Solar Incentives in Alaska
Alaska homeowners considering solar in 2026 have access to a limited but meaningful set of state-level programs. Under rules established by the Regulatory Commission of Alaska effective June 2010, every economically regulated electric utility in the state is required to offer net metering to eligible customer-generators, including solar PV systems up to 25 kW per premises. Monthly billing is netted at retail rates, but any net excess generation is credited in dollars at each utility's quarterly-updated non-firm power rate — meaning the export compensation rate varies by utility and changes over time. Alaska statute also provides a local-option property tax exemption for residential renewable energy systems, including solar; however, this is an enabling law only, and individual municipalities must adopt their own ordinances to activate it, so coverage varies significantly by location. The Alaska Energy Authority's Renewable Energy Fund grant program and Power Project Fund loan program are also active, though both primarily target utilities, local governments, and independent power producers rather than individual homeowners.
On the federal side, the residential Clean Energy Credit under Internal Revenue Code §25D — commonly described as the 30% solar tax credit — expired for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act (Pub. L. 119-21). Homeowners installing solar in 2026 do not qualify for that credit, which meaningfully extends payback periods compared to installations completed in prior years.
Alaska's residential electricity rate averaged approximately 27.17 cents per kilowatt-hour as of March 2026, one of the higher rates in the country, which improves the economic case for self-generation. However, without the federal credit, and given that property tax exemption availability depends entirely on local ordinance adoption, prospective buyers should carefully verify which incentives apply in their specific municipality before making financial projections.
Figures here are verified as of June 2026 against official sources; programs change with each legislative session and utility rate case, and the Regulatory Commission of Alaska and Alaska Energy Authority websites are the authoritative sources for current program terms.
Federal credit update. The federal residential Clean Energy Credit (the 30% “solar tax credit” under §25D) expired for systems placed in service after December 31, 2025. New 2026 residential installs do not qualify; a 2025 install can still be claimed on a 2025 return (IRS Form 5695). What this means for 2026 →

Alaska Net Metering Standards
Regulatory Commission of Alaska rules (effective June 16, 2010) require every economically regulated electric utility to offer a net metering program and to interconnect eligible customer generation systems, including solar PV, with a total nameplate capacity of no more than 25 kW per consumer premises. Billing is netted monthly: if the customer used more than they generated they pay the normal tariff rate on the net amount, and if they exported more than they used the excess kWh are credited in dollars at the utility's non-firm power (avoided-cost) rate; credits carry forward to later bills and never expire. A utility may refuse new interconnections once total net-metered capacity reaches 1.5% of its average retail demand (it may ask the RCA to use a higher limit), and the rules do not apply to very small independent systems (under 5,000,000 kWh of annual retail sales) or to systems already nearly 100% renewable.
| Amount | Monthly netting at retail rates; net excess generation credited in dollars at the utility's quarterly-updated non-firm power rate (varies by utility tariff); credits carry forward indefinitely. System cap 25 kW per premises; aggregate cap 1.5% of the utility's average retail demand unless the utility adopts a higher limit. |
|---|---|
| Who qualifies | Retail customers of RCA economically regulated electric utilities who own or lease an on-premises generation system of up to 25 kW using solar PV, solar thermal, wind, biomass, hydro, or other listed renewable sources, used primarily to offset the customer's own electricity needs, with an inverter. |

Local Option Property Tax Exemption for Residential Renewable Energy Systems
Alaska statute lets any municipality, by ordinance, classify and exempt from property taxation 'a residential renewable energy system that is used to develop means of energy production using energy sources other than fossil or nuclear fuel, including windmills and water and solar energy devices located in the municipality.' This is an enabling law only: whether a solar exemption is actually available, and its terms, depends entirely on whether the homeowner's city or borough has adopted such an ordinance. Homeowners should check with their local assessor.
| Amount | Full or partial exemption as set by local ordinance; varies by municipality (many municipalities have not adopted one). |
|---|---|
| Who qualifies | Owners of residential renewable energy systems (including solar) located in a municipality that has adopted the optional exemption by ordinance. |
| Administered by | Individual Alaska municipalities (cities and boroughs), under a statewide enabling statute |

Renewable Energy Fund (REF) Grant Program
The Renewable Energy Fund, established by the Legislature in 2008 and extended in perpetuity by House Bill 62 in 2023, provides grant funding for competitively selected renewable energy projects (including solar) that produce cost-effective heat and power for Alaskans. It is managed by the Alaska Energy Authority with a nine-member advisory committee; recommended projects are funded through legislative capital appropriations. Since inception, 296 grants totaling nearly $333 million have been awarded and over 110 operating projects built. This is a project-development grant program for utilities, communities, and project sponsors selected through periodic application rounds, not a rebate paid to individual homeowners; the Round 18 application period closed September 12, 2025, with recommendations going to the Legislature for the FY2027 capital budget.
| Amount | Grant amounts vary by project and legislative appropriation; Rounds 13-17 funded 67 projects with $53.6 million in appropriations; program total nearly $333 million across 296 grants. |
|---|---|
| Who qualifies | Qualifying renewable energy projects selected competitively through AEA requests for applications in periodic funding rounds; eligibility details published with each round's RFA. |

Power Project Fund (PPF) Loan Program
The Power Project Fund provides loans through the Alaska Energy Authority to local utilities, local governments, and independent power producers for the development, expansion, or upgrade of electric power facilities, including renewable generation, distribution, transmission, efficiency and conservation, bulk fuel storage, and waste energy projects. Loan terms are tied to the productive life of the project up to a maximum of 50 years, with interest rates ranging from zero up to the tax-exempt municipal bond rate (the average weekly municipal bond yield for the 12 months before application), adjustable downward to improve project feasibility. Loan requests over $5 million require legislative authorization, and application fees scale from $200 (loans up to $100,000) to $5,000 (loans over $1 million). This is institutional project financing, not a homeowner loan.
| Amount | Loan size project-dependent; >$5 million requires legislative authorization to apply; terms up to 50 years; interest between 0% and the tax-exempt municipal bond rate; application fees $200-$5,000 by loan size. |
|---|---|
| Who qualifies | Local utilities, local governments, and independent power producers developing, expanding, or upgrading electric power facilities in Alaska. |
