Energy analysis of hybrid solar collectors integrated in architecture

In recent years, the architectural integration of PV modules on buildings has become increasingly widespread, especially in parts of the world most industrialized, where government incentives have accelerated its diffusion. The installation of photovoltaic systems architecturally integrated into building structures certainly has advantages, if compared with systems installed in facilities separate from the building. The performance can be improved if the heat produced by the module is removed. So far, in architecturally integrated plants, the heat removed from the photovoltaic cells was always dissipated into environment. Instead in this work we tried to understand if it is possible to use, in addition to electricity, also the heat inside the buildings by means of solar hybrid collectors. Then the energy rejected from the photovoltaic conversion could be used to integrate the energy required to satisfy the building demand. The level of the techniques used by hybrids collectors on the market still needs to be tested, verified and monitored. We still need to determine combinations of materials, the influence of input and output temperature from the collector, the global efficiency and the excellent combination of heat and electricity. The purpose of this study is the analysis of solar hybrid systems architectonically integrated with the objective of maintaining high electrical performance of photovoltaic conversion, considering the amount of total energy obtained in the comparison between the water and air collectors.
