Are roofs a good source of energy for PV generation?
Accordingly, roofs present the highest efficiency potential for PV generation systems in buildings (Lin et al., 2014). However, the impact of roof equipment (e.g., water tanks, central air conditioning units, ventilation equipment, communication signal base station) and their shadow must also be considered.
Can rooftop solar power replace traditional electricity sources?
Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
What is a building PV generation system?
Building PV generation systems can be applied on roofs (Kumar et al., 2018) and/or facades (Quesada et al., 2012), and the installed PV generation system can share the grid load. There are various types of building loads for different functions, such as cooling, heating, annual electricity demand, air demand, and illumination.
What are the applications of PV roofs?
Public buildings are the main applications of PV roofs. The roof shape greatly influences the design of the PV system. The selection of BIPV or BAPV and of PV cell materials should be based on local characteristics.
What is building-integrated photovoltaic (BIPV)?
A building PV generation system can be divided into building-integrated photovoltaic (BIPV) and building-applied photovoltaic (BAPV) technology. BIPV refers to use the PV panels as the substitute for traditional building materials, through integration into the building envelope, such as in roofs, windows, facades, balconies, and skylights.
Are roofs good for solar energy harvesting?
The unique properties of roofs, such as good sunlight incidence, good ventilation conditions, no redundant shielding, and flexible tilt angle for PV panels, are advantageous for solar energy harvesting. Accordingly, roofs present the highest efficiency potential for PV generation systems in buildings (Lin et al., 2014).
