*3.1. Lighting Systems*

Lighting for the parking lot is optimized by the provision of 18 lampposts, which run along two main panels across the entire length of the parking lot. Each lamp's strength is 74 W, which aggregates to a total of 1.3 kW. For the most unfavorable case, December 21st was chosen because it is the shortest day of the year. It was hypothesized as a continuous operation that goes from 4:30 p.m. at 8:00 a.m. The resulting power curve is presented in Figure 3.
