Frequently Asked Questions

Solar power is electricity that is generated from the sun's energy. Solar power is an infinitely renewable resource, giving it the unique ability to generate energy that is clean, quiet, and consistent.

Home solar power is based on photovoltaic (PV) panel technology. PV panels use a semiconductor material like silicon, along with elements like phosphorous and boron that create conductivity within the photovoltaic cells. The sun’s energy activates the electrons in the elements, which move across the cell to create electricity. This electricity is created as direct current (DC) power, which PV panels change into alternating current (AC) power suitable for use in your home using an inverter.

No. Unlike other technologies like computer chips, photovoltaic technology is not subject to Moore's Law. Instead of rapid performance gains, PV technology has slowly improved over time, which means there is no need to hold out for major advances on the horizon, since they won't offset the savings you could be receiving now.

Yes. A home solar power system is interconnected with the grid, and is designed to work with your utility company to provide consistent power. During the day, solar power will be the primary source of electricity for your home. If your system produces more electricity than your home is using, you may be eligible for net metering that credits you for the excess power that you generate and return to the grid. At night, and if your electricity demands exceed the power produced by your solar system, your utility company will provide you with power to match your needs. Systems are also available with a battery backup that charges during the day when your system is producing excess power, and provides power back to you at night and in the event of a power outage.
