Solar panels in Charlottesville, VA
Roofs in Charlottesville get about 1,396 hours of usable sunlight a year — less than 70% 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 Charlottesville solar system costs
A 23-panel system (9.2 kW) is about right for an average Charlottesville home using 10,800 kWh a year. It would produce roughly 10,917 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,797 | $6,384 | $539 | 11.8 yrs |
| 12 panels | 4.8 kW | 5,696 | $9,576 | $809 | 11.8 yrs |
| 16 panels | 6.4 kW | 7,594 | $12,768 | $1,078 | 11.8 yrs |
| 20 panels | 8 kW | 9,493 | $15,960 | $1,348 | 11.8 yrs |
| 26 panels | 10.4 kW | 12,341 | $20,748 | $1,588 | 13.1 yrs |
How we worked this out for Charlottesville
Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Charlottesville rooftops.
| # | Step | Result |
|---|---|---|
| 1 | What one panel makes here 400W ÷ 1000 × 1,396 sun hrs × 0.85 system losses |
475 kWh/yr |
| 2 | Panels needed to cover typical usage 10,800 kWh ÷ 475 kWh per panel |
23 panels |
| 3 | System size 23 panels × 400W |
9.20 kW |
| 4 | Annual production 9.20 kW × 1,396 hrs × 0.85 |
10,917 kWh/yr |
| 5 | Installed cost 9,200 W × $2.85 per watt, then −30% federal credit |
$18,354 |
| 6 | Annual saving 3,780 kWh used as generated × 14.2¢ + 7,137 kWh exported × 14.2¢ |
$1,538/yr |
| 7 | Payback $18,354 ÷ $1,538 per year |
11.9 years |
Step 6 matters more than it looks. Only 35% of what a system this size produces in Charlottesville is used the moment it is generated; the other 7,137 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 — 11.8 years against the 11.9 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, 14.2¢/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 Charlottesville gets 1,396 sun hours
That figure comes from Google's analysis of real rooftops across Charlottesville — 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 Charlottesville reaches about 1,550 hours, roughly 11% better than typical.

When Charlottesville actually produces
Annual totals hide the thing that catches people out: 35% of Charlottesville's yearly sunlight arrives in May–July, and just 14% across November–January.
| Month | Sun hrs | Share of year |
|---|---|---|
| Jan | 66 | |
| Feb | 87 | |
| Mar | 114 | |
| Apr | 141 | |
| May | 160 | |
| Jun | 167 | |
| Jul | 163 | |
| Aug | 148 | |
| Sep | 123 | |
| Oct | 95 | |
| Nov | 71 | |
| Dec | 60 |
Charlottesville produces about 2.8× as much in Jun as in Dec — a normal mid-latitude swing. Expect real winter shortfall and summer surplus rather than steady year-round output.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Charlottesville's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
How Charlottesville compares to the other 788 cities
| Measure | Charlottesville | Rank of 788 |
|---|---|---|
| Usable sunlight | 1,396 hrs | 551st |
| Sunlight lost to shade | 10% | 77th most |
| Median roof size | 132 m² | 609th largest |
| Electricity rate | 14.2¢ | 570th highest |
| Payback | 11.9 yrs | 520th fastest |
| Grid carbon | 649 kg/MWh | 369th dirtiest |
What actually stands out about Charlottesville:
- Shading is a real problem here. Charlottesville loses 10% of its potential sunlight to trees, chimneys and neighbouring buildings — the 77th-worst of the 788 cities measured. Panel placement matters more here than in most places, and a roof survey is worth more than a phone quote.
- Dimmer than the rest of Virginia. Charlottesville roofs get 9% less usable sunlight than the typical Virginia city we've measured — statewide averages will overstate what you can expect here.
- Older imagery. Google's aerial capture of Charlottesville dates from 2016. Tree growth and new construction since then are not reflected.
Cities with almost the same sunlight
These are the closest matches to Charlottesville's 1,396 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.

Charlottesville solar questions
How many solar panels do I need in Charlottesville?
About 23 panels for an average home using 10,800 kWh a year. Charlottesville roofs get 1,396 usable sun hours, so each 400W panel produces roughly 475 kWh annually. A typical Charlottesville roof fits about 46 panels, so roof space is unlikely to be your limit.
Is solar worth it in Charlottesville?
At 14.2¢/kWh and 1,396 sun hours, a typical system pays for itself in about 11.9 years and returns roughly $20,090 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 Charlottesville?
A 9.2 kW system costs about $26,220 before incentives and $18,354 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.
