These numbers are typical for 550 W 144-cell half-cut PV modules and are consistent with similar modules in the market. Confirm the exact datasheet for the Longran PV-LR-M72-550W for precise values.
Delivers up to ~550 W under Standard Test Conditions (STC), making it suitable for systems requiring higher energy yield per panel.
Uses half-cut cell technology to reduce resistive losses and improve performance, especially under partial shading.
Cells made from high-purity silicon deliver higher efficiency compared to polycrystalline panels.
Ideal for limited spaces since you get more power per square meter.
Anodized aluminum frame and tempered glass protect the panel from outdoor conditions.
IP68 junction box with bypass diodes enhances safety and performance in varied weather.
Compatible with most mounting systems for rooftops and ground installations.
Works with typical solar inverters and MPPT charge controllers covering the voltage/current range. Solar System BD
