Solar Radiation and Photovoltaics

In a simple horizontal or inclined basin type solar still, the basin receive solar radiation through the transparent cover, heats the water to evaporate, hot saturated air rises, vapour condenses at the cool lower surface of the glass cover, slides down and is collected using a drain. In a single effect still, the latent heat of condensation is exhausted as waste. In multi effect still, the heat of condensation of the previous effect is utilized in the next effect to heat the water. This article reviews the different methods tried by different researches to improve the productivity of multi effect solar still.
