Concentrix. Focus on Power.
Principle of Concentrating PhotoVoltaics (CPV)
3
From solar cell to solar power
plant:
• CPV focuses sun light onto
solar cells made from high end
semiconductor materials
• Solar cells are built into
modules
• CPV power plants are built by
a multitude of modules on
tracker systems
28% module efficiency
(30% expected this year)
25% power plant
efficiency is the
highest in the world
(27% expected this
year)

System data
• Location: Ma’an Development
Area
• Installation: May 2010
• Installed power:
5,88 kW AC nom
• Nominal conditions are:
DNI: 850 W
ambient temperature: 25°C
• ACTUAL Performance:
5,921 kW
on a hot summer day (1 Sept)
Screen shot of the Concentrix Control System:
High power output at high DNI

Typical CPV power output over a sunny day
8
System data from
Ma’an, Jordan:
• No significant
change of power
output from July to
October;
• shorter production
time in October is
due to less sun
shine hours per day

Peak Performance
• at highest irradiation
• at high temperatures
• System Performance:
the 5880 W system
generates 6416 W
on a hot summer day
(31 Aug 2010)

At 850 W/m² irradiance, the
performance is practically
constant even at higher
ambient temperatures

Influences on system efficiency
and system performance
• System efficiency is
independent from irradiation
• Cleaning influences yield
Regular cleaning every 7 days
Sandstorm and poor cleaning
but still higher efficiency than
Si-PV
