What would happen if water supply is irregular ?
A regular cold water supply, at a height of around 2.5 m is necessary for functioning of the solar system. In case cold water is not available continuously, a separate cold water tank may have to be installed , at least equal in capacity to the capacity of the solar system. In case cold water supply is interrupted during the day, the heating of water by the solar system may not be affected significantly, although hot water cannot be drawn for use till the water supply is restored.

What would happen on cloudy days? The heating of water by the solar system will obviously be affected. If it is so cloudy that energy received from the sun is almost zero, the output of solar collectors also will be nil. On partially cloudy days some output can be expected. But, the system can be designed with a suitable electrical back up heater to take care of hot water demand on cloudy days. 16. How much electricity and money can be saved?
