What to know before you choose

Spokane's solar market runs on the same project-finance rhythms as the rest of the Northwest: residential installers carry 60–120 days of receivables while waiting on utility interconnection approvals, and commercial contractors often front six-figure material costs before a draw schedule kicks in. That gap is where financing earns its place — but the wrong product costs far more than it solves.

Equipment financing is the starting point for most solar installation companies. Panel strings, inverters, racking systems, and service vehicles all qualify. Rates for contractors with 700+ credit run 8.5–11% APR in 2026, with approval in as little as 1–3 days through online lenders. Expect to put 15–20% down, and note that the IRS Section 179 deduction limit is $1,220,000 for 2026 — buying rather than leasing often wins on after-tax cost for firms that can use the deduction. Equipment loans also build business credit history over time, which matters when you need a larger line later.

Working capital lines and term loans cover payroll and materials between draws. Typical APRs run 9–13% for well-qualified borrowers. Lenders generally want to see $250,000 or more in annual revenue and will review 6–12 months of bank statements. Monthly debt service across all obligations should stay under 45–50% of revenue, and most bank underwriters require a debt service coverage ratio of at least 1.25x — meaning your net operating income needs to be 25% above total debt payments.

SBA 7(a) loans are worth the paperwork for larger capital needs. Maximum loan amount is $5,000,000, rates run 8.5–11%, and terms stretch to 10 years on equipment. The catch: you need 24 months in business, a 640+ credit score, and 30–45 days for approval. Guarantee fees add another 2–3% at closing. If you're bidding on a large commercial or municipal project in Spokane and need a committed facility before signing a contract, SBA is viable — but start the application before you need the money.

Invoice factoring solves the receivables problem directly. Factors advance 80–90% of invoice face value within 24–48 hours, at a fee of 1–3% of face value per month. That's expensive annualized, but it keeps a job moving when a general contractor is slow-paying. Solar installers doing commercial work across Eastern Washington — or those with accounts in markets like Albuquerque or Anaheim where net terms are standard — often factor selectively rather than as a permanent capital strategy.

Merchant cash advances should be a last resort. The APR equivalent runs 35–50%, and daily repayments can choke cash flow on a slow-production month. Use them only for a short, defined gap with a clear payoff date.

Fair-credit borrowers (620–679 FICO) qualify for most products but pay 2–4 percentage points more than prime-tier competitors. That spread can flip a deal from profitable to marginal on thin-margin residential jobs. Improving a score before applying — or pledging equipment collateral to reduce lender risk — is often worth a 30–60 day delay.

One cross-industry note: Spokane contractors who already manage equipment-heavy operations know that separating financing by asset class keeps balance sheets clean. The same discipline that drives commercial equipment financing decisions for small Spokane businesses applies here — match the loan term to the asset's useful life and don't fund long-lived panels with short-term working capital lines.
