Installation & Performance Tips

To maximize the performance of your LONGi Hi-MO LR7 bifacial solar panels:

• Install in locations with high albedo (reflective surfaces like sand, white roofs, or snow) to maximize bifacial gains
• Ensure adequate mounting height to allow light reflection to the rear side
• Use compatible inverters rated for 1500V DC system voltage
• Clean panels regularly to maintain optimal performance, especially in dusty environments
• Monitor system performance through your inverter's monitoring platform

Why LONGi Hi-MO for Pakistan?

As demand for renewable energy grows across Pakistan, LONGi Hi-MO bifacial solar panels are increasingly preferred for utility and commercial projects. The LONGi 620W Bifacial Solar Panel offers exceptional value, providing higher efficiency and better returns on investment compared to conventional panels. For large-scale projects, the LR7 series delivers reduced LCOE (Levelized Cost of Electricity) and maximizes land use efficiency.
