Sunway 132cells 210mm 680W 700W Monocrystalline HJT Solar Panel

HJT Technical Advantage 1.The HJT cell is designed with conductive TCO surface and insulation-free layer, so there is no build-up surface layer charge. 2.Compared to PERC module, HJT features lower power temperature coefficient and higher output power.It is about 4.9% more efficient in power output than PERC module under 60℃ operation temperature.  3.The effective power generation time of HJT is 11.07% more than the effective power generation time of conventional cells.ELECTRICAL PARAMETERS @ STCMax.

Higher bifaciality allows more energy yield on the back.Generally, it enables 5%-30% energy gain on the back, depending on the factors such as ground reflection, region type etc.HJT modules adopt the production technology of low-temperature ribbon and low temperature flux, bring much lower damage for the cells, granting reliability and performance comparable to that of PERC.
