Exosun and Soitec combine their expertise to bring to market a new concentrator photovoltaic system
Exosun, French expert in the design, development and supply of solar trackers for ground-mounted utility-scale solar power plants, and Soitec, world leader in the supply of concentrator photovoltaic (CPV) modules, have joined forces to offer a new CPV system.

Comprising an Exosun tracker holding 18 to 24 Soitec CPV modules, this CX S540 model delivers output per unit reaching up to 61.2 kW. Already being sold by both companies, it will be used in the majority of CPV projects that the French Ministry of Energy selected at the end of the second call to tender for large-scale photovoltaic installations that the French energy regulator, the CRE, issued in March 2013.

Exosun designed and developed dual axis solar trackers using a patented control system to give excellent tracking precision of 0.1°. Going by the name Exotrack® CPV, they combine technical and economic performance to exploit the full potential of Soitec's CPV modules. The drive mechanism, parts tolerance and assembly procedures have been designed to be practical, flexible and modular under any large-scale installation. These trackers blend perfectly into the landscape, and are simple, fast and easy to install and maintain.

The leader in concentrating photovoltaic technology, Soitec meanwhile developed modules achieving up to 31.8% efficiency. Using Fresnel lenses, light is concentrated 500 times before it reaches the triple-junction cells which convert the sun's rays into electricity. The use of highly resistant materials such as glass and metal ensures the robustness and the durability of every module.

Combining the performance of the Exosun trackers and the Soitec modules, CX S540 systems maximize power generation while optimizing the footprint and keeping the height down to 4.5 meters (under 15 feet).
