Worried about your solar panels in extreme weather? Here's exactly what happens to solar panels in hurricanes, hailstorms, wildfires, and heavy snow — and how to protect your investment.
One of the most common questions we get from homeowners considering solar: "What happens to my panels if a big storm hits?"
It's a smart question — especially if you're in Texas (hail), Oregon (wildfires), the Gulf Coast (hurricanes), or Michigan (heavy snow). Solar panels are a 25-year investment, and knowing how they hold up in extreme weather is essential before you commit.
Here's the real story — no sugarcoating.
Most modern solar panels are tested to withstand wind speeds of 140 mph (some up to 180 mph) when properly installed. The key phrase is 'properly installed' — the mounting system and the quality of the roof attachment matter as much as the panels themselves.
Panel failures in hurricanes are almost always a mounting failure, not a panel failure. If the racking wasn't installed with the right fastener depth, spacing, or sealant, the panels can lift. Flying debris is the second cause — a direct hit from a large object can crack panels even if they're rated for wind.
Tier 1 solar panels are tested to withstand 1-inch hail at 51 mph (UL 61730 and IEC 61215 standards). That covers the vast majority of hail events.
After major Texas hailstorms, most properly installed systems survived intact. Angled installations shed hail energy better than flat mounts.
Hail damage is covered by standard homeowners insurance in most states. Make sure your solar system is listed as a covered structure on your policy.
Larger, rarer hail events (golf ball size and above) can crack panels, but this is uncommon. Some insurers require a separate rider for solar — confirm this before you install.
Solar panels themselves are fire-resistant — they're rated Class C or higher for fire exposure. They won't catch fire from embers or radiant heat in most wildfire scenarios. However, if a structure fire starts on your home, panels can be damaged by direct flames.
Wildfire smoke significantly reduces solar production — sometimes by 30–50% during heavy smoke events. This is temporary. Once air quality clears, production returns to normal.
If you're in our Pacific Northwest service area, pairing solar with battery backup is especially valuable during wildfire season — both for production resilience and for grid outage protection when utilities shut down lines to prevent sparking new fires.
| Scenario | Impact on Panels | What To Do |
|---|---|---|
| Light snow (< 2 inches) | Minimal — melts quickly | Nothing, panels self-clear |
| Heavy accumulation | Temporary production loss | Let it melt; don't scrape |
| Ice damming | Potential mounting stress | Inspect mounting in spring |
| Prolonged overcast | Reduced output, not zero | System still produces |
Modern panels are load-tested to 5,400 Pa (about 113 lbs per square foot) — more than enough for even heavy snow accumulation. Panels are also slightly warm from electricity production, which accelerates snow melt. Michigan and New York homeowners: your systems will still produce meaningful power in winter, just less than in summer.
Quality equipment + quality installation = weather-resilient solar. The most important protection is choosing an installer who uses Tier 1 panels, pulls proper permits, and installs to local wind/snow load codes.
