The potential of solar panels on roofs built above national highways as a source of solar energy was investigated in theInternational Journal of Energy and Environmental Engineering(December 2013). Computer simulation was used to estimate the monthly solar energy (kilowatt-hours) generated from solar panels installed across a 200-kilometer stretch of highway in India. Each month, the simulation was run under each of four conditions: single-layer solar panels, double-layer solar panels 1 meter apart, double-layer solar panels 2 meters apart, and double-layer solar panels 3 meters apart. The data for 12 months are shown in the table. To compare the mean solar energy values generated by the four panel configurations, a randomized block design ANOVA was conducted.
