How do the Panels Work?

Solar power is the result of converting sunlight into electricity. Solar panels are the technology mainly responsible for doing this. They use the “photovoltaic effect”, discovered by Edmund Becquerel in 1839, to produce electricity from the sun. Sunlight is converted to electricity using photovoltaic (PV), or solar cells.

Traditional PV Panels are made of semiconductor material and absorb sunlight. They usually contain a protective top layer, two layers of silicon with collecting circuitry attached to the top layer, and a backing layer.

When sunlight hits the top layer of a solar panel, it knocks electrons loose from the silicon. When the electrons are freed from the top layer, they are collected by the electrical circuitry and sent to an external circuit. This provides power to the electrical system.
