A solar energy collection system harvests solar energy from large open areas. A length of flexible solar collector is provided for unrolling along a supporting surface. A first layer of the solar collector is an uninsulated base panel for directly contacting the ground or other supporting structure. A plurality of parallel conduits are sealed along the length of the flexible base panel and have a high light absorption and a low infrared emission for containing a flowing liquid to be heated by solar energy from the sun. A length of a covering material is placed parallel to the base panel and between the parallel conduits and the sun and sealed to the base panel for containing a low pressure fluid to reduce heat loss from the flowing liquid and to inflate the structure formed by the ground cover and covering material. Heated fluid from the parallel conduits is collected in a header for delivery to a power generating system. The heated liquid is passed through a boiler for boiling a fluid with a low boiling point, such as a refrigerant, and the vapor can then be used in a conventional power plant for generating output energy. In one embodiment, the power plant condenser is cooled by the evaporation of water sprayed into cooling air adjacent the condenser.
