Not very portable but far less complex.

Though proven and practical, hydro storage of excess power would require massive towers to be effective, or leverage an existing high reservoir.
Though the idea is still embryonic, thermo-chemical storage would need nothing more than storage tanks and reaction chambers. Also, the arid geographies where sunlight concentrators would be most effective usually lack large amounts of usable water.
