DIY 100 sft innovative  passive solar panel with black pipe

The following chart explains DIY 100 sft solar water heater performance recorded during Jan Feb 2012 in Kathmandu. The maximum temperature attained so far was on 10th Feb with the maximum gain of 73.6 F form the lowest ambient temperature of 37.4 and 
where stored hot water in the tank attained  111 F after normal sunshine hours, from 3 Celsius  lowest ambient and recorded storage water at 43.89C at insulated tank of 200 
litres, a net gain of 40.89 degree Celsius


Usually this part of the year 
ambient lowest water temperature stays slightly above ambient air temperature in the morning by 2-3 C.
The ambient air temperatures derived from Nepal Government Metrological forecasting Division http://www.mfd.gov.np/index.php

We have been taking readings continuously and updating it too, The highest recording till date obtained yesterday, that is on 22nd March 2012 is 139 F, which is almost 60C. Which has enticed us to find other venues for its application too, may be towards absorption AC....!!!! ????
