Factory Audits and Production Supervision

Buying the right equipment

Understanding the production of PV modules is key. Our experts visit factories all around the world to conduct independent audits and assess manufacturing quality. Our reports are the basis for choosing the right manufacturer and for ensuring equipment is produced with the quality our customers expect.

With supply agreements in place, Kiwa PI Berlin’s experts monitor production in the factory and conduct independent testing to assure quality before the equipment is accepted by our customers and delivered to site.

ISO 17025 Accredited Testing Laboratory

Independent performance and reliability testing of modules

Having our own laboratories in Germany and China, and partner labs in India and Japan, enables us to assess module quality independently and swiftly. Whether the modules come from the production line or from an operating plant, our tests and reports can be relied upon by all parties involved.

Our network of laboratories are capable of offering the whole range of tests required for certification in compliance with IEC 61215 and IEC 61730.

Independent and Owner’s Engineering

From development to construction, and during operation

Our experienced engineering team provides developers with bankable yield assessments and optimal designs for their PV projects. Investors and lenders rely on us for independent site assessment and technical due diligence to protect their interests.

During the construction phase, we offer design review, construction supervision, contract management, and inspection and acceptance of the plant.

For systems that are already in operation, we can also carry out troubleshooting and troubleshooting measures on request. Our on-site inspections and testing are complemented by our laboratory and factory-related services, which provide a holistic approach to finding the right solutions.
