itel Energy 620W N-Type Bifacial Monocrystalline Solar Panel

Description

The itel Energy ISP-620W-G1 is a high-output 620W N-Type TOPCon bifacial monocrystalline solar panel, designed for residential, commercial, industrial and utility-scale solar installations. It uses 132 half-cut cells, has 22.95% module efficiency, and a maximum system voltage of 1500V DC.

Key Specifications

The manufacturer/distributor information identifies the 620W model as a 132-cell N-TOPCon bifacial module with 22.95% efficiency.

☀️ Main Features

620W High Power Output
Each panel provides up to 620W of rated power, allowing you to build a large solar array with fewer panels.

N-Type TOPCon Technology
The N-Type TOPCon design provides high efficiency and is designed for strong long-term solar generation.

Bifacial Solar Technology
The panel can generate power from both its front and rear surfaces. Under suitable installation conditions, current product information indicates approximately 5–23% additional rear-side yield. Actual gain depends on mounting height, ground reflectivity and installation design.

22.95% Efficiency
The high module efficiency makes the panel particularly useful where available installation space is limited.

IP68 Protection
The junction box and connectors are designed for outdoor environments, with IP68 protection.

🔋 Example Solar Array Sizes

• 5 panels × 620W = 3.10kW
• 10 panels × 620W = 6.20kW
• 20 panels × 620W = 12.40kW
• 50 panels × 620W = 31.00kW
• 100 panels × 620W = 62.00kW
• 120 panels × 620W = 74.40kW

For a 50kW itel 3-phase hybrid system, 100 × 620W panels would provide 62kW of installed PV capacity, while 120 panels would provide 74.4kW, close to the inverter’s stated 75kW maximum PV input.
