ABSTRACT:
A highly efficient and economic solar distillation unit comprising a plurality of angled trays in a frame, each tray including a vaned absorber element on the bottom surface. The trays are extruded in plastic and cut to size, as are the absorber elements and frame sidewalls. Frame endwalls are cut from flat extrusions. A transparent glass removable cover completes the basic assembly, but many variations are possible, including means to monitor and control water level within the unit from a storage tank. With the exception of an optional check valve there are no moving parts. There are no metal parts, and the basic unit is glued together from plastic extrusions and flat plates.
