Current affairs

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.
