Abstract
A solar photovoltaic water heating system is disclosed having a photovoltaic solar panel array, a storage tank containing water to be heated, a resistance heating element in the water to be heated. The water heating system matches the load resistance of the resistance heating element to the power that is available from the photovoltaic solar panel array in order to maximum energy transferred to the water in the storage tank.
Claims5
A solar photovoltaic water heating system comprising:
- a. a solar photovoltaic panel for producing direct current power;
- b. a water storage tank including:
- i. a cold water inlet;
- ii. a hot-water outlet;
- and
- iii. a variable resistance heating element having an electrical resistance;
- and
- c. a control system connected between the solar photovoltaic panel and the variable resistance heating element and configured to vary the resistance of the variable resistance heating element to match the direct current power supplied by the solar photovoltaic panel.
