At present, the most common photovoltaic system is the household photovoltaic system.Household photovoltaic systems are mainly small power photovoltaic systems, such as 3KW,5KW,6KW,8KW and grid-connected 6KW,10KW,15KW,20KW, and hybrid photovoltaic systems 5KW, 8KW. There are 3 types of photovoltaic systems, off-grid, grid-connected, and hybrid.

Photovoltaic system components include solar panels, solar panel brackets, bus boxes, inverters, batteries, cables.

The quoted composition of the photovoltaic system: solar panel + solar support + bus box + inverter + cable + battery
