What to plan for in Longmont
- Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Hail (relatively high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- Wildfires (relatively high): Wildfire risk can mean planned shutoffs and smoke. A battery charged by solar gives quiet backup, and fueled generators need extra care on dry days and clear space around them.
