The 4 things that actually determine "worth it"

Electricity rate. Mississippi: 16.76¢/kWh. National avg: 18.83¢. You’re 11% below average — cheap grid electricity makes payback slower.
Sunshine. Mississippi: 4.6 peak sun hours/day. National avg: 4.5. Near average sun.
Install cost in Mississippi. $2.80/watt (state avg). Cheaper than national $3.00/W — competitive installer market here.
Incentive stack. Federal ITC 30% applies universally. No state income-tax credit in Mississippi. Net metering: Ended 2022; net-billing-only for new systems Full incentive breakdown →

Break-even analysis

Your solar system in Mississippi needs to save $11,760 in electricity to pay for itself. At $1,317/year savings, that’s 8.9 years. Panels are warrantied for 25 years and typically last 30+ — meaning 21.1+ 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).
