At the European level, the ambitious targets set by the Renewable Energy Directive require member states to incorporate renewable energy into their energy mix to the tune of 42.5% by 2030. This target is still far from being met in France.
It was against this backdrop that Triangle Horizon, which specializes in subcontracting large-scale solar projects, was founded in 2015 to meet the market’s growing needs.
Our Commitment to the Energy Transition
We stand out thanks to our comprehensive control over the production process, which is unique in France. From engineering to assembly, we manage every phase of a project from start to finish. From the design office to the fabrication of metal structures, through to the installation and commissioning of solar panels, our in-house expertise enables us to meet the highest standards.
At Triangle Horizon, our strength lies in our industrial capacity. With more than 490 MW of installed capacity, we are a leading player capable of meeting market demand on a large scale.
