An assessment of using different passive condenser designs of the solar distiller based on productivity, exergy, energy,  energyeconomic, exergyeconomic, enviroeconomic is investigated experimentally. Five different  condenser designs are considered; (i) glass plate condenser, GC (CSS), (ii) corrugated aluminum sheet heat  sink  condenser,
 CHS, (iii) aluminum heat sink condenser having vertical rectangular fins at
its  outer surfaces, RHS, (iv) aluminum heat sink condenser having pin fins at its outer surface, PHS, and (v)  aluminum heat  sink condenser having pin fins at its outer and inner surfaces, DPHS. The findings show  that augmenting the rate of condensation by varying the condenser design increases the still yield to a  limit and  then decreases this yield at a higher condensation rate. CSS has the smallest freshwater yield  and still with PHS has the maximum production with an increment of 54 % comparing with GC
condenser. The  maximum increase of the daily average energy and exergy efficiencies of the still is about 55.3  % and 73.1 %, respectively in case of PHS condenser compared with CSS. Still with DPHS condenser has  the maximum production cost while the still with PHS or CHS condenser has the minimum. Distiller with  PHS condenser is the best system in achieving CO2 reduction benefits of 1.82 tons CO2/year.
