Answer:
Solar thermal energy system
Step-by-step explanation:
In a solar thermal energy system, solar energy is collected through a solar thermal collector which are very different from the solar panels. In a solar panel only solar electricity is produced but in a solar thermal collector , solar energy is entrapped to produce sufficient heat which could heat up the water.The solar thermal collectors are basically made up of copper pipes which are connected to a heat absorbing box which is pace in a thermal insulated bigger box covered by glass.
