The integration of PV modules into building facades or roof could raise PV module temperature that results in the reduction of electrical power generation. Lowering operating temperature of PV module is important in this respect, and PV module temperature should be considered more accurately, for building-integrated PV(BIPV) systems in predicting their performance. This paper describes a BIPV solar roof design and verifies its performance through experiment In relation to the effect of ventilation in space between PV module and roof surface. The results showed that the ventilation in the space had a positive effect in lowering the module temperature of the BIPV solar roof that enhanced the performance of its electricity generation.

Building-Integrated Photovoltaics (BIPV) is a photovoltaic (PV) technology which can be incorporated into the roofs walls of both commercial and domestic buildings to provide a source of electricity. BIPV systems can operate as a multi-functional building components, which generates electricity and serves as part of building envelope. It can be regarded as a new architectural elements, adding to the building's aesthetics. Applying PV modules on roof has an advantage over wall applications as they seem to receive more solar radiation on PV modules. There are various types of PV applications on building roofs: attached, on-top and integrated. This paper describes the classification and characteristics of PV applications on roofs.

The heat from PV modules should be removed for better electrical performance, and can be converted into useful thermal energy. A photovoltaic-thermal(PVT) module is a combination of PV module with a solar thermal collector which forms one device that produce thermal energy as well as electricity. In many studies various water type PVT collectors have been proposed in effort to increase their electrical and thermal efficiency. The aim of this study is to evaluate the heating performance of heating system combined with PVT collectors that on integrated building roof. For this study, the BIPVT system of 1.5kWp was installed at the experimental house, and it was incorporated with its heating system. From the experimental results, the solar fraction of the heating system with BIPVT was 15%. It was also found that was analyzed that the heating energy for the house can be reduced by 47%, as the heat gained from BIPVT system pre-heated the water used for heating system.
