FAQs on Phoenix Solar Panels

1. Can you sell excess solar energy back to the grid in Phoenix?

Yes, but not at the full retail rate. Utilities in Arizona use net billing, which means when your solar panels produce more than you use, you earn credits at a lower rate than what you pay for electricity.

2. Does solar increase home value in Phoenix?

Homes with owned residential solar panels in Phoenix often see higher resale value. On average, buyers pay more for houses with solar panel systems, especially when the system is fully paid off.

3. How fast do solar panels pay themselves off in Phoenix?

For most homeowners, the cost of solar panels in Phoenix is recovered in about 10 to 12 years. After that, the energy your system generates is essentially free for the rest of its lifespan.

4. Will my power utility still accept excess solar energy?

Yes, if your Phoenix solar panels produce more than you need, utilities like APS give you credits through net billing. The credits are lower than the retail electricity price, but still reduce your monthly bill.

5. Are community solar programs available in Arizona?

Some options exist for solar in Phoenix through community programs, which let you buy a share of solar energy without installing panels on your own roof. This is helpful if your roof is shaded or not suitable for solar panel installation.
