Any structure has a roof that can be made to work with a solar
Photovoltaic system. South is always best but east and west work fine.
It is just the north face we do not use without adjusting the angle to the
sun. Since Colorado is in the northern hemisphere and not at the equator, the
sun never tracks from due east straight overhead to set in the true west.
The sun tracts a southerly arc during every season, more southerly in the
winter than the summer, but still southerly. Therefore we never install a
PV system facing north. In Colorado the best direction to face solar
panels is always going to be south. However that does not mean that
East and West are not suitable, quite the contrary. East is the second best
orientation as it gets very direct sun light from sun-up until early
afternoon and West gets direct sun light from midday till sundown. The
only reason east is belter than west is that in the afternoon we often get
thunderstorm producing cloud cover that partially blocks some of the
sun’s rays from reaching the PV panel.
