Wei et al. [8] also analyzed the slope’s effect for receiving insolation based on monthly average solar radiation data and the feasibility of building SUPP in west areas of China. A simplified mathematical model was prepared and solved using MATLAB. The model was used to predict the best gradient of the sloped solar collector which was founded to be around the latitude value where the plant was located with a floating rate varied within 20%.
Cao et al. [9] designed a SSUPP provide electric power for remote villages in Northwest China, and Lanzhou City was taken as an example. The designed plant, in which the height and radius of the chimney are 252.2 m and 14
