A good combination: Tracking of the sun in polar axis and bifacial photovoltaic modules

The incident irradiance on both faces of a panel with bifacial modules (albedo collectors) and tracking of the sun in the polar axis has been calculated by a mathematical model, which has been later evaluated through experimental means, utilizing the concept of view factor between two surfaces simpl...

Description
Summary:The incident irradiance on both faces of a panel with bifacial modules (albedo collectors) and tracking of the sun in the polar axis has been calculated by a mathematical model, which has been later evaluated through experimental means, utilizing the concept of view factor between two surfaces simplified with the introduction of the weighted view factor. The comparison between a panel of these characteristics with a conventional one (monofacial and static) has provided a significant finding: 1.7 times greater annual energy collection. This makes the bifacial module panel with polar axis tracking a good combination.
