Solar batteries are believed to be a smart investment for energy storage. You cannot generate enough energy for later use if you don’t invest in a battery bank. So, choosing a good solar panel battery is a crucial decision and it is dependent upon factors like the capacity of the battery, efficiency, power, and costs.

Working of Solar Batteries

When you install a solar panel battery as a part of your solar panel system, you have to store excess solar energy instead of sending it back to the grid. If more energy is produced by the panels, this energy goes back into charging your battery. When solar panels aren’t producing enough electricity, the stored energy from the battery can be used.

Types of Solar Batteries

You can pair these 4 kinds of batteries with residential solar systems-

  • Lead-acid Batteries– these are deep-cycle batteries that are used to store energy for a long period of time. They are cheap, reliable, and can be easily disposed of or recycled.
  • Flow Batteries– These batteries are quite new in the industry. They contain a water-based electrolyte liquid flowing between two tanks within the battery. These batteries are large and have a 100% depth of discharge which means that all the energy can be used without affecting the battery’s health.
  • Lithium-ion Batteries- These are relatively new kinds of batteries that are used in the electric vehicles. They are becoming one of the most widely used solar battery banks. They have a higher battery energy density, do not require high maintenance, have a longer lifespan, and also have a higher depth of discharge.
  • Nickel-based Batteries- Also known as Nickel-cadmium batteries are a favorite amongst the aircraft industry. The main benefit of this battery is that it is durable, can operate at extreme temperatures, and is maintenance-free.

Choosing The Right Solar Battery for You

As per the general scenario, the best battery for a home solar installation is a lithium-ion battery because it can hold more energy in a given amount of space, have high efficiencies, and have the ability to discharge most of its stored energy.

The Lead-acid battery is a good choice for you in case you have a restricted budget. You can use this battery for decades and these batteries come at a low cost.

Conclusion

When there are so many options for solar panel battery in the market, you would want to compare each type of battery based on its capacity, depth of discharge, round-trip efficiency, and battery life & warranty. The right battery for you is the one that sinks with your application, falls under your budget, and meets your expectations for upkeep like regular maintenance and replacement interval. Your living situation will define your choice of the smartest battery. You will be amazed to know that nowadays, solar panels for agriculture are also in high demand because people are realizing the benefits of going solar. They also want to contribute to utilizing the renewable form of energy for power generation instead of non-renewable forms like coal and fossil fuels.
