주변 건축물 변화로 인한 태양광발전 효율 저하의 손해보상 프로세스 연구: 법적 · 이론적 고찰 및 사례 분석을 중심으로

As part of climate change mitigation and energy transition policies, the importance of building photovoltaic (PV) systems is increasing with the expansion of zero-energy buildings. These systems are gaining attention as key elements in enhancing the energy self-sufficiency of buildings. However, the trend towards high-rise and high-density urban buildings results in reduced power efficiency due to shading for existing PV systems, which reduces their power efficiency. PV systems are vulnerable to potential conflicts and financial setbacks owing to a lack of clear legal protections and compensation procedures to address power efficiency losses due to shading. This study examines the legal and institutional aspects of securing and protecting solar irradiance for building PV systems and proposes solutions to these issues. The methodology includes a comparative evaluation of relevant domestic and international policies, literature reviews, and case study analyses. The overall aim is to develop and suggest comprehensive procedures for damage compensation related to reduced PV power efficiency caused by changes in surrounding buildings. The results of this study can be used as basic data for establishing future policies, improving the legal system to protect the rights of PV system owners, and establishing efficient dispute resolution procedures.
