Definitions

• the present invention relates to the field of photovoltaic roofs intended to be integrated into a building for professional or residential use or shelters of the shade type, comprising a longitudinal and transverse juxtaposition of modules provided with a plurality of photovoltaic cells, a structure carrier of said modules and intended to be fixed to the failures of a roof structure, cables and sets of connections.

• the invention lies in this third category.
• Photovoltaic modules can be integrated into existing roofs or new constructions. In both cases they are fixed to the breakdowns of the frame.
• photovoltaic modules can be mounted on the structures on the floor. If this reduces the duration of work on the roof, this has very little impact on the overall duration of the work.
