Scan the list below, find the description that matches your immediate need — gap between a signed contract and first draw, a new truck or panel inventory, a slow-pay commercial customer — and click through. Each guide covers qualification, costs, and next steps for that one situation.

What to know before you pick a product

Solar installation cash flow doesn't look like a typical contractor's. You front labor and materials weeks before utility interconnection is approved, customers sometimes delay final payment until inspection closes, and equipment orders for a busy Q3 season need to be placed in Q1. That timing gap is where most Chula Vista solar firms get squeezed, and the wrong financing product makes it worse.

The five products solar contractors actually use — and who each fits:

• Equipment financing — Best for panel racking systems, wire management equipment, service vehicles, or lift equipment. Approvals run 1–3 days, lenders typically want 15–20% down, and rates for 700+ FICO borrowers sit at 8.5–11% APR in 2026. The equipment secures the loan, which makes this accessible even for firms with limited operating history. Equipment loans also build business credit history over time, which matters if you plan to pursue larger SBA facilities later. Solar contractors in comparable markets like Anaheim and Albuquerque consistently rank this as the first product to establish.

• Working capital lines of credit — Best for payroll and subcontractor payments between project milestones. Most unsecured lines for solar contractors require at least $250,000 in annual revenue. Expect 9–13% APR on bank-grade lines in 2026. Lenders will pull 6–12 months of bank statements and want to see a debt service coverage ratio above 1.25x before approving.

• SBA 7(a) loans — Best for equipment purchases above $150K, business acquisitions, or funding a branch expansion across San Diego County. Maximum loan amount is $5,000,000, rates run 8.5–11%, and terms on equipment go up to 10 years. Minimum credit score is 640+, and you need 24 months in business. Approval takes 30–45 days — plan accordingly. The SBA charges a guarantee fee of 2–3%, which rolls into the loan.

• Invoice factoring — Best when a slow-pay commercial or municipal customer is choking your cash flow right now. Factoring companies advance 80–90% of the invoice face value within 24–48 hours and charge 1–3% of face value per month. Your business credit score matters less than the creditworthiness of the customer you're factoring. Similar commercial equipment-financing dynamics apply across service businesses in Chula Vista — the commercial financing structures used by HVAC contractors in the same market illustrate how lenders evaluate project-based service firms generally.

• Merchant cash advances — A last resort. MCAs carry an APR equivalent of 35–50% and are structured as a percentage of daily deposits, which destroys cash flow on thin-margin residential installs. Use only if you have no other bridge and a large receivable closing within 30–60 days.

What trips people up:

Most denials come from three places: a personal FICO below 640, a debt-to-income load already above 45–50% of revenue, or applying for the wrong product. A contractor who needs $40,000 to cover labor between milestone payments doesn't need an SBA 7(a) — they need a line of credit or factoring. A contractor buying $180,000 of panel inventory shouldn't take a merchant cash advance when equipment financing at 9% is available. Section 179 also changes the equipment math: in 2026 you can expense up to $1,220,000 of qualifying equipment in the year of purchase, which often makes financed equipment purchases more tax-efficient than cash purchases.

Credit score is the single fastest lever. One in five credit reports contains an error — pull yours before you apply, dispute anything inaccurate, and recheck. Fair-credit borrowers (620–679 FICO) pay 2–4 percentage points more than good-credit borrowers on the same product. That spread is worth fixing before you submit an application.
