Solar energy is a sustainable and non-polluting source of energy that has been used for centuries. It wasn’t until just recently that the technology to harness solar power efficiently and economically ended up being offered. Solar power is among the most plentiful renewable resources on this world. It’s found in the sunshine and heat from the sun, as well as from other sources such as geothermal, hydropower, wind, biomass, and even ocean waves. Solar energy can be converted into heat or light, or be used to generate electrical power directly. There are a number of methods to use solar energy, each with its own benefits and downsides. The three primary methods of using solar energy are photovoltaic panels, concentrated solar power systems and thermal collectors. Let’s take a closer take a look at how solar panel innovation works …
What are Photovoltaic Panels?
Photovoltaic panels, also referred to as solar panels, are the most economical and extensively utilized technique of utilizing solar power. These panels are made from semi-conductive materials that take in sunshine and convert it into electrical energy. Panels are installed on roofs or set up on the ground, and wired together to form an “array.” The quantity of energy created depends upon the quantity of sunlight that strikes the panels, their efficiency, size of the installation, and the environment. Solar energy is thought about a renewable energy source because the sun will always be around, and the quantity of energy it produces is constant. Today, there are a range of photovoltaic panel designs available such as crystalline silicon, thin film, and cadmium telluride.
Concentrated Solar Power
Focused solar energy, or CSP, uses mirrors to focus sunlight on solar collectors. The heat from the collectors is used to create steam to drive turbines that create electricity. Just like photovoltaic panels, the sun’s strength and readily available surface area are vital consider the quantity of energy that can be produced. CSP plants are most efficient in locations where sunlight is plentiful and temperature levels are high. The technology is often utilized to create electricity for large commercial operations, such as mining and water desalination. CSP is a relatively new type of solar power that has greater generating capacity than photovoltaic systems.
Thermal Collectors
Another type of solar power is thermal collectors, which use the sun’s heat to drive a process that generates electrical power. Thermal collectors are used in solar water heater, and in solar thermal power plants, also known as concentrated solar power (CSP) plants. Solar thermal energy is another technique of utilizing solar energy, different from photovoltaic systems. Like photovoltaic systems, solar thermal collectors utilize sunlight to generate energy. Solar thermal collectors can be installed on roofs or used at larger scales to produce electrical energy. Massive solar thermal plant operations, nevertheless, are unusual in the U.S.
How Solar Panels Work
Solar panels have photovoltaic cells that collect the sun’s energy and change it into electrical power. Each solar battery is made up of 2 layers: an electron-rich layer that is positively charged, and a negatively charged electron-deficient layer. When light hits the leading layer, it knocks loose electrons from the bottom layer. As the electrons move from one layer to the other, they produce a current, which can then be used to power appliances, charge batteries, or link to the electrical power grid. The quantity of energy a solar panel can produce depends on a variety of elements, consisting of: The amount of sunshine available in the area The variety of hours of sunlight a day The effectiveness of the solar panels The voltage of the system Solar power is a sustainable source of energy, but one that depends on sunshine. If there is no sunlight, the panels do not produce power even though they do not contaminate or add to climate modification.
Pros of Using Solar Energy
Sustainability – Solar energy is derived from a naturally occurring resource. It’s a renewable energy source so it does not run out like fossil fuels do. There is also no risk of exhaustion like there is with natural deposits like water and minerals.
No greenhouse gases – Like other kinds of renewable resource like hydropower, geothermal and wind, solar power does not produce any greenhouse gases.
No pollution – When photovoltaic panels are utilized indoors or in urban settings, they can produce energy without producing any pollution.
No fuel costs – Solar panels are powered by sunshine, not by a fuel. This means that you do not need to stress over buying or saving fuel, or any associated expenses.
Use of existing infrastructure – You can utilize the existing electrical circuitry in your house to power your photovoltaic panel system.
Grid-tied systems – Unlike other alternative energy sources, you can link your photovoltaic panels to the grid. This permits you to offer your excess energy to your local utility company.
No water usage – Hydropower is among the largest factors to renewable energy sources, however it needs a lot of water. Photovoltaic panel do not need any water, which is especially crucial in arid regions.
No land usage – Unlike wind turbines, solar panels don’t need any land for setup.
No wildlife impact – Solar panels don’t kill birds and other wildlife like other energy sources do.
Cons of Using Solar Energy
Seasonal variability – Solar energy is dependent on the amount of sunshine offered in a area at a provided time. In general, the quantity of sunlight is greater in the summer season than in the winter season. The amount of sunlight received in the winter is often sufficient to fulfill the energy needs of a family.
Adequate sunlight – Solar panels need to be situated in a manner that they can get direct sunshine, a minimum of six hours a day. If they do not get enough sunshine, they can’t create electricity.
Fewer hours of sunlight in winter – Because sunshine is lower in winter, it takes longer for photovoltaic panels to generate the exact same amount of energy as in summertime.
Atmospheric conditions – Clouds can block the sun and decrease the amount of energy reaching photovoltaic panels.
Conclusion
Solar energy has actually been around for centuries, however just in the past couple of decades has technology advanced to the point where it can be made use of successfully. The 3 main techniques of utilizing solar power are photovoltaic panels, concentrated solar power systems and thermal collectors. Photovoltaic panel are the most affordable and widely utilized approach of harnessing solar power, while CSP utilizes mirrors to focus sunlight on collectors.
