Scan the list below, find the option that matches your situation — startup or established, equipment purchase or cash-flow gap, strong credit or credit-challenged — and go straight to that guide. The orientation below will help if you're not sure which bucket you're in.

What to know before choosing a financing path

San Bernardino County is one of the largest solar installation markets in California, driven by high utility rates, commercial warehouse rooftops in the Inland Empire, and a steady pipeline of residential retrofits. That volume is good for business and brutal for cash flow: projects run 60–120 days from signed contract to final utility interconnection sign-off, and most installers are carrying payroll, panel inventory, and permitting costs the entire time. The right financing tool depends on why you need capital and how long you can wait for it.

Working capital loans and lines of credit are the workhorses for established installers. Banks and SBA-approved lenders typically want $250,000+ in annual revenue, 6–12 months of bank statements, and a debt-service coverage ratio of at least 1.25x. SBA 7(a) lines run 8.5–11% APR with terms up to 10 years on equipment draws; the tradeoff is a 30–45 day approval window and a guarantee fee of 2–3%. If your books are clean and your pipeline is predictable, this is usually the lowest-cost path.

Solar equipment financing moves faster — approvals in 1–3 days from most online lenders — and the collateral is the equipment itself, which lowers underwriter risk. Expect 8.5–11% APR with a 700+ FICO and a 15–20% down payment. Scores in the fair-credit range (620–679 FICO) push rates up by 2–4 percentage points but don't shut the door. Section 179 lets you deduct up to $1,220,000 in qualifying equipment in the year of purchase, which changes the after-tax math meaningfully — solar racking systems, inverters, and service vehicles all qualify. Other capital-intensive industries in the region — from agriculture to healthcare — run the same equipment-loan playbook; San Bernardino commercial farmers financing irrigation upgrades face nearly identical approval criteria and tax incentive decisions.

Invoice factoring is the fastest fix for a receivables crunch. A factoring company advances 80–90% of your invoice face value within 24–48 hours, then collects from your customer directly. Fees run 1–3% of face value per month. It's expensive annualized, but it's not a loan — no debt on the balance sheet, no DSCR calculation, and credit score matters far less than the creditworthiness of your commercial customer (a utility or a general contractor, in most solar deals).

Bridge loans and merchant cash advances are last-resort tools. MCAs can carry 35–50% APR equivalents. Use them only when a specific, dated payment event (a utility rebate check, a final draw from a GC) makes the math work on a short payoff window. Installers working commercial jobs in markets like Anaheim or across the Southwest in Albuquerque report similar patterns: the projects that blow up cash flow are usually the large commercial jobs where the contract terms weren't negotiated to include progress payments.

Key separators at a glance:

Situation	Best-fit tool	Typical speed
Buying panels, inverters, racking	Equipment loan / lease	1–3 days
Covering payroll between draws	Working capital line	1–5 days (online) / 30–45 days (SBA)
Commercial customer slow to pay	Invoice factoring	24–48 hours
Startup, under 2 years in business	SBA Microloan / equipment loan	2–4 weeks
Expansion, new service vehicles	SBA 7(a)	30–45 days

What trips people up most: applying for the wrong product. A contractor with a 90-day receivable gap doesn't need a 10-year term loan — they need factoring or a short draw on a line. Conversely, funding a $400,000 fleet purchase with an MCA because the approval was fast is a math error that compounds fast. Work backward from the specific cash need, its duration, and when you'll have the revenue to repay it. The guides linked below are organized by exactly those criteria.
