Solar panels in Alaska
Roofs across Alaska get about 1,024 hours of usable sunlight a year, and electricity costs 25.0¢/kWh. That combination puts a typical system's payback at 9.4 years. Here's the detail, from real rooftop data across 2 Alaska cities.

How Alaska compares
Alaska gets more sunlight than 0% of the cities we measure, and its electricity costs more than 89% of states and provinces. Both matter, but not equally: the electricity rate usually matters more, because solar saves money by replacing power you would otherwise buy. A sunny state with cheap power often pays back slower than a cloudy state with expensive power. Why that happens →
Solar by city in Alaska
| City | Sun hrs/yr | Panels | Net cost | Payback |
|---|---|---|---|---|
| Anchorage | 1,024 | 32 | $25,536 | 9.4 yrs |
| Fairbanks | 954 | 34 | $27,132 | 10 yrs |
What a system costs in Alaska
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 2,785 | $6,384 | $696 | 9.2 yrs |
| 12 panels | 4.8 kW | 4,178 | $9,576 | $1,044 | 9.2 yrs |
| 16 panels | 6.4 kW | 5,571 | $12,768 | $1,393 | 9.2 yrs |
| 20 panels | 8 kW | 6,963 | $15,960 | $1,741 | 9.2 yrs |
| 26 panels | 10.4 kW | 9,052 | $20,748 | $2,263 | 9.2 yrs |
Payback stops improving as systems grow, then gets worse. You can only save on electricity you were going to buy, so once a system covers your usage the extra panels mostly export at a lower rate.
Alaska solar incentives
Every US household can claim the 30% federal residential clean energy credit, which is what the "after credit" figures above assume. On a $36,480 system that is $10,944 back. How the credit works →
State, utility and municipal incentives stack on top and change often — Alaska may offer rebates, property or sales tax exemptions, or performance payments. We deliberately don't list specific state programmes here because they change several times a year and stale numbers are worse than none. The DSIRE database is the standard reference and is kept current.
Alaska solar questions
Is solar worth it in Alaska?
At 25.0¢/kWh and 1,024 usable sun hours, a typical Alaska system pays back in about 9.4 years and returns roughly $42,497 across a 25-year panel life. That is a solid return, and rising electricity prices only improve it. Individual cities in Alaska vary widely around this average.
How many solar panels do I need in Alaska?
About 32 panels for a home using 10,800 kWh a year. Each 400W panel produces roughly 348 kWh annually at Alaska sunlight levels. Your own figure depends on actual usage — pull a year of bills rather than assuming average consumption, since heating and EV charging change it a lot.
How much do solar panels cost in Alaska?
A 12.8 kW system runs about $36,480 before incentives and $25,536 after the 30% federal credit, or roughly $2.85 per watt installed. Quotes vary widely by installer, roof complexity and whether your electrical panel needs upgrading — get three before deciding.
