Sireos, a major player in the energy transition

Welcome to the dynamic world of renewable energy and energy transition ! At Sireos, we are proud to be part of this significant transformation as a company specializing in the design and construction of large-scale photovoltaic solar power plants. In an era where energy transition is becoming a global priority, we firmly believe that the future will be shaped by renewable energies, particularly solar energy. It is in this spirit that our company is actively committed to playing a key role in the construction of photovoltaic solar power plants. We recognize that solar energy represents an inexhaustible and environmentally friendly energy source. However, to fully harness its potential, it is essential to have advanced, efficient, and reliable technologies. This is precisely where our teams play a crucial role in supporting stakeholders in this sector, both today and tomorrow.

Every day, our team of enthusiasts works tirelessly to deploy power plants that not only maximize quality but also enhance performance and reduce construction costs. With our commitment to the quality of our services and our ability to anticipate market needs, we are able to offer a wide range of customized projects. Each of these projects is carefully tailored to the unique specifications of our clients. ustainability in construction and relationships with all stakeholders is the central pillar of our corporate philosophy. At Sireos, we take pride in playing our part in building a cleaner and greener energy future. Every initiative we undertake is guided by our shared vision of contributing to a world where solar energy becomes the norm.

  • Ground-Mounted Solar Farms

    Much more than a simple installation, our ground-mounted photovoltaic power plants embody the power of the energy transition. Built on dedicated plots of land, these power plants use vast areas to capture the sun’s energy as efficiently as possible. At SIREOS, we deploy advanced expertise in the design, construction and maintenance of these power plants, thus maximizing their efficiency and optimizing construction costs.

  • Floating Solar Power Plants

    At the forefront of innovation, floating photovoltaic power plants provide technological access to previously inaccessible land. At SIREOS, we rely on a dedicated, expert engineering department to create floating solutions that meet the unique challenges of this approach.

  • Solar carports & Canopy Power Plants

    Our photovoltaic power plants on shade structures transform parking spaces into generators of electricity from renewable sources. At SIREOS, we offer, in partnership with our partners, shade structures incorporating solar panels while providing functional shelter. This approach combines utility, aesthetics and energy efficiency.

  • Agri-Photovoltaics

    Combining agriculture and solar energy, our agrivoltaic power plants allow our customers to exploit agricultural land in an innovative way. At SIREOS, our agrivoltaic approach aims to optimize land use, promoting harmonious cohabitation between agriculture (livestock or crop production) and the production of renewable energy.

  • Roof-Top Solar Power Plants

    Whether on industrial or commercial buildings, we transform unused surfaces into sources of clean energy. At SIREOS, our expertise in roof installation ensures harmonious integration, taking into account all normative technical constraints or those due to use, thus contributing to the energy transition, allowing compliance with the law for owners.

  • Energy Storage System

    Whether to smooth production from intermittent sources or to guarantee uninterrupted power supply, the storage systems offered play a central role in creating a resilient energy network.
