The building integrated photovoltaic system (BIPV) attracts attention with regard to the future of the photovoltaic (PV) industry. It is because one of the promising national and civilian projects in the country. Since land area is limited, there is considerable interest in BIPV systems with a variety of angles and shapes of PV panels. It is therefore expected to be one of the major fields for the PV industry in the future. Since the irradiation is different from each installation angle, the output can be predicted by the angles. This is critical for a PV system to be operated at maximum power and use an efficient design. The development characteristics of tilted angles based on data results obtained via long-term monitoring need to be analyzed. The ratio of the theoretically available and actual outputs is compared with the installation angles of each PV module to provide a suitable PV system for the user.

We intend to describe a 12kW building-integrated photovoltaic system which was applied into the south wall of a new building. This study showed the results that were appeared from describing the PV module manufacture and installation process, and performing generation performance analysis of BIPV system. From the result we confirmed that the generation performance of the BIPV system was changed by season. The performance ratio(PR) was about 83.6% in winter and it means that performance of this BIPV system was so good in that season. On the other hand, the PR in summer was about 75.0% dropped about 8%. It was believed that the change was influenced by the reduction of solar radiation irradiated into the PV modules by installation position and rainy spell in summer. And we also confirmed that low irradiation condition is cause of the additional loss in the total PV system. In this case, the efficiency ratio of PCS drops significantly at low input loads and the average conversion efficiency of PCS in summer was 76.4% decreased about 10% from 86% in winter.

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. And the prefab building method is very effective because the pre- manufactured building components is simply assembled to making up buildings in the construction fields especially the sandwich panel. Architecture considerations for the integration of PV module to building envelope such as building structure, construction type, safety, regulation, maintenance etc. have been carefully refelected from the early stage of BIPV module design. Trial product of BIPV module are manufactured and sample construction details for demonstration building are purposed. Therefore, this paper intends to advanced its practical use by proposing how to get integrated PV system which can be applied to prefab building material, and how to apply it.

This paper proposes photovoltaic thermal hybrid module to get the electrical and Thermal performance of building integrated photovoltaic(BIPV) system. BIPV system is decreased the system efficiency because output of PV is decreased by the thermal rising on generating. In order to improve the efficiency of BIPV module, water cooling system is applied and generated thermal is used the warm water system. Water cooling system uses the flux control algorithm considering water temperature and power loss. Electrical and thermal performance of proposed photovoltaic thermal hybrid module is confirmed through the actual experiment and herby proved the valid of this paper.

By the skyscraper building, increase of skin area and expansion of curtain wall system will be the important factors of acceleration in extending supply of BIPV system. In the future interior environmental evaluation is not a necessary to the residents but an essential term which will bring enormous influence. In the interior environmental evaluation, natural light will let the residents with direct contact with outside circumstances and make them feel opened. also only the daylight has radiant energy and color rendering that will have a great influence to residents' mental, operation efficiency and advancing productivity. This research compares and analyzes BIPC system in office spaces with two general sunlight's module. In addition to natural light's efficiency for BIPC system's comfort and confirmed economical efficiency will be applied to basic research data. Hence forth, ensuring indoor intensity of illumination and controlling light system to reducing energy research data will be demanded to increase the amount of supplying BIPC system. Also continuance research in the possibility of applying BIPC system in various buildings, room temperature affected by location of windows and its condensation, and economical evaluation will be required.

The purpose of this study is to provide foundational data for expansion of solar generation in building application, a clean energy, by introducing applicability of solar power generation system on roofs of industrial buildings and computing expected amounts of power and carbon dioxides reduction. As methodologies of this study, after reviewing 120,000 domestic factories to verify the BIPV feasibility for industrial building sthrough theoretical considerations of solar generation system, we calculated BIPV application methods and subsequent expected power generation quantity and carbon dioxide reductions through roof type analysis. we analyzed four cases of expected power generation amounts of solar batteries according to application methods, and when considering that the main type of roofs are slant roofs according to the investigation result about roof forms of domestic industrial complexes, we believe that the module angle of a slant roof around $17^{\circ}$(case3) is most suitable for the application. Finally, we came up with 517,944[TOE] as the corresponding petroleum tonnage based on this computed expected power generation amount and the amount of 1,214,836[$tCO_2$] carbon dioxide reductions by calculating them by energy sources.

The range and method of this research is to establish monitoring system and analysis the data from the monitoring system to evaluate the performance of PV windows that have thin film of solar battery. We should evaluate the insolation according to the position of PV window, output, and surface temperature according to months and seasons so that we can figure out the relationship between these. And we should investigate the relationship between performance and efficiency according to incidence angle and sky condition so that we can figure out the correlation between factors and performance.

In building-integrated photovoltaic (BIPV) systems, power generation functions are integrated into building functions by installing solar modules in combination with building materials. While this integration appears to be attractive, a design method is needed to achieve maximum power generation. Previously, the influence of the design elements on power generation was analyzed by computer simulations and demonstration tools. On the other hand, problems remain due to the inaccuracy of power generation analysis and relationship analysis, and limited demonstration. To solve this problem, this paper proposed the use of an extended demonstration mock-up. The mock-up was designed and constructed by implementing the design elements of the module types, installation angles, and direction. The actual operation data for one year were analyzed to evaluate the effects of the design elements on power generation. These results can be used to determine the feasibility of future BIPV systems and the optimal selection of system design elements.

태양광발전은 태양의 복사에너지를 직접 전기에너지로 변환하는 시스템으로 가동부분이나 열기관이 없어 수명이 길고 운전과 유지보수가 용이하며 모듈로 구성되기 때문에 수요나 지형에 맞게 설계할 수 있다. 이러한 특성으로 인해 태양광 발전은 차세대 성장 에너지원으로 각광 받고 있으며, 최근 문제되고 있는 지구환경문제 해결에도 부합할 수 있는 잠재력을 갖고 있다. 또한 계통 연계형 태양광 발전시스템의 확대 보급시 태양광 발전시스템의 출력특성에 의한 기존 전력계통의 피크전력을 감소시키는 효과도 기대할 수 있다. 국내 태양광발전은 정부 지원정책에 힘입어 지속적으로 보급이 확대되고 있으며, 2009년도 기준으로 약 400 MWp 이상의 설비가 전력시장에 진입하여 상업 운전중에 있다. 태양광발전시스템은 육상에 설치하는 것이 주류를 이루고 있었으나 태양광 입지조건에 적합한 부지를 확보하는 것이 쉽지않기 때문에 최근에는 건물옥상이나 벽에 설치하는 사례가 증가되고 있다. 본 논문에서는 한전전력연구원(대전시 유성구 문지동)의 건물옥상에 설치되어 운전하고 있는 9.52kW급 BIPV 형식의 태양광발전시스템을 대상으로 2010년도 1년간의 운전특성에 대하여 분석 평가하고 이를 통해 BIPV시스템의 운전에 대한 기초자료를 제시하고자 한다.
