Announced as a first world, supported financially by OSEO and labeled by the pôle de compétitivité Up - Tex "this flagship project, which mobilizes today about 10 people in Dickson, was born in 2005 of an internal reflection on the future of a Web store functionality," says Vincent Baudelet, "market manager" of this company specializing in technical improvement of habitat textileslocated in Wasquehal (North). Two years later, with the cooperation of the national school superior des arts et industries textiles (Ensait), which supports this project from the beginning, the first prototype was created.
Became functional the last year, this prototype of PV store already exists in two versions: one, residential, development with Somfy contest and the other, adapted to the campsite, developed in partnership with Omnistor. Other current applications include, among other things, a marine model for the awning of a boat.
The final product will be consistent with these prototypes For the home version, "we're working even on the improvement of the Assembly of the cells on the canvas by rolling and connections, i.e. the delivery of electricity without loss", said Vincent Baudelet, pointing out that these two processes were the subject of patenting by Dickson. "We will make the acrylic canvas, assemble the cells and connections, before delivery in rolls of garment manufacturers or manufacturers of blinds."
Current bought by EDF
What fundamental difference with photovoltaic technology classic Rigid panels with crystalline silicon, this solar canvas uses ultrathin cells, of a thickness less than mm and weight pen (600 grams per square metre). These flexible cells, covering 60 to 98 of the surface of the canvas, are flexible enough to be coiled at the same time as the latter. The range of work thus deployed, higher than the traditional rigid panels, partly offsets the lowest instantaneous power of flexible amorphous silicon cells.
How this semiconductor material converts solar radiation into electricity When the photons of light encountered the surface of a photovoltaic cell, Silicon Electron are "torn" by the clash, creating a movement that will generate a continuous electrical current. The electricity thus produced by the store will be then directed to a UPS that will transform the current alternative before re-injecting it in the network of EDF (for the France), who buys very cheaply (0.55 euro per kilowatt hour).
To optimize the production of energy, even in the absence of the occupants of the House, and extend the lifetime of the cell, a motor controlled by a weather station (sun-wind) operates the store automatically during thinning and wound it in windy events. But grey and rainy weather is not an obstacle to its proper functioning, because "the amorphous silicon is very sensitive to light and works even when the time is weakly sunny, unlike the crystalline silicon", said Vincent Baudelet. For the time being, the estimation of the production of this type of store is based on a Sunshine of 1,000 watts per square metre for a maximum yield of 40 cells W/m2 (or 4).
Return on investment
As with all technologies pioneers, the potential of this new product is difficult to estimate at this time. "In a market estimated at approximately 150,000 stores awnings per year, annual French there seems not utopian to 5 of this volume", said Vincent Baudelet. As the public selling price, first estimates the set to double that of a conventional store. Given the 50 tax credit granted to photovoltaic installations and the opportunity to resell the electricity, return on investment is around seven years.
