Solar batteries are the application of batteries in solar photovoltaic power generation. Currently, there are four types of batteries used: lead-acid maintenance free batteries, ordinary lead-acid batteries, colloidal batteries, and alkaline nickel cadmium batteries. The main solar batteries widely used in China are lead-acid maintenance free batteries and colloidal batteries
