“…Along with this growth in the valuable insights into the feasibility of the BIPV system on building skins, however, there is an increasing concern over the feasibility of the BIPV on the untraditional orientations of building skins for BIPV applications. It looks that there seems to have been an assumption in which the northern façades (in the northern hemisphere) are economically unfeasible because the radiation there is low [11][12][13][14][15][16][17][18][19][20][21][22].…”

The business model of building-integrated photovoltaics (BIPV) is developing expeditiously and BIPV will soon be recognised as a building envelope material for the entire building skins, among other alternatives such as brick, wood, stone, metals, etc. This paper investigates the effect of climate on the solar radiation components on building skins and BIPV materials in the northern hemisphere. The selected cities are Stavanger in Norway, Bern in Switzerland, Rome in Italy, and Dubai in the UAE. The study showed that for all the studied climates, the average incident radiation on the entire building skins is slightly more than the average incident radiation on the east or west facades, regardless of the orientations of the building facades. Furthermore, the correlation between solar radiation components and different BIPV technologies is discussed in this paper. It is also found that when it comes to the efficiency of different BIPV cells, the impact of the climate on some of the BIPV technologies (such as DSC and OSC) is much more significant than others (such as c-Si, mc-Si and CIGS). The evidence from this study suggests that in climates with higher diffuse radiation-or with more overcast days per year-the contribution of IR radiation decreases. Therefore, the efficiency of BIPV materials that their spectral responses are dependent on the IR radiation (like Si and CIGS) in such a climate would drop down meaningfully. On the other hand, the DSC and OSC solar cells could be a good option for cloudy climates since they have more stable performance, even in such a climate. Although, their efficiency compared to other BIPV materials such as Si-based BIPV solar cells is still significantly less thus far.

“…The pricing of BIPV modules follows entirely different principles than the pricing of conventional PV modules. These prices even contradict each other [26,27,28]. The price of conventional photovoltaic modules is given in currency unit per Wp, e.g.…”

BIPV modules provide a high degree of design possibilities and additional functionalities in combination with the plain electricity generation well known for standard photovoltaic installations. Consequently, the specialized know-how to understand BIPV, properly design and manufacture them requires much more than the electrical knowledge developed and applied in standard photovoltaic systems. Expertise of building physics and building regulations are also required on a high level. As BIPV modules are usually custom designed, typical electrical design and simulation tools cannot be used without modifications, while deeper insight of complex shading influences and specialized overall system design are advantageous. Authors of this publication were involved in well over 1000 BIPV system designs and developments, and their experiences are shared. Recurring questions, issues and mistakes of various BIPV projects are touched, whereas special emphasis is provided on BIPV engineering procedures, system design complexity, as well as shading issues and differentiation of shading according to their origin.

“…The main relevant results were the reduction of CC potential when they are compared to conventional energy sources, as expected. Regarding te economic pillar, Gholami et al (Gholami et al, 2019) published an article including a holistic review of five case studies around the world. Moreover, two interesting studies about end-of-life (EoL) stage of PV could be highlighted: Goe & Gaustad (Goe and Gaustad, 2016) studied the influence of the recycling process of PV modules in global warming potential (GWP) credits for decreasing impacts in United States (US), while Latunussa et al (Latunussa et al, 2016) published an LCA about an innovative process for recycling these panels, including a complete state-of-the-art on EoL techniques.…”

Building Integrated Photovoltaic (BIPV) systems have been increasingly used as a means to generate electricity on-site, and their diffusion will increase in the near future. The objective of this article is to carry out a sustainability assessment of a BIPV system installed in Turkey regarding the three pillars: environmental, economic and social potential impact, in order to develop different indicators. For the socioeconomic analysis, a Multiregional Input-Output (MRIO) method was used to estimate production of goods and services, value added creation and employment opportunities. For the environmental evaluation, an Environmental Footprint (EF) analysis was performed. The levelized electricity costs and the greenhouse gas emissions abatement costs were also calculated.Results showed that the socioeconomic effects are relevant, although only a 23% of these effects remain in Turkey. The environmental profile is also good in terms of climate change impacts, showing substantial reductions in greenhouse gas emissions compared to fossil fuel alternatives for electricity generation. Regarding the life cycle stages of the technology, the highest environmental impacts are produced in the PV manufacturing processes. The electricity produced is still more costly than fossil-based technologies and in the highest range of PV technologies, but greenhouse gases abatement costs are not so high when compared to other references.
