What home solar costs in Old Tappan - 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 Old Tappan homeowner actually pays in 2026, what New Jersey still offers, and how to compare quotes without getting played.
Installed home solar for Old Tappan 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 - Old Tappan systems completed in 2026 get $0 from it.
Under New Jersey's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Old Tappan plus 12 surrounding towns within 40 km form one installer market of about 91,634 people - quotes should not vary much by town.
Old Tappan has about 6,342 residents, and every solar quote here is built from the same inputs: system size, roof complexity, and what your utility pays for exported power under New Jersey rules. The marketplace average runs about $2.58 a watt installed - quotes far above that deserve an explanation, not a signature.
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 Old Tappan is not the hardware - panels are commodities - but installer overhead, sales commissions, and New Jersey's export rules. That is where quotes win or lose.

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The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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 Jersey rules that decide your payback
| Rule | New Jersey status |
|---|---|
| Export compensation (net metering) | Full retail-rate net metering: homeowners receive full retail credit on their utility bill for every kWh their system produces over a 12-month annualized cycle, systems must be sized not to exceed the customer's annual electric needs, and any excess generation existing when a customer switches suppliers or changes their anniversary date is credited at the wholesale Locational Marginal Price rather than retail. |
| State incentive | Successor Solar Incentive (SuSI) Program - Administratively Determined Incentive (ADI) sub-program, which pays residential net-metered systems SREC-IIs for 15 years; the Board cut the residential rate from $85/MWh to $77/MWh for all registrations received on or after July 27, 2026, and opened a 300 MW residential block for Energy Year 2027 on June 1, 2026 (first-come, first-served until subscribed or June 1, 2027) |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
The residential ADI block is chronically oversubscribed - registrations ran ~5.2 MW/week in EY2026 and the Board had to move 35 MW from the non-residential segment in April 2026 to keep the residential block from closing early - so homeowners should confirm block capacity remains before signing.

Why only these platforms
The cheapest bid per watt is not the best bid. Panel warranties run 25 years, but the workmanship warranty dies with the installer - and the post-credit shakeout is closing solar companies every month in 2026. The best quote comes from the company that will still answer the phone in year five.
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 Old Tappan
Marketplace platforms collect bids from multiple NJ installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.
- 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 Jersey 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

Common questions
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.
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.
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 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.
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.
