## 2 Materials and Methods
### PV System Design
#### 2.3.2 Electrical Design  
The geolocation specifications, electrical components, and designed tilt angle are depicted in Table 2.  
The PV system was designed for each zone, taking into consideration length, shading, and mutual shading along the route. PVSYST was used to simulate the PV system and determine system capacity in each zone. The designed PV system comprises elevated PV modules along the path of the route with a tilt angle of 10\({}^{\circ}\) and an azimuth angle that corresponds to the route path. The azimuth angle of different PV sections is not optimum; however, it matches the route direction to take the overall scenery into consideration and to generate shading over the routes and pedestrian paths. Table 3 summarizes the resulting PV system design for each zone, where \(P_{nom}\) is the nominal power for PV system in the specific zone (in kw peak).  
As can be seen from Table 3, if the whole route is covered by PV systems, the generation greatly exceeds the system energy requirements. Some of the zones' yields are less than others due to shading, or direction, leading to zone-specific payback periods. Therefore, which zone to use must be carefully evaluated.
