Product Name: Tier1 Solar Panel Longi Brand for Pump System Perc Double Glass Solar Panel 445W 450W Model NO.: LR4-72HBD-440W Material: Monocrystalline Silicon Certification: UL, CE Condition: New Application: Agriculture Number of Cells: 144 Warranty: 25 Years Trademark: LonGI Transport Package: Pallets Specification: 2094*1038*35mm Origin: China HS Code: 85414020 Product Description PRODUCT DEscriptION:Front side performance equivalent to conventional low LID mono PERC:-High module conversion efficiency (up to 20.9%).-Better energy yield with excellent low irradiance performance and temperature coefficient.-First year power degradation<2%.Bifacial technology enables additional energy harvesting from rear side(up to 25%).Glass/glass lamination ensures 30 year product lifetime ,with annual power degradation <0.45%,1500v compatible to reduce BOS cost.Solid PID resistance ensures by solar cell process optimization and careful module BOM selection .Reduced resistive loss with lower operating temperature.Higher energy yield with lower operating temperature.Reduced hot spot risk with optimized electrical design and lower operating current.Bifacial Power Generation:The energy yield of bifacial module can be influenced by albedo, height of module, GCR and DHI etc. Installation height ofbifacial 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.PACKING & DELIVERY
