Solar power plants use the energy from the sun to convert it into electricity, which can be used to power homes, businesses, and even entire cities. Here we will explore the basics of solar power plants, their benefits, and how they work.
They come in a variety of types, with each using discretely different techniques to harness the power of the sun. In the following article, we’ll take a quick look at the different types of solar power plants that harness energy from the Sun to produce electricity.
Photovoltaic power plants use large areas of photovoltaic cells, known as PV or solar cells, to convert sunlight into usable electricity. These cells are usually made from silicon alloys and are the technology most people have become familiar with – chances are you may even have one on your roof. The panels themselves come in various forms:
1. Crystalline solar panels: As the name suggests, these panels are made from crystalline silicon. They can be either monocrystalline or polycrystalline (also called multi-crystalline). As a rule of thumb, monocrystalline versions are more efficient (about 20% or above) but more expensive than their alternatives (which tend to be 15-17% efficient), but advancements are closing the gap between them over time.
2. Thin-film solar panels consist of films that absorb light in different parts of the EM spectrum. They tend to be made from amorphous silicon (a-Si), cadmium telluride (CdTe), cadmium sulfide (CdS), and copper indium (gallium) diselenide. This panel type is ideal for applications as flexible films over existing surfaces or for integration within building materials like roofing tiles.
These solar power panels generate electricity directly fed into the national grid or stored in batteries. mPower plants using these types of panels tend to have the following basic components:
Solar PV power plants work in the same manner as smaller domestic-scale PV panels. As we have seen, most solar PV panels are made from semiconductor materials, usually some form of silicon. When photons from sunlight hit the semiconductor material, free electrons are generated, which can then flow through the material to produce a direct electrical current.
This is known as the photoelectric effect. The DC must then be converted to alternating current (AC) using an inverter before it can be directly used or fed into the electrical grid. PV panels are distinct from other solar power plants as they use the photo effect directly without needing other processes or devices. For example, they do not use a liquid heat-carrying agent, like water, as in solar thermal plants. PV panels do not concentrate energy; they convert photons into electricity transmitted somewhere else.
Solar thermal power plants, on the other hand, focus on or collect sunlight in such a manner as to generate steam to feed a turbine and generate electricity. Solar thermal power plants can also be subdivided into a further three distinct types:
The most common forms of a solar power plant are characterized by their use of fields of either linear collectors, parabolic trough collectors, or solar dishes. These facilities have a large ‘field’ of parallel rows of solar collectors. They tend to consist of three discrete types of systems:
Parabolic troughs use parabola-shaped reflectors that are able to focus between 30 and 100 times normal sunlight levels onto the collector. The method is used to heat a fluid, which is then collected at a central location to generate high-pressure, superheated steam.
These systems tilt to track the sun throughout the day. The longest-operating solar thermal plant in the world, the Solar Energy Generating Sytems (SEGS) in the Mojave Desert, California, is one of these power plants. The first plant, SEGS 1, was built in 1984.
Linear concentrating systems, sometimes called Fresnel reflectors, also consist of large ‘fields’ of sun-tracking mirrors that tend to be aligned in a north-south orientation to maximize sunlight capture. This setup allows the banks of mirrors to track the sun from east to west throughout the day.
Much like their parabolic mirror cousins, linear concentrating systems collect solar energy using long, rectangular, U-shaped mirrors. Unlike parabolic systems, however, linear Fresnel reflector systems place the receiver tube above the mirrors to allow the mirrors greater mobility in tracking the sun.
