What a typical Charlotte solar system costs
A 21-panel system (8.4 kW) is about right for an average Charlotte home using 10,800 kWh a year. It would produce roughly 11,146 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,246 | $6,384 | $560 | 11.4 yrs |
| 12 panels | 4.8 kW | 6,369 | $9,576 | $841 | 11.4 yrs |
| 16 panels | 6.4 kW | 8,492 | $12,768 | $1,121 | 11.4 yrs |
| 20 panels | 8 kW | 10,615 | $15,960 | $1,401 | 11.4 yrs |
| 26 panels | 10.4 kW | 13,799 | $20,748 | $1,525 | 13.6 yrs |
How we worked this out for Charlotte
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Charlotte rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,561 sun hrs × 0.85 system losses |
531 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 531 kWh per panel |
21 panels |
| 3 | System size 21 panels × 400W |
8.40 kW |
| 4 | Annual production 8.40 kW × 1,561 hrs × 0.85 |
11,146 kWh/yr |
| 5 | Installed cost 8,400 W × $2.85 per watt, then −30% federal credit |
$16,758 |
| 6 | Annual saving 3,780 kWh used as generated × 13.2¢ + 7,366 kWh exported × 13.2¢ |
$1,437/yr |
| 7 | Payback $16,758 ÷ $1,437 per year |
11.7 years |
Step 6 matters more than it looks. Only 34% of what a system this size produces in Charlotte is used the moment it is generated; the other 7,366 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 — 11.4 years against the 11.7 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, 13.2¢/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 Charlotte gets 1,561 sun hours
That figure comes from Google's analysis of real rooftops across Charlotte — 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 Charlotte reaches about 1,652 hours, roughly 6% better than typical.

When Charlotte actually produces
Annual totals hide the thing that catches people out: 34% of Charlotte's yearly sunlight arrives in May–July, and just 15% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 79 | |
| Feb | 101 | |
| Mar | 128 | |
| Apr | 156 | |
| May | 174 | |
| Jun | 181 | |
| Jul | 177 | |
| Aug | 162 | |
| Sep | 138 | |
| Oct | 109 | |
| Nov | 84 | |
| Dec | 73 |
Output is unusually steady — only about 2.5× between Jun and Dec. Charlotte 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 Charlotte's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

Charlotte solar questions
How many solar panels do I need in Charlotte?
About 21 panels for an average home using 10,800 kWh a year. Charlotte roofs get 1,561 usable sun hours, so each 400W panel produces roughly 531 kWh annually. A typical Charlotte roof fits about 87 panels, so roof space is unlikely to be your limit.
Is solar worth it in Charlotte?
At 13.2¢/kWh and 1,561 sun hours, a typical system pays for itself in about 11.7 years and returns roughly $19,167 over a 25-year panel life. That is slower than average, so compare several quotes before committing. Exported power earns full retail credit here.
How much do solar panels cost in Charlotte?
A 8.4 kW system costs about $23,940 before incentives and $16,758 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.
