itel 620W Bifacial Mono PERC Solar Panel — Single Unit

Harvest More Sunlight — From Both Sides

The itel 620W Bifacial Mono PERC Solar Panel is not your ordinary solar panel. It captures sunlight on its front face and reflected light on its rear face, delivering up to 25% more energy than a traditional monofacial panel of the same rated wattage.

Whether you mount it on a white rooftop, a ground-mount rack over grass, or a pergola, the bifacial design turns wasted light into usable power.

Why Bifacial Wins Every Time

• Up to 25% more total yield compared to monofacial panels of the same wattage
• Dual-glass construction — 30-year structural life; glass is more weather-resistant than polymer backsheets
• Better heat tolerance — lower temperature coefficient means the panel loses less output per degree of heat
• Anti-PID, anti-hot-spot — quality cells with tight binning
• Salt-mist and ammonia-resistant — great for coastal and agricultural installations
• Snow and hail rated — 5400Pa mechanical load

Technical Specifications

Ideal Applications

• Residential rooftop systems (white or light-coloured roofs)
• Ground-mount arrays over grass or gravel
• Commercial rooftop installations with high albedo
• Solar carports and shade structures
• Agricultural solar pumping stations
• Off-grid community power systems

Installation Tips

1. Height matters for rear-face gain: mount at least 1 m above the roof/ground for maximum bifacial effect.
2. Reflective surfaces boost output: a white membrane roof can add 15–25% more yield.
3. Use a compatible inverter: with Vmp ~39.2V, this panel pairs perfectly with 48V hybrid inverters (string of 2 in series = ~78V).
4. Torque to spec: 16–20 N·m on frame bolts; over-tightening can crack the glass.

Solar panels are not commodities. A 620W bifacial panel from a tier-1 supplier will outproduce and outlast a "looks the same" clone by 3× over its lifetime. This is a purchase you make once — make it right.

Buy with confidence. Every itel panel ships with a serial number and a printed warranty certificate. Bulk pricing available for orders of 10+ panels.
