“…The performance evaluation of photovoltaic cell under scattered sunlight carried out by Zakzouk et al; showed the photo-generated current increases linearly with cell temperature at a rate of 5Ma/°C for a concentration ratio of 45. The result also imply that the rate depends on the concentration ratio [5] . The results also showed that the optimum value of the incident solar intensity depends on the cell temperature, and it increases with increasing cell temperature.…”

The world demand for alternative energy source has increased with the consumption of energy increasing tenfold in the past five decades. Solar power generation is one such alternative, and Concentrated Photovoltaic Technology (CPV) is one of the two main technologies used for producing electricity from Concentrated Solar Power (CSP). Meteorological parameters such as solar irradiance and cell temperature when the sunlight is concentrated on the CPV module influence the efficiency of the CPV power generation systems. Additionally, the output power of a CPV plant must be measured and monitored to improve the condition of plant, again in terms of efficiency and reliability. Firstly, in this paper, the significance of the meteorological parameters and the CPV system parameters are discussed. This is followed by a description of proposed multichannel data acquisition and logger for CPV technology. Experimental results have proven a good level of accuracy of the proposed system in terms of the acquired meteorological parameters and CPV system parameters.

“…PV cells provide 0.1% of the global electricity generation and are projected to provide 5% of global electricity consumption in 2030, rising up to 11% in 2050 [2]. Many researches showed that the cost of the energy produced by traditional flat PV panels may be reduced by PV concentrators [3][4][5]. Since semiconductor material is the most expensive part of the PV system and PV cells can theoretically produce more energy if exposed to higher sunlight fluxes, PV concentrators are based on focusing a large amount of solar radiation on a small surface of high-efficiency PV cells.…”

Many researches showed that the cost of the energy produced by photovoltaic (PV) concentrators is strongly reduced with respect to flat panels, especially in those countries that have a high solar irradiation. The cost drop comes from the reduction of the expensive high-efficiency photovoltaic surface through the use of optical concentrators of the solar radiation. In this paper, an experimental innovative PV low-concentration system is analysed. Numerical simulations were performed to determine the possible reasons of energy losses in the prototype, primarily due to geometrical factors. In particular, the effect of the shadows produced from the mirrors on the prototype performances was analysed: shadows are often neglected in the design phase of such systems. The study demonstrates that shadows may affect the performances of a hypothetical optimized PV low-concentration system up to 15%. Finally, an economical evaluation was carried out comparing the proposed optimized system to a traditional flat PV panel.
