What Mississippi still offers after the federal credit ended
Every incentive on this page is verified against Mississippi government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Southaven systems completed in 2026 get $0 from it.
Under Mississippi's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Southaven homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in Southaven tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Mississippi's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.
The 2026 numbers
| System size | Installed price (marketplace avg) | Notes |
|---|---|---|
| 6 kW | $15,480 | Small roof / low usage |
| 8 kW | $20,640 | Typical starter system |
| 10 kW | $25,800 | Family home with AC |
| 12 kW | $30,960 | Large home / EV charging |
| Home battery (optional) | $12,000-$16,000 | Backup power + self-consumption |

Mississippi rules that decide your payback
| Rule | Mississippi status |
|---|---|
| Export compensation (net metering) | Mississippi does not credit exports at retail: under the PSC's Renewable Energy Net Metering Rule, on-site self-consumption offsets usage, but excess energy exported to the utility is credited at the 'Total Benefits of Distributed Generation,' defined as the utility's Avoided Cost of Wholesale Power plus an adder (set at 2.5 cents/kWh as 'Non-Quantifiable Expected Benefits'), with an extra 2 cents/kWh Low-Income Benefits Adder for qualifying low-income customers. |
| State incentive | No state-level incentive; utility rebates may apply |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | No exclusion on record |
The Low-Income Benefits Adder (2 cents/kWh) is limited to the first 1,000 qualifying customers per the rule and is locked in for 15 years from the date the customer starts net metering service - so it is a first-come, first-served benefit. Separately, each utility must offer net metering first-come, first-served only until enrollment hits a cap of 3% of that utility's total system peak demand from the prior calendar year.

What this means for Southaven roofs
Whether solar still pays in Mississippi after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting Southaven quotes
Marketplace platforms collect bids from multiple MS installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
