LonGi 350W Solar Panel Overview

The LonGi 350W Solar Panel (LR4-60HPB) is a high-efficiency monocrystalline PERC solar panel that incorporates advanced Half-Cut technology. This series delivers excellent performance with a module efficiency of up to 20.3%, making it ideal for residential, commercial, and industrial applications. The low LID (Light Induced Degradation) technology ensures slower power degradation over time, maintaining better performance for longer periods. With a robust anodized aluminum alloy frame and 3.2 mm coated tempered glass, it can withstand harsh weather conditions, including high snow and wind loads, ensuring durability and long-term reliability.

LonGi 350W Solar Panel Key Features:

  • High Module Efficiency: Achieves up to 20.3% efficiency, ensuring higher energy yields.
  • Positive Power Tolerance: 0~+5W positive power tolerance guarantees consistent performance.
  • Low Power Degradation: Slower power degradation enabled by Low LID Mono PERC technology, with only 0.55% annual degradation from year 2 to 25.
  • Durability: The panel can withstand 5400 Pa snow load and 2400 Pa wind load, making it highly durable in extreme environments.
  • PID Resistance: Solid PID resistance ensured by optimized cell processing and careful module BOM selection.
  • Excellent Low Light Performance: Maintains high energy output under low light conditions such as dawn, dusk, or cloudy days.
