1. A mounting device (MD) for a photovoltaic (PV) module, the mounting device (MD) being a molded device adapted to support and/or fix a photovoltaic (PV) module and comprising a polypropylene polymer composition, wherein the polypropylene polymer composition is a polypropylene copolymer composition which comprises 93 to 98 wt % of two or more polypropylene copolymers differing in their melt flow rate MFR2 (230° C., 2.16 kg) measured according to ISO 1133 or ASTM D1238 by at least 30 g/10 min and having the following properties:
a) a density measured according to ISO 1183, measured on compression moulded plaques of <920 kg/m2,
b) a melt flow rate MFR2 (230° C., 2.16 kg) measured according to ISO 1133 or ASTM D1238 in the range from 1.0 to 110.0 g/10 min,
c) a flexural modulus measured according to ISO 178 or −1% Secant according to ASTM D790 in the range from 700 to 2500 MPa,
d) a heat deflection temperature (HDT) measured according to ISO 75-1/75-2 at a load of 1.82 MPa in the range of 56 to 150° C., and
e) an Izod notched impact strength measured according to ISO 180/1eA at −20° C. in the range of 1 to 70 kJ/m2 or an Izod notched impact strength measured according to ASTM D256 at −20° C. in the range of 1 to 70 J/m
wherein the two or more polypropylene copolymer(s) comprising a heterophasic polymer having a melt flow rate MFR2 (230° C., 2.16 kg) measured according to ISO 1133 or ASTM D1238 in the range from 50.0 to 110.0 g/10 min.
