Usage and efficiency analysis of electricity generated by PV power plant in a marina or industrial facility

Abstract

In this study, the analysis of the usage efficiency and the time allocation to cover the initial investment cost of a PV power plant to be installed in an industrial facility having constant electricity consumption monthly and a yacht marina having fluctuating electricity consumption in a year (equal yearly electricity in each in total) within the installation assumption of same conditions of PV plant has been done. The PV power plant data with 680 kWp power and located at the same latitude as the yacht marina in the center of Mediterranean were used. For this purpose, it has been calculated that the PV power plant installed power required for the annual electricity need of the yacht marina will be 1357 kWp. With this power, 2,141,117 kWh of electricity has been produced annually and the yacht marina/industrial facility need has been supplied. In addition, the Net Present Value (NPV) was used to calculate the coverage period for the initial investment cost of the PV plant. In the calculations, it has been determined that the time to cover the initial investment cost is 4.31 years in the yacht marina and 4.37 years in the industrial facility. This result showed that installing PV power plants in marinas would be 1.5% more advantageous than other industrial facilities.
