6-month runway
Startup cost plus six months of burn: a rough floor for how much cash to have in hand before you open, since most businesses are not profitable from day one.
$73,000 to $279,400
Check the breakdown before using this figure: if upfront costs already include a working-capital reserve, this formula counts additional runway on top of it. Listed monthly costs may be incomplete.
How to lower these costs
Working capital / bonding reserve for payroll between deposit and completion
Working capital / bonding reserve for payroll between deposit and completion is one of the largest one-time costs ($20,000 to $80,000). Look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
Initial inventory — panels, inverters, racking, BOS (balance of system)
Initial inventory — panels, inverters, racking, BOS (balance of system) is one of the largest one-time costs ($10,000 to $60,000). Look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
Initial inventory — panels, inverters, racking, BOS (balance of system), monthly
Initial inventory — panels, inverters, racking, BOS (balance of system) runs $500 to $3,000/month. Negotiate the rate up front, shop multiple vendors, or delay this line item until revenue can cover it.
Launch marketing (Google/LSA ads, yard signs, referral program setup), monthly
Launch marketing (Google/LSA ads, yard signs, referral program setup) runs $500 to $2,500/month. Negotiate the rate up front, shop multiple vendors, or delay this line item until revenue can cover it.

Frequently asked questions
How much does it cost to start a solar installation business?
Realistically $60,000–$200,000+ for a licensed, insured, stocked operation: vehicle (~$15k–$35k), tools (~$8k–$20k), initial panel/inverter inventory ($10k–$60k), insurance ($1k–$4k down), 6 months of working capital, and marketing ($3k–$10k). Sub-50k entrants typically subcontract licensed crews or sell-only (referral partners) rather than installing.
What's the cheapest way to get into solar?
Pure sales/dealer model: skip owning panels and installation crews; you generate leads and sell to established installers for a 8–15% commission, requiring just licensing (~$1k), software (~$200/mo), and marketing. Most light-touch entrants lose money because commissions run 8–15% while sale cycles stretch 30–90 days, so they burn marketing cash before first payouts.
Can I finance the startup costs?
SBA 7(a) or equipment-financing loans tied to specific assets (vehicle, tools) are the common routes; inventory lines from distributors (Wesco, BayWa, CED Greentech) give 30–60 day terms once you have volume history. Pure bootstrapping via subcontracted labor and per-job panel ordering is common for first-year operators.
What ongoing monthly costs should I expect?
Software subscriptions (Aurora, OpenSolar ~$100–$400/mo), insurance ($300–$1,000/mo), replacement/safety gear, vehicle fuel and maintenance, and — critically — marketing, which in solar often runs $1,500–$4,000+ per closed sale on competitive Google/LSA lead gen.
What hidden costs hurt solar installers most?
Warranty/service callbacks (2–5% of jobs generate truck rolls you must eat), permitting rework when jurisdictions reject designs, panel breakage/theft, and price-per-watt compression: national average residential install price fell from ~$3.50/W to ~$2.80–$3.00/W over 2022–2025 (Wood Mackenzie/SEIA), so quoted cost-of-goods assumptions age badly.
