Savings from Solar PV arrays increase when the energy usage is maximised, however as much has habitual changes can help to utilise more energy, there will always be periods of "export," when you can't match the energy demand to the power generation. Solar PV inverters are designed to allow this excess to flow back into the grid with no benefit to the homeowner.
Immersion controllers monitor exported energy and controlled the immersion heater to utilise the electricity within the home, saving the homeowner money by reducing gas or oil consumption.
