8 Benefits Of Using Solar Power

Solar energy is obtained from solar radiation and it can be converted into electricity or heat. Solar energy is a renewable resource that is available in nature and is free for all to use. 

Thanks to advancements in technology, we can now harness even more solar energy into a constant source of electricity available to us. Here are 8 benefits of using this renewable solar power.

1. Reduce the impact on the environment

Solar power has very little negative impact on the environment compared to any other energy source. It does not create greenhouse gases, does not pollute water, has no impact on the surrounding environment. It also requires very little water to maintain, such as nuclear power plants, which require 20 times more water. Solar power generation does not make any noise, which is a great benefit when installing solar power projects in urban areas.

2. Reduce electricity bills

Generating your own electricity means you will use less electricity from the supplier. This will instantly translate into savings on your energy bills. Alternatively, you can also make money by selling the unused electricity, which you generated, back to the grid. The more energy you produce, the less electricity you will need from the supplier, which will increase your self-reliance when producing breakdowns.

3. Use solar electricity during peak hours

Energy demand tends to be higher during the peak time frame at 09:30 – 11:30 and evening at 17:00 – 20:00 from Monday to Saturday. . With the additional solar input, the prices within those timeframes can be reduced. To save electricity effectively, especially during hot weather, you should use electricity to operate properly electrical equipment, especially cooling equipment.

4. Solar electricity is applied everywhere

As long as there is sunlight, solar energy can be deployed anywhere. This is especially useful for remote areas without access to any other power source. There are a large number of people around the world who have no electricity. Independent solar systems can be deployed in those areas and improve the lives of millions. Furthermore, solar energy is also used to power spacecraft and boats.

5. Roof cooling and protection

Solar power system built on the roofs of households, factories, resorts … is open and concentrated in sunlight. Installing solar power will help cool your home, reduce the natural impact on the home’s infrastructure, but also create electricity for your living and production activities.

6. Less electricity loss during long distance transportation

Some of the energy, about 3-5%, is lost during transportation and distribution. The longer the distance between the production point and the supply point, the more energy is lost. Those losses may seem insignificant, but they can affect installation performance in areas with high population density. Having solar panels on the roof or in the yard significantly reduces this distance, thereby increasing the efficiency of the electrical system.

7. Improved grid security

The grid is less vulnerable to a power outage if more power plants are spread out. A network with high penetration of solar energy has thousands of energy production centers spread out. This improves the security of the grid in the event of an overload, natural disaster or caused by man.

8. Create jobs

Most of the cost associated with the solar energy system comes from the installation of the panels. This contributes to local job creation. Using the solar system boosts the economy and positively affects the local community.

Other applications from solar energy

Create water heaters using heat from the sun for use in living, swimming pools, …

Solar heating system is applied in construction, using monolithic materials such as stone, cement, water, …

Water treatment systems use solar heat and solar electricity to desalinate or disinfect

Solar cookers, people also use the technique of converging sunlight to create heat for cooking, typically industrial kitchens in India are serving up to 35,000 meals per day.

Solar electric vehicle

Countries around the world have developed various types of solar-powered vehicles such as cars, planes, ships, balloons. In Australia, they hold an annual race called the “World Sun Challenge” for universities and businesses to compete on long distances of 3,021km, the most recent winners’ speed up. to 90.87 km/h.

Solar power storage

Since solar power generating systems only generate electricity directly in daylight conditions with good lighting, storing electricity or maintaining solar power generation for service at night is a problem. important issues to deal with.

To regulate the temperature in the home, construction engineers design monolithic systems to store the sun’s thermal energy to warm or cool the home.

For the operation of CSP plants (centralized solar power plants), use molten salt stored in storage tanks to keep the plant running.

With photovoltaic battery systems to generate solar power, the most common form is using rechargeable battery systems for complete storage (for independent solar power systems ) or excess electricity. (for grid-connected solar power systems ).

The development of solar power

With the development history of photovoltaic batteries over half a century, the technology and efficiency of solar power systems have increased significantly, major manufacturers in the world are still constantly researching to improve the performance of solar batteries. Manufacturing standards and raw materials are also being raised to meet health and environmental requirements.

Great benefits from solar power

Solar power is the source of electricity converted from sunlight energy into electricity, so first we have an infinite resource to exploit.

Economic significance of solar power

The supply is endless, the cost of producing solar cells is decreasing, the output of electricity is increasing over time, contributing to reducing the cost of electricity consumption.

Energy security

Future solar power could replace other forms of electricity generation from burning fossil fuels as well as restrict hydropower changing ecosystems.

Environmental benefits of solar power

Solar power is recognized as a green, clean and environmentally friendly source of energy, solar cell recycling technology has also gradually improved, according to 2014 statistics,  the average CO2 emissions of solar power is 41g/kWh compared with coal power is 820g/kWh and oil and gas is 490g/kWh

In addition, solar power is widely used in human life from daily life to production, capable of deploying on a very diverse scale and suitable for all subjects.

What is solar power and the role of solar energy? (Part 1)

Solar power is created in two popular ways in the world today: using solar panels and using the heat capture system (centralized solar power CSP) to operate the flux power plant.

What is solar power?

Solar power is electricity generated from the conversion of sunlight into electricity by using solar panels or from a solar power plant based on the reflection principle to operate the boiler. the water turns the turbines to generate electricity.

Solar battery

Solar cells, also known as photovoltaic cells (PV: Photovoltaic ), solar cells are devices that convert sunlight into electricity, this generated electricity is also commonly known as energy electricity. Sun. The mechanism of action of this device is based on the photoelectric effect in physics.

See more about how solar cells work:

Solar cells were first created in 1880, in 1954 silicon solar cells created by researchers Gerald Pearson, Calvin Fuller and Daryl Chapin from the US, the original selling price of energy cells. the sun is up to 286 USD/watt with conversion efficiency of only 4.5-6%.

Silicon solar cell technology has been developed until now, major manufacturers in the world such as Canadian , Sharp, Q-cell, .. have improved the technology and raised the efficiency level to 16-25. % and nearly 40% in laboratories. In the future, solar cell technology will continue to be developed to be more efficient in many aspects.

Centralized solar power

The CSP: Concentrated solar power system uses mirrors, lenses, and tracking systems to reflect sunlight over a wide area into a small beam that generates enormous heat. This heat is used to melt salt at temperatures up to 566 0 C. The molten salt is led to boil the water tank to create a strong steam flow that turns the generator turbine.

Historically, the first person to use this technique was the great Greek scientist Acsimet (Archimedes), who used a bronze mirror to focus the sunlight that burned Roman ships.

The advantage of the CSP system is that the raw materials for the production of equipment are quite popular and cheap, high efficiency, does not adversely affect the environment, but only suitable for building power large solar energy.
