Conergy France collaborated with Soligest to complete three rooftop solar establishments, with a total power rating of 6.1MW. More than 80,000 thin-film modules have been installed on 67,000m2 of roof surface. Conergy was responsible for both the design and technical planning of the installation.
The largest of the three systems, at 2.7MW, was connected to the public grid at the end of January. It was installed on top of a logistics centre in Thiers, Puy-de-Dôme in France; a 2.3MW installation is located in Bollène in Vaucluse; and a smaller 1.1MW installation will now produce energy on top of a warehouse in Maine-et-Loire.
Together, these three industrial rooftop installations will produce 6.5GWh of clean electricity from the sun per year, the equivalent of the energy consumption of around 2,200 households. This represents a saving of 3,130 tons of damaging CO2 emissions - the equivalent of 45 trucks driving the 738km between Montreuil (49) and Bollène (84).
"This project has been a great success for Conergy France", says the head of Conergy France, Xavier Ansaldi. "It is our biggest project so far this year and once again our expertise and many years of international experience in major free-field projects and rooftop installations has stood us in good stead."
Soligest installed the systems but will also operate them. Arnaud Maillard, sales manager at Soligest added: "We are delighted with the way everything went so smoothly with our partnership with Conergy, especially when you consider the size and complexity of the project. With the benefit of this experience we know that we now have a very strong team for carrying out future rooftop installation projects, both large and small. We can certainly envisage working with Conergy again".
The three large-scale installations involved in the joint project all benefit from what is known as "tariff protection", so the feed-in tariffs applied will be those that were valid at the time the project was planned back in 2010. Although legislation has changed in France recently, private, medium and large-sized rooftop installations can still be lucrative. Experts estimate that in the coming year the combined output of medium-sized rooftop installations up to 100kW and larger installations up to 250kW will be around 220MW.
