Solar panels in Kissimmee, FL

Roofs in Kissimmee get about 1,738 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 Kissimmee solar system costs

A 19-panel system (7.6 kW) is about right for an average Kissimmee home using 10,800 kWh a year. It would produce roughly 11,227 kWh annually and offset 100% of that usage.

How we worked this out for Kissimmee

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

Step 6 matters more than it looks. Only 34% of what a system this size produces in Kissimmee is used the moment it is generated; the other 7,447 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 Kissimmee gets 1,738 sun hours

That figure comes from Google's analysis of real rooftops across Kissimmee — 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 Kissimmee reaches about 1,844 hours, roughly 6% better than typical.

When Kissimmee actually produces

Annual totals hide the thing that catches people out: 32% of Kissimmee's yearly sunlight arrives in May–July, and just 17% across November–January.

Output is unusually steady — only about 2.0× between Jun and Dec. Kissimmee 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 Kissimmee's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

How Kissimmee compares to the other 788 cities

What actually stands out about Kissimmee:

• Plenty of roof to work with. Typical roofs here fit around 109 panels — roughly 5× what an average home needs. Roof size will not be what limits your system in Kissimmee.
• Large roofs. At a median of 420 m², Kissimmee has the 24th-largest typical roof footprint we've measured.
