Photovoltaic Systems. The function of a photovoltaic system is to generate electricity from sunlight, either in the form of DC or AC, to meet the demand of electrical loads.
Concentrated PV (CPV) systems concentrate sunlight on solar cells, greatly increasing the efficiency of the cells. The PV cells in a CPV system are built into concentrating collectors that use a lens or mirrors to focus the sunlight onto the cells. CPV systems must track the sun to keep the light focused on the PV cells. The primary advantages of CPV systems
Main components of a solar power system. Photovoltaic cells: They are able to capture direct sunlight as "photons".They also comprise sandwiched layers of semi-conductor particles, like phosphorous and boron. When a sunlight particle hits such a photovoltaic cell through a photon, it automatically triggers the "electrons" contained
