The best angle and direction for panels in Fargo
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,354 |
| Southeast | 94% | 1,273 |
| Southwest | 94% | 1,273 |
| East | 80% | 1,083 |
| West | 79% | 1,070 |
| North | 55% | 745 |
Face panels south and tilt them 44° for the most energy over a year. East and west roofs keep about 80% of that. A north-facing roof keeps 55%, which is rarely worth the money. Try other angles.
Where the sun goes over Fargo
The noon sun is lower in winter, which is why the best winter tilt (71°) is steeper than the best summer tilt (17°).
Fargo's homes
Fargo has 59,970 households. 43.7% own their home, and 23,476 of those owners live in single-family houses, the kind of home that usually gets rooftop solar.
The median home here was built in 1991. 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.
52.9% of homes heat with electricity and 41.1% with gas. Electric heat raises winter use, so size solar to your own bills rather than the state average.

Snow: NASA records about 19 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.
