But, the main drawback is the Go-Home after sunset mode.. It needs juice!
BEAM robotics is designed to be extremely efficient. At sunrise, the BEAM circuit would automatically position it back before there is much energy to extract. You could also add a circuit to switch in a battery only when it gets very dark.
