19.5% Panel Efficiency
LONGI 355W LR4-HPB performs at 19.5% efficiency, ensuring greater energy yields. It shows outstanding power output in low light conditions, such as dawn, dusk and on a cloudy day, with guaranteed positive power tolerance of 0~ 5W.
Quality and Reliability
All LONGI panels undergo a number of stringent quality control tests. Solid PID resistance is ensured by solar cell process optimisation and careful module BOM selection. LONGI 355W LR4-HPB is designed to withstand front side maximum static loading of 5400Pa and rare side maximum static loading of 2400Pa.
Slow Power Degradation
Slow power degradation is achieved due to Low LID Mono PERC technology. First year the panel degrades <2%, and 0.55% over the next 24 years.
Enhanced Frame Design
The module’s 35 mm frame design provides easy installation and ensures robust mechanical strength. This module passed rigorous ammonia and salt mist resistance tests.
25-Year Power Output Warranty
LONGI 355W LR4-HPB comes with a 12-year product warranty for materials and processing and 25-year warranty for extra linear power output.
