1. Introduction
Combating climate change through a decarbonized economy is a priority of the Europe 2020 strategy [1]. The importance andpotential of solar photovoltaic energy to achieve this objective is unquestionable. Currently, solar photovoltaic technology, despite its low efficiency (between 10 and 20%, depending on the type of technology [2–4]), can reach grid parity in certain geographic areas [4]. So far, the existing implementation of photovoltaic generators in buildings is accomplished mainly by means of elements added to the roofs of buildings or by the construction of attached photovoltaics (BAPV), which provide a questionable aesthetic solution. Over last decade, building integrated photovoltaics (BIPV) products of various efficiencies have been developed in the solar sector in order to improve urban integration [4]. The evolution of photovoltaic technology allows to establish that depending on the technology and BIPV solutions applied to roofs [5,6] or facades [5,7,8] costs have been reduced as the effi- ciency values have gone up. There are multiple BIPV products that can be implemented in every building and situation: claddings with different azimuth angles [9], facade shading elements (carport, awning, shutter and eaves) [10], windows with semitransparent solar cells [11], skylights and atriums [12,13]. The mentioned solutions have already been implemented in pilot buildings throughout the world, presenting problems of its multiplying effect as a consequence of an inaccurate previous study of the solar resource, its incidence over the different faces and an incorrect placement of PV elements on the building envelope [14–18]. There are various prestigious databases that enable one to predict the solar irradiation received in a specific geographical location, given its coordinates and altitude, as well as the orientation of the plane (azimuth and zenith) and its tracking system (fixed, horizontal, vertical or polar axis) [19,20]. Allowing the analysis of the solar irradiance received by the buildings, several algorithms which are based on the data supplied by local weather stations or on the already mentioned databases, have been developed and published. The provided results allow to optimize the position and orientation of the photovoltaic elements (BAPV and BIPV), to determine the annual efficiency and to obtain the output energy; fundamental factors that define the internal rate of return and the pay back of the photovoltaic investment [21–23]. Marked improvements are introduced when the shading of nearby buildings and obstacles on roof-top photovoltaic systems is calculated [24,25].
