The clearance between the module rows is unused in open space photovoltaic plants and will generally be no longer utilized.
At the same time solar energy is reaching the surface. This energy is not being utilized. Due to this sophisticated technique of reflective areas in these clearances, a part of the solar radiation is additionally reflected on the subsequent module row.
Due to geometrical factors, the increased energy yield will occur especially in the morning and evening hours of winter and summer. This has the major advantage that the plant itself must not be modified and energy production is continuing
