As climate change propels nations and companies toward aggressive clean energy targets, the expansion of solar power must continue. But rapid growth is not without risk. As PV module manufacturing capacity increases, so do mistakes on production lines.
Technical advances are raising expectations for energy yield in the field. These expectations cannot be fulfilled if manufacturers overlook quality controls and buyers do not require these controls.
The high failure rates noted in this year’s Scorecard, particularly for junction boxes, prove that independent testing remains necessary.
