The Basics of Solar Energy: How Solar Energy Panels Work

Solar energy is a sustainable and non-polluting source of energy that has actually been used for centuries. Nevertheless, it wasn’t until recently that the technology to harness solar energy effectively and cost effectively appeared. Solar power is among the most abundant renewable resources on this planet. It’s discovered in the sunlight and heat from the sun, along with 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 energy straight. There are a number of methods to utilize solar energy, each with its own benefits and drawbacks. The 3 primary approaches of utilizing solar energy are photovoltaic panels, concentrated solar energy systems and thermal collectors. Let’s take a closer take a look at how solar panel technology works …

What are Photovoltaic Panels?

Photovoltaic panels, also referred to as photovoltaic panels, are the most cost-efficient and widely used technique of utilizing solar energy. These panels are made from semi-conductive materials that absorb sunlight and convert it into electricity. Panels are installed on rooftops or installed on the ground, and wired together to form an “array.” The amount of energy produced depends upon the quantity of sunlight that strikes the panels, their performance, size of the setup, and the climate. Solar power is considered a renewable resource source due to the fact that the sun will constantly be around, and the amount 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

Concentrated solar energy, or CSP, utilizes mirrors to focus sunlight on solar collectors. The heat from the collectors is used to create steam to drive turbines that produce electrical power. Just like photovoltaic panels, the sun’s intensity and readily available surface area are crucial consider the amount of energy that can be produced. CSP plants are most efficient in areas where sunshine is plentiful and temperatures are high. The innovation is typically used to create electricity for big commercial operations, such as mining and water desalination. CSP is a reasonably brand-new type of solar energy that has greater getting capacity than photovoltaic systems.

Thermal Collectors

Another kind of solar energy is thermal collectors, which utilize the sun’s heat to drive a process that creates electrical energy. Thermal collectors are used in solar water heater, and in solar thermal power plants, likewise known as concentrated solar energy (CSP) plants. Solar thermal energy is another technique of harnessing solar power, separate from photovoltaic systems. However like photovoltaic systems, solar thermal collectors utilize sunshine to produce energy. Solar thermal collectors can be installed on rooftops or utilized at bigger scales to create electrical power. Large-scale solar thermal plant operations, however, are uncommon in the U.S.

How Solar Panels Work

Photovoltaic panel have photovoltaic cells that collect the sun’s energy and change it into electrical energy. Each solar battery is made up of two 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 amount of energy a solar panel can produce depends upon a variety of factors, including: The quantity of sunshine available in the area The number of hours of sunshine a day The effectiveness of the photovoltaic panels The voltage of the system Solar power is a sustainable source of energy, however one that depends on sunlight. If there is no sunshine, the panels do not produce power even though they do not contaminate or contribute to environment change.

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 nonrenewable fuel sources do. There is likewise no threat 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 inside 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 implies that you do not have to fret about buying or saving fuel, or any associated costs.

Use of existing facilities – 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 connect your solar panels to the grid. This enables you to offer your excess energy to your regional energy company.

No water use – Hydropower is among the largest contributors to renewable energy sources, but it needs a great deal of water. Solar panels do not need any water, which is particularly essential in deserts.
No land use – Unlike wind turbines, photovoltaic panels do not need any land for installation.
No wildlife impact – Solar panels do not kill birds and other wildlife like other energy sources do.

Cons of Using Solar Energy

Seasonal irregularity – Solar energy depends on the quantity of sunshine offered in a region at a provided time. In general, the amount of sunlight is greater in the summer season than in the winter season. However, the amount of sunshine received in the winter is frequently enough to meet the energy needs of a family.
Adequate sunlight – Solar panels need to be positioned in a manner that they can get direct sunlight, at least six hours a day. If they don’t get enough sunlight, they can’t produce electrical energy.
Fewer hours of sunshine in winter season – Because sunlight is lower in winter season, it takes longer for solar panels to generate the same amount of energy as in summer.
Atmospheric conditions – Clouds can block the sun and reduce the quantity of energy reaching photovoltaic panels.

Conclusion

Solar power has been around for centuries, however just in the past couple of years has technology advanced to the point where it can be utilized efficiently. The three main methods of using solar power are photovoltaic panels, concentrated solar energy systems and thermal collectors. Solar panels are the most cost-effective and commonly utilized technique of harnessing solar power, while CSP utilizes mirrors to focus sunlight on collectors.
