DNV GL, the world’s largest independent renewables testing, advisory services and certification company, has released its third annual PV Module Reliability Scorecard report, presenting a thorough analysis of PV module performance based on laboratory environmental testing.
The study brings a consistent set of evaluation criteria to indicate long term PV module performance and covers most leading manufacturers active in the market today. The report addresses the need for the lack of reliable and independent publicly available extended environmental testing results. As new technologies emerge and are introduced into the market, advanced testing is critically needed to assess long term performance and look beyond just lowering costs.
Of the more than 300 GW of installed global PV capacity, 78% has been in the field for less than five years. It will be more than 20 years from now before actual lifetime field data for the majority of today’s capacity can be gathered.
The DNV GL PV Module Reliability Scorecard aims to address this critical challenge. With its supplier-specific performance analysis, the Scorecard can help investors and developers generate quality-backed procurement strategies to ensure long-term project viability based on 3rd party empirical data.
