The two-sided effect depends on three key factors: the reflectivity of the surface beneath the panel (albedo), the mounting height above the surface, and the tilt angle. On flat or light-colored surfaces, the gain from the rear side will be more noticeable. Mounting on trackers or at a slight elevation also provides additional benefits.

The module is designed to withstand the mechanical loads typical of open installations and can withstand hail and wind. The junction box has an IP68 rating, reducing the risks associated with dust and moisture ingress. The temperature dependence of the power is taken into account in the technical specifications, allowing for predictable generation under real-world climate conditions.

The module is suitable for ground stations with reflective surfaces, rooftop arrays with limited space, and systems with trackers. Additional generation from the rear side increases the total energy generated per module.

A long manufacturer’s warranty allows for predicting system operation for a decade in advance and planning for a return on investment without additional risks.
