The Short Answer
Yes. Westchester County is one of the best markets for residential solar in the country. The combination of high electricity rates ($0.33/kWh on Con Edison), strong state incentives, and excellent net metering means most homeowners see full payback in 5-7 years on a system that lasts 25-30 years.
What Does Solar Cost in Westchester?
A typical residential solar installation in Westchester ranges from $20,000 to $35,000 before incentives, depending on system size. Most homes need a 7-10 kW system to offset 80-90% of their electricity usage. After the NY State 25% tax credit (up to $5,000) and NYSERDA incentives, the effective cost drops to $15,000-$28,000. Per-watt pricing in Westchester averages $3.00-$3.50 installed, which is competitive for the Northeast.
The Savings Math
A Westchester homeowner paying $300/month to Con Edison ($3,600/year) can typically offset 80-90% of that with solar. At $3,000/year in savings and an after-incentive cost of $22,000, the payback period is roughly 7.3 years. After payback, that is $3,000/year in pure savings for the remaining 18-23 years of the system warranty. Over 25 years, total savings typically exceed $50,000.
What About Battery Storage?
Battery storage adds $10,000-$15,000 per unit but unlocks TOU Rate III optimization. Con Edison peak rates run roughly 7.6x higher than off-peak. A battery charges during cheap off-peak hours ($0.05/kWh) and discharges during expensive peak hours (8AM-12AM weekdays). This arbitrage can add $800-$1,200/year in additional savings. NYSERDA offers a battery storage rebate of $250/kWh in Con Edison territory (approximately $3,375 for a standard 13.5 kWh unit), reducing the out-of-pocket cost significantly.
The 2026 Incentive Landscape
New York State offers a 25% solar tax credit up to $5,000. NYSERDA provides battery storage rebates of $250/kWh in Con Edison territory. A 15-year property tax exemption protects homeowners from increased assessments due to solar. Sales tax exemption applies to all solar equipment purchases. Net metering through Con Edison and NYSEG VDER credits allows homeowners to sell excess production back to the grid. The federal 30% residential ITC expired December 31, 2025, making state-level incentives the primary driver of solar economics in 2026.
Who Should NOT Go Solar?
Solar may not make sense if your roof is heavily shaded, needs replacement within 5 years, or faces primarily north. Homeowners with very low electricity bills (under $100/month) may find the payback period too long. Renters and condo owners typically cannot install rooftop solar, though community solar options exist.
