Benefits of Photovoltaic Technology
The amount sunlight reaching the Earth's surface is almost 6,000 times more than the average electrical power consumed by people. Solar power is pollution-free during use. Production end-wastes and emissions are manageable using existing pollution controls. End-of-use recycling technologies are under development.
PV installations can operate for many years with little maintenance or intervention after their initial set-up, so after the initial capital cost of building any solar power plant, operating costs are extremely low compared to existing power technologies. Solar electric generation is economically superior where grid connection or fuel transport is difficult ,costly or impossible. Long-standing examples include satellites, island communities, remote locations and ocean vessels. When grid-connected,solar electric generation replaces some or all of the highest-cost electricity used during times of peak demand in most climatic regions it can reduce grid loading, and can eliminate the need for local battery power to provide for use in times of darkness.
