Study of analytical observations on energy matrix for solar stills

• The performances based on energy matrix have been intensively observed. • The selected systems are compared for EPF, EPT, LCCE, and yield. • System-2 reflects greater yield with higher energy of embody. • System 8 observed better with least time for energy pay time (EPT). The extraordinary amount of solar irradiative energy all around the Earth has one of the motivational factors to work with such systems that utilize these for the services...
