This paper introduces a recently initiated Italian national project on high innovative PV greenhouses considering different scales of experimentation as well as an interdisciplinary approach involving experts in different areas. At small scale, the light transmittance of spectrally selective solar cells devices, which focus different wavelengths on PV modules and plants, will be analyzed in order to obtain the best compromise between electricity production and photosynthesis. At medium and large scale, two greenhouses will be tested: (i) An experimental greenhouse (about 15 m2) equipped with different IoT sensors and innovative PV glasses technologies will monitor the growing environment together the energy production. (ii) Based on the results obtained in the medium scale greenhouse, some PV glasses will be used as envelope material for the renovation of a commercial-size greenhouse (about 100 m2). Both PV greenhouses will be located in a historic environment dating back to the XVIII century, the Botanical garden of Portici, which requires a careful approach to a correct integration with the landscape. Along the two years of the duration of the project is foreseen to finding the best compromise between functional characteristics (energy and food) and aesthetic ones, thus optimizing the integrated system showing the potential of innovative glasses for greenhouses.
