Photovoltaic Solar Installations
Photovoltaic Solar Panels take the energy produced by the sun and turn it into electricity through solar cells. There is virtually zero environmental impact and, besides the cost of the equipment, production of energy with solar panels is 100% free. Sun is converted by the panel to direct current (DC) electricity and is then sent to an inverter which converts the electricity to alternating current (AC), the kind of electricity used in your home.
