Solar Panel Cost in Westchester County, NY: A Step-by-Step Breakdown
If you’ve asked a few different installers for a quote, you’ve probably gotten a few different numbers — with no real explanation of what’s driving them. Here’s how solar panel cost actually breaks down for a Westchester County homeowner, one step at a time.
Step 1: Start With Your Con Edison Bill
Before you can price out panels, you need a baseline — and that baseline is your actual electric bill. Westchester homeowners pay some of the highest electricity rates in the country: an average of 38¢ per kWh, compared to a national average of roughly 14¢. Look closely at your bill and you’ll see it’s really two charges stacked together: a supply charge for the electricity itself, and a delivery charge for getting it to your house. In Con Edison territory, the delivery charge typically runs about twice the supply charge — meaning roughly two-thirds of what you pay each month has nothing to do with how much power you actually use.
Con Edison has also raised rates by about 8% a year on average. That means the number on your bill today isn’t the number you should be pricing solar against.

Step 2: Determine the System Size You Need
Solar panel cost scales directly with system size, measured in kilowatts (kW) of capacity. Sizing depends on your household’s annual usage, roof space and orientation, and how much of your bill you want to offset. Westchester gets strong sun exposure for solar production — around 9 peak sun hours a day in summer and about 5 in winter — so a properly sized system can realistically offset 80–100% of a typical household’s annual electricity use. A smaller home with modest usage might only need a 6 kW system, while a larger household with electric heat or an EV might need 10 kW or more. This is also why “solar panel cost” isn’t one number — it’s a range that only makes sense once your usage and roof are factored in.
Step 3: Understand the Base Cost Before Incentives
Before any incentives are applied, most Westchester County homeowners see proposals in the range of roughly $18,000 to $40,000 for a full residential system, depending on size and roof complexity. Here’s a general idea of how that scales:
| System Size | Approx. Panels | Est. Cost Before Incentives |
|---|---|---|
| 6 kW | 14–16 panels | $18,000 – $21,000 |
| 8 kW | 19–21 panels | $24,000 – $28,000 |
| 10 kW | 24–26 panels | $30,000 – $34,000 |
| 12 kW | 28–30 panels | $36,000 – $40,000 |
These are general estimates, not a quote — final pricing depends on a site-specific survey of your roof, shading, and electrical panel.
Step 4: Subtract New York’s Solar Incentives
This is the step that explains why the number on a quote isn’t the number you actually pay. New York stacks several incentives that meaningfully lower solar panel cost for homeowners:
- NY-Sun / NYSERDA Megawatt Block Rebate — a per-watt rebate your installer applies automatically, reducing the upfront system price.
- NY State Solar Tax Credit — 25% of system cost, up to $5,000, credited directly (not just deducted) from what you owe in state taxes.
- 15-Year Property Tax Exemption — the added home value from your solar system is exempt from property tax assessment for 15 years.
- Net Metering — excess electricity your system produces is credited back at the full retail rate (38¢/kWh in Con Edison territory), lowering your effective cost of ownership over time.
If you purchase your system with cash or a loan, the federal solar tax credit is also available on top of New York’s incentives. It generally does not apply if you choose a lease or PPA — so it’s worth asking any installer which ownership structure they’re quoting you.
Step 5: Compare Financing Options — the Real Monthly Cost
The sticker price matters less than what you actually pay each month. Many Westchester homeowners go solar with $0 out of pocket through financing structured so the monthly loan payment lands below their current Con Edison bill from day one. After switching, most households see their monthly grid-electricity bill drop from around $300 to roughly $150–$180 — a 40–50% reduction — plus a small basic service charge of about $20/month to remain connected to the grid. That charge isn’t a penalty for cloudy days; it’s simply the cost of staying tied to the grid, and net metering credits from your sunniest months typically cover the gap during overcast stretches.
Put together, that’s the real answer to “what does solar cost in Westchester County”: a base system price that gets meaningfully reduced by New York’s incentives, financed in a way that’s designed to cost less per month than what you’re already paying Con Edison.
