Photovoltaic Product Test and Certification

A safe, high-efficiency and running well PV power plant relies on good quality PV components. The effective recognition of PV components is often ignored by the end users, and this circumstance results in a great hidden danger in each stage.

DEKRA not only supports manufacturers as well as end-use customers. We participate into the process in the first stage. We provide our service regarding to international standards, and strictly supervise the process from the design of PV components, material selection to production. We provide the great support to have risk-free operation of PV power plant.

PV inverters convert DC voltages generated by photovoltaic modules to AC voltages, and can be feed to commercial public distribution networks, or used in off-grid system. PV inverter is the core component of photovoltaic power generation systems. Inverters, as the most electronic and electrical components used in photovoltaic power station, have relatively poor reliability and easy to failure. Increasing the reliability of the inverter can significantly improve the reliability of the whole power station, resulting in a significant increase in the average annual electricity generation of photovoltaic power stations.

DEKRA owns comprehensive photovoltaic power station services which allow us to explain the risks associated with customer management of the construction and operation of photovoltaic power stations. With DEKRA’s technical knowledge and worldwide testing network, from the planning stage to the final acceptance stage, DEKRA can perform design assessment, manufacture supervision of key equipment, performance testing, O&M certification, risk assessment, and safety training services to provide one-stop photovoltaic power station services to developers and operators.
