itel 550w Solar Panel

550W High-Efficiency PV Module

Key Features:

High Efficiency: 21.29% module efficiency with 144 N-Type Mono cells (182*9’1mm), ensuring superior energy output.
Temperature Resilience: Low Pmax temperature coefficient (-0.29%/°C) minimizes power loss in high-heat conditions.
Durability: Certified for extreme weather (2400Pa wind load, 5400Pa snow load) with anodized aluminum frame and tempered glass.
Stable Output: Advanced technology reduces LiD/LeTiD degradation, maintaining long-term performance.
Low-Light Performance: Generates electricity 1 hour longer at dawn/dusk, maximizing daily energy yield.

⚠ Caution: For it to power appliances, the Panel should be connected to an inverter and a battery (the battery is optional for night power supply), the panel is not all in one system.

“Great panel for the price! Efficiency is as advertised, and the IP68 rating ensures durability. Only minor gripe: the cables could be slightly longer for large-scale arrays. Still, an excellent value for industrial use.”
