Choosing the best battery in that market involves considering a few factors, such as its capacity, power, efficiency, or how much it will cost. Solar batteries are the best way to generate backup power. If you live in an area where utilities are unreliable, or if you desire to go off the grid while using renewable energy, solar batteries are worth it. If you are thinking of ways to store energy generated by your solar panels, it’s best to invest in Solar Battery. If you don’t have a battery and you aren’t connected to the grid, this means you will have no backup power when your neighborhood has an outage. Therefore, batteries are crucial to keeping your system running consistently. There are a lot of batteries in the market but we recommend the following:
- Sonnen Batteries
- LG Chem solar battery
- Panasonic Evervolt
How To Compare Solar Batteries?
Capacity: It’s measured in kWh and is the total amount of electricity that your solar battery will store.
End of Life Capacity: The moment where the solar battery reaches the end of its life and is no longer able to operate at its peak capacity.
Depth of Discharge (DoD): This term is used to indicate the percentage of the battery’s energy that has been discharged relative to its overall capacity. Over time, for optimal battery performance, a specific maximum of DoD is recommended. This changes and is specific to the battery – the higher the DoD means that it’s considered a better quality battery.
Warranty: Battery’s performance will decline over time and a good warranty will guarantee good performance for years. Also, it will ensure that the battery will maintain a certain capacity.
Round-trip Efficiency: It’s the difference between the amount of solar energy that is needed to charge it and the available amount. It’s best to look for one that has more than 80% efficiency.
Life Capacity: As time goes on, the battery will start to lose its ability to hold a charge. All the batteries in the market lose their abilities over time but it’s important to choose one that will hold that charge for longer.
