Most panels handle typical hail without damage. Australian standards require every panel to survive 25mm hailstones at 83 km/h, and many modern panels perform well above that.

The risk climbs significantly above 35 to 40mm. Parts of southeast Queensland, inland NSW and Victoria regularly see stones larger than that. If you’re in one of those areas, panels certified to the Swiss VKF HW4 standard give you a meaningful step up in protection.
