66HL4M-BDV 605-630W High-efficiency Monocrystalline Silicon Bifacial Half-Cell Solar Panel

Features

Overview

N-type modules using Tunnel Oxide Passivating Contacts (TOPCon) technology feature lower LID/LeTID degradation and better low-light performance.
N-type modules using HOT 3.0 technology offer improved reliability and power generation efficiency.
Bifacial power generation gain increases with rear-side light exposure, significantly reducing LCOE.
The complete module is certified for a maximum tested static load of 5400􀀀Pa on the front side and 2400􀀀Pa on the rear side.
Better light utilization and current collection capability effectively increase product power output and reliability.
Through optimization of cell production technology and material control, the probability of degradation caused by PID (Potential Induced Degradation) is minimized.
