Solar Roofing FAQs
How soon will I begin to see my energy bills reduced?
Immediately! You should see a lower electric bill the very first month your GAF Solar roofing system goes into operation.
How does a solar roof generate electricity?
A GAF solar system generates electricity through the use of photovoltaic (PV) technology which turns the sun’s light energy into direct current (DC) electricity. After passing through a component called an inverter, the (DC) electricity is converted to alternating current (AC), the type of electricity that you access through the outlets in your home.
Do I still need electricity from the utility?
While you generate much of your own electricity during the peak hours of daylight and demand, your utility can supply your electricity at night and on very cloudy days.
Will the roof produce enough power for all my home’s electrical needs?
The amount of electricity generated depends upon several factors. These include system size, location, and environmental conditions. If you have enough space, a solar power system can be custom-sized to meet all of your electricity needs. It is rarely necessary for a system to cover all of your electricity needs to be cost-effective. In most cases, simply eliminating the peak periods of energy consumption has a noticeable effect on monthly utility bills.
What happens at night?
Since photovoltaic technology requires sunlight to generate electricity, your system will not produce during the night or on very cloudy days. Unless you purchase a system with a battery backup, your local utility will continue to supply your electricity at night. During sunny days when your solar system generates more power than you need, you send the excess energy back to the utility grid. When the sun goes down, you retrieve that energy from the grid.
What about cloudy days?
Electrical output depends on the amount of sunlight available at any given time. While your system will produce the bulk of your electricity when it is sunny, it can generate 50 — 70% of that output under bright overcast conditions. As cloud cover thickens, production will continue to diminish as less light reaches the surface of the modules.
Will my electric utility company credit me for power I send back to the grid?
Although specific policies vary from utility to utility, net metering is a regulation that requires utilities to allow excess energy generated by solar electric systems to be sent to the grid. This arrangement allows all electricity produced by your GAF Solar roof to be used to offset the remaining portion of your utility bill. The excess electricity is received as a credit. You will not receive a check for the excess power.
