Home Solar Cost Guide

What Mississippi still offers after the federal credit ended

Every incentive on this page is verified against Mississippi government sources - and the expired ones salespeople still quote are called out.

The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Mendenhall systems completed in 2026 get $0 from it.

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 Mendenhall homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.

The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.

Mississippi rules that decide your payback

RuleMississippi 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 incentiveNo state-level incentive; utility rebates may apply
Sales tax on the systemNot exempt - taxed like any purchase
Property tax on added home valueNo 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.

What this means for Mendenhall roofs

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.

Getting Mendenhall quotes

Marketplace platforms collect bids from multiple MS installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions

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.

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.

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.

How long do solar panels actually last?

Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.

How much does home solar cost in 2026?

The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
