This study has been carried out empirical research on Transparent Thin-film BIPV modules, BIPV modules installed on the exterior of the building are applied a laminated module 1kWp, double-glazing module 3kWp and triple-glazing module 1kWp. Applied to the total capacity of BIPV modules are 5kWp. In this study, design and construction process of BIPV systems is presented. In addition, through monitoring of the BIPV system, the temperature and the power characteristics of each module were analyzed. During the measurement period, the module temperature measurement results, the maximum surface temperature of $51.5^{\circ}C$ triple-glazing BIPV module showed the highest, followed by double-glazing BIPV module $49.1^{\circ}C$, $44.7^{\circ}C$ laminated modules, respectively. Power output results, the daily average double-layer modules showed 4.10kWh/day, triple-glazing module 1.57kWh, respectively 1.81kWh laminated modules. In particular, the power efficiency of triple-glazing BIPV module was lower than the power efficiency of the laminated BIPV module. This phenomenon is considered to be affected by the module temperature. In the future, BIPV modules in this study the relationship between module temperature and power characteristics plans to identify.

This study has analysed power output characteristics of transparent thin-film PV module depending on incidence angle and azimuth. The experiment results showed power outputs of transparent thin-film PV module applied to full-scale mock up model on slope of $90^{\circ},\;30^{\circ},\;0^{\circ}$ to the south. The simulation results was evaluated power outputs of transparent thin-film PV module depending on incidence angle and azimuth after calibrating the experimental and computed data. As a result. the best power output performance of transparent thin-film PV module was obtained at slope of $30^{\circ}$ to the south, producing the annual power output of 977kWh/kWp. The annual power output data demonstrated that the PV module with a slope of $30^{\circ}$ could produce a 68 % higher power output than that with a slope of $90^{\circ}$ with respect to the inclined slope of the module, Furthermore, the PV module facing south showed a 22 % higher power output than that facing to the east in terms of the angle of the azimuth, Specipically. the varying power output with incidence angle of PV module can be resulted from the influence of incidence angle modifier of glass on PV module. That is, the solar energy transmission can be reduced as an increase of incidence angle of PV module. Therefore, when the inclined slope of the PV module was over $70^{\circ}$ there was a significant reduction of power output, and this was caused by the decrease of solar energy transmission in the transparent thin-film PV module.

The integration of PV modules into building facades or roof could raise their temperature that results in the reduction of PV system's electrical power generation. Hot air can be extracted from the space between PV modules and building envelope, and used for heating in buildings. PV/thermal collectors, or more generally known as PVT collectors, are devices that operate simultaneously to convert solar energy from the sun into two other useful energies, namely, electricity and heat. This paper compares the experimental performance of BIPVT((Building-Integrated Photovoltaic Thermal) collectors that applied on building roof and facade. There are four different cases: a roof-integrated PVT type and a facade-integrated PVT type, the base models with an air gap between the PV module and the surface, and the improved models for each types with aluminum fins attached to the PV modules. The accumulated thermal energy of the roof-integrated type was 15.8% higher than the facade-integrated regardless of fin attachment. The accumulated electrical energy of the roof-integrated type was 7.6% higher, compared to that of the facade-integrated. The efficiency differences among the collectors may be due to the fact that the pins absorbed heat from the PV module and emitted it to air layer.

This study evaluated the influence of temperature on the PV module surface on power output characteristics, especially for an amorphous transparent thin-film PV module which was applied to a full-scale mock-up model as building integrated photovoltaic system. The tested mock-up consisted of various slopes of PV module, facing to the south. The annual average temperature of the module installed with the slope of $30^{\circ}$ revealed $43.1^{\circ}C$, resulting in $7^{\circ}C$ higher than that measured in PV modules with the slope of $0^{\circ}$and $90^{\circ}$ did. This $30^{\circ}$ inclined PV module also showed the highest power output of 28.5W (measured at 2 PM) than other two modules having the power output of 20.4W and 14.9W in the same time for $0^{\circ}$ and $90^{\circ}$ in the slope, respectively. In case of the $30^{\circ}$ inclined PV module, it exhibited very uniform distribution of power output generation even under the higher temperature on the module surface. Consequently, the surface temperature of the PV module analyzed in this study resulted in 0.22% reduction in power output in every $1^{\circ}C$ increase of the module surface temperature.

BIPV(Building Integrated PV) system can expect dual effects that reduce expenses for establishment of PV system by adding new function as outer covering material of building expect producing the electricity. In case of PV(photovoltaic system) there are many generation differences according to the exterior environmental facts(solar cell array, design and installation condition of interactive inverter system). In this paper, we compared constitute factors of 3kW BIPV(solar cell module, inverter), operating characteristic and total system characteristic(utilization, generation efficiency, loss fact) and found out long time operating data using a watch instrumentations. By use of long time operating result, compare a totally operating characteristics, and we proposed a next building application of BIPV. BIPV system that is proposed in this paper, was established in Solar Energy research center of Chosun University, composed with system. The objective of this paper, is to provide a efficient BIPV design method through the considerations for the integration of PV system.

Purpose: This study was on the economic feasibility of BIPV system, focused on comparison with construction cost of BAPV system depend on roof finishing materials, and to suggest basic data on the construction cost. Method: Construction cost of BAPV system was calculated, by selecting asphalt single, flat type roof tile, color steel plate, titanium zinc plate as roof finishing material of residential building and by sum up each cost for roof finishing construction and cost for 3kWp-volumed PV module installation. Also, the economic feasibility was analysed quantitatively by comparing the cost for BIPV system construction, installing same volumed PV module instead of roof finishing materials. Result: 1. By installing BIPV system instead of the roof finishing material, the cost of construction falls ; about 19% in case of the titanium zinc plate, which is the most expensive, and about 11% in case of the color steel plate. 2. Reducing amount of the construction cost gets larger because of installing BIPV module instead of the roof finishing material, as the construction cost for roof finishing material gets higher ; therefore, it is more economical than BAPV system in terms of whole cost of construction.

Whilst there are growing interests in pursuing energy efficiency and zero-energy buildings in built environment, it is widely recognised that Building-Integrated Photovoltaic (BIPV) is one of the most promising and required technologies to achieve these goals in recent years. Although BIPV is a broadly utilized technique in variety of fields in built environments, it is required that generation of BIVP should be analysed and calculated by external specialists. The aim of this research is to focus on developing a new diagram for prediction of the pre-estimation model in early design stage to harness solar radiation data, PV types, slopes, azimuth and so forth. The results of this study show as follows: 1) We analysed 162 districts in a national level and the examined areas were categorised into five zones. The standard deviation of the results was 2.9 per cent; 2) The increased value of solar radiation on a vertical plane in five categorised zones was 42kWh/m3, and the result was similar to the average value of 43.8kWh/m3; and 3) The pre-estimation of diagram was developed based on the categorisation of zones and azimuth as well as the results of the developed diagram showed little difference compared to the previously utilised method. The suggested diagram in this paper will contribute to estimate BIPV without any external contribution to calculate the value. Even though the result of this study shows little difference, it is required to investigate a number of different variables such as BIPV types, modules, slope angle and so forth in order to develop an integrated pre-estimation diagram.
