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.

it’s been 6 month since i went off-grid with these panels. so far so good. tip: If you plan to do it, you need good batteries. just don’t buy them in advance like i did. i stored a battery in garage and didn’t use it and now it works much worse than others.

I bought these panels almost a year ago. Chinese ones are always cheaper, but their quality is all right to me. There was a huge tornado here in the end of the spring, winds were rough, but the panels surprisingly survived all that. I’m quite impressed, thx!

Very good service. The panels look good and are quite cheap. I wouldn’t say that they are anything special, but they do their job. Good performance even when there isn’t a lot of sunlight.
