Home Solar Cost Guide

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

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

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

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

Harrington, Delaware has about 3,934 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.

If a salesperson in Harrington tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Delaware'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The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.

Delaware rules that decide your payback

RuleDelaware status
Export compensation (net metering)Net metering (not full retail): residential systems are capped at 25 kW, and effective January 1, 2024 the monthly Excess kWh Credit is valued at "the sum of the volumetric (kWh) components of the supply service charges and distribution service charges, not including the charges for societal benefits programs"; credits carry over to subsequent annualized billing periods and the customer may request a refund of the remaining balance at year end (26 Del. C. § 1014).
State incentiveGreen Energy Program — DNREC administers rebates that offset the installed cost of residential renewable energy systems including solar PV, funded by a public benefits charge on electric bills, for Delmarva Power customers (Delaware's other utilities operate similar programs). Homeowners can also sell Delaware SRECs through the state's SREC procurement program under the RPS solar carve-out (RPS: 40% renewable by 2035, 10% of that from solar).
Sales tax on the systemExempt
Property tax on added home valueNo exclusion on record

Delaware's Green Energy Program is utility-specific rather than statewide — the DNREC-run version is for Delmarva Power customers, and DNREC warns that "High demand for Green Energy Program incentives has caused a delay for some grant payments after an application receives final approval," so homeowners should not budget on receiving the grant quickly. Note also that Delaware's export credit excludes societal-benefit charges, so exported power is worth slightly less than the full retail rate.

What this means for Harrington roofs

Whether solar still pays in Delaware 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 Harrington 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

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.

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.

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.

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.

Is my roof even suitable for solar?

Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
