Suitable location based on 15o slope angle
The suitable locations for solar PV based on 15o slope angle are highlighted as polygons in figure 7. The results show less suitable locations using the threshold value of 15o slope highlight because the threshold value is only suitable for a nearly have flat area.
Figure 7. Suitable solar PV location based on 15o slope angle The suitability of the location can also be assessed by calculating the number of solar PV panel that can fit in each polygon. A panel requires one and half meters area. 15% buffer was added to the area for the mounting frame and additional spacing. The number of solar panel that can fit is based on the formula: Polygon_Area/Solar panel size. Based on the findings, the maximum area for a solar panel is 2.6m2. Thus, if the entire rooftop polygon area that exceeds the 2.6m2, will be included as suitable location for the solar PV.
