Modeling and Economic Analysis of Greenhouse Top Solar Power Plant with Pvsyst Software

Due to increasing wars and global warming, the issue of providing the supply-demand balance in energy and food is becoming more important daily. When the issue of providing the electricity needed in modern greenhouses and consuming the energy where it is produced are evaluated together, rooftop applications in greenhouses become important. In this study, a photovoltaic system on a greenhouse in an area of 5031.6 m2 was modeled three-dimensionally using PVsyst software in north-south, and east-west orientations at 10°, 20° and 35° angles, and 6 different simulation studies were performed. By determining the cost of the greenhouse and above-greenhouse photovoltaic system to be constituted, an economic analysis study was performed at the point of OG single-term and OG double-term tariffs in the Energy Market Regulatory Authority (EPDK) tariff tables. As a result, the highest electricity production of the power plant was eventuated as 1579.2 MWh at 10° east-west orientation. In the case of the sale of electricity produced in the photovoltaic system installed above the greenhouse, it has been calculated that the OG single-term tariff brings 2 162 443.087 TL, and the OG double-term tariff 2 203 707.83 TL annual income. The lowest electricity generation was at 35° north-south orientation and was 1392.3 MWh. Based on this production value, it has been calculated that in the case of electricity sales, the OG monomial tariff brings an annual income of 1 894 757.401 TL, and the OG binomial tariff brings 1 930 914.04 TL.
