Launet Construction wanted to reduce its carbon footprint by producing part of the energy consumed by its metal frame assembly process in a more environmentally-friendly way. To achieve this, it turned to our experts at Eiffage Énergie Systèmes, who provided end-to-end support in developing a viable project.
“Thanks to the engineering studies carried out prior to the work, we were able to determine the optimum technical and economic configuration for the system. Based on an annual production of 136 kWp, 75% of the energy produced will be consumed by the factory, representing 22% of total electricity consumption, or nearly a quarter of the energy mix. Under these circumstances, it didn’t make sense to install more panels, as the surplus energy couldn’t have been consumed by the factory. It would have had to be fed directly into the national grid, which is not necessarily cost-effective," explained Sales Director Quentin Mérel. In other words, a facility twice as large (and therefore twice as expensive) would have covered, at best, only 26 to 27% of the factory's total electricity consumption.
Launet Construction has the expertise to install its own photovoltaic shade structures, but chose to follow our experts' recommendations. The PV system has been mounted on the roof of a shed with ideal sun exposure and blends perfectly into its surroundings. It covers an area of 500 m². ”Once the project design had been finalized, we put together an administrative file to obtain the necessary permits prior to the work. Antoine Delassus, head of operations at the Wimille branch (62), and his team drew on their expertise to complete the project in just three weeks, during the factory's annual closure,” continued Quentin Mérel. Our experts, whose agency is a benchmark in PV facilities in the Hauts-de-France region, first installed a mounting structure on the shed roof. They then fitted 300 PV panels, which they connected to the delivery point. They also brought the plant’s transformer into compliance.
In a context where technical, regulatory and administrative requirements are constantly changing, the support provided by Eiffage Énergie Systèmes was key to the project's success. Our specialists drew on all their expertise, from design to implementation, without neglecting the administrative and financial aspects. “We assisted Launet Construction with the financial structuring of the project, so that repayment of the loan taken out to pay for the facility would only begin after one year of use. By then, the savings made on the electricity bill will more than cover the repayments, especially as the first few months of production are in line with expectations,” said Quentin Mérel.
Launet Construction particularly welcomed this comprehensive approach to designing a solution tailored to the company's needs, economically viable and integrated into its environment.
