What to plan for in Cary
- Hail (relatively high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- Heat waves (relatively high): Heat waves strain the grid just when air conditioning matters most. Decide what must stay cool, such as one room, medicine and the fridge, and size backup to that rather than the whole house.
