Solar and Photovoltaic (PV) Services

Your experienced independent partner for testing and supply chain management services addressing the solar industry

Photovoltaic technology has undergone a tremendous transformation over the last few decades particularly in increased efficiency, lower system prices and PV technology adapted to various areas of application. New installation markets have emerged, while pressure to further reduce prices and improve the functionality of system components has intensified. The need to accurately predict and assess the performance, reliability and durability of entire PV power plants has become critical.

We provide up-to-date solutions to improve the safety, reliability and quality of individual Balance of System (BoS) components and of PV power plants. As an independent third party, we have the trust and respect of investors, owners and lenders.

With over 35 years of experience, we offer a global presence, industry expertise and a wide range of comprehensive services to address the challenges of the solar market. These services include testing and certification of PV modules and components, supply chain management, buyers’ services and independent engineering for PV power plants, supporting the PV power plant value chain. We maintain a global network of laboratories in all major solar hubs.

New test specification: PV products for 2000 V nominal voltage

As the performance of PV modules continues to increase, operators are now demanding approval of PV modules with 2000 V nominal voltage. However, international standardization currently only covers the requirements for PV modules and their components with a rated voltage of up to DC 1500 V. TÜV Rheinland has closed this gap by developing several internal testing specifications (2 PfGs).

Since March 2023, we are offering testing of PV connectors (2 PfG 2925) and PV junction boxes (2 PfG 2928) in addition to testing of PV modules. This will increase the safety of PV attached components. The internal test specifications are based on the international standards IEC 62852 (PV connectors) and IEC 62790 (PV junction boxes) and contain additional requirements for use in systems with DC 2000 V nominal voltage. Hence, the installation of these components is only permitted in areas that comply with the requirements for industrial sites according to IEC 61000-6-4 (for Class II components) or the requirements for restricted access areas ("restricted access area", for Class 0 components).

Prospect: An internal test specification for PV cables for use in 2000 V systems is currently under development.
