How it works

Three steps to your estimate

Step 1

Confirm your hailstone size

Check local weather reports or news coverage for the reported hail size in your area, since this single factor drives most of the cost difference between a minor inspection and a major repair. The wind damage repair cost estimator covers the related risk if the same storm brought high winds.

Step 2

Include a wiring check for significant hail

Hail impacts can jar connectors loose even without visible panel damage, so pairing a panel inspection with the connector and wiring inspection cost estimator is worth doing after any storm above minor severity.

Step 3

Compare against your insurance deductible

If your estimated repair cost exceeds your deductible, filing a claim is usually worth it. If it's close to or under the deductible, paying out of pocket may be simpler than going through a claim process, and the panel replacement cost calculator can double check pricing if full replacement is needed.

Understanding hail damage to solar panels

How much hail solar panels can actually take

Most residential solar panels undergo standardized hail testing and are certified to withstand impacts from roughly 1 inch diameter hail traveling at terminal velocity without damage, a threshold set by independent testing standards used across the industry. Below that size, panels typically show no lasting effect even after direct hits, which is why small hail events usually only warrant a precautionary check rather than an assumption of damage, similar to the low-risk end of the micro crack risk over time estimator.

For practical guidance on pre-storm preparation for hail and other severe weather, the Department of Energy's guide to storm hardening and post-damage recovery is worth reading.

Where damage risk climbs sharply

Once hailstones exceed roughly 1.5 inches, the risk of actual glass cracking rises substantially, and hail above 2 inches, sometimes called severe hail, can shatter cells outright or cause damage across a large portion of an array in a single event. Wind-driven hail, where stones hit at an angle rather than straight down, can also cause more damage than the raw hailstone size alone would suggest. For the actual impact-resistance testing panels go through, UL's photovoltaic module safety standard lays out the technical specifics.

The hidden damage problem

Not every hail impact leaves a visible crack. A moderate hit can create a micro crack inside a cell without breaking the surface glass, a form of damage that often goes unnoticed until it eventually reduces output months or years later. The micro crack risk over time estimator covers how this hidden risk accumulates and when a deeper inspection is worth the cost. Since hail exposure also depends heavily on roof type and mounting, the roof condition checklist cost impact tool covers that connection in more depth.

Working through the insurance process

Most homeowners insurance policies treat solar panels as a covered structure similar to the roof itself, though the exact terms and any solar-specific riders vary by policy and provider. Getting a documented repair estimate before filing, along with photos of the visible damage if any exists, makes the claims process smoother regardless of whether you ultimately decide to file, and pairing that estimate with the warranty coverage value calculator clarifies what your manufacturer warranty might already cover. If a repair might be rolled into financing, the total cost including financing fees calculator can help you see the full cost picture

Questions

Frequently asked

Yes, though most residential panels are certified to withstand hail up to roughly 1 inch in diameter at terminal velocity without damage. Hailstones larger than that, especially above 1.5 to 2 inches, can crack panel glass, create hidden micro cracks, or in severe cases shatter cells outright.

In most cases yes, since solar panels are typically covered under a homeowners policy as an attached structure or scheduled equipment, similar to a roof. Coverage details and deductibles vary by policy, so confirm your specific solar coverage with your insurance provider.

Visible cracks in the glass or a noticeable drop in output on your monitoring app after a hailstorm are the clearest signs. Since hail can also cause hidden micro cracks with no visible damage, a professional inspection after any significant hail event is worth scheduling even if nothing looks obviously wrong.

It can, though weather-related claims are often treated more leniently than other claim types since they're not related to homeowner negligence. Ask your insurance provider directly how a hail claim would affect your specific policy before deciding whether to file.
