PV Module Reliability Scorecard 2014

by Jade Jones, MJ Shiao

Two-thirds of today’s cumulative solar capacity has been installed within the last three years, and PV installations are forecasted to quadruple by the end of the decade, growing from 128.3 GW at the end of 2013 to 528.1 GW by the end of 2020. Against this backdrop of strong demand, there is growing concern that systemic quality issues will affect an exponentially increasing proportion of PV projects. Yet, so far, the extent of the module reliability problem has been largely misinterpreted and ill-understood. With full-life field data on today's products years away, and without access to publicly available data comparing long-term module reliability by vendor, how can buyers and investors factor quality into their procurement discussions?

The PV Module Reliability Scorecard aims to address this critical problem. The Scorecard defines a reliable module as one which can deliver its promised and guaranteed energy yield over its lifetime. With its supplier-specific performance analysis, the Scorecard is another tool for investors' and developers' quality-backed procurement strategies.
