aleo performs the EL test on every cell and on strings directly after the soldering process. Each cell in each module is tested twice before lamination process!
They double the IEC required tests:
•Dampheat x 2000hrs
•Thermal cycles x 400 cycles
•Humidity EVA and backsheet freeze cycle: x 20
•UV tests: x 20
Each panels can also handle 8000Pa front pressure, extra duty against Hail, Snow and Cyclone
aleo is precise on frame construction and adjusting. No tolerance +/- X% in dimensions is accepted. Panels mounted on a roof or on ground need to be 100% aligned in terms of mechanical stability and aesthetical result.
Finally when the module production is completed, aleo takes a real electroluminescence photo of each module.
