초록

본 연구에서는 개발 중인 초음파 기술을 적용한 태양광발전설비 세척 장치의 경제성 분석을 위하여 AHP 편익-비용을 분석하였다. 초음파 기술을 적용한 태양광발전설비 세척장치와 유사한 특성을 가지며, 국내에서 널리 사용되고 있는 태양광발전설비 세척 장치를 비교 대상으로 선정하여 상대적인 편익-비용 분석 값을 비교하였다. 두 비교 대상의 편익, 비용을 정량적, 정성적으로 분석하기 위하여 각각의 측면의 상위계층과 하위평가항목을 도출하고, 하위 평가항목에 대한 평가기준을 도출하였다. 도출된 평가기준을 기반으로 15인의 전문가 인터뷰를 수행함으로써 두 비교 대상의 편익, 비용 가중치를 계산하였다. 분석 결과, 초음파를 사용한 태양광발전설비의 편익-비용 분석 값은 1이상으로 비용대비 이익이 더 높을 것으로 예상되었고, 비교 대상의 편익-비용 분석 값보다 약 1.6배 높았다. 이는 경제적인 측면에서 초음파를 적용한 태양광발전설비 세척 장치의 개발 가치가 있다는 것은 의미한다.

This study aims to analyze the benefit-cost of the cleaning device for photovoltaic power generation systems in buildings in order to check its economic feasibility. A product, which has similar characteristics to the ultrasound-based cleaning device and is widely used in South Korea, was selected to compare with the benefit-cost value of the ultrasound-based cleaning device in this study. In order to quantitatively and qualitatively analyze benefit and cost aspects of the two products, categories and evaluation factors of each aspect as well as evaluation criteria were identified. Based on the identified evaluation factors and criteria, this study conducted face-to-face interviews with 15 experts to measure weights of benefit and cost aspects of the products. As the results, the total benefit weight of the ultrasound-based cleaning device was larger than its total cost weight since the benefit-cost value was greater than 1, which was 1.6 times of that of to compared product. Therefore, from the economic perspective, it is worth to develop the cleaning device for photovoltaic power generation systems applying ultrasound technology.
