Effects of shading and blocking of solar radiation intensity through Fresnel lens onto solar cell were investigated in this work. Fresnel lens was made of polyvinyl chloride to concentrate the solar radiation onto the polycrystalline silicon solar cell with the 0.767 m x 0.670 m in size and no cooling under the solar panels. The temperature and efficiency comparisons between solar module with and without Fresnel lens were observed. The performance of the two modules overtime is assessed by monitoring the characteristic I-V and P-V curves. The maximum efficiency of the solar panels with Fresnel lens and without Fresnel lens in each hour was approximately 5-6.7% and 8.8-11.5%, respectively. This lower efficiency of PV module with Fresnel lens was a result of unsuitable distance of Fresnel lens that operated with the PV module.

In the present study, performance analyses of a solar module are made through the optimal variation of solar tilt angle, pertaining to the maximum generation of solar energy. The work has been carried out for a particular location at Tripura, in India, considering three different cases on an annual basis. An intelligent behavioural based algorithm, known as artificial bee algorithm (ABC), has been implemented for finding the optimal orientation of solar angle in analysing the performance. The result shows marginal differences are obtained in producing yearly maximum solar energy for different orientations of the PV module. It has been observed that the maximum average solar energy is obtained for the case where continuous adjustment is made by rotating the plane about the horizontal east-west axis within 20° to 30° tilt angle. The computed maximum and minimum of the monthly average efficiency is 10.9% and 8.7%, respectively. Further, a comparative study has been performed in generating average solar energy through optimal tilt angle by the implementation of Perturb & Observe method (P&O). The monthly average solar power computed by P&O method resulted better in a range of 2% to 15% in comparison to that obtained by ABC. While on the other hand, the efficiency computed by ABC algorithm was 15% to 19% better than that evaluated by P&O method for all the cases studied in the present work.

The article outlines the problem of the influence of climatic factors on the efficiency of solar panels operation. Not long ago the idea of free electricity seemed incredible. However, the development of technologies rapidly progresses, and the alternative energy captures more and more supporters every day. The popularity of solar panels is growing quite rapidly, since photovoltaic converters are an efficient source of electricity. But for more efficient operation of solar cells it is necessary to create the specific conditions, taking into account the location of the unit. There have been considered the factors of more efficient operation of the photovoltaic converters: the hash climatic conditions and the intensity of solar radiation depending on the angle of reducing the impact of the solar rays onto the solar cell surface.

Solar Radiation Intensity

The aim of this paper was to investigate the influence of solar radiation intensity, ambient temperature, wind speed and solar module temperature on the modules physical characteristics, in local climate conditions and for all seasons in Nis, Serbia. Twelve sunny days, for each month of the year, from the period September 2014 - June 2016 were selected. During each day meteorological parameters, solar module temperature and solar module output parameters were measured. The highest values of solar radiation intensity, ambient temperature and solar module temperature were measured in summer months, while the lowest values were in winter months. The maximal values of the output power were measured in summer months due to the high values of solar radiation intensity on the solar modules surface. A negative impact of high solar module temperature on the open circuit voltage, the output power, the fill factor and the efficiency was observed. In the winter months the local climatic conditions and air pollution have an adverse impact on the solar module efficiency and lead to a noticeable reduction of the efficiency.

The contribution deals with the climatic conditions in which a solar rotatable structure with flat solar panels was placed on the roof of the building in which the Department of Process Technique is located. There was designed a control system of the structure in order to achieve an increase in efficiency of solar panels. Presented are three ways of the rotatable structure positioning. During the first measurements, the data were obtained and recorded with a fixed position of the solar panels, the second measurements were carried out while the solar panels were rotating along the ecliptic without being dependent on the actual value of the solar radiation intensity, while with the third measurements the rotation was initiated depending on the intensity of the incident solar radiation on the collectors surface. The archived data obtained from individual measurements are presented in the graphs which show the advantage of solar panels rotation in terms of achieving higher temperatures of a solar fluid and a heat transfer medium of an accumulation tank.

The optimal solar radiation received on an inclined surface is always critical for energy purposes at a location or in an area. Therefore, many attempts have been made worldwide to calculate the optimum tilt angle for this purpose. The present study gives an answer about the south-oriented inclination or inclinations of solar panels in Greece for maximum efficiency. The analysis shows that an angle of 25° (and 30° in some cases) facing south is the most appropriate. To calculate this, the energy sums received on surfaces with inclination angles of 0–60° with a step of 5°, including φ° (φ being the geographical latitude) facing south at 33 locations in Greece were analyzed monthly, seasonally, and annually. The solar radiation data used in this work comes from corresponding typical meteorological years (TMYs) generated for the above locations. TMYs are used for the first time worldwide for the study of the optimum energy received by solar panels tilted south. Four new energy zones are defined to cover the whole of Greece.

One of the major environmental problem is the long-term changes in the Earth’s climate. In this study, the variation of solar radiation for Akwanga zone, Nasarawa State, Nigeria were determined. Twelve locations were carefully selected where there is no sunshine and wind obstruction. Three 12V, 5W Solar panels (poly) were used and a three-hour daily measurement interval (12.00 pm to 3.00 pm) was made using the Secondary Standard Pyranometer placed on the top of the panels. Angstrom-Prescott Regression Equation was used to estimate the output. The continuity in the assembled system was measured using an Avometer. The result revealed that the highest monthly average daily global solar radiation was observed in the month of April (25.2 MJ/m2) followed by June (22.94 MJ/m2), and march (22.42 MJ/m2), while the lowest was observed in the month of August (12.04 MJ/m2) followed by July (13.57 MJ/m2), and September (14.26 MJ/m2) in the locations selected. The solar radiation intensity was found to range from 156.44 W/m2 to 293.84 W/m2 with the mean value of 220.04 W/m2. The highest total global solar radiation value of 25.2MJ/m2 was observed in April while the lowest value of 12.04 MJ/m2 was observed in October. The extraterrestrial solar radiation were found to range from 16.72 MJ/m2 in March to 29.90 MJ/m2 in April with average value of 22.89MJ/m2. The atmospheric transmission coefficient over the year is found to range from 0.5 in July and October to 1.3 in June and October. The investigation reveal that there is bright sun shine in the study area which confirms high atmospheric transmission coefficient or clearness index throughout the year in this study.
