Leader and pioneer in testing and quality control inspection


Testing & quality control inspections

Quality and performance are the basis for long-term success.

“We have developed the Enertis’ Quality Assurance Program (EQAP), which means minimum risk / cost and maximum energy production.”

EQAP covers every stage of the project’s life cycle, including the vendor’s qualification and contract terms for all the equipment and works.

We remain independent from manufacturers of modules and other components to offer photovoltaic power plant owners and operators a whole range of tailored service packages of testing and quality control inspections.

Enertis Applus+ has its own laboratories and module quality procedures accredited by the Spanish National Accreditation Body (ENAC), which is a full member of the International Laboratory Accreditation Cooperation (ILAC).

This ENAC accreditation with NÂș 811/LE 1661 credits the tests mentioned in PV Mobile Lab, In-Lab Testing and On-Site testing services, are performed following the current international guidelines including the criteria defined by the standard UNE-EN ISO/IEC 17025:2017 (CGA-ENAC-LEC).
