In order to verify the quality of the products we use for our solar and battery storage projects, ENGIE US Solar utilizes a multi-faceted approach to quality assurance.
ENGIE’s Approved Vendor List comprises industry leaders within the solar energy and battery storage technology industries. We specify the highest quality products for our installation and rely upon both public and proprietary information during the vendor qualification and selection process for modules, inverters, racking, batteries and labor.
Ensuring Quality Through Onsite Audits
Key members of ENGIE’s procurement team perform regular factory audits of ENGIE’s primary suppliers in the U.S. and China. During these visits, ENGIE team members make recommendations for improvements in production lines, and review detailed plans for ongoing manufacturing performance improvement.
ENGIE team members visiting and auditing Chinese suppliers’ production facilities
Suppliers are held to best-in-class quality standards in their facilities, as well as shipping and logistics to the project site.
For new modules produced in China, ENGIE mobilizes local quality assurance partners for factory audits and in-line production monitoring. During in-line production monitoring, our partners staff the module production factory with a team of engineers during all shifts of the day for full-time supervision and statistical sampling of modules against the supplier’s own quality standards. This allows us to immediately identify, escalate and improve quality issues during the production process. ENGIE obtains daily reports of production monitoring results including any blemishes in the finished product, as well as serialized flash test results and electroluminescent imaging of the modules before they are shipped.
For all modules, both new production and purchased inventory, ENGIE works with state-of-the-art PV testing laboratories throughout the U.S. to perform destructive testing on statistical sample batches of PV modules being produced for our installations. The modules are tested for PAN file validation as well as reliability verification relative to the IEC 61215 standard and National Renewable Energy Laboratory’s Reliability Plus testing metrics. Key tests include Thermal Cycling, Humidity Freeze, Damp Heat and Mechanical Load.
We are very happy that the efficiency and economic goals we set for the ENGIE solar arrays are being realized. Those results, along with its expertise and project implementation excellence, are why ENGIE has become a long-term partner in solar development for Kimco.
