Soitec Connects Solar-Power Demonstration Plant in Namibia

June 10, 2013

Working with NamPower, Soitec demonstrates value of its CPV technology and commitment to Namibia by supplying electricity to an isolated rural community

BERNIN, France, June 10, 2013 /PRNewswire/ –

Soitec (Euronext), a world leader in generating and manufacturing revolutionary
semiconductor materials for the electronics and energy industries, has installed a
concentrator photovoltaic (CPV) demonstration plant in the isolated rural village of Usib
near Rehoboth in central Namibia. The new 25- kilowatt installation has been connected to
the grid of the national power utility, NamPower, and provides electricity for users
including a rural school. Soitec and NamPower have entered into a cooperative agreement in
which Soitec has constructed and operates the CPV plant and will transfer the knowledge
gained as well as operations and maintenance duties to NamPower.

“Building a project such as this one allows us to demonstrate the real-world
application of our CPV technology in hot and arid locations,” said Gaetan Borgers,
executive vice president of Soitec Solar Division. “Through our direct involvement, we
also can express Soitec’s commitment to improving educational opportunities and community
life. Our environmentally friendly and cost-effective alternative-energy solution provides
not only a reliable source of electricity, but also local jobs. We are actively deploying
our CPV systems in high solar irradiation regions around the world, and Namibia is a
perfect example of that strategy.”

Usib is an isolated rural community with a school providing education and
accommodations to more than 100 children from the surrounding area. Production from a
small vegetable garden supplements the diet of the school’s boarders. Additionally
Soitec’s subcontractor Alensy has installed a solar water pump at the community garden to
ensure there is sufficient water to irrigate up to one acre of crops. Funds from the sale
of electricity generated by the power plant and injected into the grid will be credited to
the school’s electricity bill. The power plant will be in operation for at least 20 years.

CPV is the most efficient technology in the photovoltaic industry, achieving current
energy-generating efficiencies of 30 percent – approximately twice that of conventional
photovoltaic technologies. Soitec’s CPV modules use a durable glass-glass design and
Fresnel lenses to concentrate sunlight 500 times onto small, highly efficient
multi-junction solar cells. By using dual-axis tracking, Soitec’s systems provide high,
constant power output throughout daylight hours. In addition, the company’s systems are
resistant to energy losses in high temperatures and achieve passive cooling without water
consumption, offering competitive advantages in countries with high direct normal
irradiance (DNI) such as Namibia. Soitec has installed its CPV technology in 18 countries
to date.
