Energy supply in a green school via a photovoltaic-thermal power system

In this study, technical, economic and environmental feasibility study of applying an integrated system including grid-connected photovoltaic panels and a forced circulation solar water heater for supplying the required electricity and hot water for a school has been carried out considering international prices of electricity and natural gas by using software. This study explored the potential waste heat recuperation of PV systems for application in green school during heating seasons. In order to make the hybrid system applicable in both heating and cooling seasons, the design details to avoid the overheating need to be scrutinized and the economic impact during the cooling seasons should be examined further. The present study have shown that a school׳s entire energy needs with renewable energy sources in Kahramanmaras climatic conditions can be solved by being able to meet the optimal planning. There is a need to support energy resources, especially when there is no sun in green house application. Green school practice does not only care about the environment but also the economic. Solar energy levels in countries such as Turkey, with good green structures can be improved. Finally, the present study showed that the full energy requirements of green school were supplied.
