Solar Energy Applications Wikipedia

The increasing demand for sustainable energy sources and environmental concerns have driven the demand for solar energy applications in recent years. Solar power is now a viable choice for homes and businesses with the development of clean, affordable energy. This article will explore the different ways in which solar energy can be used and how it is beneficial to human life.


Solar energy can be converted into electricity using photovoltaic (PV) cells. These cells are generally made of silicon and can be used to generate electricity from sunlight directly. The amount of electricity generated is dependant on the size of the solar array and its exposure to the sun’s rays. The higher the photovoltaic cell efficiency, the more electricity that can be generated from the same amount of sunlight. The energy conversion process is very efficient with only 4% of the input energy being lost as thermal energy during generation.

This form of energy is clean and renewable, and its price is gradually coming down. Furthermore, the equipment and installation needed to generate electricity using solar energy are relatively simple and can be done by individuals with little to no engineering or technical knowledge. Due to these factors, it is likely that the number of homes and businesses using solar energy as a power source will continue to increase in the near future.


An alternative way of using solar energy is to collect it directly and transfer it into useful forms such as heat or hot water. It is generally more efficient to use thermal energy for heating than it is to generate electricity and then use an intermediate storage device to heat water. The efficiency of thermal solar power systems is between 30% and 60%, which is comparable to the efficiency of traditional heating systems (such as ones using oil or gas). The equipment and installation for these types of power systems are also simpler than those of PV-generated electricity, and they do not require specialized engineering knowledge or professional installation services.

Due to these benefits, it is obvious that homes and businesses will continue to use solar energy for space and water heating as economic, environmental, and sustainable energy standards continue to rise.

Refrigeration And Air-Conditioning

Even though heat is most commonly associated with energy and refrigerators are most commonly used as an intermediate storage device for thermal energy, they can also be used to generate electricity through the use of a photovoltaic cell. In this case, the temperature of the refrigerant is kept constant, and so is that of the air inside the refrigerator. This creates a favorable environment for the growth of bacteria and fungus, which are harmful to humans and animals. This risk can be greatly reduced by simply buying a refrigerator with a built-in photovoltaic cell or installing one afterward.

Similarly, air conditioners can be used to effectively generate electricity, and so are refrigerators with built-in photovoltaic cells. This is because the temperature of the air within the refrigerator can be controlled through the use of an electric fan and coil, which cools or warms the air as required. This process of cooling or heating the air can be effectively repeated many times over through the use of a cycle, allowing for the manufacture of electricity on a continuous basis. The amount of electricity generated by a refrigerated photovoltaic system is relatively stable; however, this varies based on the weather and time of day, with the amount ranging from 300 to 3,000 watts per day. This is a significant amount of power and makes refrigerated photovoltaic systems a viable choice for those looking for a renewable energy source with few environmental risks.

These types of energy are often associated with farms and food processing plants due to the fact that they help keep the product fresh during transit. Furthermore, farms using these types of energy are able to avoid wasting much of the electricity they generate, as they can sell any excess energy produced back to the grid. This is beneficial to both the environment and the consumer, as it keeps the power stations from having to find new places to plug into and reduces the load on the power grid, lowering the rate of electricity theft and blackouts while also helping to reduce greenhouse gas emissions.

Industrial Applications

While residential consumers are beginning to adopt solar energy for various applications, large-scale industrial users have been early adopters, utilizing solar energy to power whole factories and generating significant amounts of electricity. This electricity is then distributed where needed using grid-connected solar photovoltaic systems.

For example, solar energy is used to power a factory that makes surgical needles. Due to the fact that so few people need to purchase these needles, the factory is able to generate a significant amount of revenue. In addition, the cost of the energy used to run the factory is quite low, as the photovoltaic module and battery system used are quite efficient and inexpensive. This enables cheaper, more economical production of goods and benefits both the consumer and the environment by reducing energy costs and the amount of harmful waste produced by industry.

Another example is a large-scale factory that makes car parts and assemblies. Here, too, solar energy is used to generate electricity, with the parts and assemblies being heated as they are moved through the factory over large metal plates. This is to ensure that the plastic parts don’t melt during transit. Due to the nature of this process, the factory’s energy needs are quite high, with up to 7,500 watts per day being generated. This is more than enough to power the entire factory.

The use of solar energy in industry helps reduce the amount of carbon dioxide produced as a byproduct of traditional power generation, as the gas is less harmful to the environment when it is cleanly produced by solar power systems. In addition, due to the increasing cost of fossil fuels and the decreasing cost of solar energy, it is likely that the price of this energy will continue to decline, further reducing the cost of industrial-level electricity generation.

Trash And Recycle

Finally, we come to waste disposal and recycling, two important processes that contribute greatly to sustainable living. Several studies have shown that if you can reduce or eliminate your trash production, you can effectively reduce your carbon footprint and become more eco-friendly. This is why so many eco-friendly products are now being designed and manufactured with a “zero-waste” mindset, with packaging becoming more and more innovative and creative to minimize the amount of trashed during production.

While the generation of electricity using solar energy as a source is usually seen as beneficial for human life, it can also contribute to both our trash production and carbon footprint. This is because solar-generated electricity is generally used to power electronics and appliances on a household or business level, with all the associated wire and electrical cables being replaced with smart power strips and surge protectors. When these appliances and electronics are eventually discarded, they usually end up in a small landfill until they decompose naturally, releasing toxic gases that harm us as well as the environment. This decomposition process of electronic and electrical waste generally takes several years and involves a lot of soil and water pollution.

To avoid this, it is important to understand that when new appliances and electronics are purchased, they should be energy efficient and have small carbon footprints, with the manufacturer considering the environmental impact during the design stage. Furthermore, since so many people are now realizing the benefits of a sustainable lifestyle, new appliances and electronics that are eco-friendly and reduce the amount of energy used are more likely to be purchased and recycled, helping to save the environment and reduce our dependence on fossil fuels.
