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 Modules are operational in Alsace

4.6 MW of PHOTOWATT’s modules 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 modules 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 modules 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 modules 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 modules.

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 modules

Photowatt supplied 72-cell bi-glass modules (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.

PV Cycle France becomes Soren

In order to redefine its role in the support of the industrial and technical development of the sector, the eco-organization PV Cycle has adopted a new visual identity under the name of Soren

Since Wednesday, July 7, the Sorenbrand has replaced that of PV Cycle France and uses this evolution to present its ambition for the sector and the technological and technical challenges that all its players will have to face together: the alliance of the energy transition and the circular economy.

What is Soren?

Soren is a non-profit eco-organization approved by the public authorities for the collection and processing of used photovoltaic panels (private and professional) in France, bringing together more than 340 member companies that have chosen to collectively manage the issues related to end-of-life equipment. Between 2015 and 2020, more than 15,000 tons were collected at no cost to the holders directly from the dismantling sites or through the network of voluntary drop-off points. The recovery rate for a crystalline silicon-based photovoltaic module with an aluminum frame currently varies between 90% and 94%.

EDF ENR PWT is one of the founding shareholders.

Photovoltaic awnings on the parking lots of the Bugey nuclear power plant

16,000 Photowatt modules will complete the installation of solar awnings for an estimated annual production of 6.3 GWh

In collaboration with EDF Renewables, the Bugey nuclear power plant has embarked on a large-scale project to promote the energy mix by equipping its parking lots with photovoltaic awnings.

The worksite took place in two phases. The first phase began in September 2020 on one of the plant’s parking lots where 11,700 panels were installed with an estimated annual production of 3.9 GWh. On the second phase of the site, the annual production is estimated at 2.4 GWh.

In total, the annual production of solar electricity is estimated at 6.3 GWh, of which 16,000 Photowatt panels will complete the electricity production of the nuclear power plant without CO2 emissions.
