In Alaska the calendar decides more than the sun does. Power is costly, but the bill is settled each month, so summer surplus earns only your co-op’s lower credit and never reaches the winter bill. In our example a typical owned system takes about 28 years to pay back at Chugach’s credit, longer than panels usually last, and about 21 at Golden Valley’s.
Typical payback, Chugach creditAbout 28 years
Chugach or Golden Valley creditAbout 21 to 28 years
Typical owned 7.77 kW Alaska system at $24,476 cash (EcoGen Solar Cost Index, September 2026), no incentives, EIA average price, Chugach’s surplus credit. Our assumptions: 40% used at home as it is made, $233 a year in owner costs. At Chugach’s credit, payback takes longer than the 25 years panels usually last. See the math.
- Co-op: ask for this quarter’s surplus credit in writing.
- Size: match your summer months, not your roof.
- Use pattern: a home that uses power all year keeps more of its solar.
2026 rules: new home systems get no 30% federal homeowner credit (IRS). Alaska has no state rebate and no state income tax to credit against. Under the state net metering rules, each month’s extra power earns your co-op’s lower credit.
How we checked this guide
Rules come from the Alaska Administrative Code and the co-ops’ tariffs and program pages; prices from the U.S. EIA and the EcoGen Solar Cost Index. Assumed numbers are labelled.
The writer and checker shown above are EcoGen staff. EcoGen is paid when homeowners request quotes, which is explained beside the quote form. Read our editorial standards.
Where an Alaska home lands: five checks
Alaska pairs some of the costliest power in the country, 26.85¢ per kWh on average, with the weakest sun we record: 954 kWh a year from each kW of panels. What tips the result is how much solar you use in the month it is made. Read each row across.
Your co-op
Worth a closer look
Golden Valley serves you and credits surplus at 13.726 cents per kWh.
Pause and check
Chugach’s tariff credits surplus at 6.831 cents per kWh, about a quarter of the average price.
Check next: the co-op’s surplus credit for this quarter, with its date.
Size against summer use
Worth a closer look
The system makes about what your home uses in a June or July month.
Pause and check
The quote fills the roof, so each summer month’s extra kWh earn the low credit.
Check next: your summer bills next to the quote’s month-by-month output.
When you use power
Worth a closer look
Your home uses plenty of power in the bright months too.
Pause and check
Most of your use falls in the dark months, when the panels make little.
Check next: twelve months of bills, and which months are the big ones.
Roof and snow
Worth a closer look
A south-facing, unshaded roof steep enough to shed snow.
Pause and check
A shallow roof that holds snow, or trees that shade the low summer sun.
Check next: a shade report and an output estimate for each month.
Price and time in home
Worth a closer look
A cash price near the Index’s $3.15 per watt, and you plan to stay 25 years or more.
Pause and check
A dealer fee in the loan, or a likely move well before payback.
Check next: cash and financed prices side by side, with APR and fees.
One Alaska system at two co-op credits
Simple payback is the years your savings take to cover what you paid: net cost divided by yearly savings. A kWh (kilowatt-hour) is the unit on your power bill. An export credit is what you get for each kWh your panels send to the grid. In Alaska it is a dollar credit at your co-op’s avoided cost rate: roughly what the co-op would pay to make or buy that power itself.

Inputs: the EcoGen Solar Cost Index typical Alaska system (7.77 kW, $24,476 cash, September 2026; 954 kWh per kW a year). Alaska’s Index price is modeled from nearby states. No rebate is counted; Alaska has none. Export credit: Chugach’s tariff rate, effective July 1, 2026. The EIA average includes fixed charges, and each co-op sets its own price, so your avoided rate may differ. Two inputs are our assumptions: 40% of the solar power used at home as it is made and 60% sent to the grid, and $233 a year in owner costs ($30 per kW, including a reserve for a new inverter). The cost page’s about 12.3 years values every kWh at the full price and counts no owner costs.
Now move the same house to Fairbanks, where Golden Valley pays about twice Chugach’s rate for surplus.
| Scenario | Export credit | Export value | Yearly savings | Simple payback |
|---|---|---|---|---|
| Chugach credit | $0.06831/kWh | $304 | $867 | about 28.2 years |
| Golden Valley credit | $0.13726/kWh | $610 | $1,173 | about 20.9 years |
About seven years ride on which co-op bills you. Neither credit comes near the price of power, so the bigger lever is the 40% share: use more solar in the month it is made, and payback shortens at any co-op.

Why June’s surplus cannot pay January’s bill
In Alaska, panels and homes peak in opposite seasons. Summer days pile up power when homes need the least; in midwinter the panels make almost nothing.
Summer power cannot wait for winter: Alaska settles the account once a month. Solar that covers your use in that month saves the full price. Whatever is left at month’s end becomes a dollar credit at the co-op’s lower rate, and the next month starts from zero.
Used at home: 2,965 kWh. Each one replaces power you would have bought, so it saves the full variable rate ($0.2685 here).
Sent to the grid: 4,447 kWh. These earn whatever your utility pays for exports ($0.06831 here). That can be far less.
The dollar credits do not expire and lower later bills. What is lost is the gap between the full price and the surplus rate. Systems can be up to 25 kW, but with monthly settling a big system mostly makes more cheap surplus.
Find out which co-op serves your address
Chugach, Matanuska, Golden Valley or Homer Electric sets your surplus credit. Ask each installer which one, and which rate, they modeled.

What each big co-op pays for your surplus
Member-owned co-ops serve most Alaska homes; four serve about 78% of the state’s home electric customers. Same state rules, different surplus price, reset every quarter.
Co-op | Share of Alaska homes (EIA, 2024) | Credit for monthly surplus | Application fee |
|---|---|---|---|
Chugach Electric (Anchorage area) | about 1 in 3 | 6.831 cents per kWh in its tariff, effective July 1, 2026 | $270 |
Matanuska Electric (Mat-Su, Eagle River) | about 22% | Reset each quarter; ask for this quarter’s rate | None |
Golden Valley Electric (Fairbanks, Interior) | about 14% | 13.726 cents per kWh, September 1 to November 30, 2026 | $65 |
Homer Electric (Kenai Peninsula) | about 10% | Reset each quarter; ask for this quarter’s rate | Ask Homer Electric |
Chugach’s rate follows its quarterly cost-of-power update, so a newer figure may apply when you sign. Golden Valley’s next reset is December 1, 2026. Each co-op also sets its own price per kWh, so the state average in our example is not your rate.
Limits, open questions and the money that is not there
A utility may turn away new net metered homes once their systems add up to 1.5% of its average demand, unless it takes a higher limit. Chugach’s is 5%, or 10,620 kW; its March filing showed about 63% of that in use.
The state regulator opened Docket R-24-003 in September 2024 on how many solar homes a utility must accept. Its outcome is unconfirmed, and we found no official source for the September 2026 deadline older guides give. Ask your co-op whether systems connected now keep today’s terms.
The Alaska Energy Authority’s $750,000 net metering pilot, open until June 30, 2028 at the latest, pays utilities that join, not homeowners. A borough or city may exempt home solar from property tax (AS 29.45.050(b)(1)(E)), but only by its own ordinance. We could not confirm lease or PPA offers for Alaska homes, so this page covers owned systems.
What to get in writing before an Alaska contract
A yearly output total hides the Alaska problem. Ask for these.
- Co-op and credit date. Your co-op and the surplus credit the quote assumed, with its date.
- Month-by-month output. Twelve monthly kWh figures, not one yearly total.
- Size against your bills. Output in your sunniest months next to your use in those months.
- Application fee. Who pays it: $270 at Chugach, $65 at Golden Valley, none at Matanuska.
- Room to connect. The co-op’s written word that it still takes new net metered homes.
- Cash and financed prices. Both totals side by side, with any dealer fee shown, and no federal tax credit counted.
Compare Alaska solar quotes
Ask each installer to name your co-op’s surplus credit and show output month by month. Enter your ZIP code to request quotes from solar providers that serve your area.
How EcoGen is paid
EcoGen America does not sell or install solar. When you request quotes, we pass your request to solar providers serving your area, and they pay us for the introduction. Providers can include installers, solar marketplaces and lead exchanges, and more than one may contact you. You never pay us.

Alaska solar questions
Are solar panels worth it in Alaska?
They can be at some co-ops, for a home that stays put and uses power all year. In our example a typical owned system takes about 28 years to pay back at Chugach’s surplus credit, longer than panels usually last, and about 21 at Golden Valley’s. High power prices help; weak winter sun and monthly settling hold it back.
How does net metering work in Alaska?
State rules (3 AAC 50.900 to 3 AAC 50.949) cover utilities the state regulates, for systems up to 25 kW. Each month, your solar is set against your use and saves the full price. Extra power becomes a dollar credit at your co-op’s lower rate. Credits lower later bills and do not expire.
What does my Alaska co-op pay for surplus solar?
It depends on the co-op. Golden Valley credits 13.726 cents per kWh from September 1 to November 30, 2026. Chugach’s tariff lists 6.831 cents per kWh, effective July 1, 2026. Matanuska and Homer Electric reset theirs each quarter and posted no current figure, so ask for it in writing.
Do solar panels work through an Alaska winter?
They work, but for several dark months they make very little, and snow on the panels cuts output further. Because Alaska settles each month on its own, power made in June cannot be carried as kWh into January. It becomes a dollar credit at the lower rate.
Are Alaska net metering rules about to change?
Possibly. The state regulator opened Docket R-24-003 in September 2024 on how many solar homes a utility must accept. We could not confirm its outcome, and we found no official source for the September 2026 deadline older guides give. Ask your co-op in writing whether systems connected now keep today’s terms.
Does Alaska have a solar tax credit or rebate?
No. Alaska has no state income tax, so there is no state solar credit, and no state rebate for homes. The federal homeowner credit ended for systems installed after December 31, 2025. A borough or city may exempt home solar from property tax, but only by its own ordinance. Ask your assessor.
Sources, method and corrections
The example uses the EcoGen Solar Cost Index typical Alaska system (September 2026), the EIA average price, and two co-op surplus credits: Chugach’s and Golden Valley’s. Our assumptions, not measured values: 40% of the solar power used at home as it is made and 60% sent to the grid, and $233 a year in owner costs ($30 per kW, including a reserve for a new inverter). The 40/60 split is a planning assumption based on home-use research, not a measured Alaska average. With Alaska’s summer-heavy output, many homes may send out more, which lengthens payback. Simple payback uses flat first-year values. The calculator runs in your browser and sends nothing.
Updated October 2026: 40% home use and 60% exports, and owner costs of $30 per kW a year. Earlier: September 2026 Cost Index figures, this quarter’s Golden Valley credit, Chugach’s tariff rate, EIA’s full customer count, and no unconfirmed rule deadline.
