Solar Panel Recommendations for Baltimore
- Fixed mount: Set your panels at 37.3° tilt, facing South (180° azimuth).
- Seasonal adjustment: Tilt to 24.3° in summer and 54.3° in winter for up to 15% more annual energy.
- Monthly adjustment: Adjust tilt each month using the table above for maximum year-round production.
Solar in Charm City's Mid-Atlantic Climate
Baltimore receives approximately 4-4.5 peak sun hours daily with a mid-Atlantic climate that provides a strong foundation for residential solar. The city's location at 39.3°N produces four distinct seasons with warm summers and cool winters. Maryland has developed some of the most supportive solar policies on the East Coast.
Maryland offers one of the strongest SREC (Solar Renewable Energy Certificate) markets in the country, providing an additional revenue stream beyond net metering savings. BGE (Baltimore Gas and Electric) offers net metering for residential customers. The combination of SREC revenue and the federal ITC makes Baltimore one of the more attractive solar markets in the mid-Atlantic region.
The city's dense urban environment includes many rowhomes with flat or low-slope roofs well-suited for solar arrays. Older residential neighborhoods may have mature tree shading that requires assessment. Baltimore's strong SREC market and supportive state policies continue to drive residential solar adoption.
Orientation Performance
Panel orientation significantly affects energy production. The table below shows relative output compared to true south-facing panels:
| Orientation | Relative Output |
|---|---|
| South | 100% |
| Southeast | 96% |
| Southwest | 96% |
| East | 85-90% |
| West | 85-90% |
| North | 60-75% |
