Frequently Asked Questions
The larger the area of PV panels, the more electricity is generated. A typical residential 5 kilowatt system, for example, may produce about 10,000 kilowatt-hours a year. Over a 25-year lifespan, this comes out to be 250,000 kilowatt-hours.
Many factors are involved in determining your PV system output. The weather, temperature, shading, tilt, orientation, and other factors can affect the performance of your system. We are able to use well established averages to advise you about system performance. Your system output will vary over time, sometimes significantly outperforming the averages and sometimes falling short. Because a grid-tied system is connected to two power sources (the utility company and the solar electric system) you will always have all of the power you need.
