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)

Photowatt at Be Positive 2023 !

Large Format Project #1 : Enabling our 2 new huge capacity low carbon furnaces

Timelapse video ⌛ : Watch the installation in 2 minutes

The ” Large Format Project “ ? This is the ambition of becoming the first 100% European manufactured 210mm² wafers producer to anticipate the needs of tomorrow’s photovoltaïc market.

Photowatt decided to acquire new skills to optimize the performances of its new industrial production, through 5 steps that will be shared in the next few weeks.

First step : Two new huge capacity low carbon furnaces were implemented to accelerate our productivity, with below characteristics : 

  • 1.3 ton load per production cycle
  • Increasing productivity of 60% compared to old equipments
  • Decreasing the electrical consumption per kg produced

The target is to enhance the silicon crystallization performances, and to consolidate the leadership position of Photowatt in low carbon footprint.

How did our teams managed to move 12 tons furnaces ? Watch our 2 minutes explanation ! 👇

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.

The PHOTOWATT photovoltaic panels are ready in Alsace

Lux project

Delivery completed for the new photovoltaic plant in Lux, Côte-d’Or

A photovoltaic power plant with a capacity of 8.5 MW will soon be built in Lux, Côte-d’Or, on an 8-hectare plot of land that has not been used since 2016.

The project is supported by our client EDF Renewables and will have an estimated annual production of 9 GWh, equivalent to the average annual electricity consumption of approximately 2,140 households.

More than 20,400 Photowatt PW72LHT-C photovoltaic panels with an average power of 417 Wp were delivered to complete the plant.

2nd Sci & Tech meeting – PV IMPACT H2020 project

The 2nd scientific and technical meeting of the PVIMPACT H2020 project

Within the framework of the 2nd Scientific & Technical meeting (Sci & Tech) of the PVIMPACT H2020 project, our Photowatt’s R&D team hosted this past February 3-4, an online workshop focused on the compatibility of cast-mono silicon with current solar cells architectures and on the long term degradation of cast-mono cells and photovoltaic panels.

With the presence of renowned international experts, we discussed the state-of-the-art research and expertise regarding the behavior of this low carbon footprint material.

Special thanks to all participants for this rich exchange.

Roselend Project

The Roselend project aims to find new low-carbon solutions to ensure a harmonious balance between the economic development of the Beaufortain territory, pastoralism, green energy and biodiversity.

Renewable energies applied to agriculture

In Savoie, in the Beaufortain region, various organizations, including the Société d’économie Alpestre, EDF and Photowatt, are participating in the Roselend project, which aims to test the possibility of replacing diesel-powered generators with one powered by hydrogen and photovoltaics on mobile milking machines.

Replace diesel by a hybrid unit: Hydrogen / Photovoltaic

The diesel generators that power the mobile milking machines generate a lot of noise, smoke and odors for milking sites, wildlife, hikers, etc.
The use of a hybrid hydrogen/photovoltaic generator greatly reduces these nuisances because it is an almost silent device, without fumes or odors.

How does it work?

The demonstrator is composed of a hydrogen fuel cell, a battery, 3 inverters to deliver three-phase current, a control automaton and 6 Photowatt solar panels.
The unit is compact in order to be easily transportable (on a tractor or in a trailer), practical to use, robust and reliable.

The Photowatt photovoltaic panels

Photowatt supplied 72-cell bi-glass photovoltaic panels (PW72HT-C-XF) whose reliability will be evaluated at the end of the year in order to validate the resistance and the behaviour during the movement of the machine throughout the season.
