LONGi wins TÜV Rheinland’s highest A++ Energy Yield rating for its bifacial modules

LONGi, the world leading solar technology company, was awarded the A++ Energy Yield Rating Label for desert climate conditions by TÜV Rheinland for the excellent power generation performance of its bifacial modules. The A++ label is the highest among the seven grades of TÜV Rheinland’s rankings and validates the outstanding performance of LONGi’s PERC bifacial modules in desert conditions.

The A++ ranking label awarded is based on the one-year (2018.09~2019.09) power generation of its bifacial modules in Jeddah, Saudi Arabia and Chennai, India.

The pilot project in Saudi Arabia is located at the King Abdullah University of Science and Technology School in Jeddah, with the surface being sand.

The annual power generation of LONGi’s bifacial PERC modules reached 1713.8kWh/kWp/year (system efficiency 95.0%), with a bifacial gain of 11.4%.

The pilot project in India is located in Chennai, on the country’s east coast, on white gravel surface. The annual power generation of the bifacial modules here reached 1370.6kWh/kWp/year (system efficiency 99.3%), with a bifacial gain of 19.3%.
