Are solar irradiation resources and BIPV potential of residential buildings?

Building integrated photovoltaic (BIPV) is a promising solution for providing building energy and realizing net-zero energy buildings. Based on the developed mathematical model, this paper assesses the solar irradiation resources and BIPV potential of residential buildings in different climate zones of China.

Can a rooftop PV system meet the energy demand of low-rise residential buildings?

It can be concluded that the rooftop PV system can at least meet the net energy demand of low-rise residential buildings. Multi-storey buildings can sometimes achieve net-zero energy consumption through the rooftop PV systems, depending on the local solar irradiation and household demand.

Does solar irradiation contribute to net zero energy residential buildings?

The solar irradiation resources of building façades including the north façade are examined. The photovoltaic contributions to net zero energy residential buildings are assessed in China. Partial shading is considered for modeling the building integrated photovoltaic (BIPV) system.

Can a rooftop PV system power a 4-storey residential building?

In Urumqi, Beijing, and Shanghai, the power generation of a rooftop PV system can supply the net load of a 4-storey residential building, which is at an average level. While the rooftop system can only meet the net demand of a 3-storey residential building in Harbin, Chengdu, and Guangzhou.

Does photovoltaic contribute to net zero energy residential buildings?

The photovoltaic contributions to net zero energy residential buildings are assessed in China. Partial shading is considered for modeling the building integrated photovoltaic (BIPV) system. A research framework for assessing the potential of residential BIPV system is proposed.

Which façade has the best solar irradiation?

From a year-round perspective, an optimal tilt angle obtains the best solar irradiation, followed by south façades, east or west façades, and north façades, which receive 102.8 %, 62.5 %, 57.4 %, and 44.5 % of the GHI in Shanghai, respectively. Fig. 7.
