Solar panels in Fort Lauderdale, FL

Roofs in Fort Lauderdale get about 1,745 hours of usable sunlight a year — more than 77% 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 Fort Lauderdale solar system costs

A 19-panel system (7.6 kW) is about right for an average Fort Lauderdale home using 10,800 kWh a year. It would produce roughly 11,273 kWh annually and offset 100% of that usage.

How we worked this out for Fort Lauderdale

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

Step 6 matters more than it looks. Only 34% of what a system this size produces in Fort Lauderdale is used the moment it is generated; the other 7,493 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 — 8.8 years against the 9.1 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 Fort Lauderdale gets 1,745 sun hours

That figure comes from Google's analysis of real rooftops across Fort Lauderdale — 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 Fort Lauderdale reaches about 1,829 hours, roughly 5% better than typical.

The numbers behind this page

When Fort Lauderdale actually produces

Annual totals hide the thing that catches people out: 31% of Fort Lauderdale'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. Fort Lauderdale 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 Fort Lauderdale's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

Cities with almost the same sunlight

These are the closest matches to Fort Lauderdale's 1,745 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
