Patent ID: 8001785

Claim:
A solar energy-based water heating and power generating module, comprising: a compound module panel, said compound module panel comprising an outer wall adapted to absorb solar energy, an inner wall opposite to said outer wall, an enclosed chamber defined between said outer wall and said inner wall, and a circulation pipe arranged in said enclosed chamber for making heat exchange with said outer wall, said circulation pipe comprising a cold-water inlet and a hot-water outlet; a water chamber mounted at a top side of said compound module panel in water communication with said cold-water inlet and said hot-water outlet; a power generator house abutting a back side of said water chamber; and at least one power generator mounted in said power generator house, each said power generator comprising a housing, a field magnet set fixedly mounted inside said housing, an oscillator pivotally mounted inside said housing, and a coil mounted on said oscillator, whereby the oscillator is actuatable to oscillate by air expansion and contraction inside the housing due to a temperature difference and to further generate electricity.
