Evaluation of "subside elimination policies" economical effects on applying photovoltaic systems for commercial buildings in Iran

PV system establishment needs full investment which must be economical versus network energy cost. This analysis is one of the most important parts of a solar system design. In Tehran the shape of the load curve of a commercial buildings and the form of the sun radiation curve are alike. By considering this coincidence there could be a way to use solar power to supply a part of the demand. According to strategic plan of the administration, the energy subsides must be eliminated and energy prices will be increased to the actual price in 5 years. In this study a grid connected PV system will be analyzed in different increasing scenarios to indicate when a PV system should be considered for application in grid connected commercial buildings. Tehran solar data and energy prices will be used for this analysis.
