The PV manufacturing industry’s switch to larger wafer formats is already having impacts all the way down the supply chain – some of which are still emerging today. For junction boxes that house bypass diodes and other components that keep the power flowing out of a module, handling the higher currents produced by these larger products has been a challenge requiring a quick response. Meanwhile, a notable number of failures and quality issues with junction boxes new and old suggest that the design and processing of this vital component could be in need of renewed attention.
Junction box defects can lead to heat buildup, with damaging consequences for the module
