This work presents a new way of minimize the losses on a flat plate solar energy collector. A wind barrier is added along the collector perimeter in order to modify the flow pattern over it. This barrier creates a region of recirculating separated flow on top of the collector. This is an initial phase of the work and only winds aligned with the solar collector are investigated. In other words no influence of lateral winds is accounted for. The first experimental results proved very encouraging. It was observed a 12% heat-loss reduction in comparison with the traditional double glazing solution.
