How Do Solar Power Shingles Work?


Quick Answer

When sunlight is introduced to the solar cells located within solar-powered shingles, photons released by the sun are absorbed, in turn releasing electrons that create an electrical current. The electricity produced then enters the home through a wire connected to the home's solar inverter, which converts the direct current to a usable alternating current that is fed into the electrical distribution panel to power electrical devices.

The solar inverter takes the energy produced by the direct current generated by the shingles and converts it to a usable alternating current, which is fed into the electrical distribution panel to power the home or location harnessing the solar energy. The solar inverter allows multiple lines of shingles to operate independently of one another to maximize power generation from shingles that may be installed on different portions of the roof to manipulate energy based on such factors as the time of day and angle of the sunlight.

The average residential solar energy system offsets 30 to 60 percent of an average home's energy consumption overall. The specific amount of solar energy captured per day is influenced by many factors, such as location, weather and orientation of the home and placement of the shingles at a specific time of day. The dimensions of any solar array are dependent on the homeowner's goals, cost criteria, energy consumption and the current efficiencies and size of the home. All of these factors can directly correlate to the level of energy produced by the shingle system.
