Types of Solar Energy
The sun is one of the most valuable power sources available. To better understand the solar potential in our Georgia communities and decide whether it's an option for you, let's explore the different types of solar energy.
Solar Electric Power
This is what most people commonly think of when it comes to solar energy. Electricity is converted directly from solar energy through solar cells known as photovoltaic cells – "photo" for light and "voltaic" for energy.
Normally mounted on the roof or in a location with maximum sun exposure, the photovoltaic (PV) array components convert energy from the sun into electric current to power appliances and other household devices. A PV system requires little maintenance and can produce power for more than 20 years.
Solar Thermal Energy
Heating water using electricity can make up 14-25% of the average home's utility bill. A residential solar water heating system can be designed to meet between 50 and 80% of a home's water heating requirements.
A solar water heating system requires collectors to absorb the sun's energy and a storage system to hold the energy until it is needed. The systems used to store thermal energy are similar to conventional water heaters. The heated water is circulated through the home or building using pumps.
Georgia Power offers a $250 rebate for qualifying solar water heaters.
