Technical, environmental and economic analysis of supplying the energy for Tehran Municipality Innovation Center via photovoltaic system

Increasing consumption of fossil fuels due to increasing population and consequent air pollution has drawn attention toward clean renewable energy alternatives. Among renewables, solar energy is potentially considered as the main clean energy source for buildings. In Iran climate with abundant available solar energy throughout the year, harnessing this source could potentially reduce significant levels of fossil fuels and their resultant air pollution in advance. The electricity cost could also be lowered in this approach. In this paper, technical, economical, and environmental aspects of installing photovoltaic system in Tehran municipality innovation centre and technology park are investigated. The modelling is conducted via PVsyst software. A 10 kW photovoltaic system is acquired to have the most efficient capacity regarding the available space and economic viability. The acquired performance ratio and annual electricity generation of the proposed system are 0.861 and 19.3 MWh, respectively. By installing this system, an annual value of 14.8 Ton of CO2 is prevented from emission. Finally, the economic analysis showed that by assuming guaranteed electricity selling price of 1040 Toman/kWh as well as income tax of 30%, the power plant returns its capital investment in 4 operational years.
