Going solar in Mississippi
The Magnolia State’s sunny skies and mild winters make it a natural fit for solar panels––they can reduce your carbon footprint and your reliance on the utility electric grid.
Factor in the federal solar tax credit, and Mississippians can cut the cost of solar by thousands of dollars, speeding up your payback period and increasing the value of your investment.
Here's what you should know about going solar in Mississippi.
Cost
How much do solar panels cost in Mississippi?
Solar panels will save you a lot of money over time, but the upfront costs aren't cheap. The average Mississippi homeowner needs a 10.95 kW solar panel system to cover their electricity needs, which comes out to $30,460 before incentives. Prices range from $25,891 to $35,029, but after the federal tax credit, that drops by 30%.
While this may sound high, it will pay off in Mississippi. That's why over 800 Mississippi homeowners have used EnergySage to receive and compare quotes for solar installations. You can expect to earn back your initial solar investment through electricity savings in about 12.71 years, while most systems last at least 25 years. You'll often see this number referenced as your solar payback period.
Solar panel systems are expensive, but there are ways to finance your investment and reduce upfront costs.
Cash purchase: You pay for your system outright, which typically provides the best long-term savings.
Solar loan: You pay for your system in monthly installments like a lease but maintain ownership like a cash purchase. Generally, the best solar loans are subsidized clean energy loans through local incentive programs. If you don’t have access to that, a home equity loan or a personal loan are often your next best options. Private solar loans typically come with higher interest rates or upfront fees.
Solar lease or power purchase agreement (PPA): You make monthly payments on your system like a loan, but a third-party company owns your system. You’ll either sign a solar lease or purchase the electricity the panels generate through a PPA. Third-party ownership models typically deliver the lowest savings and have earned some bad press. If you choose this financing option, read the fine print: You can get trapped in them for longer than you'd like.

Incentives
What are the best solar rebates and incentives in Mississippi?
Incentives help bring solar's price tag down considerably in Mississippi. Here are the major ones to know about:
| Incentive | Average savings in Mississippi | Description |
|---|---|---|
Residential Clean Energy Tax Credit, formerly the federal investment tax credit (ITC) | $9,138 | Lowers your solar panel system's cost by 30% |
Is net metering available in Mississippi?
Mississippi doesn’t offer true net metering, but if you connect your solar panel system to the grid, you can benefit from net billing. The catch is that the utility companies only offer partial credit for every kWh you send to the grid. You'll have to sell the electricity to them at a significant discount, compared to what they’ll charge you to buy that electricity back later. Consider installing a solar battery to squeeze the most possible value out of your solar panels under net billing.
Equipment
Equipment quality
The more efficient a solar panel is, the more power per square foot. As of 2025, the most popular solar panels have a rated output of 450 watts. To get the most out of your solar energy system, choose panels with at least that much power output.
Your solar inverter setup is also important consideration—make sure it suits your roof’s layout.
And if you’re interested in a solar battery, it’s best to choose one that integrates with that inverter.
The best equipment tends to be more expensive, but it will often save you more money in the end. Premium equipment often has the best warranty terms, guaranteeing 25-40 years of coverage for repairs, replacements, and the lowest degradation rates (meaning they’ll maintain more of their power output for longer).
