2021 PV Module Reliability Scorecard

Next Steps

It is time for sustainable growth

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.

Continuing on our decade+ mission to deliver empirical data that drives the adoption of reliable solar power, PVEL has partnered with Kiwa, a global testing, inspection and certification firm, to make our data matter for every solar power plant on every continent.

A Message from Our New Partner, Kiwa Group

We’re proud of our new partnership with PVEL because it offers a synergistic effect for our customers as demand for solar power grows.

PVEL’s North American presence brings Kiwa close to our customers on all continents – just as Kiwa’s global footprint brings PVEL closer to its partners around the world.

Together, we are increasing our contributions to the advancement of solar power and toward a better, more sustainable world.
