Sonnenkraft 420 Wp HC Glass PV Module bifacial 15% Transparency (1766 mm x 1165 mm x 9 mm)

Hail protection classes
The risk of hail has increased considerably in recent years. This trend is also illustrated by various damage statistics. In general, more than one third of building damage caused by natural events is attributable to hail. As a result, the majority of our photovoltaic modules also offer added value in this respect and are therefore equipped with hail resistance class 4 from a front glass thickness of 3mm. Hail of this size is „golf ball-sized“ and has a diameter of 40mm as well as an impact velocity of 99km/h.

DIBt approval for SONNENGLÄSER
A general building authority approval from the German Institute for Building Technology (DIBt) is available for our SONNENGLÄSER. Thanks to the approval, these are regarded as regulated building products (analogous to classic VSG glass) and no longer require individual approval for each project.
