1: Solar photovoltaic panel is the first component that collects sunlight energy and converts it into electrical energy.
Generally divided into two types, monocrystalline silicon and polycrystalline silicon. Monocrystalline silicon has a higher conversion rate than polycrystalline silicon.
2: Controller. Generally, the electricity from solar photovoltaic panels is unstable. The voltage and current change with the change of sunlight intensity. Therefore, a controller is needed to prevent overcharging and overcharging when charging the battery. put.
3: Batteries are generally lithium batteries, and 18650 and 32650 batteries are available for more mature products in the market.
4: Lamp holder, generally LED lamp holder, power depends on the size and number of LED chips.
