However if you re still concerned about hail damaging your solar panels you can always make your own hardcovers.

Solar panel hail standard.

That includes many hail storms over the years we have had solar panels installed in alberta since 2001. The national renewable energy laboratory nrel researchers also work diligently to develop quality tests to ensure that solar panels will survive harsh weather like in a hailstorm 3 and not just in the wet or rainy seasons. Most solar panels have a high wind rating and have undergone testing to ensure that the solar panels can handle hail up to one inch in diameter. This means you don t need to buy expensive covers for your solar panel setup.

The answer is yes. The hail impact test is an important solar panel quality and safety test as in many parts of the world hail can cause major damage to solar panels.

One of these is iec 61215 which involves accelerated stress tests to see how well the module holds up under heat cold wind humidity uv light and mechnical stress including hail.

Thorough impact testing for pv panels to test resilience to hail damage. In fact manufacturers actually test their solar panels to ensure that hail storms won t be an issue. Generally solar panels can endure hailstones up to one inch in size 25mm at a falling speed of 50 miles per hour. About the hail impact test.
