Abstract
The current concerns of energy shortage and global warming have brought the development of strategies to utilize renewable energy resources at the forefront of public interest. Solar power is one of renewable energy's most promising sources. Concentrated photovoltaics can significantly improve a photovoltaic (PV) system's electricity production. This paper presents a novel approach of a CPV unit with a dynamic lens structure. Design and Implementation of both electrical and mechanical design in order to move the lens to achieve a better voltage output. Experiments had been carried out and measurements were taken according to the light source which was the sun in one case and the artificial light in the other. Based on the experimental results the effect of the dynamic lens was studied and compared to the fixed lens. The results showed that the dynamic lens CPV model was more effective and efficient than the fixed one.
