DEKRA One Stop Solution of Photovoltaic Industry

Photovoltaic Product Test and Certification

Since the Industrial Revolution, the energy mix of most countries across the world has become dominated by fossil fuels. This has major implications for the global climate, as well as for human health. To reduce CO² emissions and local air pollution, the world needs to rapidly shift towards low-carbon sources of energy renewable technologies.

Renewables are the backbone of any energy transition to achieve net zero. As the world increasingly shifts away from carbon emitting fossil fuels, understanding the current role renewables play in the decarbonisation of multiple sectors is key to ensuring a smooth pathway to net zero.

As an international expert organization, DEKRA offers a wide range of comprehensive services to address the challenges of the solar market based on national and international standards as well as industry and customer requirements. We have comprehensive experience and professional team providing supply chain services for PV projects of different capacities. Our goal is to streamline and manage the testing and certification processes across international boundaries and improve both global access and time to market for our customers.

PV modules are important components in PV power plant. Whether in open fields, deserts,on the roofs, different environments put higher demands on the quality and reliability of PV modules. DEKRA is able to provide a wide range of services for PV modules, including crystalline silicon, thin-film, integrated building and concentrated PV modules.

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.
