Abstract
Floating solar PV power plants are currently emerging form of photovoltaic technologies that uses the surface of water bodies such as irrigation, canals, water reservoirs, lakes and failing ponds, ocean, water treatment plants, etc. Uses of man-made reservoirs for floating solar PV have significant advantages over land-based and other water body’s installation. Ethiopian power authority planned to install 125 MWp grid connected battery-less land-based PV solar systems at Metema in Amhara region. In this paper, output performance of the solar PV plant at Metema and on Lake Tana is compared. Factors that affect the PV power plant efficiency such as wind speed and temperature are modelled and simulated in MATLAB/ SIMULINK. Panels and inverters are selected and the system components are configured to generate 125 MW. The system is modeled by MATLAB/SIMULINK to show the efficiency variations of solar PV. Due to high temperature and wind speed, solar PV efficiency drops. The efficiency of solar PV on water surface is improved by 2.88%, 3.6 MW from 125 MW plant, over the land surface. This indicates that temperature and wind speed are the major factors that affects the output performance of solar PV generation systems.
