What Maryland still offers after the federal credit ended
Every incentive on this page is verified against Maryland 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 - Preston systems completed in 2026 get $0 from it.
Under Maryland's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Preston homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
If a salesperson in Preston tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Maryland's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.
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.

Maryland rules that decide your payback
| Rule | Maryland status |
|---|---|
| Export compensation (net metering) | Full retail net energy metering: systems up to 2 MW are eligible and the program stays open until statewide net-metered capacity reaches 3,000 MW; monthly excess means the customer "is billed only customer charges for that month," and accrued net excess generation is cashed out within 30 days after the billing cycle ending before the end of April each year at the generation/commodity portion of the rate averaged over the prior 12 months (Md. Code, Pub. Util. § 7-306). |
| State incentive | Maryland Solar Access Program (Maryland Energy Administration) — an income-eligible upfront rebate for residential solar PV; the FY27 round opened July 29, 2026 with applications due May 31, 2027 and up to $10 million available from the Strategic Energy Investment Fund. Maryland SRECs, earned under the state RPS solar carve-out, remain saleable by the homeowner. |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
The old flat $1,000 Residential Clean Energy Rebate is no longer available for solar PV — MEA's current incentives page lists only the income-capped Maryland Solar Access Program for residential solar, so a household above the income limits (e.g. roughly $195,375 for a family of four in FY27) now gets no upfront state cash, only SRECs. Net metering also runs against a hard 3,000 MW statewide cap.

What this means for Preston roofs
Whether solar still pays in Maryland 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 Preston quotes
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

Common questions
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 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.
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.
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.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
