Choosing the Right Battery for Solar Panels: A Guide

Shopping for solar panel batteries can get overwhelming, especially if you don’t know where to start. There are many options available in the market, and solar energy storage is still a relatively new concept for most residential and commercial property owners. However, there have been significant improvements in solar battery technology, and with the introduction of custom lithium-ion battery packs, homeowners are undoubtedly enjoying greater utility and returns on their solar investments.

That said, you should always do your due diligence before selecting a battery pack that suits your unique needs and requirements. To help you with your solar panel battery selection process, here are some key factors you should keep in mind when going battery shopping.

Capacity Rating

The battery’s capacity indicates its ability to store electricity, measured in kilowatt-hours. The usable capacity provides information on how long the battery can send electricity to your home. Some batteries may show total and usable capacity as two different readings; focus on the usable capacity.

Select the battery that provides a capacity rating that fulfills the unique requirements of your home or commercial space. You can always install multiple batteries to increase the amount of electricity storage later.

 

Power Rating

A battery power rating determines how much energy the battery can provide at once. The rating provides guidelines on how many appliances you can run at once. Solar batteries usually have two rating indicators: continuous power rating and peak power rating.

The continuous power rating is the amount of power the battery can provide nonstop, while the peak power rating is the maximum energy your battery can release in a given time. If you want to power multiple appliances simultaneously, consider purchasing a battery with high power ratings.

 

Lifespan

Most solar panel batteries have a life of around ten years with regular usage. As you use the batteries daily, they degrade and lose their ability to hold a charge. Therefore, finding a battery with a decent lifespan is important to ensure you get the maximum return on your investment. There are three ways through which a battery’s lifespan is calculated:

  • Years
  • Cycles

The battery’s lifecycle is the number of times the cells can be fully charged and discharged. The throughput is the estimated amount of energy the battery will release over a certain period.
