Module Browning

Panel Browning

Browning or yellowing of PV panels is a result of the ethylene‚Äźvinyl acetate (EVA) copolymer encapsulant degrading. The EVA protects the panel cells from moisture and UV radiation.

Panel browning or yellowing can result in real power losses in the panel, with reduction of power in some cases over 50% of the initial power output of the panel. Other effects of browning are additional heat absorption of the panel which accelerates the browning and the mismatch effect. Any panels affected by browning should be replaced. They cannot be repaired. 30 North can perform an in depth analysis of your system with our state of the art testing equipment to accurately measure the performance of your system. 30 North can also assist you with your warranty claims and system repairs.

The cost to repair and upgrade this system to meet current Australian standards will exceed its original purchase price! Unfortunately for this client the retailer who sold this system has gone out of business and any warranty claim on the installation is no longer valid. The product does carry a warranty; however, the claim needs to be made with the Chinese manufacturer, based in China. A cheap and very nasty system!
