OK, I'll give you clue as it is unlikely you would ever work it out
and yet again you demonstrate your inability to read. The rest of
the heating system was very efficient. As it was efficient the cost
of heating water was low and the saving from the solar water heating
was therefore also low. The amount of energy available for the
solar panels to collect is unalterable. If they had been 100%
effective they would still have been a poor investment.
