This paper presents a theoretical analysis of a tilted-wick solar still with an inclined flat plate external reflector on a winter solstice day at 30 degrees N latitude. The daily amount of distillate of a still with an inclined reflector would be about 15% or 27%, greater than that with a vertical reflector when the reflector's length is a half of or the same as the still's length.
