摘要： This paper calculates the most optimum angle for solar panel for 365 days of the year individually using geographical location of Dhaka, Bangladesh.

Method to improve performance of building integrated photovoltaic thermal system having optimum tilt and facing directions
摘要： A building integrated photovoltaic (BIPV) system can be installed at optimum tilt and orientation angle to maximize the electrical output. PV output is negatively correlated with the increase in the PV panel temperature. This paper aims at investigating the influence of water flow over the BIPV roof of a two-storied single-family house on the performance of the proposed optimally tilted semi-transparent BIPV thermal system having different facing directions. The periodic nature of insolation, ambient air temperature, BIPV cell temperature, slab temperature, water flow temperature and room temperature have been considered while solving energy equilibrium differential equations. The insolation values used in the energy equilibrium equations are computed employing periodic HDKR (Hay, Davies, Klucher and Reindl) model, which is based on anisotropic sky concept. Results indicate that the average BIPV cell temperature is reduced annually by approximately 10 °C and efficiency is enhanced by 6% when a water flow rate of 1.1 kg s?1 is provided over the BIPV roof. It is also observed that on the most critical day of the year, the temperature of outlet water is 11.5 °C higher than that of inlet water temperature which resulted in 4 kW extraction of exergy.

Performance enhancement of multi-crystalline silicon photovoltaic modules using mirror reflectors under Western Himalayan climatic conditions
摘要： Silicon photovoltaic modules are widely used in solar power plants worldwide, but their efficiency is of concern due to intermittent nature of solar radiation and non-optimum inclination of PV panels. The PV system power potential is enhanced using reflectors installed at optimum tilt angle. In this study performance of a PV-mirror reflector system installed at respective optimum tilt angles, is evaluated for a two-year period. The average power enhancement of PV-reflector system is found to be 10e19.84% in summers and 10e13.23% in winters. A new model is developed to determine reflector optimum tilt angles and the results are validated experimentally. The reflector optimum tilt angles are determined to be 400 for summer and 150 for winter for Hamirpur location, Himachal Pradesh, India. The error in the predicted and experimental optimum tilt angles is found to be 12.5%. The PV module temperature rise due to reflector is found small so the effect on PV efficiency is not substantial for this location. The present study is of relevance for PV power plants to improve land use efficiency and to reduce the cost of energy generation for any location worldwide. Further follow up research areas are also identified.

Intelligent photovoltaic panels based on solar tracking
摘要： The transformation of solar energy into electricity using photovoltaic cells has many economic and environmental benefits. As this technology reduces dependence on non-renewable energy sources, many developed and developing countries near the equator are increasingly willing to adopt such energy generation techniques. Its tilt angle with the horizontal plane and its orientation determines the photovoltaic panel (PV) yield. Thus the solar energy obtained from traditional photovoltaic panels can be maximized by replacing them with Intelligent photovoltaic panels. The Intelligent Photovoltaic panels adjust its orientation as well as tilt angle automatically with changing sun direction to receive maximum possible solar energy on its surface. A handful of studies on the orientation of tilt angle and its optimization have been conducted to improve the yield of photovoltaic panels; however, no solution has been proposed to estimate the optimum value of the parameters based on real-time monitoring.

摘要： The solar PV power sector in Spain has been developing at a spectacular rate in recent years. The energy cost and the dependence on fossil fuels can be reduced by improving the efficiency of photovoltaic energy production The performance of a solar radiation conversion system is affected by tilt angle with the horizontal plane. Thus, a photovoltaic array needs to be tilted at the correct angle to maximize its performance. In this paper, we investigate how to determine the optimum tilt angle. This procedure is illustrated for the city of Barcelona (Spain) located at latitude 41o 22' 56'' North and longitude 2o 6'56'' East. The optimal tilt angle varies according the seasons: In Winter (December, January, February) is 56.4, in Spring (March, April, May) is 29.11? in Summer (Jun, July, August) is 13.76? and in Autumn (September, October, November) is 48.14?. Finally, the annual optimum tilt angle for our latitude is 36.87?, with this optimal slope angel, maximum monthly and annual solar radiation is calculated. So, by means of the proposed approach, the energy generation is increased in 10.54% thanks to we are able to benefit from the maximum solar radiation.

Optimum Tilt Angle and Orientation of Photovoltaic Thermal System for Application in Greater Toronto Area, Canada
摘要： We present a study conducted to obtain optimum tilt angle and orientation of a solar panel for the collection of maximum solar irradiation. The optimum tilt angle and orientation were determined using isotropic and anisotropic di?use sky radiation models (isotropic and anisotropic models). The four isotropic models giving varying optimum tilt angles in the range of 37 to 44°. On the other hand, results of the four anisotropic models were more consistent, with optimum tilt angles ranging between 46–47°. Both types of models indicated that the collector tilt should be changed four times a year to receive more solar radiation. The results also indicate that the solar panel should be installed with orientation west or east of due south with a ?atter tilt angle. A 15° change in orientation west or east of due south results in less than 1% reduction of the total solar radiation received. For a given optimum tilt angle, the e?ect of photovoltaic/thermal (PV/T) orientation west or east of due south on the outlet temperature was determined using a one-dimensional steady state heat transfer model. It was found that there is less than 1.5% decrease in outlet temperature for a PV/T panel oriented up to 15° east or west of due south from March to December. This result indicates that existing roofs with orientations angles up to 15° east or west of due south can be retro?tted with a PV/T system without changing the roof shape.

Determining Optimum Tilt Angles of Photovoltaic Panels by Using Artificial Neural Networks in Turkey
摘要： Sun is the most important energy source of the world. To make use of this energy source effectively, the sun’s angle of incidence to earth must be known. The angle, however, between rotation axis and orbital plane of the world is not constant and it changes continuously. Depending on this change, the incidence angle of sun beams also change. For purpose of increasing the light amount falling on solar panels, light beams must be adjusted according to their angles of incidence. The difference of this study from the studies in literature realized to determine the optimum tilt angle by means of mathematical methods is the determination of optimum tilt angles with artificial neural networks. In the study, not each province within boundaries of Turkey but the whole country as a system was introduced to the artificial neural network. Thanks to this, monthly optimum tilt angle of the system to be installed in any place within boundaries of Turkey was determined by the artificial neural network. The installed solar panels were adjusted according to this optimum tilt angle. Thanks to this, it was ensured to be obtained maximum output from solar panels. Mounting of the system according to an angle as predicted by artificial neural network has caused 34% increase in energy amount obtained from fixed solar panel systems. Consequently, in this study, in prediction of optimum tilt angle of fixed solar panels, in what extent the artificial neural networks are successful were observed. It was determined that correct results have been obtained in respect of both economy and utilization.
