Mosaic Solar Loan: What Existing Borrowers Need to Know
A Mosaic solar loan does not disappear just because the company stopped writing new ones. Solar Servicing says Mosaic’s CHOICE and PLUS products have not been available since June 6, 2025.[1] If you already have a Mosaic balance, an old quote, or a contract built around a tax-credit prepayment, what matters now is what your own paperwork says, not what the company used to advertise.
ChooseMyPower is Ranked by your bill, not our commission. We don’t sell solar loans and we aren’t a nationwide lender marketplace. What we can do is show you which documents to pull and which questions to ask: your loan agreement, the cash price of your system, the amount actually financed, and your electricity bill. Read the contract before you read the sales pitch. A low starting payment can depend on a bigger payment later, and a low rate can sit next to a higher financed price. In Texas, a solar loan also doesn’t remove your need to check the Electricity Facts Label, TDU delivery charges, and whatever retail electricity plan covers the grid power you still use.
What Happened to Solar Mosaic
Solar Servicing says it completed the acquisition of Solar Mosaic’s loan-servicing operations on September 22, 2025, following Mosaic’s court-approved Chapter 11 plan.[2] That lines up with an earlier change for new customers: Mosaic’s CHOICE and PLUS loan products stopped being offered on June 6, 2025.[1] An old web page or a saved sales sheet from before that date is not a current financing menu.
None of that changes what an existing loan is. Solar Servicing’s borrower FAQ says servicing continues for most customers, with no change to payment terms or schedules.[2] The obligation described in your agreement is still the obligation. It’s just serviced by a different company now.
What Existing Mosaic Borrowers Should Do Now
You don’t need to guess at any of this. Work through it using your own documents.
- Find your promissory note and most recent statement. That’s where your actual payment, balance, interest rate, and prepayment terms live, not a sales sheet or an old marketing page.
- Confirm who is servicing your loan. Solar Servicing says borrowers should continue making payments as their agreements require unless told otherwise.[2]
- Check your payment amount and schedule against what you were told. Solar Servicing’s FAQ says most customers keep the same payment options and remain obligated under the terms and schedule already in their agreement.[2]
- If you have a CHOICE loan, find your month-18 prepayment clause. The rule and the date are explained below, in the Teaser Test section.
- Keep copies of everything. Save your agreement, your payment history, and any written message about a payment change.
- Request a written payoff amount before acting on an early payoff or a home sale. Mosaic loans have no prepayment penalties, but the balance and timing are specific to your account.[1] If you expect to sell before the loan is paid off, review your contract’s payoff, transfer, lien, and title language rather than assuming a buyer can simply take over the loan.
For a new system, ask each lender for its own cash-price comparison and loan disclosure. Do not assume a different loan has the same payment-change rule as an old Mosaic contract. The table below shows where to look depending on your situation.
| Your situation | Start with this document | Question to answer |
|---|---|---|
| You are paying a Mosaic loan | Promissory note and current statement | What payment, balance, interest rate, and prepayment terms apply to your contract? |
| You have an old installer quote | Cash proposal, financing disclosure, installation contract | Does the financed price exceed the cash price, and why? |
| You are comparing a new loan | Cash proposal and lender disclosure | What are you paying for the system before financing is added? |
| You may move before payoff | Loan agreement and title documents | What does your contract require for payoff, transfer, lien, or other title steps? |
Run the Teaser Test Before You Trust the Starting Payment
The Teaser Test is simple: compare the sales-rep payment with the payment your signed loan requires if the expected lump-sum prepayment never arrives. If they differ, the lower number is not the whole story.
For Mosaic CHOICE loans, Solar Servicing says a voluntary prepayment equal to 30% by the end of month 18 keeps the monthly payment the same. Paying less means the monthly payment goes up.[1]
The seller may describe that voluntary payment as money from a federal solar tax credit. That explanation needs a date check. The IRS says the Residential Clean Energy Credit was 30% for qualified property installed through December 31, 2025, and it is not available for property placed in service after that date.[3] The IRS also says the credit is nonrefundable.[3]
For an existing borrower, what matters is what the signed note says about the prepayment amount and timing, not whether a tax credit sounds plausible in a sales conversation. Whether you actually qualified for a historical tax credit is a tax question for a qualified tax professional, not a promise an installer can make at the kitchen table.
Use the Teaser Test this way: find the clause about a voluntary prepayment, target balance, re-amortization, or month 18. Write down the payment before and after that window. Keep the tax question separate from the loan question.
The Consumer Financial Protection Bureau warns that solar-loan sales materials have sometimes treated a presumed tax credit as if every consumer will receive it, even though tax treatment depends on the consumer’s own federal tax liability.[4]
Receipt to keep: the page showing the month-18 prepayment amount, the payment before that deadline, and the payment after it. That is the page worth reading twice.
The Dealer-Fee Test: Compare the Cash Price With the Financed Price
A low APR does not automatically mean a low-cost loan. Dealer fees are one reason. The CFPB says some solar-specific lenders include markups and fees that can raise the loan principal by 30% or more above the cash price. The fees are often built into principal rather than shown as a separate line item.[4]
That’s an industry-wide finding, not a claim that every Mosaic contract or every solar contract carries the same fee. Instead of asking whether the rate looks low, ask how much more you are financing than the cash price of the installed system.
Ask the installer for a cash proposal and keep it beside the loan disclosure. Then ask the lender and installer to explain every difference between the cash price, the contract price, the amount financed, and the total of scheduled payments. A difference is not automatically a dealer fee. It may reflect taxes, add-ons, or other terms. But a clear written explanation is the minimum you should expect.
| Compare this | Against this | What it exposes |
|---|---|---|
| Cash price for the same system | Price in the installation contract | Whether the financed sale starts above the cash sale |
| Contract price | Amount financed in the loan disclosure | What the lender is funding |
| Amount financed | Total of scheduled payments | The loan cost over its stated term |
| Starting payment | Payment after the month-18 window | Whether the loan assumes a large prepayment |
This is bill literacy, not a promise of savings. You need the full set of documents to compare a low rate with a low starting balance.
Use the EFL Decoder Before You Call Solar a Bill Replacement
Solar is one part of an energy-cost picture. It is not a substitute for reading the retail electricity plan in a deregulated Texas area. Your electric bill can still include grid power, retail plan charges, and TDU delivery charges. The amount of power you buy from the grid can change. The need to read the plan terms does not.
That is where the EFL Decoder matters. We read the EFL so you don’t have to. The guide to reading a Texas Electricity Facts Label shows where to find the energy charge, base charges, usage credits, TDU delivery charges, and contract term. The Texas electricity-rate guide explains why the advertised cents-per-kWh number is not the whole bill.
Do not combine everything into one claim such as “my solar payment replaces my electric bill.” Keep the loan payment, the retail plan bill, and any export-credit terms in separate columns. That makes a sales claim testable.
The Real-Bill Ranking: The Honest Electricity Check
ChooseMyPower’s fully built comparison experience currently covers deregulated states such as Texas, our flagship market, and is expanding to more. It is not a nationwide solar-lender scorecard, and we don’t pretend otherwise. The dedicated solar-finance comparison, the Real Payback Ranking, is not live yet.
For residents of a deregulated area such as Texas, the Real-Bill Ranking sorts available electricity plans by stated usage rather than a headline rate or provider commission. It is useful whether you have panels, are considering panels, or need to renew your plan.
One practical next step: Compare Texas electricity plans with the Real-Bill Ranking at the usage level shown on your bill. Keep that plan comparison separate from your solar-loan comparison.
That separation is the point. A loan document should prove the cost of financing. An Electricity Facts Label should prove the cost structure of the retail plan. Neither document proves the other.
FAQ: Mosaic Solar Loan
What happened to Solar Mosaic?
Solar Mosaic went through a court-approved Chapter 11 plan, and Solar Servicing says it completed the acquisition of its loan-servicing operations on September 22, 2025.[2] Mosaic’s CHOICE and PLUS loan products also stopped being offered to new customers on June 6, 2025.[1]
Is Mosaic offering new solar loans?
No. Solar Servicing says Mosaic CHOICE and PLUS loan products have not been available since June 6, 2025.[1] If you are looking at a new installation, ask a current lender for its own cash-price comparison and disclosure documents.
Who services an existing Mosaic solar loan?
Solar Servicing says it acquired Mosaic’s loan-servicing operations in September 2025. Its borrower FAQ says that, for most customers, servicing continues with no changes to payment terms or schedules.[2]
How do I make a payment on my Mosaic solar loan?
Solar Servicing’s borrower FAQ says most customers keep the same payment options and should continue paying as their agreement requires unless told otherwise.[2] If you are unsure how or where to pay, start with Solar Servicing’s borrower FAQ page and your most recent statement.
What happens if I do not make the 30% payment by month 18?
For a Mosaic CHOICE loan, the servicing page says that making less than the 30% voluntary prepayment before the end of month 18 causes the monthly payment to go up.[1] Your agreement controls the exact amount and date.
Does the federal solar tax credit still fund a Mosaic prepayment?
Do not assume it does. The IRS says the residential credit is not available for property placed in service after December 31, 2025.[3] Existing borrowers with older installations should use their own tax records and get qualified tax guidance rather than rely on a generic solar sales claim.
Can I pay a Mosaic loan off early?
Solar Servicing says Mosaic loans have no prepayment penalties.[1] Ask for a written payoff amount for your account, since the balance and timing are individual to the loan.
Bottom Line
A Mosaic solar loan deserves a document review, not a headline-rate review. Run the Teaser Test on the month-18 prepayment. Run the dealer-fee test against the cash price. Then use the EFL Decoder and the Real-Bill Ranking for the Texas electricity plan that continues alongside the loan.
That is the ChooseMyPower standard: Ranked by your bill, not our commission.
