Hurricane Considerations
Corpus Christi sits in hurricane-prone territory. Solar installations must be designed to withstand high winds, and homeowners should understand how their systems perform during storm season.
Hurricane-Ready Solar
- Wind rating: Look for 150+ mph wind-rated mounting
- Ballasted vs attached: Attached systems generally safer
- Panel placement: Center-of-roof may be more protected
- Insurance: Ensure homeowner's policy covers solar
Storm Season Considerations
| Consideration | Recommendation |
|---|---|
| Mounting system | Hurricane-rated, flush mount preferred |
| Battery backup | Valuable for power outages after storms |
