Fil’RSun project kick-off

Developed by Photowatt R&D, EDF Hydro, EDF R&D and the company Mécamont, this innovation project aims to provide new solutions for photovoltaic development in a context of growing scarcity of land dedicated to large-scale projects.

The Fil’RSun project was officially kicked off on Thursday February 8 in the presence of all the stakeholders. This collaborative project, supported by European LIFE funding over a 3-year period, will be developed by our R&D Department in partnership with teams from EDF Hydro, EDF R&D and Mécamont.

The purpose of the program is to develop new photovoltaic solutions in response to the current problem of access to land in France. The program involves the deployment of photovoltaic modules suspended over hydroelectric canals, whose potential is estimated by EDF at 2GWp in France.

Groupe de travail pour le projet Filsun à Carbonne

Land use conflicts are an increasingly important constraint on the large-scale development of photovoltaic solar energy. As a result, innovations such as the so-called “Agrivoltaic” installations are appearing, whose common feature is the dual use of land.

The Fil’RSun project is fully in line with this logic of installing photovoltaic systems on an already artificial surface, thus increasing the value of the land.

Prototype Filsun

The project consists of developing and installing a 1MWp demonstrator with low-carbon bifacial photovoltaic modules supplied by Photowatt and supported by cables over a canal connected to an EDF hydroelectric power station located in Haute Garonne.

EDF HSO is the project leader and will be the final operator of the photovoltaic plant. Mecamont is responsible for the structural design and installation of this industrial pilot plant.

Our solar panels at the 2024 Games

More than 4,000 Photowatt solar panels supplied for the new Village and the Saint-Denis Aquatic Center


Photowatt is proud to announce its major contribution to the sporting event of the year by supplying 1.5 MWp, including over 1,600 state-of-the-art solar panels for the new sports village and around 2,500 panels for the Saint-Denis Aquatic Center, both projects led by EDF ENR.

Beyond the high-level sport celebration, the event that will take place from July 2024, represents a unique opportunity to promote sustainable development and leave a positive impact on the environment. With this aim Photowatt has committed to provide high quality solar solutions with a low carbon footprint for these installations.

First images of the Ecrouves solar park

The first community solar park in the Grand Est region will feature 25,000 Photowatt panels

La SAS Parc Solaire de L’Espace du Génie, formed by SEM SipEnR, ENErgic, Énergie Partagée Investissement and the Communauté de Communes Terres Touloises,was created for the construction of a citizen’s ground-mounted photovoltaic park in Écrouves, Meurthe-et-Moselle.

Located on a former polluted site in the commune of Ecrouves, the project began construction in autumn 2023 and should be operational in summer 2024.

With an output of 12 MW and an annual production of 13.2 GWh, this photovoltaic plant will produce the equivalent of 77% of the total electricity consumption of the commune of Ecrouves and 5% of the Communauté de Comme Terres Touloises.

A new photovoltaic power plant in Flayat, Creuse

Photowatt supplies more than 12,000 low-carbon photovoltaic panels for a new 10 MW plant in Flayat, Creuse.

Installed on a surface of 10.8 ha, the new solar power plant at Flayat comprises 2 units of 5 MWp each: Flayat-A and Flayat-B. The plant, developed by the Générale du Solaire group, uses over 12,000 low-carbon photovoltaic panels supplied by Photowatt.

11,074 bifacial panels PW72LHT-CB-XF, new-generation modules that capture solar energy from both sides, front and rear, optimizing the yield of each module thanks to light reflected from the ground.

980 monofacial PW72LHT-C low-carbon panels

These two ranges of low-carbon photovoltaic panels are manufactured using French-developed, more sustainable production techniques and low-carbon footprint materials, reducing the environmental impact of the installation throughout its life cycle.

⚡10 MW total capacity

⚡More than 12,000 Photowatt panels on the Flayat B unit (5 MW)

⚡Around 2,000 households supplied with electricity per year on the Flayat B unit (excluding heating)

Retzwiller Project

Project Retzwiller : 11 000 photovoltaic panels are operational in Alsace

4.6 MW of PHOTOWATT’s photovoltaic panels are powering 2000 homes daily

The whole power production is dispatched in the public network and fill 18 to 20% of the territorial yearly consumption, which is 5700 MWh per year.

The Retzwiller project started back in 2018 with the building permit allowal on the field of the old Gilardoni’s Brothers factory that was left abandoned. The Project leader Tryba Energy trusted PHOTOWATT’s experts to ensure the whole production of 11 000 photovoltaic panels PW72LHT-C.

The revaluation of this orphan space allowed to avoid the creation and use of a new field. Moreover, this wide french-based project is important economicaly and localy speaking, because it involved companies of the sector to support the development and installation of the power plant.
