In order for an accurate recognition of the constraints, barriers, and facilities obtainable for the use of energy supplies in any country, it is necessary to calculate the amount of utilization of surviving energy potential and the method of transforming these energies through a scientific and precise manner. Typically used photovoltaic systems limit the employment on curved facades. Throughout this analysis, a photovoltaic system based on plastic, small-scale solar panels were designed, manufactured, and evaluated techno-economically. Due to the importance of effective variables, a temperature sensing system was designed and made for an on-line data reception and connection with the computer code, and data from the meteorological station, and NASA were collected. Taguchi Analysis was used to characterize the “more cost-efficient, better” goal for selecting the top system. Cost-benefit analysis of the systems within the COMFAR package was performed: the internal rate of return on the flat, cylindrical, and hemispherical surfaces was 23.82 and 26.70 and 27.46%, respectively. The net present value is equal to 6.74 and 9.95 and 10.83 million Rials. If the system on the flat surface under the standard conditions has a coefficient of 0.73 and the most power production capacity of about 46.71 W with a yield of seven.09%, the system supported the cylindrical and hemispheric surfaces has a coefficient of 0.88 and 0.84, respectively, with the most power production of 55.18 W and 57.50 W, with a yield of 7.45% and 7.55%, respectively. These Systems have an economic justification for attracting capital.
