In this study, Solar Thermoelectric Generator Assisted Water Pump (STEGWP) for agricultural irrigation systems has been proposed and analyzed. A single module solar thermoelectric generator cell (STEGC) with average solar radiation value of Turkey was designed, and its electrical parameters were calculated in the laboratory environment. By using a tar-coated, heat-absorbing copper plate with a radiation value of 578 W/m², the hot surface temperature was measured as 94 °C. The cold surface temperature, which is cooled by well water, was measured as 21 °C. A solar thermoelectric generator panel (STEGP) that corresponds to a 275 W photovoltaic (PV) panel was simulated by using the electrical module parameters, and the cost was calculated. While 187 W/m² of power is obtained in PV panel, STEGP provides 1000 W/m². On the other hand, while the cost of energy in PV panel is 0.72 $/W, STEGP costs 2.87 $/W. Economical analysis of an exemplary irrigation system for PV, STEGP, and conventional diesel generators has been performed. The proposed system uses its operating material for cooling purposes, and the cooling material never gets heated as the circulation is single-sided. The proposed system can readily compete with PV panels with increased quality materials used in modules.

在这项研究中，提出并分析了用于农业灌溉系统的太阳能热电发电机辅助水泵（STEGWP）。设计了具有土耳其平均太阳辐射值的单模太阳能热电发电单元（STEGC），并在实验室环境中计算了其电参数。通过使用辐射值为578W / m ²的涂有焦油的吸热铜板，测得的热表面温度为94℃。经井水冷却的冷表面温度测得为21°C。使用电气模块参数模拟了与275 W光伏（PV）面板相对应的太阳能热电面板（STEGP），并计算了成本。而187 W / m ²在PV面板中获得最大功率时，STEGP可提供1000 W / m ²。另一方面，PV面板的能源成本为0.72 $ / W，STEGP的成本为2.87 $ / W。已对PV，STEGP和常规柴油发电机的示例性灌溉系统进行了经济分析。提议的系统将其工作材料用于冷却目的，并且由于循环是单面的，因此冷却材料永远不会被加热。所提出的系统可以很容易地与组件中使用的具有更高质量材料的PV面板竞争。
