What are the energy-related features of building-integrated photovoltaic (BIPV) modules?

This paper reviews the main energy-related features of building-integrated photovoltaic (BIPV) modules and systems, to serve as a reference for researchers, architects, BIPV manufacturers, and BIPV designers. The energy-related behavior of BIPV modules includes thermal, solar, optical and electrical aspects.

What is building integrated photovoltaics (BIPV)?

1. Introduction Building-Integrated Photovoltaics (BIPV) is an efficient means of producing renewable energy on-site while simultaneously meeting architectural requirements and providing one or multiple functions of the building envelope , .

What are the performance-related requirements for BIPV modules and systems?

The performance-related requirements for BIPV modules and systems have an impact on the energy consumption of the building and include BIPV electrical performance, thermal insulation level, solar heat gain coefficient and optical properties. Fig. 1. Examples of BIPV systems.

What are electrical design guidelines for BIPV systems?

Electrical design guidelines for BIPV systems could be similar to those of standard PV systems. However, the different boundary conditions set by the architectural integration can cause general design schemes and component selection criteria to change. BIPV systems can be stand-alone or grid-connected.

Are IEC PV standards applicable to BIPV systems?

In all cases, IEC PV standards related to performance and safety of PV systems are applicable to BIPV systems. One of the main constraints when designing a BIPV system is the non-homogeneity of solar irradiance over the totality of modules, and the more frequent partial shading than for conventional ground-mounted PV systems .

Can a photovoltaic shading system be used in a building?

However, available solutions are still limited compared to products using PV-façade cladding or semitransparent BIPV windows and PV-roof systems (Frontini et al., 2017). Figure 8.8. Fixed large photovoltaic shading systems are widely used in buildings.
