What home solar costs in Lake Success - 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 Lake Success homeowner actually pays in 2026, what New York still offers, and how to compare quotes without getting played.
Installed home solar for Lake Success 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 - Lake Success systems completed in 2026 get $0 from it.
Under New York's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Lake Success plus 12 surrounding towns within 40 km form one installer market of about 66,361 people - quotes should not vary much by town.
Solar pricing is unusually transparent if you know where to look: marketplace data puts the U.S. average at about $2.58 per watt installed. What varies in Lake Success is not the hardware - panels are commodities - but installer overhead, sales commissions, and New York's export rules. That is where quotes win or lose.
The single biggest change for Lake Success homeowners in 2026: the federal 30% tax credit is gone. A $31,000 system that effectively cost $21,700 in 2025 now costs the full $31,000. That does not automatically make solar a bad buy in New York - but it makes the state rules below matter far more.
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The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.
New York rules that decide your payback
| Rule | New York status |
|---|---|
| Export compensation (net metering) | Traditional (Phase One) net metering is still available for residential rooftop solar up to 25 kW - the customer is billed only for net electricity consumed and surplus kWh roll forward as credits - but any system interconnected on or after January 1, 2022 also pays a monthly Customer Benefit Contribution (CBC) charge based on DC nameplate size (2026 residential rates $0.97-$1.67 per kW-month depending on utility), while larger and front-of-meter projects are compensated under the VDER Value Stack instead. |
| State incentive | NY State Solar Energy System Equipment Credit (25% of qualified expenditures, capped at $5,000, non-refundable with 5-year carryover) plus the NY-Sun MW Block incentive administered by NYSERDA (per-watt, varies by region and block; Upstate Residential Block 14 was the active residential block as of 2026) |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
The RPTL 487 property tax exemption runs only 15 years and each county, city, town, village and school district may individually opt out of it, so the exemption is not guaranteed everywhere; New York City separately runs its own solar property tax abatement program.

Why only these platforms
In solar, the expensive mistake is rarely the price per watt - it is the wrong contract: a 20-25 year lease with an escalator clause, financing with a buried dealer fee, or an oversized system in a state that pays pennies for exports. A slightly higher bid from an installer with a decade of local history is usually the cheap option.
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 Lake Success
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 New York 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 Lake Success 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
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 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.
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.
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.
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.
