Solar Panels in Mississippi: Cost, Savings and 2026 Incentives

Solar Panels in Mississippi: 2026 Guide

Going solar in Mississippi is a smart financial decision in 2026. With electricity rates at 11 cents/kWh and 5 peak sun hours per day, most homeowners see strong returns on their solar investment.

Mississippi Solar Quick Facts

• Average Electricity Rate: 11 cents/kWh (2026 EIA data)
• Peak Sun Hours: 5 hours/day
• Typical 8kW System Cost: $21,600
• Federal Tax Credit: Repealed in 2026 — no longer available for new installations

What Going Solar in Mississippi Actually Looks Like in 2026

I am going to be straight with you, because Mississippi is one of the states where the solar math deserves an honest look before you commit. The 30% federal residential credit — Section 25D — expired on December 31, 2025 under the OBBBA law, which on a typical $21,600 system here is about $6,480 that no longer comes back if you pay cash or finance with a loan. And unlike states such as Virginia or Minnesota, Mississippi does not have a deep stack of state incentives to soften that. At the numbers below the simple payback runs north of twenty years, and I would rather you hear that from me now than from a quote that buries it.

What the savings actually look like

On the systems I model for Mississippi homes, the typical owner nets about $1,010 a year in electricity-bill savings, roughly $36,824 over a 25-year system life, with panels producing for 25 to 30 years. Two things hold that number down here: electricity is cheap in Mississippi at around 11 cents per kWh, so each kilowatt-hour you offset is worth less than it would be up north, and the way the state credits exported power is less generous than full retail.

Net billing, not full-retail net metering

This is the detail that matters most and the one most pages skip. Mississippi does not require full-retail net metering. Under the Public Service Commission’s rules, the power you export is credited closer to the utility’s avoided cost than to the retail rate — Mississippi Power, for example, pays its avoided energy cost plus a distributed-generation adder of about two and a half cents per kilowatt-hour, with an extra adder for low-to-moderate-income customers, and Entergy Mississippi runs its own interconnection pathway at a credit below retail. The practical takeaway: solar pays off best here when you size the system to use most of what it produces yourself, rather than counting on selling a lot back to the grid at a low price.

The $3,500 rebate — verify before you count on it

You may see a $3,500 residential solar rebate mentioned for Mississippi. It is real in the sense that the PSC wrote it into the net-metering rule, funded through Entergy Mississippi and Mississippi Power with at least half reserved for low-income customers. But the Commission suspended solar programs back in April 2024 and the funding has been in flux since, so I will not tell you to bank on it. Before you sign anything, confirm the current status directly with the Public Service Commission or your utility — if it is open and you qualify, it meaningfully helps; if it is closed, your plan should never have depended on it.

What Mississippi does not have

To keep you from chasing incentives that are not there: Mississippi has no state solar income-tax credit, no SREC market, and no renewable portfolio standard creating demand for certificates. Some pages list a solar sales-tax or property-tax exemption for Mississippi — I have not been able to confirm those as current statewide programs, so I am not going to count them in your numbers. If you find one that applies in your county, treat it as a bonus, not a baseline.

So who should still go solar here

None of this means solar is a bad idea in Mississippi — it means the reasons are different. With the federal credit gone and a thin incentive stack, the homeowners who come out ahead tend to be the ones with high summer cooling bills who will self-consume most of their production, who plan to stay in the home long enough to ride out a twenty-year-plus payback, and who value locking in their rate against future increases as much as the raw return. One option worth pricing in a weak-incentive state like this one is a lease or power purchase agreement, where the company that owns the panels claims the commercial Section 48E credit — which runs through 2027 — and passes some of that value back to you as a lower payment; it is not cash in your pocket, but it can change the comparison. Run your exact usage through the calculator above and get at least three quotes, and if any installer is still quoting a 30% federal tax credit for a 2026 cash purchase, treat it as a sign their numbers are out of date.
