“…Optimizing the tilt angle, panel facing, and distance between PV panel rows are suggested by Jouri, and Henrik, [7], for Lund and Miami cities, using a simulation program, they concluded that the maximum annual output can be achieved by choosing 0 ‫﮿‬ inclination without spaces between rows. Similar aspects studied by Weissenbacher, [8], and Castellano, et al, [9] In Baghdad city, where large number of sunny days during year, calculation of solar energy from collector panel array is very important to obtain the optimum array output. The aims of present work are:…”

Increasing use of solar energy as a clean and free solution for energy demand necessitates proper use of its equipment, enhanced spatial planning and distribution of solar collectors, optimum directional facing and tilt angle to ensure maximum solar radiation falling, and decreasing as possible as the shading effects of panel arrays. Most existing references lack comprehensive data about shading effects that varied along the year and design of solar array. In the present work, enhanced theoretical design data of solar collector arrays were tabulated for each month in Baghdad. MATLAB program was used to calculate the maximum clear sky solar radiation per unit area per day. The tabulated data yields an economically saved design of solar field or rooftop collector systems. The results indicated that, the shading effect on panel arrays almost vanishes when the distance between two panel rows to panel height ratio is greater than 1 in summer and greater than 2 in winter.

“…However, some buildings can also shade their own envelope. If the building envelope shades the PV module, the shading must not exceed 10% of the total area of the PV module at any time between 10 a.m. and 2 p.m., when solar radiation is highest [66]. Such a repetitive modeling process from architectural design results in lost time, additional work, and possibly some loss of information (i.e., geometric and component inconsistencies due to incomplete understanding of the model).…”

Building integrated photovoltaics. Overview of barriers and opportunities

Based on the available literature, the status and prospects for further development of the building integrated photovoltaics (BIPV) market were analyzed. The results of the analysis show that the high investment costs and the lack of information about installed BIPV systems and BIPV technology are a problem for the stakeholders. BIPV technology is an interdisciplinary problem, so the cooperation of a large number of different experts is important. However, it is not yet at a satisfactory level. Another problem is the overlapping of responsibilities of HVAC installers, interior designers and facade manufacturers. On the other hand, the incentives of the EU regulatory framework and beyond to use renewable energy sources in both new buildings and renovation of old buildings, as well as the desire for energy independence, encourage the application of BIPV technology. An analysis of the electricity production potential of BIPV integrated into the walls and roof of the building was made for four geographical locations. A comparison of the production of electricity on the walls and on the roof of the building was carried out. The analysis shows that on the 4 walls of the building, where each wall has the same area as the roof of the building, approximately 2.5 times more electricity than on the roof can be generated. In the absence of available surface for installing a PV power plant on the roof, the walls represent a great potential for BIPV technology.

“…Raptis et al [52] found an optimum tilt angle of 30° S in Athens. Lastly, the work by Weissenbacher [53] must be mentioned here as it gave a new definition for the optimal tilt angle of solar flat-plate convectors for energy policy makers.…”

The optimal solar radiation received on an inclined surface is always critical for energy purposes at a location or in an area. Therefore, many attempts have been made worldwide to calculate the optimum tilt angle for this purpose. The present study gives an answer about the south-oriented inclination or inclinations of solar panels in Greece for maximum efficiency. The analysis shows that an angle of 25° (and 30° in some cases) facing south is the most appropriate. To calculate this, the energy sums received on surfaces with inclination angles of 0–60° with a step of 5°, including φ° (φ being the geographical latitude) facing south at 33 locations in Greece were analyzed monthly, seasonally, and annually. The solar radiation data used in this work comes from corresponding typical meteorological years (TMYs) generated for the above locations. TMYs are used for the first time worldwide for the study of the optimum energy received by solar panels tilted south. Four new energy zones are defined to cover the whole of Greece.
