1. A building system, the system comprising:
a plurality of photovoltaic building components, each photovoltaic building component comprising:
a metal back plate adapted to be fixed to a building through transverse or longitudinal connection;
a glass plate having a nano-coating;
a plastic film connected to a solar cell, the metal back plate and the glass plate, wherein the solar cell is fixed between the metal back plate and the glass plate;
an automatic spraying system disposed proximate the plurality of photovoltaic building components, wherein the automatic spraying system provides a plurality of water jets to apply water over all of the photovoltaic building components;
a reverse wing device attached to the building, the reverse wing device having a plurality of reverse wings, the plurality of reverse wings spaced apart from the building to form a unobstructed gap enabling air to flow through the gap between the reverse wings and the building, each reverse wing having an upper surface and a lower surface, the lower surface having a larger surface area than the upper surface, such that the reverse wing device applies a downforce to the building during a windy weather condition; and
wherein a portion of one of the plurality of photovoltaic building components is disposed overlapping a portion of an adjacent one of the plurality of photovoltaic building components.
