A method of installing a roofing system comprising fixing a plurality of elongated channels to a supporting structure such that the channels extend parallel to one another, whereby the channels may run from the top to the bottom of the roof; providing a plurality of photovoltaic modules 1, whereby elongated elements 3,4 are attached to opposite edges of the modules 1, the elongated elements 3,4 including downwardly extending flanges, preferably the elements 3,4 may be "T" shaped in cross-section; and placing the photovoltaic modules 1 in position on top of the channels so that the downwardly extending flanges of the modules fit in the channels. The channels may be formed with further "U" shaped channels to carry away any water. Protrusions 2 may also be added to the photovoltaic modules 1 such that the protrusion 2 will overlap with the module below. |
