What a typical Boca Raton solar system costs
A 18-panel system (7.2 kW) is about right for an average Boca Raton home using 10,800 kWh a year. It would produce roughly 10,851 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,823 | $6,384 | $738 | 8.7 yrs |
| 12 panels | 4.8 kW | 7,234 | $9,576 | $1,107 | 8.7 yrs |
| 16 panels | 6.4 kW | 9,645 | $12,768 | $1,476 | 8.7 yrs |
| 20 panels | 8 kW | 12,056 | $15,960 | $1,700 | 9.4 yrs |
| 26 panels | 10.4 kW | 15,673 | $20,748 | $1,839 | 11.3 yrs |
How we worked this out for Boca Raton
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Boca Raton rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,773 sun hrs × 0.85 system losses |
603 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 603 kWh per panel |
18 panels |
| 3 | System size 18 panels × 400W |
7.20 kW |
| 4 | Annual production 7.20 kW × 1,773 hrs × 0.85 |
10,851 kWh/yr |
| 5 | Installed cost 7,200 W × $2.85 per watt, then −30% federal credit |
$14,364 |
| 6 | Annual saving 3,780 kWh used as generated × 15.3¢ + 7,071 kWh exported × 15.3¢ |
$1,654/yr |
| 7 | Payback $14,364 ÷ $1,654 per year |
8.7 years |
Step 6 matters more than it looks. Only 35% of what a system this size produces in Boca Raton is used the moment it is generated; the other 7,071 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 — 8.7 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 Boca Raton gets 1,773 sun hours
That figure comes from Google's analysis of real rooftops across Boca Raton — 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 Boca Raton reaches about 1,808 hours, roughly 2% better than typical.

When Boca Raton actually produces
Annual totals hide the thing that catches people out: 31% of Boca Raton's yearly sunlight arrives in May–July, and just 18% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 106 | |
| Feb | 126 | |
| Mar | 149 | |
| Apr | 170 | |
| May | 181 | |
| Jun | 185 | |
| Jul | 182 | |
| Aug | 173 | |
| Sep | 156 | |
| Oct | 133 | |
| Nov | 111 | |
| Dec | 100 |
Output is unusually steady — only about 1.8× between Jun and Dec. Boca Raton 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 Boca Raton's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

What actually stands out about Boca Raton:
- Unusually open roofs. Only 2% of available sunlight is lost to obstruction in Boca Raton — better than all but 65 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 137 panels — roughly 7× what an average home needs. Roof size will not be what limits your system in Boca Raton.
- Large roofs. At a median of 428 m², Boca Raton has the 22nd-largest typical roof footprint we've measured.

Boca Raton solar questions
How many solar panels do I need in Boca Raton?
About 18 panels for an average home using 10,800 kWh a year. Boca Raton roofs get 1,773 usable sun hours, so each 400W panel produces roughly 603 kWh annually. A typical Boca Raton roof fits about 137 panels, so roof space is unlikely to be your limit.
Is solar worth it in Boca Raton?
At 15.3¢/kWh and 1,773 sun hours, a typical system pays for itself in about 8.7 years and returns roughly $26,995 over a 25-year panel life. That is a solid return, and it improves further if electricity prices rise. Exported power earns full retail credit here.
How much do solar panels cost in Boca Raton?
A 7.2 kW system costs about $20,520 before incentives and $14,364 after the 30% federal tax credit. That works out near $2.85 per watt installed. Roof pitch, shading, electrical panel upgrades and equipment choice move the price most, which is why quotes for the same house can differ by thousands.
