About REDEN
Company Overview
Name
REDEN, an independent entity of the REDEN SOLAR group, a private simplified joint-stock company (SAS) with Macquarie Asset Management as the majority investor (source: linkedin.com)
HeadquartersRoquefort, France
Year Established2008
SizeApproximately 30 employees within REDEN SOLAR, with over 270 professionals across the REDEN SOLAR group located in France and internationally (source: data.gouv.fr, linkedin.com, vie-economique.com). REDEN SOLAR reported revenue of €17.8 million in 2024 (source: verif.com).
What They Do
REDEN is an independent electricity producer specializing in the development, financing, construction, operation, and ownership of photovoltaic assets and battery storage systems. Their industrial model includes a photovoltaic module assembly unit located in Roquefort, combined with an operational division managing the construction, operation, and maintenance of solar power plants (source: reden.solar, reden.solar). REDEN offers a comprehensive range of solutions including ground-mounted solar farms on degraded land, agrivoltaic projects tailored for livestock and large-scale agriculture, agrivoltaic greenhouses and pergolas, as well as hybrid or standalone energy storage systems (source: linkedin.com). The company emphasizes responsible photovoltaic energy production by controlling the supply chain through its industrial unit, setting it apart from developers who outsource module supply (source: reden.solar).
Projects and Achievements
Among its notable achievements, REDEN launched a 200 MW solar module production line in Roquefort at the end of 2024, capable of producing up to 300,000 panels annually, with low-carbon certified modules ranging from 405 W to 545 W (source: solarstoragextra.com). This plant, commissioned in December 2024, was however shut down in mid-2026 due to cost pressures and Asian competition (source: pv-magazine.com). REDEN operates an installed solar capacity of approximately 1.1 GW, mainly across France, Spain, Portugal, Italy, and Germany, with an extended presence in Chile, Mexico, and Puerto Rico (source: reden.solar, linkedin.com). The group is also distinguished by its expertise in agrivoltaics, developing systems compatible with livestock and agriculture, as well as innovative infrastructures such as agrivoltaic greenhouses and pergolas (source: reden.solar).
Recent Developments
The past two years have been marked by the launch and subsequent shutdown of the photovoltaic module production line in Roquefort, highlighting the industrial challenges posed by international competition (source: solarstoragextra.com, pv-magazine.com). Meanwhile, REDEN has continued its geographic expansion and project portfolio development across Europe and the Americas, strengthening its position as a pioneer in agrivoltaics (source: linkedin.com, vie-economique.com). The company continues to invest in its industrial and operational capabilities while consolidating its presence in several countries, including France, Spain, Portugal, Italy, Germany, Chile, Mexico, and Puerto Rico (source: reden.solar).

Its integrated model, combining development, financing, construction, and operation, offers opportunities at its French offices in Roquefort, Toulouse, Bordeaux, and Nîmes, as well as within its international teams (source: reden.solar, linkedin.com).
