solar battery will last or what is the life expectancy of the selected/wish-listed solar batteries before going for this kind of significant, long-term investment. How long will the charge on battery storage last for? Well, home solar battery units usually last for 5 to 20 years. In fact, many manufacturers and suppliers guarantee that you won't need to replace the batteries until after almost 30 years from the date of purchase. This development is rather recent, along with the increase in the life expectancy of solar panels. Such an advantage is expected from solar batteries as well. However, it is tough to procure the exact hours the charge of the solar battery in question will last. Based on the type, model, kind, capacity, size of the solar battery, and the amount of charge provided to it, a standard battery charge lasts for 1 to 5 days’ load. Specific batteries, like Tesla Powerwall, will give 7+ continuous days of power.** So, it is quite clear now that the charge will be affected by the types of battery and along with factors known for impacting the solar battery’s lifespan and capacity. Thus, to provide a clearer picture; next, we will discuss the different factors affecting the battery life along with the best types of solar battery known for holding the charge for an extensive amount of time: Types of Solar Battery There are three popular solar battery types which are known for lasting for a long time after a single proper charge, and they are: Saltwater Battery Instead of heavy metals, it depends on saltwater electrolytes. These are environment-friendly and recyclable. Lead-Acid Battery Even with a lower DoD (Depth of Discharge) and shorter lifespan compared to the next type, lead-acid battery works well and is affordable. Lithium-Ion Battery This type is more expensive than both types discussed above; however, it is one of the best options to go with if you are looking for a solar battery that has reasonable charge retaining capacity. Saltwater and lead-acid are indeed great performers; however, the charge of lithium-ion solar batteries will last longer than the other two. Other Factors Affecting Solar battery’s lifespan Solar Battery Charging and Maintenance A solar battery will need charging as per its type, model, and size. Only with the correct or proper amount of charging, one can enjoy the product’s potential to the fullest. Thus, figuring out the charging time/period is crucial. Similarly, taking proper care of the batteries is also essential to ensure it is in working order and is capable of holding the charge for as much time as possible. Solar Battery Temperature The temperature/atmospheric condition of where you live will also affect the lifespan of a solar battery. Thus, protecting and charging the battery adequately is necessary. Solar Battery Usage The lifespan of the battery or the charge holding capacity of a solar battery will depend on its usage cycles. Thus, it is best to go for deep-cycle batteries. They are known for only discharging around 80% of the stored energy before it re-charges. There you have it, everything you needed to know to determine how long a solar battery can hold its charge. So, before investing in a battery, is it advisable to go over the information provided by the manufacturer and suppliers, and take the necessary steps to clear any queries to figure out how long you can expect the charge of a particular battery in solar panels to last.
