Renel Energy & Power Engineering undertakes the procurement of equipment and the installation service of the pilot facade of the PE of Grevena within the framework of the PLUG-N-HARVEST project. The pilot facade will be applied to the southeast and west surfaces of the building in order to achieve the maximum electrical and thermal energy gains, on an annual basis. In the building, there is an already installed stand-alone photovoltaic system of 60 kWp with an on-line monitoring system combined with other energy saving measures (air-to-water heat pump, LED lighting, compensation capacitors and a solar charging station for electric bicycles)
