The 4 things that actually determine "worth it"

Electricity rate. Rhode Island: 28.30¢/kWh. National avg: 18.83¢. You’re 50% above average — solar looks strong here.
Sunshine. Rhode Island: 4.0 peak sun hours/day. National avg: 4.5. Below average — you’ll need a slightly larger system for the same production.
Install cost in Rhode Island. $3.30/watt (state avg). Above national $3.00/W — market is smaller / labor more expensive.
Incentive stack. Federal ITC 30% applies universally. None (Renewable Energy Fund rebates end 2024) Net metering: Yes, 1:1 Full incentive breakdown →

Break-even analysis

Your solar system in Rhode Island needs to save $13,860 in electricity to pay for itself. At $1,934/year savings, that’s 7.2 years. Panels are warrantied for 25 years and typically last 30+ — meaning 22.8+ years of free electricity after breakeven.

Common objections addressed

“What if I move before payback?”

Homes with paid-off solar typically sell for ~$15,000-$25,000 more than comparable homes without. If you owe money on the panels (loan), the sale is more complex. Cash or fully-paid-off systems recover most or all of the remaining "unused" value at sale.

“Won’t rates drop?”

U.S. residential electricity rates have risen ~4%/year over the past decade. Even if rates flatline, the payback above holds. If rates rise, your solar looks better in retrospect.

“What about hail / storms?”

Solar panels are rated for 1-inch hail at 50 mph. Damage claims are covered by homeowner’s insurance in almost all cases (verify with your carrier).
