  • The application of photovoltaics into building as integrated building components has been paid more attention worldwide. Photovoltaics or solar electric modules are solid state devices, directly converting solar radiation into electricity; the process does not require fuel and any moving parts, and produce no pollutants. So, the purpose of this research is to present how to get PVIB which can be applied building facade and how to apply it. From the basis of these results this study will intend to develop an integrated for optimal design of PV System.

  • The application of Photovoltaic (PV) power in the building sector, is expanding as part of the ongoing energy transition into renewables. The article addresses the question of sustainability of energy generated from PVs through an environmental assessment of a building-integrated PV system (BIPV) connected to the grid through net metering. Employing retrospective life cycle analysis (LCA), with the CCaLC2 software and ecoinvent data, the article shows that the carrying structure and other balance of system (BOS) components are responsible for a three times higher energy payback time than the literature average. However, total environmental impact can be lowered through reuse or reinstallation of PVs on the same building structure after the 30-year interval. Further ways to improve environmental efficiency include identifying the most polluting materials for each LCA parameter. The results of this study are of interest to researchers and producers of PVs and organizations investing and promoting decentralized power production through PVs.

  • This paper proposes a novel sensorless maximum power point tracking (11PPT) algorithm for PV systems. The method is based on dividing the operating time into several intervals in which the PV terminals are short circuited in one interval and the calculated short-current of the PV is obtained and used to determine the optimum operating point where the maximum output power can be obtained. The proposed MPPT algorithm has been introduced into a current-controlled boost converter whose duty ratio is controlled to the maintain MPP condition. The same sequence is then repeated regularly capturing the PV maximum power. The main advantage of this method is eliminating the current sensor. Meanwhile, this MPPT algorithm reduces the power oscillations around the peak power point which occurs with perturbation and observation algorithms. In addition, the total cost will decrease by removing the current sensor from the PV side. Finally, simulation results confirm the accuracy of the proposed method.

  • 대부분의 건물일체형 태양광 발전 시스템(BIPVS; Building Integrated Photovoltaic System)은 건물의 옥상이나 벽면에 설치된다. 따라서 BIVPS의 설치 위치 선정 시 고려해야할 가장 중요한 요소는 주변 건물에 의한 그림자 영향이다. 그러나 지면 위에 있는 방음벽에 태양광 시스템을 설치할 경우, 그림자는 주변 건물은 물론 가로수에 의해서도 생성된다. 따라서 방음벽 일체형 태양광 발전 시스템(SIPVS; Soundproof wall Integrated Photovoltaic System)의 설치 적합지를 선정하기 위해서는 BIPVS의 경우와 다른 데이터 모델 및 알고리즘이 필요하다. 본 논문에서는 수치표면모형 기반의 방음벽 일체형 태양광 시스템의 설치 적지 분석을 다룬다. 첫째, 설치 후보지(태양광 패널)의 연간 태양 입사각과 고도각을 계산한다. 둘째, 설치 후보지의 시간대 별 그림자 생성 여부를 수치표면모형을 이용하여 결정한다. 셋째, 그림자가 생성되지 않은 시간대의 태양 입사각을 이용하여 일사량을 계산한다. 일사량의 연간 누적 비교를 통하여 일사량이 충분한 곳을 SIPVS의 설치 적합지로 결정할 수 있다. 제안된 알고리즘은 시작품 형태로 구현(Java Program)되었다. 실험 결과, 총 아홉 곳의 후보지에 대한 설치 적합도의 순서를 결정할 수 있었다. 제안된 알고리즘은 건물의 낮은 위치에 설치할 BIPVS의 적정 설치위치 및 기대 전력 생산량의 계산에도 활용될 수 있을 것이다.

  • Nowaday, The Sustainable Development about global environment is the most important subject. In urban environment, a variety of the nature energy utilization such as the solar energy are the most efficient solution to solve this issue. One of these efficient solutions, a photovoltaic system using sunlight has been introduced to the building with an advantage such as cost-effective, safe for using and good for environment friendly in light with energy utilization. Recently, many of the apartment housings are built in domestic country. The apartment buildings have been constructed since early of 1970's. now apartment is taking over 50% out of entire housing in korea. The apartment housing applying to a photovoltaic system has been extensively studied in the foreign country but our county runs short. So, It was necessary to technical development of PV application which is suitable in Korean house culture. The objective of this study is to develop the building integrated PV application method for apartment building.

  • The temperature of PV modules that integrated into building facades or roof increases that could reduce the electrical efficiency of the PV system. In order to incresae PV system's efficiency it is very important to remove the heat from the PV modules. For this purpose, hot air can be extracted from the space between PV modules and building envelope, and used for heating in buildings. The solar collector utilizing this thermal effect is called photovoltaic-thermal(PVT) solar collector. This paper compares the experimental performance of building-integrated PVT collectors that applied on building roof and facade. There are two different case: a roof-integrated PVT type and a facade-integrated PVT type. The experimental results show that the collected thermal energy of the roof-integrated type was 24% higher, compared to that of the facade-integrated.

  • Building Integrated PV(BIPV) is one of the best fascinating PV application technologies. To apply PV module in building, various factors should be reflected such as installation position, shading, temperature, and so on. Especially a temperature should be considered, for it affects both electrical efficiency of a PV module and heating/cooling load in a building. It reports the effect of thermal characteristics of the PV module on generation performance. The study was performed by monitoring the temperature and experiment. The results showed that 1 degree temperature rise reduced about 0.48% of output power.

  • Building integrated photovoltaic(BIPV) system operates as a multi-functional building construction material. They not only produce electricity, but also are building integral components such as facade, roof, window and shading device. As PV modules function like building envelope in BIPV, combined thermal and PV performance should be simultaneously evaluated. This study is to establish basic Information for designing effective BIPV by discovering relations between temperature and generation capability through experiment when the PV module is used as roof material for houses. To do so, we established 3kW full scale mock-up model with real size house and attached an PV array by cutting in half. This is to assess temperature influence depending on whether there is a ventilation on the rear side of PV module or not.
