| Summary: | Renewable energies such as thermal solar energy are accessible energy hydrous for desalination water, recycling and hot water production. Heat is produced by greenhouse effect in the sensor. It is no polluting form of energy according to the sustainable development.In this paper the design of sensor photothermic prototype with polymeric film absorbing, the materials radiation properties, the analysis of different energy losses in the system and the energy balance will be presented. The evolution of incidental solarillumination on the horizontal plan of sensor and the temperature distribution are studied. Results showed that the temperature obtained by thermal conversion depends on the absorbing characteristics of the polymeric film, radiation intensity and time exposure.
