Experimental investigation of solar/wind hybrid system for irrigation in Konya, Turkey

Abstract

In this study, an experimental research for agricultural irrigation was completed for a renewable hybrid power generation system consisting of photovoltaic panels and wind turbine which can be considered as an alternative to Diesel generators used for pumping applications. Generated electricity was used to power a 300 W DC-driven submersible pump at 2.5 m depth of the ground level. Overall efficiencies of the wind turbine and cell efficiencies of the photovoltaic panels in July 2011 were calculated as 33.3% and 10.07%, respectively. It was observed that the daily mean of produced electricity by the system in July was enough to pump daily average 44.1 m 3 /day of water from the depth of 2.5 m and totally 1368 m 3 of water during the month. It was calculated that the amount of pumped water is sufficient to meet water need of the agricultural products that were 12.4 decares of sugar beet, 13.0 decares of potatoes, 13.4 decares for corn, 13.6 decares green bean and 10.8 decares for sun flower with the drip irrigation method. It was demonstrated that the renewable hybrid energy system enables to save the 10410 USD on energy in twenty-year period after the basic payback period of 5.7 years. In addition, the net present value and internal rate of return of the project were found to be 7361 USD and 12.6%, respectively.

Assessing Crop Water Requirements and a Case for Renewable-Energy-Powered Pumping System for Wheat, Cotton, and Sorghum Crops in Sudan

“…Higher energy demands warrant the use of hybrid energy, which can be beneficial in agricultural applications, helping to reduce energy poverty and improve yields, and consequently helping to reduce poverty and improve food security. Some studies have developed renewable energy systems for irrigation purposes, although these studies did not adopt the detailed approach of determining the energy demands according to the crop water requirements [34,35]. A systematic approach to determining the energy demands of crops has been presented herein.…”

MPPT for Hybrid Wind, Solar and Thermoelectric Power Generation Systems for Off-Grid Applications

“…Each panel contains many cells connected in series and parallel to reach the designed voltage level, either 12 or 24 V [12]. Cells convert solar energy into electrical energy as described by Equation (1) [13]:…”

Techno-Economic Feasibility of Different Photovoltaic Technologies

“…By 2021, Turkey ranks 7 th in Europe in terms of installed power, although it started the PV system installation comparatively late [6]. The amount of irradiation coming to the panel surface of the PV cells and the sun exposure time directly affect the cell performance and electricity production [7,8]. Furthermore, the amount of energy obtained from PV systems depends on many parameters, such as the system's positioning, the material used, size, and the surrounding structures [9].…”
