Home Solar Cost Guide

Is there still a solar tax credit for Rockville homeowners in 2026?

The 30% federal credit is gone for 2026 installations. What survives for Rockville: Maryland's own incentives and tax treatment - verified against state sources.

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

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

Rockville, Maryland has about 68,417 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.

If a salesperson in Rockville 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.

The 30% federal tax credit is gone for 2026 installations

The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.

Maryland rules that decide your payback

RuleMaryland 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 incentiveMaryland 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.

Property tax on added home valueExcluded

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 Rockville 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 Rockville quotes

The spread between the highest and lowest bid for the same roof routinely hits 30-50%, because solar quotes carry very different sales overheads. Two or three independent bids collected against the same system size is the single highest-value hour in the whole project.

Common questions

Is there still a federal solar tax credit in 2026?

No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.

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.

How do I check if a solar quote is fair?

Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.

What happens if my installer goes out of business?

Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.

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.
