Q: How am I credited for electricity I sell back to the utility?

A: TEP customers receive retail credit for the electricity they send back onto the grid. On an annual basis, they will not be credited for electricity beyond what they use in that year.

Trico customers receive wholesale credit for the electricity they send back onto the grid. They receive a check at the end of the year for the total amount of electricity provided to Trico.

Q: I am using “Time of Use” metering. How will installing a solar electric system affect this service?

A: TEP customers using “Time of Use” metering will not be credited for electricity they send back to the grid. As an alternative, they can discontinue “Time of Use” metering and elect to use “Net Metering” instead. “Net Metering” tracks the electricity you provide to TEP, the electricity you buy from TEP, and the net difference of these values.

Trico customers can use “Time of Use” metering along with net metering.

Q: What maintenance is required once my solar electric system is installed?

A: No maintenance is required. You can increase annual system production by approximately 2% by washing your PV panels once a month. Simply wash with water and a squeegee. An additional 5% gain in system production can be achieved by changing the tilt angle of your array each season.

Q: Can my Home Owners Association (HOA) prevent me from installing a solar electric system on my house?

A: No. Arizona state statute (July 2007) specifically addresses the right for homeowners to install a solar electric system on their home. HOAs cannot require any changes in the solar electric system which would make it significantly more costly or reduce system efficiency.
