New York solar guide
DIY solar in New York: incentives, sizing, and the off-grid angle
New York has one of the most generous state solar credits in the country: 25% of system cost, capped at $5,000. Combined with the federal 26% credit, that's effectively 51% off a $20,000 install for the first $20k of system cost. Sales tax exemption on equipment and property tax exemption on PV systems stack on top.
The catch: net metering was restructured to VDER (Value of Distributed Energy Resources), which compensates exports at location-specific rates rather than full retail. For most residential setups outside NYC, VDER produces approximately the same financial outcome as old-school net metering — but the math is more complex.

25% of system cost, capped at $5,000 (NY State Solar Tax Credit).
Your panels, batteries, and controllers ship sales-tax-free.
Adding solar doesn't bump your assessed value.
Value of Distributed Energy Resources (VDER) compensates exports at varying rates by location; equivalent to net metering for most residential setups.
No SREC revenue available in this state.
Used to size your array — more sun hours = fewer panels needed for the same output.
Stricter permitting in NYC and Long Island; upstate is generally more DIY-friendly.
DIY install angle in New York
New York allows homeowner electrical permits in most municipalities, but NYC and Long Island have stricter requirements. NYC requires a licensed electrician for grid-tie connections and stamped engineering for all installs. Upstate counties (Albany, Erie, Onondaga) are generally DIY-friendly with documented homeowner paths.
The NYC apartment/condo question: rooftop solar on multi-family buildings in NYC works but requires building-level approval and is typically a building-wide investment rather than an individual homeowner DIY project. The economics still pencil out in many cases given Con Edison's high rates.
Upstate New York DIY: rural and small-town upstate is the heartland of NY DIY solar. Cabin and homestead installs are particularly common around the Adirondacks, Finger Lakes, and Catskills. Most counties require just a permit fee, electrical inspection, and utility interconnection paperwork.
NY-Sun program: NYSERDA's NY-Sun incentive provides additional per-watt payments for new solar installs. Most installers handle the paperwork; DIY builders apply directly through NYSERDA. The incentive amount varies by region and degrades as the program block fills.
Sizing for New York sun
New York averages 4.1 peak sun hours/day, with Long Island averaging 4.3, NYC at 4.1, and upstate (Albany, Syracuse, Buffalo) at 3.8. The Adirondacks get slightly less due to terrain shading and cloud frequency.
Lake-effect winter cloudy stretches: Buffalo and Watertown can see weeks of December-January cloud cover. Off-grid systems in lake-effect snow belts need significantly oversized arrays (50%+ above average sizing) and substantial battery autonomy (3-5 days) to ride through the worst weeks.
The fall foliage tradeoff: deciduous tree shading is a real factor for many NY rural and suburban properties. A site that's clear in winter (no leaves) may be partially shaded for 6 months of peak sun. Site selection matters more in NY than in arid Western states.
Battery sizing in upstate NY: for winter-heavy off-grid use, plan for at least 3 days of autonomy and oversize the array 30-50% to handle the December cloud stretches. The newer 48V LFP packs in the 15-25 kWh range work well for typical NY cabin and homestead setups.
