NOVELTY - The system (100) has an inflatable solar collector (120a) connected to a housing (110a), where the housing comprises a electrical air blower to draw air through an air-intake register and direct the drawn air into a air supply tube connected to the collector. The collector includes two chambers separated by a flexible permeable membrane, where air pressure generated by the air blower causes the drawn air to flow into one of the chambers through the tube, to percolate through the permeable membrane into the other chamber and to exhaust from the latter chamber through an air-exhaust register.    USE - Solar-heating system e.g. low-temperature solar-heating system for heating swimming pools and for space heating, medium-temperature solar-heating system for generating hot water for residential and commercial use and high-temperature solar-heating system for concentrating sunlight for generating electricity.    ADVANTAGE - The inflatable solar collector can be manufactured using inexpensive, durable and readily available materials. The collector is inherently resilient to impact and shock, easy to deploy and remove and convenient to clean. The collector occupies less space, efficiently serves as air filters, and can be conveniently stored in a storage compartment of the housing that houses the air blower and easy-to-operate temperature-control circuitry. The collector can be easily adjusted according to the surrounding terrain and secured at a desired tilt angle. The smooth exterior shell of the collector easily sheds precipitation. The air flowing through the collector is effectively heated when the air percolates through the membrane exposed to solar light, and the heated air is returned back to the interior of the house, thus ensuring efficient space heating. The air-release port injects a small jet of air into the corresponding semi-cylindrical sub-chamber to increase airflow near the back end of array, thus decreasing variations in heat exchange rates across the length of membrane, and hence improving overall heat-transfer efficiency.    DETAILED DESCRIPTION - The permeable membrane comprises multiple layers selected from a group consisting of woven fabric, sheet of porous permeable polymer, sheet of pin-perforated material, permeable non-woven fabric and sheet of permeable composite material.
