Battery types for solar power. Batteries are classified according to the type of manufacturing technology as well as the electrolytes used. The types of solar batteries most used in photovoltaic installations are lead-acid batteries due to the price ratio for available energy. Its efficiency is 85-95%, while Ni-Cad is 65%.
In stand-alone photovoltaic power systems, the electrical energy produced by the photovoltaic panels cannot always be used directly. As the demand from the load does not always equal the solar panel capacity, battery banks are generally used. The primary functions of a storage battery in a stand-alone PV system are:
