A worked example: 8 kW in Yuma
An 8 kW system — about 19 × 425-watt panels — at Yuma's assumed installed cost of $2.40–$3.15 per watt runs roughly $19,200–$25,200 before incentives. At about 1,800 kWh per installed kW, it would generate around 14,400 kWh per year. Valuing self-consumed electricity at the assumed $0.16/kWh retail rate and exports conservatively, first-year savings land near $1,898 — a simple payback of roughly 10–13 years.
No federal tax credit is included: the Section 25D residential credit ended for systems installed after December 31, 2025.
Average cost of solar panels in Yuma by system size
At the Yuma market rate of $2.40–$3.15 per watt, using the local production factor rather than the Arizona average:
| System size | Panels | Installed cost | Annual production | Est. payback |
|---|---|---|---|---|
| 6 kW | 15 | $14,400–$18,900 | 10,800 kWh | 10–13 yrs |
| 8 kW | 19 | $19,200–$25,200 | 14,400 kWh | 10–13 yrs |
| 10 kW | 24 | $24,000–$31,500 | 18,000 kWh | 10–13 yrs |
| 12 kW | 29 | $28,800–$37,800 | 21,600 kWh | 10–13 yrs |
Over a 25-year life, solar electricity in Yuma comes to roughly 5.7¢–7.4¢ per kilowatt-hour, against a local retail rate assumed at 16.0¢.
How Yuma differs from the Arizona average
Statewide averages blend climates, utilities and installer markets that can differ sharply within a single state — which is why a Yuma estimate is not simply the Arizona number.
| Assumption | Yuma | Arizona average |
|---|---|---|
| Electricity rate | $0.16/kWh | $0.16/kWh |
| Production (kWh/kW/yr) | 1,800 | 1,720 |
| Installed cost per watt | $2.40–$3.15 | $2.35–$3.10 |
| 8 kW system cost | $19,200–$25,200 | $18,800–$24,800 |
| Estimated payback | 10–13 yrs | 10–14 yrs |
APS (Arizona Public Service) and solar exports
Yuma is APS territory, so the same below-retail Resource Comparison Proxy export rate applies as in Phoenix, locked in for 10 years at the rate in effect when the system interconnects.
Statewide, arizona replaced retail net metering with net billing. Utilities such as APS and SRP credit exported solar at an export rate below retail that can step down annually, so self-consumption drives most savings.
Local factors that change a Yuma solar quote
The extreme production factor makes Yuma one of the few markets where a smaller system can fully cover a large bill. Dust accumulation is a real and often-overlooked production loss here; panels in desert conditions benefit from occasional rinsing, and quotes rarely price that in.
Beyond location, equipment, roof condition, electrical upgrades, permitting, labor, system size, batteries and financing all move the installed price.
Solar incentives available in Yuma
Arizona offers a state income tax credit of 25% of system cost up to $1,000, plus sales and property tax exemptions for residential solar. Verify current program terms.
There is no federal residential credit for systems installed in 2026, so state, local and utility programs are now the entire incentive picture for a purchased system. See the full Arizona solar incentives guide.
Frequently asked questions
What is the average cost of solar panels in Yuma?
Averaging the Yuma market at $2.40–$3.15 per watt installed, a 6 kW system runs $14,400–$18,900, an 8 kW $19,200–$25,200, and a 10 kW $24,000–$31,500, all before incentives. Over a 25-year life that is roughly 5.7¢–7.4¢ per kilowatt-hour, against a local retail rate assumed at 16.0¢.
How much does it cost to install solar panels in Yuma?
The per-watt figures above are turnkey: panels, inverter, racking, labor, permitting and interconnection. What moves a Yuma quote away from them is local: The extreme production factor makes Yuma one of the few markets where a smaller system can fully cover a large bill. Dust accumulation is a real and often-overlooked production loss here; panels in desert conditions benefit from occasional rinsing, and quotes rarely price that in. Roof complexity and a main-panel upgrade are the other two big swings, and only a site visit settles either.
How much do solar panels cost in Yuma, AZ?
At an assumed installed cost of $2.40–$3.15 per watt for the Yuma market, a typical 8 kW home system runs roughly $19,200–$25,200 before incentives — about 19 panels at 425 watts each. That is 2% above the Arizona statewide assumption, reflecting local installer competition.
How much electricity does a solar system produce in Yuma?
We assume about 1,800 kWh per installed kW per year in Yuma — so an 8 kW system generates roughly 14,400 kWh annually. That is 5% above the Arizona average, because statewide figures blend climates that can differ sharply within one state.
Is solar worth it in Yuma?
With electricity around $0.16/kWh and 1,800 kWh/kW of annual production, an 8 kW system in Yuma could save roughly $1,898 in year one — a simple payback of about 10–13 years with no federal tax credit. Whether that clears your bar depends on your rate plan, how much of the output you use on site, your roof, and how long you plan to stay.
Who is the electric utility in Yuma and how does it pay for solar exports?
APS (Arizona Public Service). Yuma is APS territory, so the same below-retail Resource Comparison Proxy export rate applies as in Phoenix, locked in for 10 years at the rate in effect when the system interconnects.
Is there still a federal solar tax credit in Yuma?
No — the 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. None of the figures on this page include it. Leased or PPA systems may still benefit indirectly, because the system owner can claim the commercial 48E credit through 2027.

These are broad local assumptions, not a market survey of Yuma installers or a binding quote. Before purchasing, verify applicable incentives, your specific utility tariff, installer licensing, warranties and financing terms.
