“…This would result in reliable and accurate comparisons regarding the impact of dust accumulation-as an independent variable-on both of the PV modules. From a distinct related perspective, it is worth mentioning that a recent study has concluded experimentally that the dust accumulation density hardly has any effect on the operating temperature of a PV module [37]. The usefulness of the indoor testing configuration is that both of the irradiance and temperature-the most influencing parameters on the performance of PV modules-can be controlled, or in other words, maintained and measured at desired and well determined levels during capturing the IV characteristics of the tested PV modules.…”

This article evaluates the impact of dust accumulation on the performance of photovoltaic (PV) modules in two different locations inside Egypt, Cairo and Beni-Suef. Two identical PV modules were used for that purpose, where each module was exposed to the outdoor environment in order to collect dust naturally for a period of three weeks, each in its corresponding location. The approximate dust density on each of the two PV modules was estimated. Moreover, the electrical performance was evaluated and compared under the same indoor testing conditions. The results show a better electrical performance and less dust density for the PV module located in Cairo compared to that located in Beni-Suef. The results further provide an indication for the impact of soling in different locations within the same country through a clear and simple procedure. In addition, it paves the way for establishing a Photovoltaic Soiling Index (PVSI) in terms of a Photovoltaic Dust Coefficient, as well as a Photovoltaic Dust Interactive Map. The product of such concepts could be used by the Photovoltaic systems designers everywhere in order to estimate the impact of dust on the future performance of PV modules in small and large installations in different regions around the globe, and during different times of the year as well.

“…β: Tilt angle, is the angle between the solar panel and the horizon, as shown in Figure 8. [32]. For a surface facing to the south (azimuth angle equals zero, γ=0°), equation 11can be simplified as follows, For a horizontal surface, the tilt angle equals zero (β=0°), and equation 12can be simplified to be as equation (13).…”

The evolution of solar photovoltaic systems (PV) in the last decade has been marvellous around the world. This growing in using of PV technique hinge on the electrical load profile that required to be covered and the rate of the electricity that can be generated from the areas where the solar cells to be installed. The production of PV systems is based on the fuel which is represented by the solar radiation. In this study, an algorithm has been proposed to optimize the solar tilt angle based on MATLAB software (m-file) in order to maximize the PV generation. Monthly and annually optimal tilt angles are suggested for different case studies those are: Najaf, California and New Delhi. Also, the estimation of solar radiation for each month is calculated according to their optimal tilt angles. The obtained results indicate that the yearly gain of solar radiation from orientation solar panels is approximately 18% for Najaf city and a high gain values for winter months with very small energy gains for summery months, and so on for other case studies. This proposed algorithm is general program and can be applied for any site on the earth by changing the latitude and longitude of the desired area.

“…To achieve a maximum amount from solar energy incident on the earth must oriented the solar panel in direction which the incident angle of solar radiation has the minimum value [13] because of the value of solar incident on the panel approximated from maximum value 1000W/m2 [14] Experimentally cannot achieve the maximum amount of solar power (1000W/m2) because of many factor such as the cloud, dust, smoke, [15] which lead to reduce the amount of the solar radiation incident to the panel, as well as the sun position in the sky which cause the variation of incident angle for the radiation [16].…”

In this paper we present evaluated the performance of four small PV modules at different tilt angle and analyze the relationship of solar radiation power Production with the angle by using actual measurement data for all months of the year and in August specially. And then study the relationship between the solar radiation and output power. We installed these panels in four angles at 0°, 15°, 30°, 45°, and fixed solar panel all the month of the year and fixed in august especially to study the daily solar radiation in summer .The results indicate that the highest output power of the PV is obtain in July at the 35° tilt surface for all day's year.
