In South Korea, small photovoltaic equipment is increasingly adopted in more detached houses on the constant basis. With this broader use of small photovoltaic equipment, its systematic maintenance becomes all the more necessary. However, photovoltaic facility maintenance has been concentrated solely on large-scale solar energy generation plants in the country while hardly covering smaller facilities. In this research, the JEM rule and extant maintenance company services were analyzed to develop a proper maintenance model for small photovoltaic equipment. The maintenance service procedures designed herein are as follows: A small photovoltaic equipment user chooses a maintenance company and signs a contract. Once a contract is made, the Korea Energy Management Corporation provides a certain kind of incentive to the company. The company provides maintenance service to the user and receives a service fee. If such a maintenance service model is in place, small photovoltaic equipment efficiency is expected to increase and users could receive systematic maintenance services. Also the new creation of small photovoltaic equipment maintenance service would form a new market to generate more jobs for the society.

With the government's support for new and renewable energy, photovoltaic equipment has rapidly been supplied. However, compared to supply rate, maintenance has not supported enough and relevant research has not much conducted. Therefore, the purpose of this study is to analyze maintenance effectiveness of photovoltaic equipment. What is the most important in maintenance effectiveness is a rise in power generation. It was estimated that if photovoltaic equipment for detached houses is maintained well, power generation increases by 4.0% at least, and by 6.5% on average. As a result, it was analyzed that it is necessary to maximize the effectiveness of the government's budget investment through well maintenance of photovoltaic equipment for detached houses.

The Korean government pushed ahead various policies to disseminate photovoltaic (PV), wind power, small hydro, bio-fuel, etc. Renewable energy system (RES) budget of the Korean government increased from 118 billion won of 2003 to 876.6 billion won of 2010. The R&D budgetary supports for RES increased by 6.8 times in the period 2003-2010. It is necessary to confirm RES budget expenditure that renewable energy promotion policy makes good performance evaluated in quantity level. This paper made Input-Output Table 2009 contains photovoltaic power generation equipment industry as a dependent sector and analyzed induced production effect by demand of photovoltaic power generation equipment industry. From the empirical analysis result, additional demand in photovoltaic power generation equipment induced 1.932 times of induced production in Korea. Each of industry sector has positive induced production from the additional demand in photovoltaic power generation equipment. Renewable energy promotion in photovoltaic power generation is considered together with industry policy as the option to sustain economic growth.

정부의 신재생에너지에 대한 지원으로 태양광발전설비의 보급이 급속하게 증가하고 있다. 그러나 보급량에 비해서 유지관리에 대한 지원이나 연구는 부족한 실정이다. 대규모 발전시설은 유지관리가 이루어지고 있지만, 주택용과 같은 소형 설비는 유지관리가 거의 이루어지지 않고 있다. 본 연구는 주택용 태양광발전설비를 중심으로 유지관리의 효과를 분석하는 것을 목적으로 하였다. 주택용 태양광발전설비의 유지관리는 거의 이루어지지 않는 것으로 조사되었다. 유지관리의 효과 중에서 가장 중요한 것은 발전량의 증가이다. 주택용 태양광발전설비의 유지관리가 이루어진다면, 발전량이 최소 6.5% 정도 증가할 것으로 예측되었다. 이것은 주택용 태양광발전설비를 약 9,700세대에 추가로 보급한 것과 같은 효과와 같다. 따라서 태양광발전설비에 대한 유지관리를 통하여 정부예산 투자의 효과를 극대화할 필요성이 있는 것으로 분석되었다.

Small photovoltaic equipment spreads to the detached house owing to the support of government. This study analyzed the payback period of small photovoltaic equipment, and presented a plan of spreading PV equipment by electricity consumption according to the results. The results of payback period analysis showed that a household of 500kWh or above in the average monthly electricity consumption could produce an economic effect without the subsidies of government, and a household of 300kWh or above could secure economical efficiency in case of receiving the subsidies of government and municipality. However, it was shown that the economic effect was not large in case of a household of less than 250kWh. Therefore, the analysis showed that it would be necessary to be supported by additional subsidies or to develop a new supporting policy with regard to a household of less than 250kWh.

This study investigated power generation of photovoltaic equipment at detached houses. The study estimated monthly mean generation according to maintenance conditions that included module cleaning, inspection into generation, cleaning of module and photovoltaic generation. At analysis upon generation, households with periodical module cleaning and inspection into generation, clean module and good generation conditions had high generation. 20-years of PV equipment life varied much depending upon maintenance conditions. Users should keep module clean and inspect generation regularly and put PV equipment at the place with good solar radiation.

2011년 10월 국내 최초로 다목적댐 저수지에 100kW급 수상태양광발전 상용화 실증 플랜트가 합천댐에 설치되었다. 수상태양광발전 설비는 육상에 설치하는 태양광발전 설비와는 달리 수상부유체, 계류장치, 수중케이블 등 설치에 많은 어려움이 있다. 특히 수상이라는 환경적 제약으로 인해 육상 태양광 시공 방법으로 공정 관리를 할 수 없는 많은 변수가 속출한다. 수상태양광발전의 구조체는 수상태양광 모듈 및 기타 전기설비를 수상에 부상시키기 위한 설비로서 바람이나 태풍 등 기상환경에 견뎌야 하고 수질에 악영향을 미치지 말아야하며 시공성, 경제성 등 종합적인 고려가 필요하다. 본 논문에서는 100kW 수상태양광 시공사례를 바탕으로 수상태양광의 구조체, 계류장치, 수중케이블, 전력설비 및 원격감시제어시스템의 시공기술에 대한 기초자료를 제공하였다. 본 연구에서 시공된 100kW 수상태양광은 현재 평균 설비이용률 15%로 운영중에 있다.

Photovoltaic and Thermal collector (PV/T) systems are renewable energy devices that can produce electricity and heat energy simultaneously using solar panels and heat exchangers. Since PV/T systems are exposed to the outdoors, their reliability is affected by various environmental factors. This paper presents a reliability test for a PV/T system and evaluates the test results. The reliability assessment entails performance, environment, safety, and life tests. The factor that had the greatest influence on the life of the system was the hydraulic pressure applied to the heat exchanger. A test was conducted by repeatedly applying pressure to the PV/T system, and a reliability analysis was conducted based on the test results. As a result, the shape parameter (β) value of 5.6658 and the B10life 308,577 cycles at the lower 95% confidence interval were obtained.

본 연구는 단독주택용 태양광발전설비의 사용자 요구사항 분석을 목적으로 하였다. 분석을 위해 태양광발전설비를 설치한 202가구를 방문하여 설문을 실시하였다. 설문 결과 사용자들은 '자부담금액 축소'와 '유지관리서비스'를 주로 요구하였다. 또한 '태양광발전설비에 대한 교육'을 실시할 경우 이에 참여하고 싶은 의사도 높게 나타났다. 태양광발전설비의 설치 실태를 파악한 결과는 다음과 같았다. 태양광발전설비를 설치한 위치 중 옥상에 설치한 가구가 54%로 가장 많았다. 태양광 모듈이 설치된 각도는 $25-35^{\circ}$의 범위가 가장 많았으며, 설치방향은 남향이 93%의 비율을 차지하였다. 조사된 가구의 월평균 발전량 평균은 약 320kWh이다. 향후에는 본 연구에서 나타난 사용자 요구사항을 해결할 기술과 정책에 대한 연구가 필요하다고 판단된다.
