The best angle and direction for panels in Shreveport
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,365 |
| Southeast | 96% | 1,310 |
| Southwest | 96% | 1,310 |
| East | 86% | 1,174 |
| West | 85% | 1,160 |
| North | 66% | 901 |
Face panels south and tilt them 30° for the most energy over a year. East and west roofs keep about 86% of that. A north-facing roof keeps 66%, which is rarely worth the money. Try other angles.
Where the sun goes over Shreveport
The noon sun is lower in winter, which is why the best winter tilt (56°) is steeper than the best summer tilt (3°).
Shreveport's homes
Shreveport has 75,996 households. 53.3% own their home, and 39,108 of those owners live in single-family houses, the kind of home that usually gets rooftop solar.
The median home here was built in 1973. 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.
54.8% of homes heat with electricity and 43.2% with gas. Electric heat raises winter use, so size solar to your own bills rather than the state average.
