Concentrating Photovoltaic (CPV) Systems and Applications

Summary

Using an optical assembly, concentrating photovoltaic (CPV) systems focus light onto photovoltaic (PV) cells. CPV is “a long range option of vital importance to the global energy security.” Cost analyses show that it most definitely has the potential to emerge as the PV approach with the lowest possible cost in large installations. There is sufficient proof that viable products can be developed and run, as evidenced by the interest displayed at both ends of the concentration scale. Concentrator design offers a wide range of options, which has led to the emergence of numerous distinct product styles. There are many mechanical styles of tracking systems. Degree of concentration will primarily dictate the selection of single‐ or double‐axis tracking. CPV systems are particularly suited for deployment in areas with high solar irradiance, where they can generate significant power while using less land compared to traditional PV systems.
