The best angle and direction for panels in Lynn
| Roof faces (6/12 pitch) | Output vs south | kWh per kW |
|---|---|---|
| South | 100% | 1,266 |
| Southeast | 95% | 1,203 |
| Southwest | 95% | 1,203 |
| East | 82% | 1,038 |
| West | 81% | 1,025 |
| North | 59% | 747 |
Face panels south and tilt them 37° for the most energy over a year. East and west roofs keep about 82% of that. A north-facing roof keeps 59%, which is rarely worth the money. Try other angles.
Where the sun goes over Lynn
The noon sun is lower in winter, which is why the best winter tilt (63°) is steeper than the best summer tilt (12°).
Lynn's homes
Lynn has 36,414 households. 48.1% own their home, and 12,596 of those owners live in single-family houses, the kind of home that usually gets rooftop solar.
The median home here was built in 1946. 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.
21.5% of homes heat with electricity and 56.6% with gas. If you switch to a heat pump or an electric car, plan for more panels or leave room on the roof.
