Solar panels in York, PA

Roofs in York get about 1,353 hours of usable sunlight a year — less than 76% of the cities we've measured. Here's what that means in cost, savings and payback, using real rooftop data rather than a national average.

What a typical York solar system costs

A 24-panel system (9.6 kW) is about right for an average York home using 10,800 kWh a year. It would produce roughly 11,040 kWh annually and offset 100% of that usage.

How we worked this out for York

Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from York rooftops.

Step 6 matters more than it looks. Only 34% of what a system this size produces in York is used the moment it is generated; the other 7,260 kWh is exported and credited one-for-one under net metering. Because exports here are credited at or near retail, that split changes the payback very little — 9.6 years against the 9.7 we show. In places where exports pay a fraction of retail the same split moves payback by years, which is why we model it explicitly rather than assuming.

Assumptions: 400W panels, 15% system losses (inverter, wiring, heat, soiling), $2.85/W installed, 10,800 kWh typical annual household use, 18.1¢/kWh electricity. Change any of those and every figure above moves — which is exactly why a single national "solar costs X" number is misleading.

Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.

Why York gets 1,353 sun hours

That figure comes from Google's analysis of real rooftops across York — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in York reaches about 1,596 hours, roughly 18% better than typical.

When York actually produces

Annual totals hide the thing that catches people out: 36% of York's yearly sunlight arrives in May–July, and just 13% across November–January.

York produces about 3.0× as much in Jun as in Dec — a normal mid-latitude swing. Expect real winter shortfall and summer surplus rather than steady year-round output.

The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at York's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

How York compares to the other 788 cities

What actually stands out about York:

• Shading is a real problem here. York loses 15% of its potential sunlight to trees, chimneys and neighbouring buildings — the 17th-worst of the 788 cities measured. Panel placement matters more here than in most places, and a roof survey is worth more than a phone quote.

Cities with almost the same sunlight

These are the closest matches to York's 1,353 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
