Solar panels in Amarillo, TX

Roofs in Amarillo get about 1,935 hours of usable sunlight a year — more than 92% 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 Amarillo solar system costs

A 17-panel system (6.8 kW) is about right for an average Amarillo home using 10,800 kWh a year. It would produce roughly 11,184 kWh annually and offset 100% of that usage.

How we worked this out for Amarillo

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

Step 6 matters more than it looks. Only 34% of what a system this size produces in Amarillo is used the moment it is generated; the other 7,404 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 — 8.0 years against the 8.2 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, 15.1¢/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 Amarillo gets 1,935 sun hours

That figure comes from Google's analysis of real rooftops across Amarillo — 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 Amarillo reaches about 2,042 hours, roughly 6% better than typical.

When Amarillo actually produces

Annual totals hide the thing that catches people out: 34% of Amarillo's yearly sunlight arrives in May–July, and just 15% across November–January.

Output is unusually steady — only about 2.5× between Jun and Dec. Amarillo is close enough to the equator that seasonal variation is mild, which makes sizing a system considerably more predictable.

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

How Amarillo compares to the other 788 cities

What actually stands out about Amarillo:

• Sunnier than the rest of Texas. Amarillo roofs get 10% more usable sunlight than the typical Texas city we've measured — statewide averages will understate what you can expect here.

Cities with almost the same sunlight

These are the closest matches to Amarillo's 1,935 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
