Residential Solar Buyer's Guide (Rooftop and Community)

Equipment type: Residential solar (rooftop and community subscriptions) Last reviewed: May 27, 2026 Source quality: Secondary

What this equipment is

Residential solar in New York comes in two physical forms: panels on your own roof (or on a ground-mount frame on your property) and a subscription share of a remote community solar farm. Both produce electricity that offsets your utility bill. They differ in who owns the hardware, what you pay up front, and what happens at the end of the deal.

Rooftop solar splits into three ownership models. Direct purchase means you pay cash or take a loan, you own the system, and you keep every incentive (NY-Sun rebate, the New York State tax credit, depreciation does not apply to residential). Leased systems mean a third party owns the panels on your roof and you pay a fixed monthly amount for them. Power purchase agreements (PPAs) mean a third party owns the panels and you pay per kilowatt-hour produced, usually at a rate below the utility's. In leased and PPA structures, the tax credits and rebates go to the system owner, not you.

Community solar is the fourth model. You do not put anything on your roof. You subscribe to a share of a solar farm somewhere else in your utility territory and receive credits on your utility bill for your share of the production. Community solar is the right answer when your roof is shaded, north-facing, too old, or you rent. Termination terms vary widely by provider, so the contract matters more than the marketing.

Programs that apply

A New York solar install can stack several incentives at once. The combination depends on ownership model, utility territory, and household income.

  • NY-Sun. The main state rebate program for rooftop and ground-mount residential solar. Rebate is paid through the installer at install time and varies by region and block.
  • NY-Sun Community Solar. The state's community solar program. You subscribe through a participating provider rather than receiving a hardware install.
  • NY State Solar Tax Credit. A state income tax credit on residential rooftop systems you own (does not apply to leases, PPAs, or community subscriptions).
  • Solar for All. An income-qualified community solar program that delivers bill credits at no subscription cost to participating households.
  • NYSERDA Residential Financing. State-backed loan products for homeowners financing the unrebated portion of a rooftop system.
  • Federal Residential Energy Credits: Program Ended. The federal §25D Residential Clean Energy Credit expired December 31, 2025. New rooftop installs placed in service in 2026 and later do not qualify for the federal credit. This is the single biggest change in residential solar economics from 2025 to 2026 and is the most common point of confusion.

Sequencing your project

The order of operations protects you from buying the wrong system or buying it before the house is ready.

  1. Confirm your roof condition. Asphalt shingle roofs over about 15 years old should be replaced before the panels go on. Removing panels to reroof later costs thousands. Get a roofer's opinion in writing before signing a solar contract.
  2. Check your electrical panel capacity. A standard 100-amp panel may not have room for a solar backfeed breaker without upgrades. A licensed electrician can confirm whether your panel needs a service upgrade. Panel upgrades are sometimes eligible for separate incentives; ask about that during quoting.
  3. Run your address through the NY-Sun rebate finder. Start at nyserda.ny.gov/All-Programs/NY-Sun and confirm your block status (rebate availability moves through tranches that step down as capacity fills). The finder also lists participating contractors in your area.
  4. Get at least two quotes from NYSERDA-eligible installers. Each quote should specify system size in kilowatts (kW), annual production estimate in kilowatt-hours (kWh), panel make and model, inverter type, and a clearly labeled net cost after the NY-Sun rebate. Compare per-watt installed cost across quotes.
  5. Decide on ownership model. If you have tax liability and cash or access to financing, direct purchase keeps every incentive in your pocket. If you have no roof or a bad roof, a community solar subscription is the cleaner path. Lease and PPA terms run 20 to 25 years and bind the next owner of the house, so read those contracts carefully.
  6. Permitting and interconnection. Your installer handles building permits, electrical permits, and the utility interconnection application. Interconnection approval can take weeks; this is the slowest step.
  7. Install and PTO. After install, your utility issues Permission to Operate (PTO) before you are allowed to flip the system on. Production credits begin at PTO, not at install completion.

What to look for in equipment

A handful of specs decide whether the system performs and stays compliant.

  • System size in kW. A right-sized system covers somewhere between 80 and 110 percent of your annual electricity use based on the previous 12 months of bills. Going much larger wastes panel space, since residential net metering credits roll over but are reconciled annually and excess production is paid out at a low rate.
  • Panel wattage. Module wattages have climbed steadily; residential modules in the 400 to 450 watt range are common now. Higher-wattage modules let you reach the same system size with fewer panels and less roof area used.
  • Inverter type. String inverters convert DC to AC for a whole string of panels at once and are cheaper but underperform when any panel in the string is shaded. Microinverters sit on each panel and handle shade and partial-failure conditions better. Hybrid inverters that integrate battery support are a third category worth asking about if storage is on your roadmap.
  • Module-level shutdown. The National Electrical Code 690.12 rapid shutdown requirement applies to residential rooftop solar in New York. Microinverters and DC optimizers both satisfy this code; a plain string inverter alone does not. Confirm your install meets 690.12.
  • Production warranty vs. equipment warranty. Panels typically carry a 25-year production warranty (guaranteed output as a percentage of nameplate over time) and a separate 10- to 25-year equipment warranty (against physical defect). Inverters typically carry shorter warranties, often 10 to 12 years for string inverters and 25 years for microinverters.

What to ask your contractor

  • Are you a NYSERDA-eligible NY-Sun installer, and what is your installer ID?
  • What is the proposed system size in kW, and what annual production in kWh does that translate to for my roof orientation and shading?
  • What percentage of my last 12 months of usage does this size cover?
  • String inverter, microinverters, or DC optimizers, and how does that choice handle the shaded section of my roof?
  • Does the install meet NEC 690.12 module-level rapid shutdown, and how?
  • Will the rebate be processed at install time and deducted from my invoice, or will I be reimbursed separately?
  • For a PPA or lease quote: what is the escalator clause, what happens if I sell the house, and what is the buyout schedule?
  • For community solar: what is the cancellation policy, and how is my bill credit calculated against my actual usage?

Common pitfalls

  • Assuming the federal credit still applies. The §25D credit ended December 31, 2025. Some installer marketing collateral has not been updated and still quotes a 30 percent federal credit. Confirm in writing what credits actually apply to your install date.
  • Working with an uncertified installer. NY-Sun rebates are paid only through eligible installers on the NYSERDA list. An out-of-network contractor offering a lower sticker price often costs more after the lost rebate.
  • Oversized system. A 12 kW system on a house that uses 8,000 kWh per year wastes roof space and money, since excess generation reconciles annually at a low avoided-cost rate.
  • Long-term PPA traps. A 25-year PPA with a 2.9 percent annual escalator can outpace utility rates and lock you into above-market electricity by year 15. Read the escalator clause and the transferability terms before signing.
  • Old roof under new panels. Discovering you need a reroof three years into a 25-year install is a five-figure mistake. Reroof first.
  • Skipping interconnection delays in your planning. Utility interconnection review can run 4 to 12 weeks. Do not assume install day equals turn-on day.
