Solar Energy

Introduction

The energy produced by the sun is called solar energy it is a clean renewable source of energy it can be hardest by solar collection methods such as solar cells and can be converted into usable energy such as light energy heat energy, etc. It is a reliable energy they provide free energy to heat your home and water solar panels were invented in 1973 when caring for the environment didn’t see as very important. Solar energy become more Useful each year since 1973. Solar panels are a sustainable source of energy. all solar systems work on the same basic principles. These panels first convert the Solar Energy or sunlight into DC. The DC power can then be stored in a battery or converted by a solar inverter into AC power which can be used to run home appliances. Depending on the type of system access solar energy can either be fed into the electricity grid for credit, or stored in a variety of different battery storage systems. In easy words, we can say that the working of a solar panel can be described as:

  •  PV panel consists of many solar cells which are made of materials like silicon The individual cell is designed with a positive layer and a negative layer to create an electric field just like in a battery.
  •  Electricity flows from the solar panel in the form of direct current.
  •  Next, it is passed through an inverter, which converts electricity to an alternative current.
  •  Now this electricity is ready to be used in your home or business.

Important information

During a typical sunny day, 1 square meter of solar cells exposed to the sun at the moon will receive about 1 kilowatt of an idea from the sun. The majority of solar cells available today convert about 15% of this into electricity generating 150 words in full Sunshine.

Importance of solar energy

Traditional energy sources such as oil natural gas etc face several challenges including rising prices and growing environmental concerns renewable energy sources such as solar, biomass, geothermal, hydroelectric, and wind power generation have emerged as potential alternatives to address some of these concerns.
Moreover, solar power generation has emerged as one of the most rapidly growing renewable resources of electricity at any moment about 1.7 *1017 volts of energy from the sun strikes the Earth which can be used to produce electricity.
Solar energy is also used on a small scale for purposes other than those described above. In some countries, for instance, solar energy is used to produce salt from seawater by evaporation. Similarly, solar-powered desalination units transform salt water into drinking water by converting the Sun’s energy to heat, directly or indirectly, to drive the desalination process. Solar technology has also emerged for the clean and renewable production of hydrogen as an alternative energy source. Mimicking the process of photosynthesis, artificial leaves are silicon-based devices that use solar energy to split water into hydrogen and oxygen, leaving virtually no pollutants. Further work is needed to improve the efficiency and cost-effectiveness of these devices for industrial use.

Advantages

Solar Energy is very important as it is a clean and renewable resource of energy. This means that it will not damage the earth in any way and in addition, it is available daily. Similarly, solar energy does not cause any kind of pollution. As it is environment friendly it is very important in today’s world. It is so much better than other polluted sources of energy like fossil fuels Coal oil and natural gas. Further, it also has low maintenance costs. Solar panel systems do not require a lot of solar power energy moreover they come with 5 to 10 years of very beneficial warranty. Most importantly it reduces the cost of electricity bills. In other words, we use it mostly use for heating our homes and cooking. Solar energy Drop The Unity will cost and help us save extra money. Disadvantages
Solar panels can be expensive to install reducing in a time lab of many years of saving on energy bills to match initial Investments. Electricity generation depends and telling on a country’s exposure to sunlight; this could be limited by a country’s climate. Solar power stations do not make the power output of similar size conventional power stations they can also be very expensive to build. Solar power is used to charge batteries so that solar-powered devices can be used at night. The battery can often be large and have it taking up space and needing to be replaced from time to time. The biggest disadvantage of solar power is that it can not be used during the night because of the absence of sunlight while on the other hand, it can be used to store the energy for later use or the use of the next day.

Facts of Solar Energy:

  • It is the cheapest energy.
  • The efficiency of solar energy.
  • Panels produce energy without direct sunlight.
  • Panels can last up to 30 years.
  • It is the most abundant energy on the earth.
  • Countries investing the most in solar energy.

Moreover, as it is considered the most abundant energy on the earth 173000 terawatts of solar energy strike the earth continuously. It is about ten thousand times todays worlds total energy use. The first silicon solar cell, the precursor of all solar power devices was built up in 1954 by bell laboratories.
When it comes to the power of solar energy we can tell that the average solar panel produces from 170 to 350 watts every hour which depends on the region or the weather conditions. According to the distance, this works about 0.17Kwh to 0.35Kwh per solar panel.
As solarthe  panel is a beneficial and renewable source of energy it also plays an important role in reducing greenhouse gas emissions and mitigating climate change which is critical for the protection of humans, the wild life and eco systems. And according to the research it improves the air quality and reduces the water use from energy production.
Last but not the least benefit of solar power is it cleanliness as it does not produces any kind of air pollution or green house gases when operating.

Conclusion.

And at last it proves that this energy named as solar energy is a superb source of energy because it does not contaminate secondly its inexpensive and lastly it is renewable.
