The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is. .
The useful life of a battery for solar installations is usually around ten years. However, their useful life plummets if frequent deep discharges (> 50%) are made. Therefore, it is. .
Batteries are classified according to the type of manufacturing technology as well as the electrolytesused. The types of solar batteries most used. Solar panels can work without a battery. However, without a battery to store the energy your panels produce, you can only use solar electricity while the sun is out. [pdf]
