Ⅲ. Basic composition of solar garden lamp:


1. Solar photovoltaic panel: the first component that collects sunlight energy and converts it into electric energy. It is generally divided into monocrystalline silicon and polycrystalline silicon. The conversion rate of monocrystalline silicon is a little higher than that of polycrystalline silicon.


2. Controller. Generally, the electricity generated by solar photovoltaic panels is unstable whose voltage and current change with the change of sunlight intensity. Therefore, a controller is needed to prevent over-charge and over-discharge when charging the solar garden lamp battery.


3. Battery. Generally, they are lithium batteries. 18650 and 32650 batteries are relatively mature products in the market. The diameter of the 18650 battery is 18mm, and the capacity is generally about 2000mah-3000mah. The diameter of the 32650 battery is 32mm, which is relatively thick and has a large capacity, generally about 5000mAh. If you need a high-capacity battery, add a few more batteries.
