Simulation and tech-economics feasibility of power generation using building integrated with photovoltaic systems

Solar energy is one of the sustainable and inexpensive energy sources in the world. One of the most important uses of solar energy is generated electricity by using photovoltaic systems. Integrating photovoltaic systems with buildings is one of the favorite plans for engineers and architects. In this study, simulation of electricity generation from three different plans of photovoltaic systems integrated with the building and a photovoltaic installation system on the roof in a residential complex was investigated. The panels used in the simulations are monocrystalline, cadmium telluride and thin film. Due to the different characteristics of the panels, different amounts of electricity is produced by them. The simulation results showed that the plan including monocrystalline solar panel has the highest electricity injection rate (871.2 MWh / year) into the grid. The integrated system including thin-film modules has the lowest amounts of electricity generation into the network and also the lowest performance factor. Economic calculations showed that using a combination of integrated system and installation on the top roof, it could be possible to return the investment in 3.65 years. The inflation rate and the purchase price of electricity produced at the power plant play an important role in investing in this area.
