Additional information about application

The TW Solar TWMND-72HD590W panel has been designed for high energy production and reliable operation in large photovoltaic installations. It will work well in commercial, industrial, roof and ground-mounted PV farm installations.

The bifacial glass-glass design allows for increased energy yield in places where the back side of the module can use light reflected from the ground, e.g. on light roofs, ground structures or surfaces with a high reflectivity.
