In recent decades, growing energy demand worldwide has significantly fueled energy production, leading to environmental impacts such as global warming and ozone depletion. it has also endangered the species. Hence, the whole world has started shifting towards green energy generation, eliminating all the negative impacts on the environment. Solar energy is the most CO2 emission save compared to non-renewable energy sources. A photovoltaic generator is useful in areas well exposed to the sun. This paper is aimed at the total amount of energy generated by the solar system connected to the grid on the 230 kV transmission line. This result was conducted by comparing the energy generated with the tilt angle of 15°,20°,25°,30°and 35°. The most energy generated is produced with a 25° of tilt angle according to the simulation result in this paper. The result was simulated by using PVsyst. This paper presents the energy production of a 40-MW grid-connected photovoltaic system located at Minbu Township in Myanmar. The simulation is carried out in order to get maximum energy production and the incident radiation, performance ratio, energy into the grid, and energy output at array and losses. Based on the simulation result, it is concluded that the maximum energy production and performance ratios are 75730 MWh and 81% through the year. The CO2 emission was saved 424781.5 tons per year. The incident energy in the collector plane is 5.220kWh/m 2 /day. This research is only conducted for analysis of existing grid-connected utility-scale solar PV systems and not provided for advanced techniques.

Photovoltaic and thermal systems are the two topologies that use solar energy to produce electricity. The term "photovoltaic" derives from the sun's light (photo), which creates a DC voltage (voltaic). By exposing PV cells to solar irradiance, which causes the electrons to flow and create an electric current, electrical power is produced [1]. The usage of solar photovoltaic energy in electrical energy sources is growing as a result of its advantages, which include being environmentally friendly, having low maintenance requirements, and providing an abundance of free energy [2]. In previous research, design, and simulation of grid-connected solar PV systems have been done through PVsyst by considering solar photovoltaic systems at different sites location around the world. It presented design modelling and simulation as well as the technical and economic potential of a solar PV grid-connected electricity generation plant and to reduce the energy consumption of 100MW of electricity at Umm Al-Qura University [3] It also demonstrates the energy production potential of a small-scale grid-connected photovoltaic architecture situated in the Magallanes region of Chile and uses photovoltaic energy in Patagonia [4]. It is compared for different tilt angles to validate the effectiveness of the proposed framework and it is found that the best optimal tilt angle is 25 degrees [5]. The previous research also designed and simulated a “60kWp solar
