Adhering to the core concept of “Customer Value As the Center”, LONGi runs through the “LONGi Lifecycle Quality” in every link of product production and application from component design to mass production and after-sales support, so as to ensure the reliable landing of terminal value. LONGi is on the innovation road to change the world energy pattern. Facing the application needs of various industries and multiple scenarios, LONGi provides comprehensive scenario solutions.
LONGi’s high-efficiency PV modules are widely used all over the world, from alpine grasslands to desert wastelands, and from ponds and vegetable beds to household dwellings. LONGi’s ultra-high-value PV module products continue to benefit customers and local economy with its advantages of “higher power, lower degradation and higher reliability”.
The PERC cell has a passivated rear side and a laser grooving process, which significantly improves the cell efficiency.
Bifacial PERC
For a bifacial PERC cell, the Al back surface field is replaced by Al grid, hence render the majority of rear side transparent which enable the cell to absorb light and generate electricity from both sides.

High Energy Yield
Outstanding low irradiance performance, low power-temperature coefficient, low operating temperature, all these technologies lead to a high energy yield.
Warranty
Based on the advanced mono wafer and anti-LID technology, LONGi offers a first-year power warranty of ≥98% for PV modules.

Bifacial Power Generation
The energy yield of bifacial module can be influenced by albedo, height of module, GCR and DHI etc. Installation height of bifacial module is recommended to be higher than 1m. Shading from bracket and junction box should be avoided. At present, the power generation of bifacial module on fixed brackets and single axis tracker can be simulated with PVsyst. Investors can determine the DC/AC ratio of bifacial module system to minimize the LCOE.
