Claim 13:
14. The controller of claim 13, wherein the instructions, when executed by the one or more processors, further cause the controller to:
in response to determining that the current water temperature is less than a second PV heat point lower than the normal lower threshold heat point at a third time, determine whether the required amount of the energy is less than or equal to a new updated amount of the available PV energy at the third time in the PV system; and
in response to the required amount of the energy being less than or equal to the new updated amount of the available PV energy at the third time, set the switch to transfer the PV energy from the PV system to the heating device.
