DOME SOLAR (the leading company in the manufacture of photovoltaic panel mounting systems) has just integrated its affiliated company KOGYS (specialist in the manufacture of systems for mounting photovoltaic panels on the purlin on steel deck and sandwich panel roofs)..

AAfter acquiring a stake in the BACACIER Group last July, DOME SOLAR has announced that it has signed an agreement to take over its affiliated company KOGYS, on 20 December 2018.
KOGYS, created in 2006 and located in Montauban, is specialised in the design, manufacture and marketing of photovoltaic panel mounting systems. The company is a major player in mounting system design. After technical approval, their systems are mounted on the purlin, i.e. directly in the structure of the building, on steel deck roofs with the Kogysun + version and on sandwich panel roofs with the Kogysun i+ version, in order to guarantee excellent mechanical resistance.
As proof, in 12 years KOGYS has obtained 7 ATEX (Experimental Technical Approvals) and 5 ATEC (Technical Approvals) from the CSTB (Scientific and Technical Centre for Building).
With this transaction, DOME SOLAR consolidates its leading position in the manufacture of photovoltaic module mounting systems.

We are paving the way to be an indispensable partner in the construction of photovoltaic power plants for medium and large roofs. Today, for each type of roof, we can offer our customers solutions that have the most demanding certifications on the market in order to provide all the necessary guarantees to make their projects a reality.

Jean-Philippe Leray

Chairman of SAS DOME SOLAR

With this acquisition, I am very pleased to see DOME SOLAR undeniably strengthen its position as the number one player in the market for photovoltaic module mounting systems. It is now the company with the widest range on the market and can therefore meet the requirements of all types of customers and all types of projects. 

After more than 12 years spent in the business of manufacturing photovoltaic module integration systems, I can only thank all those who have put their trust in me since the beginning of this wonderful venture and tell them how satisfied I am that they can find within DOME SOLAR the same professionalism as that which drove me and will always drive me in this field of solar energy where so much remains to be achieved.
