Photovoltaic Balance of System Component Testing and Certification
Ensure quality and reliability in the balance of system.
The balance of system (BOS) covers all the electrical and mechanical components of a photovoltaic (PV) system other than the PV modules. BOS component quality is essential for the safety and performance reliability of PV systems throughout their lifetime.
PV module power will degrade if the BOS components are not integrated within the entire installation. In addition, the BOS components must withstand harsh weather conditions. Manufacturers of BOS components need to be aware of product-related design and safety requirements to ensure that their products comply with national and international standards and codes.
TÜV SÜD has a long standing expertise and strong background in PV BOS product safety and performance requirements and offers testing and certification services to help ensure compliance to the relevant requirements.
TÜV SÜD provides support with BOS component testing during research and development (R&D).
We offer PV laboratory qualification according to ISO/IEC 17025, which comprises verification of scope and accreditations, testing structure and laboratory layout, operations and maintenance requirements.
