Concentrated photovoltaic in Thanjavur Sri Saravanas Agencies Concentrated Photovoltaic (CPV) is a solar energy technology that generates electricity by using optical elements, such as lenses or curved mirrors, to focus a large amount of sunlight onto a very small, highly efficient solar cell. Unlike conventional 'flat-plate' solar panels that use large silicon cells spread over a wide area, CPV systems concentrate the sunlight, allowing them to use much smaller (and often more expensive) solar cells. This approach aims to reduce the amount of expensive semiconductor material needed while maximizing energy output
