Key Advantages
Unrivaled Efficiency: The 190W model achieves 19.95% efficiency—among the highest in its class—maximizing energy harvest for limited space.
700V System Compatibility: Supports large-scale series connections (e.g., 30+ panels) for utility-grade or industrial off-grid systems, reducing wiring costs.
Heavy-Duty Durability: 3.2mm tempered glass + anodized aluminum frame resists impact, corrosion, and UV degradation. IP67 junction box (waterproof to 1m for 30 minutes) and 5400Pa front wind load / 2400Pa rear snow load ensure reliability in harsh environments.
Scalable & Future-Proof: Customizable cable lengths (90cm standard) and MC4 compatibility simplify integration into complex PV arrays.
Frequently Asked Questions
Can this panel charge a 24V battery?
Yes! The Vmp (18.79-19.06V) is ideal for 24V battery systems (with a compatible charge controller).
How many panels fit on one pallet?
36 panels per pallet (dimensions: 1295*1100*885mm; weight: 385kg).
Is it suitable for coastal areas?
Absolutely. The IP67 junction box and corrosion-resistant aluminum frame withstand salt, moisture, and extreme weather.
Application Scenarios
Large Off-Grid Homes: Primary power for remote cabins, farms, or eco-resorts
Commercial Rooftops: Small businesses, warehouses, or agricultural facilities seeking energy independence
Telecom & Utilities: Powers remote cell towers, weather stations, or grid-tied backup systems
Mobile Applications: Heavy-duty RV solar systems, large boats, or mobile command centers
