What home solar costs in Lewes - and the 2026 rules that changed the math
The solar industry is still quoting like it is 2025, but the 30% federal credit died on December 31, 2025. Here is what a Lewes homeowner actually pays in 2026, what Delaware still offers, and how to compare quotes without getting played.
Installed home solar for Lewes homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Lewes systems completed in 2026 get $0 from it.
Under Delaware's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Lewes plus 12 surrounding towns within 40 km form one installer market of about 59,148 people - quotes should not vary much by town.
With 12 towns within 40 km, Lewes sits in a shared installer market of about 59,148 people - the same crews quote the whole area, so prices should not differ much from one town to the next. Big differences between quotes reflect sales margin, not your roof.
A fair 2026 solar decision in Lewes needs three numbers side by side: the installed price (compare against $2.58 a watt), your utility's export rate under Delaware rules, and your actual daytime usage. Miss any one and the payback estimate on a sales slide is fiction.
What installed solar costs in 2026
| System size | Installed price (marketplace avg) | Notes |
|---|---|---|
| 6 kW | $15,480 | Small roof / low usage |
| 8 kW | $20,640 | Typical starter system |
| 10 kW | $25,800 | Family home with AC |
| 12 kW | $30,960 | Large home / EV charging |
| Home battery (optional) | $12,000-$16,000 | Backup power + self-consumption |

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The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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
| Rule | Delaware 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 incentive | Green 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 system | Exempt |
| Property tax on added home value | No 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.

Why only these platforms
Ask any homeowner whose installer went bankrupt: the money was not lost on the panels, it was lost on the workmanship warranty that evaporated. Before comparing prices, compare survival odds - years in business, local installations you can drive past, and manufacturer-backed workmanship coverage.
Solar lead generation is where most industry abuse lives, so this guide only links platforms that show you multiple named installers and let you walk away - never single-installer funnels or phone-blast forms. If a platform falls below that bar it gets removed from every page on this site.
| Platform | What you get | Background |
|---|---|---|
| EnergySage | Side-by-side bids from multiple installers | The largest U.S. solar marketplace; publishes its pricing data publicly |
| Modernize | Matched with vetted local installers | Established home-services network (QuinStreet); installers are screened |
Getting quotes in Lewes
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.
- Your last 12 months of electricity bills - sizing should follow real usage
- Roof age and type - reroofing after panels go up is expensive
- Your utility's export rate under Delaware rules - it decides the payback
- Whether you want backup power - that is a battery decision, priced separately
- Written itemization: hardware, labor, permits, and any financing dealer fee
Reading a Lewes roof honestly
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
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.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
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.
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.
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.
