In this article, we are talking about the Disadvantages and Advantages of Solar energy. Solar energy is energy that we derive from the radiations of the sun. The sun is one of the most powerful sources of energy and it is possible to harness this energy resource through the installation of solar panels. It is an important source of green energy. Its demand has increased in the past few years owing to increased concern about global warming.
Do you have any idea about how much energy the sun provides the earth in just one hour? It provides so much energy in one hour that can fulfill the global energy requirement for one entire year. But sadly, the amount of solar energy that we manage to harness is just 0.001 % of what the sun gives us. However, nations are trying to improve their technologies to make more use of the sun’s energy.
Benefits of Solar Energy
- It is renewable- One of the best advantages of solar energy is that it is renewable. So, it is exhaustible and we can never run out of it.
- Diverse applications- We can use solar energy for several purposes like distilling water, producing electricity and warming homes.
- Lessens electricity bills- Since the solar system will meet a certain portion of the energy needs of your home, electricity bills will obviously be less.
- Maintenance cost is low- Low cost for maintenance is one of the advantages of solar energy. Though you need to pay a large amount to install, after that you can relax.
- Technology development- Technology is advancing in the industry of solar power production. With time, the solar panels’ effectiveness will also increase.
Disadvantages of Solar Energy
- Cost- If you want to buy a solar system, the initial expense is quite high. You need to pay for the inverter, solar panels, wiring, installation, and batteries.
- Storage is not cheap- You can either use solar energy directly or store it in batteries for use during the night. This solution, though good, is expensive.
- Weather dependent- Although you can collect solar energy on rainy and cloudy days, the solar system’s efficiency drops. Solar panels need sufficient sunlight for gathering energy.
- Consumes space- If the electricity demand is high, you need more solar panels for collecting enough sunlight. Solar panels are space consuming and you might require the entire roof for them.
- Association with pollution- Although solar energy systems cause far less pollution than several other energy sources, we can still associate solar energy with pollution. Greenhouse gas emission takes place during installation and transportation of solar systems.
This was all about the advantages and disadvantages of solar energy. Always remember that in spite of its several disadvantages, solar energy still causes far less pollution than the burning of fossil fuels. Moreover, the formation of fossil fuels takes millions of years and there are not enough fossil fuels left on the earth at this moment. So, despite some limitations of solar energy, we do not have much choice as depending on the renewable sources or energy seems to be the best solution in the current situation.
