The integrated solar absorption heat pump system includes an absorption heat pump assembly (AHPA) having a generator, a condenser in fluid communication with the generator, an evaporator/absorber in fluid communication with the condenser and the generator, and a heat exchanger in communicating relation with the evaporator/absorber; a solar collector in fluid communication with the generator of the AHPA; a photovoltaic thermal collector in communicating relation with the evaporator/absorber of the AHPA; a plurality of pumps configured for pumping a fluid throughout the system to provide the desired heating or cooling; a power storage source, e.g., a solar battery, in communicating relation with the photovoltaic thermal collector; and a coil unit in communicating relation to the evaporator/absorber for receiving an air-stream. The absorption heat pump assembly can include an absorber and a solution heat exchanger.

The photovoltaic panel cleaning machine is installed upon a linear array of photovoltaic (solar) panels, automatically operating periodically to remove any dust, debris, and/or light condensation from the panels to optimize their efficiency. The machine is driven back and forth along tracks extending along opposite edges of the panel array, and receives electrical power from a storage battery charged by the solar panel array. The machine includes an air compressor, a blower and nozzles that blow dust and debris from the solar panels, and two different roller brushes. Air is blown over the panels on the first pass, and the machine then reverses direction to apply a first roller to the panels for further debris removal on a second pass. A third pass is made using the air blower, and the direction reverses once again, the second roller being applied on the fourth pass to statically attract any remaining debris.
