How Does Solar Power Create Electricity? Solar power generates electricity by using either solar thermal systems that convert sunlight into heat to produce steam that drives a generator, or photovoltaic systems, which transform sunlight into electricity through the photovoltaic effect.
There are two main ways of generating energy from the sun. Photovoltaic (PV) and concentrating solar thermal (CST), also known as concentrating solar power (CSP) technologies. PV converts sunlight directly into electricity.
A solar thermal system generates electricity indirectly by capturing the heat of the sun to produce steam, which runs a turbine that produces electricity. A solar photovoltaic system produces electricity directly from the sun’s light through a series of physical and chemical reactions known as the photovoltaic effect.
The way in which most power plants generate electricity is with turbines. In a turbine, a fluid such as steam is driven by, say, the heat from combustion, nuclear energy, or solar heat to spin the rotor shaft of a generator, which converts the kinetic energy of the fluid to electricity.
Yes, it can – solar power only requires some level of daylight in order to harness the sun’s energy. That said, the rate at which solar panels generate electricity does vary depending on the amount of direct sunlight and the quality, size, number and location of panels in use.
The most common type of solar thermal power plants, including those plants in California's Mojave Desert, use a parabolic trough design to collect the sun's radiation. These collectors are known as linear concentrator systems, and the largest are able to generate 80 megawatts of electricity [source: U.S. Department of Energy].
