Solar Panel Recommendations for Dallas
- Fixed mount: Set your panels at 31.6° tilt, facing South (180° azimuth).
- Seasonal adjustment: Tilt to 17.8° in summer and 47.8° 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 Installation Considerations in Dallas
Dallas receives approximately 4.5 peak sun hours daily with over 230 sunny days per year. The North Texas climate features hot, humid summers and relatively mild winters, providing a long solar production season. However, spring and early summer bring frequent thunderstorm activity and hail risk that factor into installation planning.
Hail is one of the primary concerns for Dallas solar installations. While modern photovoltaic panels are tested to UL 61730 standards (1-inch hail at moderate velocity), larger hail during severe spring storms can cause damage. Choosing panels with reinforced glass and verifying that homeowner's insurance covers solar equipment are important steps. Some Dallas installers offer monitoring services that alert homeowners to production drops indicating potential damage.
Net metering through Oncor and other utilities in the Dallas area allows homeowners to earn credits for excess generation. With summer temperatures regularly exceeding 38°C, panels produce strongly during the same hours that air conditioning demand peaks. Dallas homes often have composite shingle roofs suitable for standard mounting hardware, and the city's relatively flat terrain means minimal shading from topography — though nearby trees should be evaluated.
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% |
| South-East | 96% |
| South-West | 96% |
| East | 85-90% |
| West | 85-90% |
| North | 60-75% |
Frequently Asked Questions
Are solar panels at risk from hail in Dallas?
