The structure of the roof will require no reinforcements nor alterations thanks to Heliatek’s innovative HeliaSol technology, with the secondary school being able to produce 23.8 MWh of electricity per year, the equivalent to five local households. The electricity will be directly used by the school to fulfil 15-20% of its power needs.
ENGIE has held a stake in Heliatek, the developer of the HeliaSol technology, since 2016, and has explained that the goal of this investment is to experiment with the technology to open up longer term large-scale development. The new technology is an organic PV film suitable for lightweight roofs, flat or curved, on which it would not ordinarily be possible to install traditional PV technology. Heliatek also claims that HeliaSol technology is faster to install and easily recyclable.
“Renewable energies are an essential part of our strategy, based on a decarbonized, decentralized and digitized world,“ said Isabelle Kocher, CEO of ENGIE. “And half of all energy consumption comes from the building sector. For them, solar energy is increasingly an opportunity and, thanks to OPV technologies, buildings which up to now were unable to benefit from the advantages of photovoltaic energy will now be able to use it. Our partnership with Heliatek allows us to play our full role as supplier of the best solution tailored to each customer.“
Engie has a stake of 6.6% in Heliatek, and its investment in the firm was part of a large-scale plan to change the company’s image, and for it to become more involved in renewable energy.
