MCA for solar installers 2026 — the merchant's funding guide.

The 60-second answer

If you run a solar installation business doing $80K–$300K/month in deposits, have been operating for 24+ months, and have a 580+ FICO with a clean contractor license and established dealer-finance relationships, you can almost certainly get funded in 2026 — typically at a 1.30–1.38 factor on a 9–12 month daily-ACH term. The fundable amount usually lands at 0.8–1.3x your monthly deposits, adjusted for dealer-finance cycle visibility.

The two things that move your rate down: documented dealer-finance funding statements (proving the M1/M2 cycle is real and predictable), and a healthy forward-pipeline of signed contracts and permits in flight. The two things that move your rate up: dealer-finance chargebacks or clawbacks visible on statements, and any open complaints with the state attorney general or contractor board (solar has high consumer-complaint volume).

Why solar installers are a unique MCA category

Solar installation looks like construction on the surface but underwrites differently. Three structural factors drive the pricing:

• Dealer-finance milestone cycles. Most residential solar revenue arrives via partners like GoodLeap, Sunlight Financial, Service Finance, or Mosaic. They pay in milestones — M1 (often 60–70% of contract value at install completion) and M2 (30–40% at PTO/permission to operate). That cycle is predictable but lumpy.
• Policy sensitivity. The Investment Tax Credit (ITC), state net-metering rules, NEM 3.0 in California, and changing utility interconnection rules all swing installer revenue quarter-to-quarter. Funders that specialize ask about your geographic and policy exposure; generalists just decline.
• Chargeback and clawback risk. Dealer-finance partners can clawback funding if a project doesn't hit PTO within their window (often 12 months) or if a customer disputes the installation. Funders look for clawback activity on statements.

Realistic factor rates by tier

Three tiers of solar installer MCA pricing, based on real 2026 quotes:

• A-paper solar installer (5+ years operating, 650+ FICO, $200K+ monthly deposits, established dealer-finance relationships, no clawback history, no prior MCA): 1.26–1.32 factor on 12-month daily ACH. Funders: Forward Financing, CFG Merchant Solutions, Credibly premium tier.
• B-paper solar installer (24–60 months, 580–650 FICO, $80K–$200K monthly, maybe one prior paid-off advance, some clawback activity): 1.32–1.40 factor on 9–12 month term. Funders: Credibly standard, Reliant Funding, Mantis Funding, Greenbox Capital, Rapid Finance.
• C-paper solar installer (under 24 months OR 500–580 FICO OR currently stacked OR significant clawback history): 1.42–1.50 factor on a 6–9 month term, often a smaller advance ($25K–$60K). Many quality funders decline this tier entirely because solar default risk concentrates here.

The bank-statement story that gets you funded

Underwriters look at 6–12 months of business bank statements for solar installers — longer than most trades to see the full dealer-finance cycle. Here's what they want:

What they want

• Predictable dealer-finance milestone deposits. Recurring deposits labeled GoodLeap, Sunlight, Service Finance, Mosaic, EnerBank, Sunnova, etc. The cadence (multiple deposits per week at varying sizes) tells underwriters M1/M2 is running cleanly.
• Supplier ACH to familiar names. Soligent, BayWa r.e., CED Greentech, Krannich Solar, or major panel and inverter distributors. These tell underwriters you're a working installer.
• Insurance and bonding premium debits. Monthly GL carrier, workers comp, and (for commercial) surety premium debits.
• Payroll on a real schedule. Weekly or biweekly payroll for crews, with stable headcount. Solar default risk concentrates in operators paying labor inconsistently.
• Permitting fees visible. Recurring municipal permit ACH (small outbound payments to city/county building departments) signals real installation volume — not just sales activity.

What kills the deal

• Dealer-finance clawbacks visible on statements. Reverse-direction ACH from GoodLeap, Sunlight, or Service Finance is a giant red flag. It means projects aren't hitting PTO, customers are canceling, or your installation quality is triggering disputes.
• State attorney general complaints or BBB clusters. Solar has high consumer-complaint volume and most state AGs publish active cases. Open AG actions are a hard decline.
• NSF and overdraft fees. 3+ NSFs in a 6-month window is a near-instant decline. NSFs in solar often reflect M1/M2 cycle mismanagement, which underwriters read as a direct daily-ACH coverage problem.
• Heavy cancellation volume. If statements show reversed deposits (customer cancels before install), funders read it as sales-process risk and either decline or downsize materially.
• Stacking signatures. Two or more concurrent MCA daily debits trigger decline at most quality funders. Solar stacking is especially dangerous because of the M1/M2 gap.

Which funders actually like solar installers

Based on 2026 placement data:

• Forward Financing — strong solar appetite on A-paper installers with established dealer-finance relationships. Fast funding, reasonable reconciliation if a quarter is slow.
• CFG Merchant Solutions — likes established commercial-solar installers with $200K+ monthly deposits. Premium pricing, conservative on dealer- finance clawback exposure.
• Credibly — broad solar appetite across A and B paper. Publishes a prepayment discount schedule, which matters in solar because M2 milestones often clear in lumps that let you prepay.
• Mantis Funding — solid B-paper solar appetite for established residential installers. Reasonable on M1/M2 cycle if you can document.
• Greenbox Capital — willing on B and lower B paper. Smaller advance sizes, faster decisions.

Funders to be cautious with for solar: anyone aggressively quoting under 1.22 on a first solar MCA (bait-and-switch or fee-loaded contract), anyone who doesn't ask for dealer-finance verification, and any broker who promises "solar-specific" rates without naming the funder. Solar is one of the most-stacked segments in MCA, and the consequences (dealer-finance clawback + MCA stack = rapid business closure) are severe.

How much you can actually get

The fundable-amount formula most quality funders use for solar installers:

• First position: 0.8–1.3x monthly deposits, capped at $500K for most single-entity installers, $1M+ for multi-state operations with audited financials and verified dealer-finance volume.
• Second position (if allowed): 0.3x monthly deposits — most quality funders decline solar stacks outright because of M1/M2 cycle compounding with clawback risk.
• Renewal: Most funders renew at 50%+ paid-down. The renewal advance is typically the original + 15–25% if the file has aged through a full ITC and net- metering cycle without clawback activity.

A $150K/month solar installer should target a $120K–$170K first-position advance, not $300K. Oversizing creates a daily-ACH burden that breaks the moment dealer-finance timing slips (one customer delaying PTO by 30 days affects the entire cohort) and starts the failure spiral.

What to do before you apply

Six steps that materially improve your rate and approval odds for solar installers:

• Pull your dealer-finance funding statements. GoodLeap, Sunlight, Service Finance, and Mosaic all provide installer dashboards. Print 6–12 months of funding history before applying.
• Reconcile your last 6–12 months of statements. Find every NSF and clawback, and have an explanation tied to specific projects.
• Document your forward pipeline. A simple spreadsheet listing signed contracts, permits in flight, and expected install dates dramatically improves your underwrite — it shows revenue is coming, not just sitting in past statements.
• Verify your license and state AG record. Pull your contractor board record and search your state AG's consumer-complaint database. Surprise findings during underwriting kill solar deals more often than any other trade.
• Resolve any open dealer-finance disputes before applying. Even a small open clawback dispute reads as future revenue-disruption risk.
• Get clarity on use of funds. "Pre-install material deposit for 12 signed contracts in next 60 days," "payroll bridge before three M2 milestones clear in 45 days," "marketing into NEM-favorable adjacent state" all underwrite well. "Working capital" doesn't.

The 2026 policy backdrop — a brief note

Solar funding decisions in 2026 are happening against an unusually active policy backdrop: ITC step-down questions, state net-metering revisions, and shifting interconnection rules in several large markets. Funders that specialize in solar will ask about your geographic exposure and your forward-pipeline assumptions. The right answer is honest, specific, and tied to documented contracts — not generic optimism. Installers who can clearly articulate their state-by-state book and policy exposure get better terms than installers who hand-wave.

The honest tradeoff

An MCA is expensive money. For a solar installer, a 1.32 factor on a 12-month term works out to roughly 50–55% APR-equivalent. That's the cost of speed and flexibility — no collateral, no tax-return underwriting, no 30–60 day LOC setup, funding usually in 1–3 business days.

For a confirmed-ROI use (pre-install material buy for a documented signed-contract pipeline, payroll bridge before specific M2 milestones clear, marketing into a policy-favorable adjacent state), the math often works. For "smoothing out a slow quarter" or "covering a dealer-finance clawback," it almost never does — that's how solar installers end up stacked and then closed.
