Solar energy is a sustainable and non-polluting source of energy that has been utilized for centuries. It wasn’t till just recently that the innovation to harness solar power efficiently and cost effectively ended up being readily available. Solar energy is one of the most abundant renewable resources on this planet. It’s found in the sunshine and heat from the sun, in addition to from other sources such as geothermal, hydropower, wind, biomass, and even ocean waves. Solar power can be converted into heat or light, or be utilized to create electrical power directly. There are numerous methods to utilize solar power, each with its own benefits and disadvantages. The three main techniques of utilizing solar energy are photovoltaic panels, concentrated solar power systems and thermal collectors. Let’s take a better look at how solar panel technology works …
What are Photovoltaic Panels?
Photovoltaic panels, also called solar panels, are the most affordable and widely utilized technique of utilizing solar power. These panels are made from semi-conductive materials that absorb sunlight and transform it into electricity. Panels are mounted on rooftops or installed on the ground, and wired together to form an “array.” The quantity of energy generated depends on the quantity of sunlight that hits the panels, their performance, size of the installation, and the environment. Solar power is thought about a renewable energy source due to the fact that the sun will always be around, and the quantity of energy it produces is constant. Today, there are a range of photovoltaic panel models available such as crystalline silicon, thin film, and cadmium telluride.
Concentrated Solar Power
Focused solar power, or CSP, uses mirrors to focus sunshine on solar collectors. The heat from the collectors is used to generate steam to drive turbines that generate electrical power. Just like photovoltaic panels, the sun’s strength and available surface area are critical factors in 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 innovation is frequently utilized to generate electricity for large industrial operations, such as mining and water desalination. CSP is a relatively new kind of solar power that has higher generating capability than photovoltaic systems.
Thermal Collectors
Another type of solar energy is thermal collectors, which use the sun’s heat to drive a process that creates electrical power. Thermal collectors are used in solar water heating unit, and in solar thermal power plants, also known as concentrated solar energy (CSP) plants. Solar thermal energy is another approach of utilizing solar energy, separate from photovoltaic systems. Like photovoltaic systems, solar thermal collectors utilize sunshine to generate energy. Solar thermal collectors can be installed on rooftops or utilized at bigger scales to create electricity. Massive solar thermal plant operations, however, are unusual in the U.S.
How Solar Panels Work
Solar panels have solar batteries that collect the sun’s energy and transform it into electricity. Each photovoltaic cell is comprised of 2 layers: an electron-rich layer that is favorably charged, and a negatively charged electron-deficient layer. When light hits the top 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 home appliances, charge batteries, or link to the electrical power grid. The amount of energy a solar panel can produce depends on a variety of aspects, including: The quantity of sunshine available in the area The variety of hours of sunshine a day The performance of the photovoltaic panels The voltage of the system Solar power is a sustainable source of energy, however one that is dependent on sunlight. If there is no sunshine, the panels do not produce power even though they do not contaminate or contribute to climate change.
Pros of Using Solar Energy
Sustainability – Solar energy is derived from a naturally occurring resource. It’s a renewable resource source so it does not go out like nonrenewable fuel sources do. There is likewise no risk of exhaustion like there is with natural deposits like water and minerals.
No greenhouse gases – Like other forms of renewable energy like hydropower, geothermal and wind, solar power does not produce any greenhouse gases.
No pollution – When photovoltaic panels are used inside your home or in metropolitan settings, they can produce energy without producing any pollution.
No fuel costs – Solar panels are powered by sunlight, not by a fuel. This indicates that you don’t have to fret about buying or storing fuel, or any associated costs.
Use of existing infrastructure – You can utilize the existing electrical wiring in your home to power your solar panel system.
Grid-tied systems – Unlike other alternative energy sources, you can link your solar panels to the grid. This allows you to offer your excess energy to your local utility company.
No water use – Hydropower is among the biggest contributors to renewable resource sources, however it needs a lot of water. Solar panels don’t require any water, which is especially important in arid regions.
No land use – Unlike wind turbines, solar panels don’t require any land for setup.
No wildlife effect – Solar panels don’t eliminate birds and other wildlife like other energy sources do.
Cons of Using Solar Energy
Seasonal irregularity – Solar energy depends on the quantity of sunlight offered in a area at a offered time. In general, the quantity of sunshine is greater in the summer season than in the winter season. However, the amount of sunlight received in the winter is often adequate to fulfill the energy needs of a household.
Adequate sunshine – Solar panels require to be located in such a way that they can receive direct sunlight, a minimum of 6 hours a day. If they don’t get enough sunshine, they can’t produce electrical power.
Less hours of sunlight in winter – Because sunshine is lower in winter season, it takes longer for photovoltaic panels to generate the same amount of energy as in summer season.
Atmospheric conditions – Clouds can block the sun and decrease the amount of energy reaching solar panels.
Conclusion
Solar power has been around for centuries, but just in the past couple of years has innovation advanced to the point where it can be utilized effectively. The three main techniques of making use of solar energy are photovoltaic panels, concentrated solar energy systems and thermal collectors. Photovoltaic panel are the most cost-effective and commonly used technique of utilizing solar power, while CSP utilizes mirrors to focus sunlight on collectors.
