I've had one for 5 years now and it saves so much money. Feed in tarrifs suck, so just store everything excess in your hot water heater.

The water heater's normal thermostat is still operational. If the max temperature is reached, it just open circuits and then the solar energy goes to the grid again.

    was more mentioning this so others know since you've been running it for ~5 yrs.

    used to sell solar radiant heaters for pools and whatnot, and it was crucial that people know they needed to dump the solar when the water hit temp to avoid all the toys breaking.
