How payback works
14.2 yrs
Estimated payback

Saved per year
Solar's return is its payback period: annual bill savings against net system cost. In 2026, without the federal credit, that payback is longer but still real where rates and net metering are favorable.
Spot a fair quote in Biloxi
A typical solar installation here runs $13,400–$17,500. A trustworthy quote shows a production estimate (kWh/year) and the net cost after incentives, not just a monthly payment. Be cautious of door-to-door pressure.
- Get the production estimate in kWh and the net cash price.
- Confirm the net-metering rate your utility currently pays.
- Compare buying vs lease/PPA; ownership keeps the long-run return.
What changes your price
- System size (kW). Sized to your annual usage and roof space; bigger arrays cost more but produce more.
- Panel tier & inverter. Premium high-efficiency panels and microinverters cost more per watt.
- Roof complexity. Steep, multi-plane, or shaded roofs add labor and may need more equipment.
- Battery storage. Adding storage roughly increases project cost by half but adds backup power and self-use value.

Why it matters
Why it pays to do it right
Lock in your electricity rate
Solar trades a volatile monthly bill for a fixed up-front cost, hedging against future utility rate increases over the system's life.
Payback is the real question
With the federal credit gone in 2026, the honest math is production times your local rate versus net cost. We show that payback plainly, no inflated promises.
Net metering rules drive the return
Where your utility still offers it, net metering credits the power you export, and that buyback rate is often the single biggest swing factor in your return. Several states have scaled it back, so confirm your utility's current policy.
Pairs with a sound roof
Panels last 25+ years, so install on a roof with plenty of life left. If your roof is near end-of-life, replace it first.
Local conditions
Solar in Gulfport
The Gulfport area receives about 5 peak sun hours per day, one of the strongest solar resources in the southeastern United States, and Mississippi Power's residential rate of roughly 13 cents per kWh means every kilowatt-hour produced offsets a real cooling bill. The federal 25D credit expired December 31, 2025, so the upfront case now rests on those sun hours and that rate, and Gulfport's long cooling season ensures systems run hard from spring through fall.
Peak sun hours
~5.0/day
Gulf Coast solar resource is among the strongest in the eastern United States, with consistent high production from March through October.
Mississippi Power rate
~13¢/kWh
A meaningful retail rate makes each self-generated kilowatt-hour valuable in Gulfport's long cooling season, the primary driver of annual consumption.
Cooling season output match
Strong
Solar production peaks during the same months that Gulfport's air conditioning load peaks, making self-consumption high and net-metering credits less necessary for a well-sized system.
Incentives & net metering
The 30% federal solar credit (Section 25D) expired December 31, 2025, so 2026 cash buyers in Biloxi get $0 federal credit and net metering is now the primary incentive in MS. Mississippi Power is required to offer net metering under the Mississippi Public Service Commission's rules, though the program is more limited in scope than in some neighboring states: excess generation is credited at retail rate up to annual consumption, with any surplus compensated at a lower avoided-cost rate. Right-sizing the system to your actual consumption maximizes the value of net metering in Gulfport, and leases or PPAs can still tap the business 48E credit through 2027.
Permits
Rooftop solar in Biloxi requires a building permit, an electrical permit, and Mississippi Power interconnection approval before the system can be energized.
FAQ
Solar questions, answered for Biloxi
Is solar worth it in Biloxi given Mississippi's limited net metering?
Yes for many homes with high summer cooling loads. A system sized to your actual consumption will self-consume most production during Gulfport's long cooling season, reducing reliance on net-metering credits. The 30% federal 25D credit expired at the end of 2025, so 2026 payback now leans on the region's strong sun hours and your Mississippi Power rate; leases or PPAs can still use the business 48E credit through 2027.
How does Mississippi net metering work for Gulfport homeowners?
Mississippi Power is required to credit excess solar generation at retail rate against your bill, up to your annual consumption. Any surplus at year-end is compensated at a lower avoided-cost rate, which is why sizing to your load rather than overbuilding is the right strategy in MS.
Does the federal solar credit apply in Biloxi?
No. The 30% residential solar credit (Section 25D) expired December 31, 2025, with no phase-down, so a 2026 cash purchase in Biloxi gets $0 federal credit. Mississippi Power net metering still adds value, and leases or PPAs can use the business 48E credit through 2027.
Does hurricane risk affect solar panels in Gulfport?
Modern residential solar panels are rated for wind speeds well above standard residential building codes, and post-Katrina Gulfport racking installations are typically specified for enhanced wind uplift resistance. Most manufacturers' warranties cover storm-related damage, but confirm your installer uses hurricane-rated racking and that your homeowner's policy covers the system.
