Soitec Reports Excellent Performance of Concentrix CPV System Connected to Jordan’s Grid

     - Average solar-to-grid efficiency reached 21%, with daily peak       efficiencies regularly reaching 25% and beyond (2 to 3 times higher       than standard photovoltaic installations, even in ambient temperatures       of up to 45degreesC).      - The system has been running on a continuous basis, with 100% uptime,       demonstrating its reliability in a harsh environment.      - The measurement data confirm that the annual specific electricity yield       will be as high as 2500 kWh/kW of installed nominal AC power. This       extraordinary high value is a result of the site's high level of direct       solar irradiation in combination with the great performance of the       system.

Especially at locations with extremely hot ambient temperatures, CPV systems perform better than conventional solar systems and therefore guarantee a high and constant power production throughout the day. Due to the very-low-temperature coefficient of their III-V multifunction concentrator solar cells, the performance of CPV systems is much less affected by temperature than any other PV technology, particularly those that are silicon-based. In fact, in extreme heat, silicon-based PV systems suffer from a three times greater loss in efficiency when compared to systems such as Concentrix CPV technology, which is based on III-V semiconductor materials. For this reason the technology shows best performance even during summer when electricity demand is particularly high due to air conditioning requirement – and all this, without any requirement of cooling water. This makes CPV technology perfectly suited for power plant installations in arid areas like in the MENA region.

Due to the technology’s high scalability, CPV power plants can be commissioned in phases, thereby shortening the time to operation. In fact, the first units installed and connected to the grid can immediately start to produce energy, even while the installation of subsequent systems is in progress. Once operational, CPV’s peak production hours align with the region’s peak electricity demands from air conditioning.

About Soitec

Soitec is the world’s leading innovator and provider of the engineered substrate solutions that serve as the foundation for today’s most advanced microelectronic products. The group leverages its proprietary Smart Cut(TM) technology to engineer new substrate solutions, such as silicon-on-insulator (SOI) semiconductor wafers, which became the first high-volume application for this proprietary technology. Since then, SOI has emerged as the material platform of the future, enabling the production of higher performing, faster chips that consume less power.
