While several alternatives for energy production have been found over the years, it is solar energy that has caught the attention of the public. Its efficiency is always questioned and was initially looked upon with skepticism, which has now subsided. But some parts of the planet are yet to deploy this radiant energy source. What are the factors that restrain these regions from employing this abundant source of energy? One big reason would be that the people aren’t completely aware of the wide range of applications and benefits of solar energy.


There are several facts and advantages of solar energy that have not been widely accepted yet. Solar power is the fuel to a better and cleaner energy future. The sun alone can power the whole earth and have much more energy stored within the massive dazzling ball of fire. These are the reasons why investments in solar power generation have increased over the years, making it a necessity to many countries. A complete shift of the planet’s power production from conventional methods to solar energy is expected to take place in the next few decades. Here are some of the facts and advantages of solar energy that make for the current demand for the source.

Facts and Advantages of Solar Energy


  • The source is available for free and is abundant in nature. With the light traveling at high speed, it doesn’t take more than 10 minutes for the sun rays to enter the surface of the earth.
  • Technologies like solar heating, solar architecture, photo-voltaic, solar thermal electricity, and artificial photosynthesis can be used to harness the heat and light of the sunlight.
  • Solar technology has two classifications- active and passive. Examples of active solar technology are the solar thermal collectors and photo-voltaic panels which harness the power of the sunlight. Passive technology is all about constructing rooms in order to orient the space in such a way that it favors the use of sunlight and also to improve the air circulation.
  • The earth receives about 174 Petawatts of solar energy on the upper atmosphere, of which, around 30% is reflected in the space that surrounds. At the same time, the remaining is absorbed by landmasses, oceans, and clouds.
  • Through photosynthesis, solar energy can be converted into chemical energy by the green plants. This energy produced is the source of biomass that, in turn, make up the fossil fuels.
  • Mixing plant varieties and timing the planting cycles are the techniques used by horticulture and agriculture to make use of solar energy effectively. Greenhouses are also employed for converting light into heat which helps in promoting the cultivation of special crops all through the year.
  • Solar power doesn’t contribute to any form of pollution, and greenhouse gases are also not released in the installation process.
  • Nearly zero maintenance is required for the solar panels since it lasts for about 30 years.
  • Solar power is always safer to use than the traditional electric current.
