The best angle and direction for panels in Norman
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,507 |
| Southeast | 96% | 1,447 |
| Southwest | 95% | 1,432 |
| East | 84% | 1,266 |
| West | 83% | 1,251 |
| North | 61% | 919 |
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 61%, which is rarely worth the money. Try other angles.
Where the sun goes over Norman
The noon sun is lower in winter, which is why the best winter tilt (59°) is steeper than the best summer tilt (6°).
Norman's homes
Norman has 52,748 households. 53.3% own their home, and 26,439 of those owners live in single-family houses, the kind of home that usually gets rooftop solar.
The median home here was built in 1988. 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.
44.4% of homes heat with electricity and 52.8% with gas. If you switch to a heat pump or an electric car, plan for more panels or leave room on the roof.

Snow: NASA records about 6 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.
