Most homeowners finance solar with a solar loan, HELOC, or cash. Solar loans require no down payment and preserve ITC eligibility — but interest adds $2,000–$5,000 to total cost over 10–20 years.
Solar loans
Unsecured solar loans are the most common financing — rates 4–9% APR, terms 10–25 years.
- You own the system and claim ITC
- Monthly payment often below old electric bill
- Compare APR and dealer fees across lenders
HELOC vs solar loan
HELOCs may offer lower rates if you have equity, but your home is collateral.
