Solar Panels Cost $5.0k-$15k in Washington County, MN | November, 2024

Minnesota Power customers may be entitled to rebates on new solar photovoltaic systems. To qualify, a system must meet all state and federal standards, be installed by a certified solar contractor, and be interconnected to the grid under a net metering contract. The incentive amount is determined through an NREL tool which considers the system's rated capacity and other design characteristics. Current rates are 56 cents/estimated kilowatt hour of production in the first year of the system's use. Minnesota Power must preapprove all incentives. Customers must therefore apply for the rebate before purchasing their system. Additional information is available from the website.

Net metering in Minnesota is set to be replaced by a Value of Solar (VOST) tariff program standardized by the Department of Commerce. No utility has implemented such a program as of 2021, though Xcel Energy is exploring retail-rate tariffs in a similar vein to VOST. VOST operates as an "inflow-outflow" program. Customers are technically billed for all electricity they generate, including excess generation (EG) sent to the grid. Rather than paying for all generated energy, however, they will only owe the cost of their "nettable energy" in that cycle. Nettable energy is equal to total power generated at the standard billed cost minus EG at a different "credit rate." As with net metering, should generation exceed consumption, the remaining credits will be applied to subsequent cycles. VOST contracts last for 20 years; credit rates are fixed for the length of the contract. "Virtual VOST" provisions exist to compensate microgrid subscribers in proportion.

New sustainable farm equipment may be eligible for special financing through Minnesota's Farm Opportunity Loan Program. The program is administered by the state Rural Finance Authority in conjunction with various funding partners. Loans can cover up to 80% of purchase and installation costs. The RFA assumes responsibility for servicing 45% of the principal up to $45,000. Interest on the RFA portion is 3%; the remaining 55% will accrue interest at the current market rate. Additional information is available from the RFA website.

Residential and commercial customers of the Dakota Electric Association may be entitled to rebates on a variety of energy-efficient improvements. Available rebate offers will vary from time to time. Current offers include rebates on large appliances, lighting, insulation/weatherization, central/room HVAC, and new solar PV or geothermal heat systems. Rebate amounts depend on the type of project and how much efficiency it will add to the property. Additional information is available from the cooperative website.

NOTE: This program appears to be defunct as of 2013. Xcel Energy has administered a Renewable Development Fund since 1999. The fund's annual budget amounts to $9 million, the result of a state-set rate per nuclear waste reservoir at the Prairie Island, Minnesota plant. Additional funding comes from a surcharge on Xcel customer bills in Minnesota and western Wisconsin. Grant programs supported by the fund usually take the form of requests for proposals (RFPs). Xcel details grant revenue and spending in an annual report submitted to the state legislature, and grant recipients produce similar supplementary reports on their projects' environmental impact. Additional information is available from the Xcel website.

Residential customers of OPU, the municipal utility for the city of Owatonna, may be eligible for rebates on energy-efficient appliances. Qualifying appliances will vary from time to time, but currently include fridge/freezers and room air conditioners certified by ENERGY STAR. To qualify for a rebate, the owner must recycle their previous appliance. OPU will cover any fees incurred from the recycling of appliances as a part of the rebate. Additional information is available from the OPU website.

Utilities in Minnesota are required to participate in Community-Based Energy Development tariff programs (C-BED) to support the construction and onboarding of new renewable energy facilities, including solar and wind farms. C-BED contracts last for 20 years. During the term, the state will pay utilities at a fixed rate for the energy they produce. The underlying goal is for utilities to more easily recoup the costs for their renewable facilities. Additional information is available from the Minnesota Public Utilities Commission website.

The Minnesota Rural Finance Authority (RFA) operates a stock financing program to aid farmers in purchasing shares of nearby wind farms or biomass energy facilities. Loans are offered by private banking partners, though the RFA sets loan terms and low interest rates for up to 45% of the principal. Qualifying applicants must not be worth more than $450,000. Additional information is available from the RFA website.

Minnesota Power manages a large-scale energy efficiency grant program. Up to $50,000 in awards may be available to businesses and farmers investing in energy efficiency improvements, including new renewable energy systems and experimental technologies. Grants depend on the applicant's need and projected energy savings. They are supplemented by rebates of $200/kW of the improvements' rated capacity. Additional information is available from the Minnesota Power website.

Minnesota homeowners making energy efficiency or accessibility improvements may be eligible for special loans from the state Housing Finance Agency (MHFA). "Fix-Up Loans" have a maximum of $15,000 in principal at market-rate interest. Applicants have direct access to MHFA lending partners and can negotiate loan terms. They may also use the contractors and builders of their choice. Lending partners differ between the 11-county Twin Cities area and the rest of the state. Additional information is available from the MHFA website.

The St. Paul Port Authority operates a PACE program in Duluth, Mankato, and certain Twin Cities suburbs and exurbs. Property owners will have access to an open market of local lenders offering competitive loans and terms for energy efficiency improvements. Effectively, funding comes from the government; repayment will therefore take the form of a tax lien senior to the property's mortgage. Residential structures are not eligible for PACE loans due to regulatory concerns from the FHFA. Fannie Mae and Freddie Mac are prohibited from acquiring a mortgage with an active PACE lien. Additional information is available from the Port Authority website.

Distributed generation and interconnection practices are standardized by the Minnesota Public Utilities Commission. Standards were last updated in 2019 and continue to be amended regularly. Unlike states which use tiers and levels to organize energy systems, Minnesota uses permit processes as benchmarks. Systems at a qualifying capacity level may be eligible for a "Fast Track" permit review. All systems must follow recognized standards such as those set by IEEE or UL. Customers may be required by their utility to carry liability insurance coverage or install additional safety features.

Xcel Energy has administered a Renewable Development Fund since 1999. The fund's annual budget amounts to $9 million, the result of a state-set rate per nuclear waste reservoir at the Prairie Island, Minnesota plant. Additional funding comes from a surcharge on Xcel customer bills in Minnesota and western Wisconsin. Funding supports incentive programs and other initiatives to adopt renewable energy. The University of Minnesota's Institute for the Environment also taps into the fund for its own research. Additional information is available from the Xcel website.

Solar*Rewards is the formal name for Xcel Energy's net metering and distributed generation tariff incentive programs nationwide. Under Minnesota law, renewable energy customers hold ownership of renewable energy credits (RECs) they generate. With a Solar*Rewards contract, the customer agrees to sell all RECs to the utility for a fixed amount of time and have a bidirectional meter installed on their system to track energy sent back to the grid. In exchange, the utility will provide fair compensation for both excess generation and credits accrued. To qualify for incentives, a new PV system must pass an engineering audit and not exceed 20 kW of DC capacity. Leased systems do not qualify for Solar*Rewards contracts. Additional information is available from the Xcel website.

Residential customers of MMU, the municipal utility for the city of Marshall, may be eligible for rebates on new energy-efficient systems and appliances. Available rebate offers will vary from time to time. Current offers include incentives for ENERGY STAR-certified fridge/freezers, washer/dryers, dishwashers, central/room HVAC, water heaters, dehumidifiers, and solar/geothermal systems (through a separate program). Customers may also receive financial assistance to certify their entire home with ENERGY STAR through an initiative targeted at new construction. Additional information is available from the MMU website.
