With 182mm, 210mm, 210R solar cells, TOPCON PV modules offer unmatched quality and performance.
The application of multi-busbar(MBB) half-cut cell technology brings stronger resistance to shade and lower risk of hot spot.
Strict control on raw materials and process optimization of high efficiency TOPCon ensure better resistance against PID of PV module.
Through harsh weathering tests of sand, dust, salt, mist, ammonia, etc., to get stronger weather resistance in outdoor environment.Lower oxygen and carbon content result in lower LID. By series and parallel design to reduce the series RS and achieve higher power output and lower BOS cost lower temperature coefficient and lower operating temperature can ensure higher power generation.
