Soitec’s New CPV Solar Module Features 31.8% Efficiency

Soitec announced its newest concentrated photovoltaic (CPV) module featuring
a power-generating efficiency of 31.8 percent. Soitec claims that its new
module, which is already in industrial volume production, has the highest
efficiency of any commercial product available for multi-megawatt
installations. The modules are part of the company’s tracker-based CPV
systems for high-capacity solar-power plants. Soitec’s CX-M500 module uses an
optimized anti-reflective coating and it employs Soitec’s Concentrix™
technology, comprised of a Fresnel lens plate and a bottom plate upon which the
solar cells are mounted. Fresnel lenses focus sunlight concentrated by a factor
of 500 on the solar cells which are precisely mounted on the bottom plate.

Soitec says that the CX-M500 module increases nominal peak power output over
previous generations from 2,335 Wp to 2,450 Wp. The new module has been
certified according to the International Electrotechnical Commission ‘ s (IEC)
and Underwriters Laboratories ‘ (UL) standards (IEC 62108, IEC 62688, UL 62108
and UL SU 8703) for safety, performance and reliability in the US and European
markets. Additionally it qualifies for performance-based incentives from the
California Energy Commission (CEC) and bears the CE mark for compliance with
relevant European Union standards.

Gaetan Borgers, executive vice president of Soitec’s Solar Energy Division
commented, “With our newest commercial modules and their higher
efficiencies, we are delivering on our cost-competitiveness roadmap.”
