Concentrating Photovoltaic Solar Panel Technology

Based on the principal that a solar cell receiving more light energy will produce more electricity, concentrating photovoltaic solar panels simply involve a method ( usually using a lens or mirrors) to concentrate more sunlight onto a photovoltaic cell.
As fewer cells are then required for the same area of panel (or light capturing area) it may then become economical to use a highly efficient multi-junction cell.

Potentially, this type of panel has the following advantages:

There are however drawbacks:

Although research has continued on concentrating photovoltaics for many years, they have not made their mark on the industry, and where they have been used, it has been in large scale projects.
CPV panels that have been produced have come in "various shapes and sizes" with no obvious design leading the field.
