Tracker-mounted bifacial PV is the most disruptive solar yield improvement technology since the introduction of the modern tracker. While designing and building a bifacial PV power plant is not much more difficult than building a monofacial power plant, modeling and optimizing a bifacial plant is far more complex. For bifacial to achieve its market potential, investors and financiers must be able to confidently predict bifacial performance. The ability to accurately model and measure bifacial performance is crucial.
