Written by Dean Mahmoud, CEO, and checked by Trevor Guilday, founder.Prices from the September 2026 Cost Index. Co-op credits read September 29 to October 14, 2026. Updated October 14, 2026.
A typical Alaska home system is 7.77 kW and costs about $24,476 in cash at $3.15 per watt. In our two worked cases it pays for itself in 20.9 to 28.2 years. Power you use within the month saves the full price, 26.85¢ on average. Surplus left at the end of the month earns your co-op’s much lower credit.
Free for you. Solar providers pay us when you ask for quotes. How we make money
Alaska settles each monthly bill on its own. A kWh your panels make is worth one of two very different amounts, depending on whether you use it that month. Our cases assume 40% is used at home as it is made.
| Co-op and surplus credit | Year-one savings | After upkeep | Simple payback |
|---|---|---|---|
| Golden Valley, 13.726¢ (September 1 to November 30, 2026) | $1,406 | $1,173 | 20.9 years |
| Chugach, 6.831¢ (tariff Sheet 97, from July 1, 2026) | $1,100 | $867 | 28.2 years |

Both cases treat every kWh sent out as month-end surplus, so they are the slow end. Power you send out and buy back within the same month saves the full price, and a home that uses more of its output each month pays back sooner.
Four electric co-ops serve about 78% of Alaska’s home electric customers. The state rules are the same for all four. The credit for surplus is not, and each co-op resets it during the year.
Anchorage area, about 1 in 3 Alaska homes. Posted rate from July 1, 2026; it changes with each quarterly cost-of-power adjustment. $270 to apply.
Next: ask Chugach for this quarter’s rate in writing.
Fairbanks and Interior Alaska, about 14% of homes. This rate runs September 1 to November 30, 2026. $65 to apply.
Next: ask which quarter’s rate the quote uses.
Mat-Su Valley and Eagle River, about 22% of homes. Its surplus rate resets each quarter and was not posted when we checked. No application fee.
Next: get this quarter’s rate from MEA in writing.
| Co-op | Credit per kWh of surplus | Rate period | Application fee | Share of Alaska homes |
|---|---|---|---|---|
| Golden Valley | 13.726¢ | Sep 1 to Nov 30, 2026 | $65 | about 14% |
| Chugach | 6.831¢ | From Jul 1, 2026; a lower rate is filed | $270 | about 1 in 3 |
| Matanuska | Ask MEA | Resets each quarter | None | about 22% |
| Homer | Ask HEA | Resets each quarter | Ask HEA | about 10% |

Homer Electric Association (HEA) serves the Kenai Peninsula. It takes systems from 0.4 kW up to the 25 kW state limit and uses a surplus rate that can change each quarter. Its website did not load when we checked, so ask HEA for this quarter’s rate and any fee, in writing.
The state rules cover utilities whose rates the Regulatory Commission of Alaska (RCA) regulates. A stand-alone grid that sold less than 5,000,000 kWh in the past year is exempt, and so is one that runs fully on renewable power. Utilities outside the rules set their own terms, so ask yours before you buy.
Shares are of Alaska’s home electric customers in 2024 (EIA Form 861). The Railbelt is the connected grid that links the four big co-ops.
An Alaska co-op can stop taking new solar homes once its program is full. Ask yours, in writing, whether it still takes new homes before you sign.
Per home. The system must sit on your property and mainly cover your own use.
A utility may refuse new systems once they add up to 1.5% of its average demand. It can ask for more.
Both use a 5% limit. Homes already connected keep their place.
6,705 kW of 10,620 kW in its March 25, 2026 filing. The figure today is higher.
The RCA opened Docket R-24-003 in September 2024 to consider raising the limit. We could not confirm the outcome, and the published regulation still says 1.5%. We found no official source for the September 2026 deadline that older guides give.
The September 2026 benchmark, $0.26 above the US average. These are modeled cash prices, not quotes we collected.
| Size (kW DC) | Cash price | Power made a year |
|---|---|---|
| 4 kW | $12,600 | 3,816 kWh |
| 6 kW | $18,900 | 5,724 kWh |
| 7.77 kW (typical) | $24,476 | 7,412 kWh |
| 9 kW | $28,350 | 8,586 kWh |
Nothing lowers the purchase price of a home system in Alaska today. The money is on your bill: the power you no longer buy, and your co-op’s credit for surplus.
Alaska has no solar rebate for homes.
Alaska has no individual income tax, so there is nothing for a solar credit to reduce.
Not for a system you own placed in service after December 31, 2025.
A borough or city may exempt home solar, but only by its own ordinance. Ask your assessor. The law does not name batteries.
Listed A to Z, not ranked. Facts from their own sites and Alaska state records, read October 13 and 14, 2026.
None of the three publishes a workmanship warranty or a warranty for roof leaks at the panel mounts. Ask for both in writing, and for the license number where it is not published.
Ask each installer to name your co-op’s surplus credit and show output month by month.
