Building-Integrated Photovoltaics

Photovoltaic (PV) technology has shown a turbulent trajectory in research, development, and deployment, which has led to an expected 0.5 terawatt-peak-installed capacity globally at the end of 2018 (IEA PVPS 2019). Today, prices have more or less stabilized, and market volumes show a healthy growth while national support schemes are being reduced or redefined, which all exemplify that PV is well on its way to becoming a major player in the supply of renewable energy in the coming decades (Breyer et al. 2017). Most of the installed capacity in the built environment can be found on roofs of buildings in residential and commercial districts. In residential areas, PV is usually attached or added to the roof, and therefore one generally refers to this as building-attached PV (BAPV). Integration of PV in the building envelope (roof and/or façade) is then referred to as building-integrated photovoltaics (BIPV). This chapter provides many examples of BIPV; in Figure 5.1 the difference between BIPV and BAPV is illustrated for a roof.

Photovoltaic (PV) system consists of a series of components: PV panels to absorb and convert sunlight into electricity by semiconductor materials; an inverter to convert the electricity from Direct Current (DC) to Alternating Current (AC) before the electricity is fed into the utility grid; mounting, wiring, and other accessories. If the generated electricity cannot be connected to the grid, battery storage solution can be integrated into the system. PV panels are modular and composed of multiple solar cells. An array of PV panels forms a PV system. There have been various configurations of PV systems available, within which rooftop mounted and building-integrated systems are most commonly adopted in building projects. Building-integrated photovoltaic (BIPV) are PV panels formed directly as building materials to be used as part of building envelope. They can be used to replace conventional building materials, such as roofing, skylight, window glazing, curtain wall, shading device, and façade cladding. There have been numerous types of BIPV products that can be adopted on a building envelope, which increases the sunlight collection area and covers a larger proportion of building energy use. Part of the cost of BIPV system can be offset since the cost of conventional building components has been saved.

The traditional way of installing PV panels on buildings is mounting PV modules to a separate metal support structure on the roof, which is known as building-adopted photovoltaic (BAPV). In contrast to the BAPV approach, building-integrated photovoltaic (BIPV) is defined as an architecturally integrated building element: The electricity-producing modules are both a functional unit of the building and also part of the exterior building envelope, as these modules replace conventional building materials (Prasad and Snow 2005). The fields of BIPV application are the roof areas of the building, as well as building facades, such as vertical walls, skylights, windows, and external shading devices, depending on the particular features of the PV materials.

The share of renewable energy has increased in the world primary consumptions from 14% of global demands in 1998 to 19.3% in 2015 (Goldemberg, 2000; Renewable Energy Policy Network for the twenty-first Century [REN21], 2017). It is expected that renewable energy share takes one quarter of the whole energy market by 2040 with an average annual increase rate of 2.8% (Energy Information Administration [EIA], 2017) and a potential to be expanded over a long-term period of time (up to 30–80% by 2100 according to Panwar, Kaushik, and Kothari (2011)). Among the markets of clean energy, photovoltaic (PV) technologies have shown a promising success during past years while it was predicted to keep permeating with further improvements in PV’s performances (REN21, 2017). Solar PVs are vastly integrated or partially integrated to building roofs and façades, known as building integrated photovoltaics (BIPV), converting solar energy into electricity on the site and supporting the building energy demands (Elkarmi & Abu-Shikhah, 2012; Bramanti, 2015).

The term BIPV (Building Integrated Photovoltaic) is normally used to define buildings incorporated with PV circuits on the roof or envelope system. IBIPV systems can be used to replace roofing, curtain walls, glazing, or special elements such as eaves or canopies. It is usually applied in the concept of green architecture as an energy-saving strategy through the utilization of solar radiation, which is an environmentally friendly renewable energy source (Howells and Roehrl 2012). Meanwhile, Building Integrated Wind Turbine (BIWT) is a building designed using wind turbines in the facades to produce energy (Arteaga-López, Ángeles-Camacho, and Bañuelos-Ruedas 2019).

Building-integrated photovoltaics (BIPV) are solar PV materials that replace conventional building materials in parts of the building envelopes, such as the rooftops or walls. Furthermore, BIPV are considered as a functional part of the building structure, or they are integrated into the building’s design (Peng, Huang, and Wu 2011).
