What Is a Solar Power System?

A solar power system converts sunlight into usable electricity for your home.

The system typically consists of:

• Solar panels

• Solar inverter

• Battery storage (optional)

• Mounting equipment

• Monitoring system

• Electrical wiring

Solar panels collect sunlight and generate direct current (DC) electricity. The inverter converts this DC electricity into alternating current (AC), which powers household appliances.

Excess energy can either be stored in batteries or sent back to the electrical grid.
