The short answer: Affinity Plus Federal Credit Union offers a Home Equity Solar Loan up to $100,000 and a personal solar loan up to $40,000, both with 5-, 10- or 15-year terms and no prepayment penalty. You apply with Affinity Plus directly. We supply the proposal and site plan it asks for, and you pay iSolar on our normal cash schedule. Rates depend on credit and term.

What the Affinity Plus solar loan is

Affinity Plus Federal Credit Union is a Minnesota credit union that offers loans built specifically for home solar. It's one of the lenders we work with when a homeowner wants to own the system but doesn't want to pay the full price up front.

Affinity Plus offers two solar loans:

  • A Home Equity Solar Loan, secured by your house, for larger systems and lower rates
  • A personal secured solar loan for smaller projects, for borrowers who don't want to use home equity

You apply with Affinity Plus, not through us. To us, the result works like a cash sale: you pay iSolar on our normal schedule, and the credit union lends to you.

What Affinity Plus asks you to document

The home-equity rate includes a solar discount, and getting it takes paperwork. Affinity Plus's page lists these items:

  • An installation agreement or proposal from a NABCEP-certified installer that lists the panels, inverters and other components. Our master electrician, John Ihle, holds a NABCEP credential.
  • A solar site plan showing the address and where the system will go
  • A complete utility bill from the last six months
  • An Xcel Solar*Rewards acknowledgement letter, when it applies

As of October 2026, the page also still asks for tax documents showing you can use the federal residential solar credit. That credit isn't available for systems placed in service after December 31, 2025. Ask your loan officer how they handle this requirement now. We can't speak for the credit union's underwriting.

We provide the proposal, equipment list and site plan as part of every quote. If you're enrolling in Solar*Rewards, we file the application and pass along Xcel's letter when it arrives.

How it works with iSolar

  1. Get a written proposal. We design your system and give you a cash price with an itemized equipment list, production estimate and site plan. Start with a free quote.
  2. Become a member and apply. Affinity Plus membership is based on where you live, work or study, or a household connection. Apply online and a mortgage loan officer follows up to complete it.
  3. Send Affinity Plus our documents. Forward the proposal, site plan and utility bill. If you need anything else from us, just ask.
  4. Line up timing. We'll schedule your contract and the 5% deposit ($1,200 minimum) around your loan approval so you aren't waiting on one or the other.
  5. Close your loan. Home-equity loans close like a small mortgage, with closing costs paid by you.
  6. Permits, install and PTO. We handle permits, interconnection and the 1–2 day install. You pay the balance at the milestones in your contract, the same as any cash purchase.

Things to compare before you choose it

  • Your home is collateral on the home-equity version. That's how you get the lower rate, but it's still a lien. If you're refinancing or selling soon, talk to your loan officer first.
  • Closing costs add to the cost of borrowing. Get the estimate in writing and include it in your total.
  • No dealer fee is involved. You're borrowing from a credit union and paying us directly, so the price you finance is our cash price. Our post on dealer fees in solar loans explains why that matters.
  • Federal credit math is gone. Some older solar loans assumed a 30% tax-credit paydown in year two. That doesn't apply to a home system installed now, so budget for the full payment. See our 2026 tax credit explainer.

Who it's best for, and who it isn't

Best for

  • Minnesota homeowners with equity who want a fixed rate and a term of up to 15 years
  • Borrowers who'd rather work with a local credit union than a national solar lender
  • Larger systems, or solar plus a battery, up to $100,000 on the home-equity option. Confirm with Affinity Plus what it will finance beyond the panels.

Not ideal for

  • Homeowners who don't want a second lien on the house
  • Anyone who needs the fastest decision possible, since home-equity loans take longer to close than point-of-sale loans like One Ethos
  • Borrowers who may not qualify for membership. Check eligibility first.

Next step

Get your proposal first. It's the document Affinity Plus needs, and it shows the exact amount to borrow. Request a free quote, or estimate your payback with the solar payback calculator before you call the credit union.

Good questions

Frequently asked.

Do I have to be an Affinity Plus member to get a solar loan?

Yes. You need to be eligible for membership, which Affinity Plus bases on where you live, work or study, or a household connection to an existing member. Check eligibility on its membership page before you apply.

What interest rate does the Affinity Plus solar loan have?

As of October 2026, Affinity Plus advertises home-equity solar loans starting at 5.490% APR and personal solar loans starting at 7.99% APR. Your actual rate depends on credit, term and loan-to-value. Confirm the current rate with Affinity Plus.

Does Affinity Plus charge a dealer fee on solar loans?

You borrow directly from the credit union and pay us our cash price, so there's no dealer fee built into your system price. Home-equity loans do have closing costs, which you pay. Ask for the closing cost estimate in writing.

Can I pay off an Affinity Plus solar loan early?

Yes. Affinity Plus lists no prepayment penalty on its solar loans, so you can pay extra or pay the loan off at any time.

Does iSolar qualify as a NABCEP-certified installer for the Affinity Plus discount?

Our master electrician, John Ihle, holds a NABCEP credential, and we provide the itemized proposal and site plan the credit union asks for. Affinity Plus decides whether your documents qualify for its rate discount.

Can I finance a battery with an Affinity Plus solar loan?

Affinity Plus's solar loan pages describe financing for the solar system and don't mention batteries specifically. Ask your loan officer before you apply. If a battery isn't covered, we can quote it separately.
