How Solar Panel Works

Lesson Progress
0% Complete

Solar panels work by absorbing sunlight with photovoltaic cells, generating direct current (DC) energy and converting it to usable alternating current (AC) energy with the help of an inverter. AC energy then flows through the home appliances and electrical panel and is distributed accordingly. 

In general, a photovoltaic solar cell generates electricity as follows:

1. The silicon photovoltaic cell absorbs solar radiation.

2. When sun rays interact with the silicon cells, electrons begin to move.

3. Moving electrons create a flow of electric current captured by nodes and wiring in the panels.

4. Wires feed this direct current (DC) electricity to a solar inverter to be converted to alternating current (AC) electricity.
