Whether it is for the purpose of reducing of the pollution of PM2.5 or reaching the goal of non-nuclear homeland, using solar energy to generate electricity has become an important policy goal in our country so as to promote the development of renewable energy. The “Act of Renewable Energy Development” in our country advocates the roofs of legal structures equipped with solar photovoltaic power generation equipment. Subsequently, the Agriculture Commission of the Executive Yuan, following the national renewable energy policy, issued the “Regulations on the Permission to Use Agricultural Land for Agricultural Facilities” and added Chapter IX of green energy facilities. However, the development of technology ignored, many legal disputes have been triggered in the process of practice. The conflict in legal norms between “agricultural security” and “green energy development” must be resolved. Thus, it is necessary for the law to integrate and coordinate the two.
