Longi Solar Wins First Place In TÜV Rheinland “PV Module Outdoor Power Generation

LONGi Solar won top place in the PV Module Outdoor Power Generation category at the 5th TÜV Rheinland “All Quality Matters” PV Congress in Suzhou, China, on March 21.

The company won the top spot this year after winning the “PV Module Power Generation Simulation” award for the previous two consecutive years.

TÜV Rheinland“ All Quality Matters”first added the test project of“PV Outdoor Power Generation”, which aims to verify the actual power generation capacity by recording long-term PV module data in the most authentic power generation environment. The award has won the recognition and support from industry experts, authority institutions, owners and manufacturers.

In order to ensure data accuracy in the “PV Module Outdoor Power Generation evaluation section, TÜV Rheinland randomly selected 5 modules out of the 1000 mass production modules (serial number) provided by the participants for the test.

The Rheinland data package is then formed based on comprehensive performance test data including parameters like initial stability, STC/SR, temperature coefficient, angular response, temperature and radiation combination performance.

Finally, participants optimized the installation method in TÜV Rheinland' s outdoor test site, in  Cologne, Germany, and calculated the 12-month actual outdoor power generation for authentic pranking results for PV Module Outdoor Power Generation based on the formula of the annual power generation of the modules/the reference power of the participating modules (kwh/Wp).

According to the evaluation data, LONGi Solar’s monocrystalline  module ranked first clocking in the highest power generation even though, in an outdoor evaluation, the corresponding low light intensity, low attenuation and stability of the modules should affect their final power generation capacity. LONGi Solar brought the power generation performance of monocrystalline module to new heights through technical improvements and research and development.

Outdoor demonstration is the most realistic performance of module products in practical applications. Winning the first place in TÜV Rhein's “PV Module Outdoor Power Generation Test” proves the high quality and reliable performance of LONGi Solar’ s monocrystalline modules.

Lv Jun, vice president of LONGi Solar said during his acceptance speech: “LONGi Solar has always insisted on creating superior products and services for customers. The prize comes from objective measurement, indicating the recognition of the high power generation capacity of our mono-crystalline modules. It not only facilitates customers to trust our products, but also strengthens our confidence and determination to continue developing high efficiency products.”
