Chinese PV module maker Longi has debuted its new EcoLife series of solar panels.
The EcoLife series features the company’s back contact technology and is billed as a premium lifestyle brand for customers on the residential market “who value quality, independence and lasting impact”.
The panels are available in a compact 54-cell format. The series features the company’s flagship all-black bifacial module, LR7-54H7BB, of up to 505 W and with an efficiency of 24.7% and its premium all-black bifacial module, LR7-54HVBB, of up to 485 W and with an efficiency of 23.8%.
Both modules have a larger installed capacity and quicker system payback period than TOPCon modules, according to the company.
The company also said the EcoLife series reduces power degradation by 70% compared to TOPCon modules under the same shaded conditions. The result is buoyed by a built-in diode tech that ensures only 8% efficiency loss when a single cell is shade.
The series has a temperature coefficient of -0.24%/C.
Longi also recently unveiled a new bifacial n-type HJT solar module based on back-contact architecture.
