Contemporary Materials, 2013

The paper focuses on the analysis and assessment of the possibilities of building integrated PV (BIPV) systems of 1 kW electricity generation in Banja Luka in the Republic of Srpska. Special attention was paid to average monthly sum of global solar irradiation per square meter received by horizontally, optimally and vertically inclined and south-oriented solar modules of 1kW BIPV system and total for year electricity production from 1 kW BIPV system with horizontally, optimally and vertically inclined and southoriented solar modules of different materials for Banja Luka, obtained by PVGIS. In addition, comparison was made of total for year electricity production of 1kW BIPV system with horizontal, optimal and vertical inclination and south-oriented solar modules of monocrystalline silicon, CdTe and CIS in Banja Luka. The research estimated the proportion of BIPV systems power generation according to different types of PV modules and installation methods. The data could serve as a useful reference for the application of BIPV systems in buildings.

Building integrated photovoltaic (BIPV) system is a new and modern technique for solar energy production in Kandahar. Due to its location, Kandahar has abundant sources of solar energy. People use both monocrystalline and polycrystalline silicon solar PV modules for the grid-connected solar PV system, and they don’t know that which technology performs better for BIPV system. This paper analysis the parameters, described by IEC61724 “Photovoltaic System Performance Monitoring Guidelines for Measurement, Data Exchange and Analysis” to evaluate which technology shows better performance for the BIPV system. The monocrystalline silicon BIPV system has a 3.1% higher array yield than the polycrystalline silicon BIPV system. The final yield is 0.2% somewhat higher for monocrystalline silicon than polycrystalline silicon. Monocrystalline silicon has 0.2% and 4.5% greater yearly yield factor and capacity factors than polycrystalline silicon respectively. Monocrystalline silicon shows 0.3% bet...

Temperatures of c-Si, pc-Si and a-Si PV modules making part of a roof in a building or hanging outside windows with various inclinations were measured with respect to the Intensity of the solar radiation on them under various environmental conditions. A relationship coefficient f was provided whose values are compared to those from a PV array operating in a free standing mode on a terrace. A theoretical model to predict f was elaborated. According to the analysis, the coefficient f takes higher values for PV modules embedded on a roof compared to the free standing PV array. The wind effect is much stronger for the free standing PV than for any BIPV configuration, either the PV is part of the roof, or placed upon the roof, or is placed outside a window like a shadow hanger. The f coefficient depends on various parameters such as angle of inclination, wind speed and direction, as well as solar radiation. For very low wind speeds the effect of the angle of inclination, , of the PV module with respect to the horizontal on PV temperature is clear. As the wind speed increases, the heat transfer from the PV module shifts from natural flow to forced flow and this effect vanishes. The coefficient f values range from almost 0.01 m 2o C/W for free standing PV arrays at strong wind speeds, v w >7m/s, up to around 0.05 m 2o C/W for the case of flexible PV modules which make part of the roof in a BIPV system

The energy and environmental crisis are increasing every day. Where the focus of energy production is being driven by renewable energy sources. Solar energy represents an inexhaustible source of energy that can be used almost anywhere. This paper presents the analysis of the energy performance of photovoltaic (PV) and photovoltaic thermal (PVT) panels for the climatic conditions of Kosovo. The site analyzed is the building of the University Clinical Center in Prishtina. The analysis included five types of photovoltaic modules from where the highest energy performance is shown by the PVT panels with a theoretical power produced during July 273 W while during December 78 W. Also, with an efficiency of 59.77% during the month of December and an efficiency of 17.08% during the month of July. While among the other types of PV panels, polycrystalline panels have the best performance with a theoretical power of 252 W during July and 72 W during December. But they showed an efficiency of 48.78 during the month of December and an efficiency of 13.94 during the month of July. The analysis made is presented in an analytical and detailed manner for certain climatic conditions of annual measurements.

The idea of combining both thermal and photovoltaic collectors in hybrid photovoltaic-thermal (PV-T) modules actually shows a great potential for integration on facades and rooftops of buildings, mainly because of the reduced available space and the benefits of the on-site electricity and thermal generation. The objective of this work is to compare the real performance (experimental data obtained under real sun during a year) of a commercial hybrid PV-T system vs. a simple PV system using microinverters, assessing the suitability of one-unit hybrid PV-T systems vs. two separated units-PV systems + Thermal systemsfor building integration. The combined efficiency over the span of a full day could reach values up to 80%, but this apparent high value needs to be analysed in detail. From the experimental results, it can be observed that both systems, PV and PV-T, have a good electrical performance. But the PV-T system output does not benefit from the lower module temperatures that it should achieve from the active cooling in its back, presenting the same performance as the simple PV system. Regarding the microinverters configuration performance, it has been very positive working with high efficiencies above 96%, justifying its use in this type of applications. In conclusion, the commercial PV-T system has not performed as expected, showing problems with the integration of the active cooling in the back of the PV modules. At this moment, and despite the potential of PV-T systems for BIPV due to space limitations, commercial PV-T systems are still far from PV and Thermal systems using separately.

In all over the world, huge parts of energy are consumed by buildings. Building integrated photovoltaic (BIPV) systems have attracted much attention with the purpose of providing energy demand of buildings. This paper introduces the examinations of BIPV system on a residential building under different climatic conditions of Iran by considering different PV modules. The building orientation has been analysed in order to find higher efficiency rate of PV modules through DesignBuilder. It was found the maximum rate of energy generation for all three cities occurs in south side of the building. Also for Tehran and Tabriz the minimum ratio of energy consumption is at the angle of 180° while for Bandar Abas it is in north side. Moreover, applying Cd-Te modules contribute to reducing payback time.
