Solar panels in Davie, FL

Roofs in Davie get about 1,795 hours of usable sunlight a year — more than 82% 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 Davie solar system costs

A 18-panel system (7.2 kW) is about right for an average Davie home using 10,800 kWh a year. It would produce roughly 10,985 kWh annually and offset 100% of that usage.

How we worked this out for Davie

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

Step 6 matters more than it looks. Only 34% of what a system this size produces in Davie is used the moment it is generated; the other 7,205 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 — 8.5 years against the 8.7 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, 15.3¢/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 Davie gets 1,795 sun hours

That figure comes from Google's analysis of real rooftops across Davie — 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 Davie reaches about 1,814 hours, roughly 1% better than typical.

When Davie actually produces

Annual totals hide the thing that catches people out: 31% of Davie's yearly sunlight arrives in May–July, and just 18% across November–January.

Output is unusually steady — only about 1.8× between Jun and Dec. Davie 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 Davie's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

How Davie compares to the other 788 cities

What actually stands out about Davie:

• Unusually open roofs. Only 1% of available sunlight is lost to obstruction in Davie — better than all but 18 of the 788 cities measured. Most roofs here get close to their theoretical maximum.
• Plenty of roof to work with. Typical roofs here fit around 98 panels — roughly 5× what an average home needs. Roof size will not be what limits your system in Davie.

Cities with almost the same sunlight

These are the closest matches to Davie's 1,795 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
