What to know before you choose a financing path

Mesa's solar market runs hot year-round, which means installation backlogs, slow-pay utilities, and equipment lead times all hit your cash flow simultaneously. The financing product that fixes one of those problems can make another one worse if you pick the wrong tool. Here's how the main options stack up.

Equipment financing for solar installers

If you're buying racking systems, conduit benders, wire-pulling equipment, service vans, or a battery storage test rig, a dedicated equipment loan or lease is almost always cheaper than a working capital line. In 2026, contractors with a 700+ FICO are seeing rates of 8.5–11% APR on equipment loans, with approvals in 1–3 business days and a typical down payment of 15–20%. Drop into the 650–699 range and expect to pay 2–4 percentage points more. The equipment itself is the collateral, which is why approval is faster and underwriting is lighter than on unsecured products. Equipment purchases placed in service this year also qualify for the Section 179 deduction up to $1,220,000, so your accountant should model the after-tax cost before you choose between a loan and a lease. Similar financing mechanics apply across the Southwest — contractors in Anaheim, CA and Albuquerque, NM face comparable rate environments and documentation requirements.

Working capital loans and lines of credit

Working capital covers the gap between when you pay crews and suppliers and when the utility interconnection check clears. Banks and SBA-preferred lenders typically want $250,000 or more in annual revenue, 24 months in business, a 1.25x debt service coverage ratio, and 6–12 months of bank statements. If you clear those bars, a working capital line runs 9–13% APR in today's market — comparable to equipment loan pricing and far cheaper than alternatives.

If your business is newer or your FICO is under 640, the SBA Microloan program lends up to $50,000 and is specifically aimed at early-stage businesses that can't yet qualify for 7(a) credit.

SBA 7(a) loans

For larger capital needs — buying a competitor, funding a warehouse, or financing a major fleet expansion — SBA 7(a) loans go up to $5,000,000 at 8.5–11% APR with up to 10-year terms on equipment. The minimum FICO is 640+, and approval runs 30–45 days. If you also own real property in the business, lenders will want it as additional collateral. The same SBA infrastructure that serves solar contractors in Mesa supports general construction financing across the region; the construction equipment financing landscape in Mesa covers overlapping lender pools and SBA options that solar contractors often tap for heavy equipment.

Invoice factoring

If slow-paying commercial or utility customers are the actual problem, factoring lets you sell those receivables at 80–90% of face value and get cash in 24–48 hours. Fees run 1–3% of face value per month, which sounds small but compounds quickly — factoring is a cash-flow bridge, not a long-term funding strategy. Use it to cover a payroll cycle or a supplier deposit, not to fund ongoing operations.

Merchant cash advances — use sparingly

MCAs are fast and credit-flexible, but the 35–50% APR equivalent means they belong only in genuine emergencies where you have a clear, short payback path. Most solar contractors who take an MCA to solve a cash-flow problem find they've created a larger one. Exhaust factoring and online working capital lines first.

What lenders look at

• Personal credit: 640+ for SBA; 620+ for equipment; 580+ for factoring
• Time in business: 24 months for SBA 7(a); 12 months for most equipment lenders; less for factoring
• Revenue: $250,000+ annual for unsecured working capital
• DSCR: 1.25x minimum across bank and SBA products
• Origination fees: Budget 1–3% of loan amount on most products

The product that gets you approved fastest is rarely the one that costs least over the life of the project. Running a parallel application through an SBA-preferred lender and an online lender is almost always worth the extra week.
