Ecosun Plus

LED-based Sun Simulator, Certified A+A+A++ by TÜV InterCert

The Ecosun Plus is the unbeatable solution with a highly accurate performance for high volume production testing of PV modules, enabling unsurpassed efficiency measurements of solar cells, reducing operating costs over the systems lifetime.

Ecoprogetti’s sun simulator performs I-V curve measurements for all the new generations of solar modules and thanks to a Steady State Irradiance test it works also for all the new high-efficiency solar cells. With the most advanced 18-colour LED-based technology (lifetime equivalent to 10GW of produced modules), the Ecosun Plus can be used for testing both standard crystalline solar modules and CIGS solar modules, with the possibility to perform Light Soaking for Thin-film solar modules as well.
The measurements for testing the efficiency of PV modules and the I-V curve can be performed without wasting time between one test and the other, thanks to the absence of recharging times.
The certified A+A+A++ levels of Spectrum(A+), Non-Uniformity(A+) and Instability(A++) are the most advanced in the market.

To guarantee a long life of the photovoltaic module and the safety of the installation, Ecoprogetti offers an instrument which checks the electrical insulation of the modules during the production process in respect of the norm IEC 61215/61730.
The instrument permits to perform the Hi-Pot test with a maximum voltage of 6kV DC.

The technicians and staff of Ecoprogetti srl is at your disposal for any clarification or specific questions about our PV production equipment and for the realization of your specific solution.
