The invention is an assembly of elements to collect solar energy and rain water. Solar energy is converted to electricity by either photovoltaic film or laminate panels or sheets mounted atop arcuate, curved canopy structures that are formed and positioned like “wings”. Rainwater is collected by the low-incidence arcuate curved wings and directed to a central trough along the wings' structural spine, which conducts it through a support column to a water container or vessel. In a preferred embodiment the vessel is an underground container extending parallel to and as long as the above-ground structural spine of the assembly.
