The Hot water tank is ground based and has a recirc pump on it, I am going to use the controllor that came with the system and temperature probe from the evac tube on this  2 metre cylinder to control the water flow out of the cylinder.

On my calc, my existing evacuated tube is producing equal to about 470 watts per hour, so far in trials on a 80L old hot water service with a 72V element i am producing approx 900 watts with the 2.5kw of panels facing south away from the sun, the PV setup starts heating the water up by 7.30am, and the evac tubes setup starts moving water at about 10.00am
