A method comprises generating power at a solar photovoltaic cell; receiving, at a controller, one or more input parameters pertaining to a power output of the solar photovoltaic cell; introducing liquid to the solar photovoltaic cell in response to the power output of the solar photovoltaic cell to increase the efficiency of the solar photovoltaic cell; recovering heat from the liquid introduced to the solar photovoltaic cell; and selecting an appropriate distribution of the power output of the solar photovoltaic cell to one or more power-drawing components in a way that maximizes a chosen objective for the whole of system.
