Good thought...but there are some challenges to this. Solar orientation varies with the time of the year. Some crags are fully shaded in December but are fully in the sun in the summer. Some face NE, SSW, etc. Some crags are not flat but curve or are multi-faceted, so the aspect can change. Some solar aspects change on time of day due to projections of rock or hillsides that will shade 'em. Simple solutions might leave one disappointed using that as a culling tool to select crags.
