Choosing A Battery: How to Pick The Best Solar Battery for Your Home?
Picking up the correct solar battery is crucial from the standpoint of storing solar energy and ensuring an efficient, uninterrupted supply of electricity during the evening and night hours. However, how do you know if a Solar Battery Storage is worth the investment? In other words, how do you choose the correct solar battery for your home? That demands some research and a thorough consideration of a few essential factors. Let’s see what those are.
How to Select the Right Solar Battery for Your Home? – Tips to Choose The Best Solar Battery for Your Home
Selecting the right solar battery for your home isn’t rocket science. However, it requires you to be concerned about a few essential factors. Therefore, the following factors matter.
Solar Panel Battery Storage
The Battery capacity refers to the amount of electrical power that can it can store. We measure it in kilowatt-hours. In simple words, it is the battery’s size. However, the parameter does not tell the amount of power, which we can withdraw from the battery at a time. Hence, you must consider the power rating as well, which means the amount of energy the battery can provide momentarily. A high-power and low-capacity battery can power the entire house for many hours. On the other hand, a low power and high-capacity one can provide little energy for a longer duration.
Round Trip Efficiency
This factor relates to the usable amount of electricity that is fed into the battery. It is expressed in percentage. For example, suppose a battery is charged with 6 kilowatt-hours of power, and it can provide 5 kilowatt-hours of usable power; the round-trip efficiency is approximately 83-85%. You must choose a battery with a high round trip efficiency.
Depth-of-discharge refers to the amount of electricity withdrawn from the battery. Battery manufacturers inform about the optimal possible depth-of-discharge. A battery with a 5 kilowatt-hours capacity and an 80% depth-of-discharge will allow using up to 4 kilowatt-hours before it requires charge again. The depth of discharge and the capacity of the battery are directly proportional.
Suppose a battery offers a 5,000-cycle or 10-year warranty at 80% of its initial capacity. Then, it refers to the battery losing up to 20% of its energy-storing capacity by the end of the warranty period. Manufacturers will indicate the warranty. So, ensure you know well about the battery’s warranty.
Battery lifespan is another significant factor. Most last five to 15 years on average. So, while choosing a Solar Battery Storage, ensure you also check its lifespan. Have more questions?
