Considering development of industry in the world society and the ever-increasing trend of environmental pollutions, research in the area of method of development and industrialization of clean and renewable energies enjoys special significance. Accordingly, we deal with experimental model analytic study of a new generation of solar water heaters which were manufactured in Islamic Azad University (IAU) – Central Tehran Branch and its experimental model was analysed using K-Omega turbulence model in Ansys Software. Analytic results show limits of 140 to 236 for the average Nusselt dimensionless number. The Nusselt number limits show that temperature changes don’t necessarily have a fixed amount per increase for one unit in thermal flux. The internal and external surfaces of the solar can have an average difference of 20 degrees Celsius during its function. Since the amount of sunlight can’t be adjusted, therefore, the amount of conductive heat transfer and displacement can be increased by controlling temperature and the velocity of the input fluid. Voltage generation increased from 80% to 91% and amperage generation from 71% to 84% in this study. Meanwhile, results show that if the relative pressure entered on the solar panel by the fluid isn’t controlled, it can lead to the breaking of the solar panel from the lower side.
