Solar panel: After converting the sun's light energy into electric energy, the output direct current is stored in the battery. The solar panel itself does not have a power storage function.
Solar controller: protect the battery from recoil, short circuit, overcharge and overdischarge, etc. Effectively extend the service life of the battery.
Battery: Store the electricity converted by solar panels for electrical appliances.
Inverter: The inverter converts direct current (battery, storage battery) into alternating current.
Core components required by the system

Installation of solar energy system
Installation method and requirements
The panel is facing south at 25~35 degrees on the ground (facing the sunlight). Do not put the panel flat in front of the object blocking the light, as this will lead to a low power generation
