Take the right next step for you.

Our mission is to support the worldwide PV module market by generating data that accelerates adoption of solar technology. Learn how you can benefit from all PVEL offers.

PV Module Buyers, Asset Owners, & Investors

Researching top-performing PV modules is only one aspect of risk mitigation for solar PV assets. PVEL supports downstream project stakeholders at every step of project development, construction, and operation.

Below are PVEL’s recommended best practices.

Procure Top-Performing Bills of Materials

Each Top Performer listed in the Scorecard represents a unique bill of materials (BOM). PVEL supports its network of downstream partners with BOM information for the products we test. Our partners use this data to specify BOMs in PV module supply agreements.

Audit and Monitor Factories

Downstream project stakeholders should require factory audits, or independent inspections of a manufacturer’s production lines, before PV module procurement to ensure suppliers meet quality standards. Monitoring PV module production during the manufacturing process also helps prevent quality issues in the modules produced for a specific project.

Validate Quality

Testing statistically significant samples of PV modules during module production helps buyers identify and remedy quality issues in the modules being deployed to their sites. This process, known as batch testing, requires shipping a randomly selected subset of PV modules from the factory to PVEL for assessment.

Verify Performance

Test PV modules upon delivery to the project site and prior to system commissioning to ensure that damage has not occurred during transportation or installation. PVEL provides on-site testing for utility-scale solar projects. When performance or reliability issues arise in the field, PVEL’s mobile response team is available to diagnose problems and provide guidance for remediation.
