He impact of solar concentration on energy generation. In other words, the boost in electric energy generation is higher than the raise in thermal losses, resulting within a good power balance. 2. Methodology 2.1. Chalcone site Geometric Design and style of reflective Surfaces for PV Panels two.1.1. Style Considerations A flexible PV panel is regarded as to perform the geometrical design in the system. Its dimensions are described in Table two.Table 2.

With regards to the orientation, it can be facing the south axis, then the optimal slope corresponds towards the solar midday sun Roniciclib Protocol Position (Figure 2), so that the solar radiation reaches perpendicularly towards the PV panel. In order to improve the solar radiation that impinges into the PV panel, two reflective surfaces (RS) are added to it. Then av , ah , along with the angles between RS and PV (,) panel are determined by sun-trace performed in GeoGebra software program.Figure 1. Positions for the PV panel facing to the South axis, plus the fixed reflective surfaces. (a) vertical position. (b) horizontal position.Energies 2021, 14,5 ofFigure two. Optimal slope of PV panels for every single monthly characteristic j-day. Place: Lodz, Poland (Latitude: 51.75 ; Longitude: 19.45 , a.a.s.l.: 278 m). Optimal angles were determined by using Geosol open access software [33]. A-L corresponds towards the different configuration of PV panels for each single month.2.1.two. Geometric Style A single sun-tracing was performed for the RS design and style. The configuration for all RS is fixed in relation towards the PV panel, plus the slope of it varies for each and every month-to-month characteristic Julian day. The sizing and configuration with the RS were performed making use of GeoGebra application (69 Altenbergerstra street, Linz, Austria) as might be observed in Figure 3, at 10 June. For this study, each of the reflected sunrays impinge the entire PV panel extension. Then, it really is getting each reflected and global radiation. The dimensions with the reflective surfaces and their relative angles from the PV panel are shown in Table three. These RS dimensions and relative configuration stay invariable in the course of the entire year.Figure 3. Geometric design performed by GeoGebra software program for ten June midday. Both parallel sunrays mark the limit of solar incidence at extreme borders of reflective surfaces (points K and I). For that reason, the direct acceptance and complete reflection zones are identified. (a) vertical position. (b) horizontal position.Energies 2021, 14,six ofTable 3. GeoGebra benefits.

For this midday solar position, Figure 3 shows the different acceptance zones for all sunrays that attain the technique parallel to the major sunray, which can be taken as reference. It truly is firstly identified the direct acceptance range, where t.
