; (II) regional needs and variations in climate, soils, costs, existing infrastructure, and market access for agrivoltaic system products; (III) existing State and local agrivoltaic system policies and definitions; and (IV) such other factors as the Secretary determines to be appropriate. (b) Study (1) In general The Secretary, in coordination with the Secretary of Energy and relevant experts, shall conduct a study on agrivoltaic systems that shall include— (A) a review of the current research and gaps in research relating to the regional compatibility of different species of livestock with different agrivoltaic panel and agrivoltaic system designs, including— (i) the optimal height of and distance between solar panels for— (I) livestock grazing; and (II) shade for livestock; (ii) manure management considerations; (iii) fencing requirements; (iv) other animal handling considerations; and (v) the incorporation of apiculture; (B) an assessment of animal breeding research needs with respect to beneficial and compatible characteristics and behaviors of different species of grazing animals in agrivoltaic systems; (C) a review of the current research and gaps in research relating to the regional compatibility of different crop types with different agrivoltaic system designs, including— (i) the optimal height of and distance between solar panels for— (I) plant shading; and (II) farm equipment use; (ii) the impact on crop yield; (iii) the impact on soil moisture and water availability; and (iv) market opportunities to sell crops at a premium price; (D) an assessment of plant breeding research needs with respect to beneficial and compatible characteristics of different crops, including specialty and perennial crops, in agrivoltaic systems; (E) a risk-benefit analysis of agrivoltaic systems in different regions of the United States, including a comparison between the total greenhouse gas impact of agrivoltaic systems and solar energy systems that displace agricultural production
