What New York homeowners should check

New York City solar is shaped by limited roof area, shading from nearby buildings, rooftop mechanical equipment, and fire-access rules. Flat-roof attachment, waterproofing, structural capacity, and usable setbacks often matter more than raw panel efficiency.

Con Edison projects can involve detailed electrical and interconnection review. For co-ops, condos, and multifamily buildings, roof rights and building approval should be resolved before relying on a residential savings estimate.

At the state level, New York currently uses full retail net metering (transitioning to vder). A typical interconnection takes 8–20 weeks (con edison notably slower), but utility review and local permitting can extend that range. Check current rules before relying on a proposal's export-credit or installation-date assumptions.

What should I verify before signing a solar contract in New York?

Confirm that the quote names your actual utility, uses a recent electricity rate, includes measured shade and roof-condition findings, and explains who handles permits and interconnection. Ask the installer to separate guaranteed equipment and workmanship terms from estimated production, incentives, and savings.

Illustrative 4 peak sun hours, 14.08% production losses, 22.0 cents/kWh and $3.2/W. The retail-value ceiling assumes every kWh earns retail value; lower export credits reduce it. The cost/value ratio is not a full payback model and excludes repairs, financing and rate changes. No new Section 25D homeowner credit in 2026.
