Energy yield

Energy yield is how much electricity a system actually produces over time, not just its rated output. Two panels with the same rating can deliver different results on site, depending on light levels, heat, shading and what sits around them.

Our bifacial panels add a second source of yield by capturing light reflected onto their rear side. How much they gain depends on the surface below them, known as albedo, and on how the panels are mounted. Heat, low light and partial shading all affect performance too, and we design our panel technologies to handle these conditions well.

Below we cover the factors that shape yield, from bifacial gain and rear shading to how yield is reflected in simulation tools such as PVsyst. These answers are most useful for installers and project designers sizing a system.
