The number that decides whether solar pays in Asheville is what your utility pays for the power you send back. Duke Energy Carolinas: new customers get a Net Metering Bridge or time-of-use rider with exports at avoided cost. Under full payback is about 14.3 yrs. Under net billing it is about 23.2 yrs, because only the ~43% of solar a typical home uses as it is made saves the full retail price.
Cash purchase, prices rising 2.5% a year, panels losing 0.5% a year, $25/kW a year for upkeep. No federal credit for homeowner-owned systems.

The best angle and direction for panels in Asheville
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,370 |
| Southeast | 96% | 1,315 |
| Southwest | 95% | 1,302 |
| East | 84% | 1,151 |
| West | 83% | 1,137 |
| North | 62% | 849 |
Face panels south and tilt them 34° for the most energy over a year. East and west roofs keep about 84% of that. A north-facing roof keeps 62%, which is rarely worth the money. Try other angles.
Where the sun goes over Asheville
The noon sun is lower in winter, which is why the best winter tilt (59°) is steeper than the best summer tilt (6°).
Asheville's homes
Asheville has 37,394 households. 51.9% own their home, and 17,460 of those owners live in single-family houses, the kind of home that usually gets rooftop solar.
The median home here was built in 1982. Many roofs that age are due for replacement. Replace the roof first, then add solar: taking panels off and putting them back later costs thousands.
63.2% of homes heat with electricity and 28.5% with gas. Electric heat raises winter use, so size solar to your own bills rather than the state average.

Snow: NASA records about 9 cm of snow on the ground here in an average January. Covered panels make little until it slides off, and these figures (like PVWatts') don't subtract that.
