The CPV module is a patented project named TwinFocus®. It uses an off-axis optical concentrator based on the combination of a quasi parabolic primary mirror and a secondary optic made of a quartz light guide.
The module is lightweight and compact, with a remarkably small thickness.
The technology adopted comes directly from the Automotive Lighting:
MATURE AND RELIABLE;
BASED ON RECYCLED / RECYCLABLE MATERIALS: POLYCARBONATE, ALUMINUM, GLASS AND STEEL.
It uses triple junction cells (3J) with large spectral sensitivity that stand high concentration and whose efficiency is not affected by operating temperature.
The thermal budget is handled with passive aluminum heat sinks, which are part of the mechanical structure.
CPV modules require high direct direct irradiation (DNI) and solar tracking. The system complies with IEC62108.
Two elements of concentrating mirrors. Dimensions are 405x290x160mm
TwinFocus modules are mounted on a dual-axis (astronomical and feedback, closed loop) biaxial tracker.
The solar trackers proposed are of two types:
A pole tracker that keeps the ground free for dual use (energy / agriculture, energy / parking, etc.) with a CSOC power up to 15 kWp.
Where a low profile is required turntable tracker is available, with CSOC power up to 7 kWp. (Attenzione al punto anche in Italiano)
