Abstract

The use of renewable energy, especially solar photovoltaic power, is essential for energy efficiency and reduces emissions that harm the environment and human health. In this study, a 150 MW on-grid photovoltaic system was designed and analysed by PV-sys software. The work's location near the river makes the site less hot. The technique of the modules is bifacial, which has high efficiency and a lower annual degradation rate of about 1%. The optimum tilt angle, spacing between modules and height of modules over the ground are 30 o, 6m, and 1.5m, respectively. The area of the rooftop and ceiling of the garage is sufficient to install the system. The annual irradiance incident, output power and PR are 2033.9 kWh/m2, 268.169 MWh, and 85.89% respectively. The total emission of CO2 is 5697.1 t. The cost of the system is 150,000,000 $, and the payback period is 6.6 years. The realized profits exceed 200% of the cost price in just twenty years. Installing the current system, providing heat insulation for the building's rooftop and garage ceiling. Also, free energy without gas emission, and new jobs. Compared to a hybrid system of the same capacity.
