As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built. Solar PV is rapidly becoming an inexpensive, low-carbon technology to harness renewable energy from the Sun.
Solar power is the use of the sunâs energy either directly as thermal energy (heat) or through the use of photovoltaic cells in solar panels and transparent photovoltaic glass to generate electricity.Standard photovoltaic solar panels are the most efficient application of photovoltaics.oncentrated solar power uses multiple lenses or reflectors to collect more of the sunâs thermal energy. Thermal energy collected through the day is typically applied to oil or molten salts that retain heat to boil water for steam turbine generators throughout the night.
