Solar Panels in Mississippi (2026 Guide)

Q: How much do solar panels cost in Mississippi in 2026?

About $2.50–$3.10 per watt installed — roughly $15,000–$18,000 for a 6 kW system and $25,000–$31,000 for a 10 kW system, before incentives.

Q: Does Mississippi have net metering?

Mississippi has a 'net metering' policy, but exported power is credited at roughly the avoided-cost (wholesale) rate plus a small adder for many customers — not the full retail rate. Low-income customers can qualify for a higher credit and an upfront rebate.

Q: Does Mississippi have a state solar tax credit?

No. There is no state income-tax credit for residential solar in Mississippi in 2026. Incentives are limited overall.

Q: Is solar worth it in Mississippi?

It can be, but the case is modest. With below-retail export credits and few incentives, payback is longer — so it depends on your usage, your roof, how long you'll stay, and whether you self-consume or add a battery.

Here's the honest picture: Mississippi has good sun and reasonable install costs, but limited incentives and below-retail credit for exported power. Solar can pay off for the right home — particularly high-usage households that use most of their power during the day — but it's a more careful calculation than in heavily incentivized states. We'll give you the real numbers, not a sales pitch.

What drives your cost in Mississippi

Your quote depends on system size, roof type and condition, equipment tier, and whether you add storage. Because exports are credited below retail, sizing to your own usage and shifting consumption to daytime tends to produce the best return.

Net Metering in Mississippi — Read This Carefully

Mississippi has a net-metering rule, but it's not full retail. For many residential customers, exported power is credited at roughly the avoided-cost (wholesale) rate plus a small adder — meaningfully less than the retail rate you pay. The Public Service Commission did add benefits for low-income customers, who can qualify for a higher export credit and an upfront installation rebate. For everyone else, the takeaway is the same as in similar states: the power you use yourself is worth far more than the power you export, so self-consumption and possibly a battery drive the economics.

Major Mississippi Utilities

The main utilities are Entergy Mississippi and Mississippi Power (a Southern Company utility), along with several electric co-ops. Net-metering credit rates, any caps, and the low-income provisions are set by the Mississippi Public Service Commission, so confirm the current terms for your specific utility before you sign.

Is Solar Worth It in Mississippi?

It can be — but modestly. With below-retail export credits and few incentives, payback periods run longer (often 12+ years for cash purchases) unless you qualify for the low-income rebate. Solar makes the most sense for high-usage homes with a good roof and long-term ownership, especially when you self-consume most of your production. A custom quote tied to your utility and usage will give you the honest answer. See also Is Solar Worth It in 2026?
