LONGi Solar Field Tests proved average bifacial gain of 19.9% of LONGi Solar Hi-MO2 bifacial PERC Mono when compared directly with Hi-MO1 monofacial with the same mono PERC cells. The bifacial gain peaked as high as 25.8%.

Test conditions: 

1st Sep to 10th Nov 2018 in Hainan, China. The Sep dataset was captured from 8:45am-4:55pm while Oct and Nov data was 8:45am-3:55pm. Surface is white painted ground.

Hainan’s environment near the coast and perennial humidity requires salt-mist corrosion certification for PV modules that guarantees performance over their lifetime.

The 5th“All Quality Matters”Ceremony organized by TÜV Rheinland was successfully inaugurated on 21st March in Suzhou. Ginlong (Solis) participated in the competition of medium power group and was awarded the first place as “PV Inverter for Commercial Use (20kW)”.

While receiving the award, a representative of Ginlong (Solis)Mentioned: "We thank TÜV Rheinland for awarding Ginlong (Solis), this is the biggest recognition and praise for our technical innovation.We have grown into the world's leading group of inverter manufacturers with excellent product quality and performance, as well as with the maximum customer satisfaction and market support. As a representative of technological innovation in the industry, Ginlong (Solis) broke through the technical bottleneck as early as 2016 and took the lead in launching a new generation of 4G inverter technology platform, which helped promote the diversified development of the high-end market of tandem inverter.This 20kW model represents Medium Power Series of Ginlong (Solis). It is the balance point of all kinds of designs found on the existing 4G technology platform. With the decline of domestic photovoltaic subsidies, the capacity of household photovoltaic system increases gradually. More and more commercial medium power inverters are used in larger capacity photovoltaic systems. We look forward to execute with passion in the application market with TÜV Rhineland's awarding.

Extended Reading: TÜV Rhineland, founded in 1872, is the world's leading third-party authoritative testing agency. In the global new energy industry, it has strong strength in testing, certification and technical evaluation, and has become the synonym of "safety and quality" in the hearts of global consumers and enterprises.
