Salt River Project (SRP): how it credits the solar power you send to the grid
3.45 cents per kWh for exported power on SRP's export price plans (E-13 and E-14); its demand plans (E-15 and E-27) net usage instead but add a demand charge. These plans close in November 2029.
Checked November 12, 2026. Utilities change these rules; check the current tariff before you sign.
How it works
Salt River Project (SRP) credits exported power at 3.45 cents per kWh, about 23% of Arizona's average electricity price.
SRP is a public power district, so the Arizona Corporation Commission's 10-year lock doesn't apply: SRP's board sets the export price, and it can change.
Solar customers choose between export plans, where every kWh sent out earns 3.45 cents, and demand plans, where the bill includes a charge based on your highest use during on-peak hours.
SRP plans to move all solar customers to new plans (E-16 and E-28) by the November 2029 billing cycle, with lower credits for midday exports.
Tip: Run the numbers both ways: a battery that trims evening peaks can make a demand plan cheaper.
What it means for a typical Arizona home
An average Arizona home uses about 12,360 kWh a year. A 6.5 kW system costs about $16,705 at the 2026 median price and makes about 11,408 kWh in its first year, of which we assume about 6,845 kWh goes out to the grid because no one is home to use it.
| First-year savings | Payback | 25-year savings, after the price | |
|---|---|---|---|
| With Salt River Project (SRP)'s credit | $932 | 18 years | $10,490 |
| If every exported kWh earned the full price | $1,741 | 9 years | $36,340 |
The difference, about $25,850 over 25 years, is what Salt River Project (SRP)'s rules cost a typical system compared with full net metering. Using more of the power at home, while the sun is up, closes some of that gap. Uses Arizona's average electricity price; Salt River Project (SRP)'s own prices may be higher or lower. Paid in cash, no federal credit, prices rising 2.5% a year, one inverter replacement.
