Longi Solar LR4-72HBD-435M 435w Mono Bifacial Solar Panel

LONGi's high-efficiency modules have been deployed around the globe in just about every application possible across a wide range of climate conditions, including grasslands, farmlands, deserts, mountains, lakes and reservoirs, residential and commercial rooftops. The solar modules benefit customers and communities with advantages such as greater efficiency and performance, lower light degradation and better reliability. Front side performance equivalent to conventional low LID mono PERC. Bifacial technology enables additional energy harvesting from rear side (up to 25%). Glass/glass lamination ensures 30 year product lifetime. Solid PID resistance ensured by solar cell process optimization and careful module BOM selection. Reduced resistive loss with lower operating current.

Features

• Half-Cell: The power output of a bifacial half-cell module increases and energy yield is higher under high irradiance conditions because of low working current
• Mechanical Load: Framed module, front/back side maximum static loading 5400/2400 Pa, makes it suitable for tracker mounts
• High Rating: Glass and junction box, with high voltage grade, supports 1500V systems
• Bifacial Energy Yield: Additional power generation from the backside of bifacial modules increases the overall energy yield, which has been verified by customers and third-party testing organizations
• Low Degradation: Anti-LID, anti-PID, 1st year degradation ≤2%, linear degradation ≤0.45%/year
• Standard Module: Our standard module is fully compatible with mainstream inverters and trackers, with no system matching issues
• Gallium-doped Technology: Gallium-doped technology overcomes LID degradation and guarantees the long-term power generation of the module
• 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%
• Adaptable - Solid PID resistance ensured by solar cell process optimization and careful module BOM selection
• Reduced resistive loss with lower operating current. Higher energy yield with lower operating temperature
• Reduced hot spot risk with optimized electrical design and lower operating current
