Optimal Design of a Solar Desalination Unit with Heliostats

Figure 9

Different densities of incident heat flux to the cell: sum of the densities of reflected heat flux by the three heliostats (), density of the heat flux of solar rays (-), density of reflected heat flux by heliostat #2 (-·), density of reflected heat flux by heliostat #1 (···), and density of reflected heat flux by heliostat #3 (- -).
