Tax credit
#01
Federal Residential Clean Energy Credit (Section 25D) - ENDED
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025. Cash and loan purchases made now receive no federal tax credit, and Mississippi has no state solar tax credit to fall back on.

#02
Federal Commercial ITC (Section 48E) - via Lease / PPA
Section 48E, the commercial Clean Electricity Investment Credit, survives at 30 percent and is available to third-party owners of residential systems under leases and power purchase agreements. The provider claims it and may reflect part of the value in the rate offered. Ask what they claim and what actually reaches you, and confirm with a tax advisor.

#03
Export credit: avoided cost plus a 2.5 cent Distributed Generation Benefits Adder
Mississippi credits exported electricity at the utility avoided cost rate plus a Distributed Generation Benefits Adder of 2.5 cents per kWh. A Public Service Commission order in January 2025 updated the Entergy Mississippi tariff to 5.5 cents per kWh for customers not eligible for the low-to-moderate income adder. Against a residential rate around 16 cents per kWh, an exported kilowatt hour is worth roughly a third of one consumed on site, so self-consumption is where the value sits.

#04
Low-to-moderate income adder - ask by name
Qualifying low-income customers receive an additional adder on top of the standard export credit, taking the Entergy Mississippi figure to 7.5 cents per kWh under the January 2025 order against 5.5 cents for other customers. The additional 2 cents per kWh applies to the first 1,000 qualifying customers to install, running for 15 years from the date the customer begins taking net metering service, and eligibility has been expanded to households with annual income up to 250 percent of the federal poverty level. It is not applied automatically, so ask whether your household qualifies and ask to see the determination.
Program
#05
Adders grandfathered for 25 years
The 2.5 cents per kWh Distributed Generation Benefits Adder is grandfathered for a period of 25 years, and the low-income benefits adder is likewise grandfathered for 25 years. That is close to the working life of a solar system, so a customer enrolling now carries the adder terms for essentially the life of the array rather than being exposed to annual revision.
Utility
#06
Utility terms differ; check who bills you
Mississippi is served by Entergy Mississippi in the centre and west, Mississippi Power in the southeast, TVA distributors in the northeast, and roughly 20 rural electric cooperatives. The Public Service Commission tariffs apply to the regulated investor-owned utilities; TVA distributors follow the TVA framework and cooperatives set their own terms. Mississippi Power filed an RENM-3 schedule in December 2024 to replace RENM-2, removing a provision that disallowed credits from offsetting fixed charges on a bill.

Net metering · Mississippi
Avoided cost plus adders, grandfathered 25 years
Mississippi does not offer retail-rate net metering. Exported electricity is credited at the utility avoided cost rate plus a Distributed Generation Benefits Adder of 2.5 cents per kWh, and a Public Service Commission order in January 2025 updated the Entergy Mississippi tariff to 5.5 cents per kWh for customers not eligible for the low-to-moderate income adder and 7.5 cents for those who are. Against a Mississippi residential rate around 16 cents per kWh on recent EIA figures, an exported kilowatt hour is worth roughly a third of one consumed as it is generated, or a little under half with the income adder applied. Two features make this arrangement better than a bare avoided-cost regime. First, the adders are grandfathered for 25 years, which is close to the working life of a system, so a customer enrolling now is not exposed to annual revision the way Utah or Louisiana customers are. Second, the low-to-moderate income adder is genuinely accessible: eligibility has been expanded to households with annual income up to 250 percent of the federal poverty level, which in Mississippi reaches a large share of households, though the additional 2 cents per kWh is limited to the first 1,000 qualifying customers to install and runs 15 years from the start of net metering service. The design conclusion is the familiar one for an avoided-cost state: build around what your household consumes during daylight, shift flexible loads into the generating window, and treat storage as doing real arbitrage rather than only providing backup.
Worth checking before you sign:
