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 thermally 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.
