The use of closed-loop on–off control with feedback provided by a solar sensor allowed capturing between 27.7% to 42.7% more energy in different seasons of the year with respect to a fixed PV system. The authors concluded that the closed-loop ST systems are more precise but more complicated and expensive to implement than open-loop ST systems.
The thermostat heater is an example of closed loop control system. The thermostat senses the temperature of the system and maintains the temperature. In a thermostat heater system, the desired temperature set point serves as the input, indicating the temperature the user wants to maintain in the room.
In a closed loop (indirect) system, a heat transfer fluid such as glycol circulates through the collector panels, absorbing heat. It carries this heat to a heat exchanger in the hot water cylinder, where the heat is transferred to the water.
In an open loop (direct) system, water heated in the collector panels goes back to the cylinder and then to taps and appliances for household use. A system such as a temperature controlled pump to allow hot water to be circulated through the panel on cold nights to prevent freezing must be integrated into the circuit.
