Solar energy, advantages and practical applicability

Solar energy has a great effect on your life. Why you choose use solar energy for your home. Because it helps you, for everyone and in the community a lot of benefits. In this article, I will give you a deeper insight into the application of solar energy as well as its advantages.

Why choose solar energy


The importance of finding clean energy sources

While traditional energy sources, such as coal and oil, are running out of stock, high prices, unstable supplies, and many alternative sources of energy are of interest to scientists, especially energy sources. Sun. Access to these new sources of energy not only contributes to the energy supply of the society but also helps to save energy and reduce environmental pollution.

Clean energy


Currently, three types of solar cells are used in the world: crystal solar panels, polycrystalline solar cells, and amorphous thin films. In particular, amorphous silicon (a-Si) batteries are of particular interest because of the operating time of the battery, which shows stability and high efficiency.

By other experiments, scientists also determined that a-Si batteries could work in cloudy conditions and even in high-temperature environments where other batteries could not work. This has clarified why in the results table on the battery a-Si gives more power than the two batteries.

Energy and energy security are always seen as fundamental for safe and stable development for all countries and territories. So, in the context of increasingly depleting traditional energy sources, the development of renewable energy, including solar power, is seen as a solution to the energy problem for all economies.

The economics of solar energy

If the power projects are usually the capacity will be very modest, large investment costs. Also, wind power is calculated, to do 1MW wind power requires 2ha of ground and only in some areas. Putting wind turbines on is also problematic regarding performance, resistance to storms.

Economic of solar energy



But with solar power, to make 1MW solar power is the only 1ha of space and can be done in all areas of the country, especially using roof panels, the grid connected solar cell with a capacity of 3-4kW ranges from $ 4,000 to $ 5,000. And if any house put the capacity will be very large

Practical application of solar energy

There are four types of solar technology currently available in the market. It’s a household-scale, solar-powered technology that’s used for hotels, restaurants, hospitals, military and service centers, for villages like public lights, sounds TVs and stations for battery charging.

Solar water heaters are a relatively developed and commercially viable technology that has been adopted both on a household scale and on an industrial scale. Households and businesses are more willing to invest in solar water heaters because they can save on electricity bills. So far, the technology of producing solar water heaters can easily mobilize capital from the private sector.

The use of solar energy for water heating is also highly recommended in the military. Many nations also exchange research and promote the use of solar energy in the military. Up to now, solar water heating systems have been installed in military schools and facilities, especially in units on islands.

Difficult to start applying this technology



However, the use of solar water heaters in many countries is still low. In a country that is beginning to adopt the solar technology, only 60 collective systems and more than 5,000 household systems have been installed. About 90% of solar water heating systems are used in urban areas and 5% in rural areas. Approximately 99% of these systems are invested by households, and 1% belong to public facilities such as hospitals, kindergartens, hospitals, schools, hotels and restaurants. Boiler systems with an area of ​​10 to 60 square meters of solar panels can provide 1 to 5m3 of hot water daily at a temperature of about 50 ° C to 70 ° C.  Solar household scale solar water heater systems with a panel area of ​​1-2m2 can provide about 100 to 300 liters of hot water at temperatures between 40 ° C and 70 ° C.

Use the solar energy is also saving 

  • Use solar energy to reduce your energy bill
  • Using solar energy is helping to protect the earth
  • Using solar energy is a form of investment
