      of Low Cost Solar Water Heating System for Domestic Purpose | 
| Solar flat plate collectors are employed to heat water with solar radiation.
      Considerable savings in energy can be achieved where there is a requirement
      for hot water for a household to put up a system to heat 100 litres of water
      per day at 500C - 600C. This high cost has prevented large scale acceptance
      of solar hot water systems. |
