Endeas is delivering fully automated QuickSun all-in-one testing stations to a new PV module factory for the final quality inspection of heterojunction (HJT) modules. The new systems, providing annual testing capacity of up to 750MW, will be delivered in the third quarter of 2019 to a leading non-Chinese PV manufacturer. All systems are equipped with a class A+A+A+ solar simulator; automatic EL and optical inspection; and hipot, ground continuity and bypass diode tests.
"We are delighted to see how quickly our CAC method has gained acceptance within the PV industry. Applying a scientifically sound correction for the capacitive effects enables the industry to measure HJT and other high-efficiency technologies with uncompromised accuracy and reliability. An additional advantage is that there is no need to compromise the lifetime of established Xenon tubes by applying unnecessarily long flash pulses. Neither is there need to apply LED technology, avoiding their fundamental deficiencies such as a non-continuous spectrum, instability problems with ultraviolet LEDs, and the risk of shipping a large number of modules measured with partially broken LED boards", says Endeas' Managing Director Mr Jaakko Hyvärinen. He adds, "As for comparison, the Xenon flash tubes in Endeas' simulators are individually monitored in real time, which ensures the stability of the measurements and uncompromised solar simulator performance. This guarantees that irradiance non-uniformity, spectrum, and other properties of the solar simulator remain unchanged from flash to flash".
"PV manufacturers who can show that their modules are being tested using a QuickSun all-in-one testing station are in a superior position to convince their customers that the modules are of outstanding quality, free of even the tiniest of defects, and will show uncompromised performance over their lifetime on the field", says Hyvärinen.
"Now that developers are paying more and more attention to module quality, we expect that employing the QuickSun all-in-one testing system will become one of the most important ways for the most quality-driven module suppliers to differentiate from competition", Hyvärinen continues.
