  From the very recent importation
records of the REOAL and CSERS, the
average cost of solar water heaters
(good quality flat plate collectors) are
as follows:
    • 200 liters with over 3 m2 is
    about 960 L.D
    • 300 liters with over 4 m2 is
    about 1340 L.D
 The cost of solar water heaters
considered in this study is the average
of the above costs and equal to
 1150 L.D.
