Development and testing of photovoltaic pavement for heat island mitigation

Τhe present article deals with the development and testing of photovoltaic pavement for heat island mitigation. The scope of this study is to evaluate its contribution to the balance of the Urban Heat Island phenomenon. For this reason, we made a photovoltaic pavement for purely experimental reasons (dimensions 3.5x1.3m) that consists of two different voltage polycrystalline photovoltaic panels. On top of them, a triplex security glass with a nonslip silk screen, PVB standard 1.14 mm was placed. We measured their surface temperature, from morning till noon, each and every hour, for several months (summer-autumn-spring). It was proven that, in comparison with other respective asphalt street and ground measurements, it has essentially lower values. In addition, in order to find out the degree witch the photovoltaic pavement contributes to the improvement of the urban microclimate, a simulation took place.
