Solar wasted watts/volts
I am curious what happens to the watts /volts when your system is fully charged and you have no demand? Were does the extra power go?

Ok forget the hot water part If i put a over size system in how does the system dissipate the extra power being generated?
It is not being generated. Like you only get water if you turn on the tap.
Aside, there is a discussion of "over-panelling" for your controller's rating (with MPPT only--don't do it with PWM) on ISTR Morningstar's website. In the shoulder hours you get more amps with the extra panelling and those amps are still less than controller rating. Your controller cuts off the amps at its limit so you lose some mid-day AH, but you gain over the whole day averaged out for your AH haul.
So some over-panelling with MPPT is good, but within reason of course.
Next you will ask what happens with the extra amps the controller cuts off at its limit and can't use? :)
