Information’s are given about that a solar energy power plant was developed and experiences of operating photovoltaic PV-panels in the University of Debrecen, Department of Agricultural Machinery. The electricity performance of the incorporated PV-panels (Kyocera, Dunasolar, and Siemens) are 8, 64 kW. There are 3 reasons operating the PV-panels and inverters:1. In the field of education: introduced the solar panels and PV-panels and inverters.2. In the field of research work: measuring and calculating the coefficient of efficiency, exposure metering, economical calculations. 3. For exhibition: demonstration and propagation the renewed energy.
