Capacity selection of solar battery

The most professional solar cell sharing

The input energy of solar photovoltaic power generation system is extremely unstable, so it generally needs to be equipped with battery system to work, and solar lamps are no exception, which must be equipped with battery to work. Generally, there are lead-acid batteries, Ni-Cd batteries and Ni-H batteries. Their capacity selection directly affects the reliability and price of the system. The selection of battery capacity shall generally follow the following principles:

On the premise of meeting the lighting at night, the energy of solar cell modules during the day shall be stored as much as possible, and the electric energy required for night lighting in continuous rainy days shall be stored at the same time. The battery capacity is too small to meet the needs of night lighting. The battery capacity is too large. On the one hand, the battery is always in the state of power loss, which affects the service life of the battery and causes waste.
