Here is everything you need to know about their rates, loan products, and how they compare to Mosaic, GoodLeap, and other solar lenders.
Quick Answer
Concert Finance is a specialty solar lender offering 25-year loans from $10,001 to $135,000 with zero dealer fees. APR ranges from 7.79% (Tier 1, 760+ FICO) to 9.79% (Tier 4, 660+ FICO) with a 0.50% ACH discount. They power the Propel Transitional Ownership program and integrate with Artemis and Solargraf design platforms. Unlike Mosaic or GoodLeap, Concert Finance does not charge hidden dealer fees, making their true cost of borrowing significantly lower despite higher advertised APRs.
Concert Finance is a specialty solar lender that operates exclusively through approved installer partners. Unlike household-name lenders like Mosaic or GoodLeap that advertise directly to consumers, Concert Finance takes a B2B approach: they build financing tools for solar installers and let the installer manage the customer relationship.
This matters because Concert Finance's business model eliminates the dealer fee structure that inflates loan balances at other lenders. When Mosaic or GoodLeap advertise “1.99% APR” solar loans, they are typically charging the installer 20-35% of the project cost as a dealer fee. That fee gets baked into your loan principal, meaning you pay interest on a $39,000 balance for a $30,000 system. Concert Finance simply does not do this.
Concert Finance's primary claim to innovation is the Propel Transitional Ownership program, which pairs a Prepaid Energy Services Agreement (ESA) with a 25-year loan. This hybrid structure allows a third-party investor to hold the system for 5 years, claim the Section 48E commercial investment tax credit, and then transfer ownership to the homeowner automatically.
Concert Finance integrates directly with Artemis and Solargraf, two leading solar design platforms. This means when your installer designs a system and generates a proposal, Concert Finance pricing is calculated automatically based on the system specifications and your credit profile. There is no separate financing application portal; everything flows through the design tool.
Concert Finance offers two distinct financing products. Understanding the difference is critical because they serve very different homeowner situations.
A traditional 25-year amortizing solar loan. You own the system from day one. Best for homeowners who want straightforward financing with transparent pricing.
A Prepaid ESA + 25-year loan hybrid. A third-party investor captures the 30% Section 48E ITC during years 1-5, then transfers ownership to you automatically. Best for homeowners who want the ITC benefit that Section 25D no longer provides.
The critical distinction between these two products is the ITC. When Section 25D expired at the end of 2025, homeowners who purchase solar with cash or a standard loan receive zero federal tax credit. But Section 48E, the commercial investment tax credit, is still active. Propel uses a third-party ownership structure that qualifies for 48E, capturing 30% (base) plus potential bonuses of 10% for domestic content (FEOC) and 10% for energy community designation, totaling up to 50% in credits that get passed through as lower monthly payments.
For most homeowners in 2026, Propel is the better product unless you specifically want immediate ownership and are comfortable forgoing the ITC entirely. The 5-year managed period is the trade-off for capturing a credit that is otherwise unavailable to residential buyers.
Concert Finance uses a “results-based pricing” model, which means your interest rate is determined entirely by your credit score. There are no points to buy down, no origination fees to pay, and no dealer fees to inflate the balance. What you see is what you get.
| Credit Tier | FICO Range | Standard APR | ACH APR | Est. Monthly ($30K) |
|---|---|---|---|---|
| Tier 1 (Excellent) | 760+ | 7.79% | 7.29% | ~$230 |
| Tier 2 (Very Good) | 720-759 | 8.49% | 7.99% | ~$245 |
| Tier 3 (Good) | 690-719 | 8.99% | 8.49% | ~$255 |
| Tier 4 (Fair) | 660-689 | 9.79% | 9.29% | ~$270 |
Every Concert Finance borrower can reduce their APR by 0.50% by enrolling in automatic ACH payments. On a $30,000 loan over 25 years, this saves approximately $3,200 in total interest. There is no penalty for switching off ACH later, though you lose the discount going forward.
Concert Finance loans include three scheduled re-amortization dates during the 25-year term. At each re-amortization point, the remaining loan balance is recalculated based on what you actually owe. If you have made additional principal payments above your scheduled amount, the re-amortization will lower your monthly payment for the remainder of the loan.
This is valuable because most solar loans lack this feature. With a standard amortizing loan, extra payments shorten your loan term but do not reduce your monthly payment. Concert Finance's approach gives you the flexibility to pay more when you can and benefit from lower payments later.
For example, if you receive a bonus or inheritance and pay $10,000 extra toward principal in year 3, the first re-amortization date will recalculate your payment based on the lower remaining balance. Your monthly payment drops, but you still pay off the loan within the original 25-year term unless you continue making extra payments.
Comparing solar lenders on advertised APR alone is a mistake. The real cost of a solar loan depends on three factors: APR, dealer fees, and term length. Dealer fees are the hidden tax that most solar lenders charge, and understanding them is essential to choosing the right financing.
When a lender advertises a “1.99% APR” solar loan, they are almost certainly charging the installer a dealer fee of 25-35%. The installer adds this to your system price. On a $30,000 system, a 25% dealer fee means your actual loan balance is $37,500. You pay 1.99% interest on $37,500 for 25 years. The effective cost of borrowing is dramatically higher than 1.99%.
| Lender | APR Range | Dealer Fees | Loan Range | Min FICO | TPO Option |
|---|---|---|---|---|---|
| Concert Finance | 7.79-9.79% | 0% | $10K-$135K | 660 | Propel |
| Mosaic | 4.99-8.99% | 15-30% | $5K-$150K | 600 | None |
| GoodLeap | 4.49-9.99% | 20-35% | $5K-$150K | 600 | None |
| Sunlight Financial | 3.99-8.99% | 15-25% | $10K-$100K | 650 | None |
| Dividend Finance | 5.99-9.99% | 10-25% | $5K-$100K | 620 | None |
Mosaic is the largest residential solar lender in the US and offers loans in 45+ states. Their advertised rates start at 4.99% APR, which is significantly lower than Concert Finance's 7.79%. However, Mosaic charges dealer fees of 15-30% depending on the rate tier. On a $30,000 system, a 25% dealer fee adds $7,500 to your loan balance, making your actual borrowing $37,500 at 4.99% for 25 years. The total interest paid is approximately $26,200 on the inflated balance. With Concert Finance at 7.79% on a true $30,000 balance, total interest is approximately $24,800. Concert Finance is cheaper despite the higher APR.
GoodLeap is the second-largest solar lender and charges even higher dealer fees than Mosaic, typically 20-35%. Their lowest rates (4.49%) come with the highest dealer fees (35%), which means a $30,000 system becomes a $40,500 loan. At 4.49% over 25 years, you pay approximately $28,700 in interest. With Concert Finance at 7.79% on $30,000, you pay approximately $24,800. GoodLeap offers more flexible term lengths (12-25 years) and works in more states, but the true cost of borrowing is almost always higher.
Sunlight Financial offers some of the lowest advertised rates in solar lending (starting at 3.99%), but with dealer fees in the 15-25% range. Their maximum loan amount is $100,000, compared to Concert Finance's $135,000. Sunlight Financial experienced well-publicized financial difficulties in 2023 and was acquired by a private equity firm. Service continuity and warranty backing are concerns some installers have raised. Concert Finance is a newer entrant but has not had similar stability issues.
Dividend Finance occupies a middle position with APRs from 5.99-9.99% and dealer fees of 10-25%. Their 10% dealer fee tier brings them closer to Concert Finance's true cost model, though a 10% fee on $30,000 still adds $3,000 to the loan balance. Dividend Finance has a lower minimum FICO of 620 versus Concert Finance's 660, making them more accessible for homeowners with fair credit. If your FICO is between 620-659, Dividend is an option where Concert Finance is not.

One of Concert Finance's strongest features is its deep integration with solar design platforms. When your NuWatt installer designs a system using Artemis or Solargraf, Concert Finance pricing is generated automatically as part of the proposal. There is no separate financing application, no manual data entry, and no delay between system design and financing approval.
This integration matters because it eliminates the friction that causes projects to stall. With traditional solar lenders, the installer designs a system, presents it to you, and then you apply for financing separately. If the financing terms differ from what the installer quoted, the project needs to be re-scoped. Concert Finance's platform integration ensures that the price you see in the proposal is the price you get.
Artemis is a proposal management tool that handles system design, pricing, and contract generation. Concert Finance integrates at the pricing layer, meaning the financing terms are calculated within Artemis based on system cost, your FICO tier, and any applicable adders (battery, EV charger, etc.).
Solargraf is a design and sales platform that includes satellite imagery, 3D modeling, and shade analysis. Concert Finance's integration allows installers to model different financing scenarios within Solargraf, showing you how a standard loan compares to Propel side by side, all within the same design session.

Concert Finance is the exclusive lending partner behind the Propel Transitional Ownership program. This is not a white-label relationship; Concert Finance built the financial structure that makes Propel possible. The Prepaid ESA + 25-year loan combination was designed from the ground up by Concert Finance to navigate the post-25D solar financing landscape.
The Propel structure works like this: when you sign up, a tax equity investor associated with Concert Finance becomes the legal owner of your solar system. This entity is eligible for the Section 48E commercial investment tax credit, which provides a 30% base credit plus additional bonuses. The investor claims the credit and the economic benefit is passed through as a lower monthly payment for you.
At year 5, the Early Buyout Option (EBO) is exercised automatically. The system ownership transfers to you, and you continue making the same fixed monthly loan payment. There is no balloon payment, no additional paperwork, and no negotiation. The buyout price is set at the time of signing and is already incorporated into your loan structure.
Why year 5? Because ITC recapture rules require the tax equity investor to hold the asset for at least 5 years. If ownership transferred before year 5, a portion of the tax credit would need to be returned to the IRS. Year 5 is the earliest point at which ownership can transfer without recapture risk.
This structure is unique to Concert Finance. No other solar lender offers a comparable product. SolSource/TriBeam launched their own “Propel”-branded program in February 2026, but it is a traditional lease/PPA model using Enphase equipment through Greentech Renewables, not a transitional ownership structure with an automatic ownership transfer.
Base ITC: 30% (Section 48E) + FEOC Bonus: 10% (Silfab panels, made in USA) + Energy Community Bonus: 10% (if eligible) = Up to 50% in tax credits captured by the third-party owner and passed through as lower payments.
The residential solar financing market is in transition. The expiration of the Section 25D residential ITC at the end of 2025 eliminated the single largest incentive for homeowner-purchased solar. This has created two divergent trends in solar lending.
Traditional solar lenders like Mosaic, GoodLeap, and Dividend Finance continue to offer purchase loans, but without the ITC, the economics are less favorable. A homeowner buying a $30,000 system in 2025 could claim $9,000 in tax credits, effectively making their net cost $21,000. In 2026, the same system costs $30,000 with no federal offset. This has pushed many lenders to increase dealer fees to maintain installer volume, which further inflates the true cost of borrowing.
TPO-focused structures like Concert Finance's Propel are growing rapidly because they can still access the Section 48E commercial ITC. The economics of solar in 2026 increasingly favor third-party ownership during an initial managed period, followed by ownership transfer. This is why TPO is projected to represent 69% of the residential solar market in 2026, up from approximately 45% in 2025.
Concert Finance sits at the intersection of these trends. Their standard solar loan is competitive on total cost thanks to zero dealer fees. Their Propel product addresses the ITC gap entirely. The limitation is reach: Concert Finance operates in fewer states with fewer installer partners than the industry giants.
Concert Finance is worth serious consideration if you live in a state where they operate and have a 660+ FICO score. The zero dealer fee structure is not a gimmick; it represents a fundamentally different approach to solar lending that genuinely saves borrowers thousands of dollars over the life of the loan.
The Propel product is currently the best available structure for homeowners who want to go solar in 2026 without paying full sticker price. By capturing the Section 48E ITC through a third-party owner and automatically transferring ownership at year 5, Propel bridges the gap between the expired residential credit and the still-active commercial credit. No other lender offers this.
The downsides are real. Limited state availability, higher advertised APR (though lower true cost), 660 FICO minimum, and the inability to apply independently are genuine constraints. If these limitations affect you, Mosaic or Dividend Finance are reasonable alternatives, though you should factor dealer fees into your total cost comparison.
Bottom line: If you can access Concert Finance through an approved installer, run the numbers with dealer fees included. In nearly every scenario, Concert Finance's true cost of borrowing is competitive with or lower than lenders with more attractive-sounding APRs.
