What Mississippi pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is Mississippi's current rule in plain words, with the official source.
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 Bay St. Louis homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Bay St. Louis, Mississippi has about 10,526 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
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.
The honest 2026 answer for Bay St. Louis: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Mississippi's export compensation, covered in the net metering section.
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.

Common questions
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.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
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.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
