A home equity line of credit (HELOC) is one of several ways to finance solar panels, offering potentially lower interest rates than dedicated solar loans in exchange for using your home as collateral. HELOCs often offer lower rates than solar-specific loans, but carry the risk of using your home as collateral and typically have variable rates.
HELOC vs. Solar Loan Comparison
| Factor | HELOC | Solar Loan |
|---|---|---|
| Interest rate | Often lower, typically variable | Higher, often fixed |
| Collateral | Your home | Usually unsecured or solar equipment |
| Tax deductibility | Interest may be deductible if funds improve the home | Generally not deductible |
| Approval speed | Slower — requires home equity assessment | Often faster |
Why Homeowners Consider a HELOC
HELOCs often offer lower interest rates than dedicated solar loans, since they’re secured by home equity — potentially saving significant money over the loan term for qualified borrowers.
The Risk of Using Home Equity
Unlike an unsecured solar loan, a HELOC uses your home as collateral — defaulting carries the risk of foreclosure, a meaningfully higher stakes proposition than a standard solar loan default.

Variable Rate Considerations
Most HELOCs carry variable interest rates that can rise over the loan term — factor in potential rate increases when comparing total cost against a fixed-rate solar loan.
Tax Deductibility
HELOC interest may be tax-deductible if the funds are used to improve the home (which solar installation typically qualifies as) — consult a tax professional to confirm your specific situation.
