The best angle and direction for panels in Sanford
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,458 |
| Southeast | 96% | 1,400 |
| Southwest | 96% | 1,400 |
| East | 87% | 1,268 |
| West | 86% | 1,254 |
| North | 69% | 1,006 |
Face panels south and tilt them 27° for the most energy over a year. East and west roofs keep about 87% of that. A north-facing roof keeps 69%, which is rarely worth the money. Try other angles.
Where the sun goes over Sanford
The noon sun is lower in winter, which is why the best winter tilt (52°) is steeper than the best summer tilt (1°).
Sanford's homes
Sanford has 24,875 households. 52% 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 1994. 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.
95.2% of homes heat with electricity and 2.7% with gas. Electric heat raises winter use, so size solar to your own bills rather than the state average.
