在本世纪内，电力需求将增加两倍，其中很大一部分需求应该由无碳能源来满足。在可再生能源中，太阳能是发展最快的；因此，一个全面而准确的太阳能系统设计方法及其与当地环境的相互作用是至关重要的。本文讨论了太阳能电池板对一个经常经历水资源紧张的未灌溉牧场的环境影响。由于太阳能电池板的存在，对小气候、土壤湿度、水分利用和生物量生产力的变化进行了量化。本研究的目的是表明，在设计太阳能农场时应考虑这些因素的影响，以利用农业和电力生产的潜在净收益。在太阳能电池阵列安装两年后，微气候站被安置在俄勒冈州立大学校园的兔子山农业光伏太阳能电池阵列中。用中子探针读数定量土壤水分。平均气温、相对湿度、风速、风向和土壤湿度存在显著差异。在整个观测期间，安装光伏太阳能电池板的地区保持了较高的土壤湿度。在光伏板下的区域，后期生物量也显著增加（生物量增加90%），光伏板下的区域显著提高了水效率（效率提高了328%）。
Power demands are set to increase by two-fold within the current century and a high fraction of that demand should be met by carbon free sources. Among the renewable energies, solar energy is among the fastest growing; therefore, a comprehensive and accurate design methodology for solar systems and how they interact with the local environment is vital. This paper addresses the environmental effects of solar panels on an unirrigated pasture that often experiences water stress. Changes to the microclimatology, soil moisture, water usage, and biomass productivity due to the presence of solar panels were quantified. The goal of this study was to show that the impacts of these factors should be considered in designing the solar farms to take advantage of potential net gains in agricultural and power production. Microclimatological stations were placed in the Rabbit Hills agrivoltaic solar arrays, located in Oregon State campus, two years after the solar array was installed. Soil moisture was quantified using neutron probe readings. Significant differences in mean air temperature, relative humidity, wind speed, wind direction, and soil moisture were observed. Areas under PV solar panels maintained higher soil moisture throughout the period of observation. A significant increase in late season biomass was also observed for areas under the PV panels (90% more biomass), and areas under PV panels were significantly more water efficient (328% more efficient).
