The best angle and direction for panels in Provo
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,579 |
| Southeast | 95% | 1,500 |
| Southwest | 95% | 1,500 |
| East | 83% | 1,311 |
| West | 82% | 1,295 |
| North | 60% | 947 |
Face panels south and tilt them 37° for the most energy over a year. East and west roofs keep about 83% of that. A north-facing roof keeps 60%, which is rarely worth the money. Try other angles.
Where the sun goes over Provo
The noon sun is lower in winter, which is why the best winter tilt (65°) is steeper than the best summer tilt (10°).
Provo's homes
Provo has 34,022 households. 39.4% own their home, and 11,853 of those owners live in single-family houses, the kind of home that usually gets rooftop solar.
The median home here was built in 1983. 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.
22.9% of homes heat with electricity and 73.7% with gas. If you switch to a heat pump or an electric car, plan for more panels or leave room on the roof.
