The invention relates to a signaling system, comprising a crossable zone intended to be positioned on a highway and comprising a signaling marking forming a plurality of signaling strips, said system being characterized in that:

Signalling system

A photovoltaic structure, or a photovoltaic structure for a roadway suitable for circulation of pedestrians and vehicles, including: at least one photovoltaic cell; and a non-opaque coating covering at least a front face of the photovoltaic cell and having an outer surface which is macrotextured and microtextured irregularly, with a mean texture depth MTD, measured according to the norm NF EN 13036-1, of between 0.2 mm and 3 mm, and a polishing resistance value PRV, according to the norm NF EN 13043, of at least PRV, or PRV, or PRV.

Photovoltaic structure for a roadway

A functionalized infrastructure including a bottom layer including a zone to be covered, the infrastructure including: n covering slabs arranged juxtaposed in order to pave the surface to be covered, each covering slab having a rank i, with i ranging from 1 to n and n being greater than or equal to 2 and including a coverage surface positioned to cover a part of the zone and at least one electrical functionalization assembly, the n covering slabs including at least one covering slab of a first type having a coverage surface of a first form and a covering slab of a second type having a coverage surface of a second form, each covering slab including an electrical connection block arranged on the slab so as to separate each slab of rank i from a slab of rank i+1 by a pitch (P) that is constant.

Functionalized infrastructure and method for installing such a functionalized infrastructure

The invention relates to a one-piece light signalling slab () comprising a structure with a plurality of layers that are superposed and attached together, said structure comprising:

Light signalling slab and system capable of using such a slab

Method of diagnosis for a photovoltaic generator characterized in that it implements a step of observing the evolution of its voltage when it passes from a short-circuit mode of operation to an open-circuit mode or vice versa.
