Solar Energy – The Advantages and Disadvantages
The main advantage of solar energy is that it is free, no one will ever charge someone for using the sun and this is why on average the advantages outweigh the disadvantages when it comes to solar energy and in particular harnessing solar energy using a solar panel. Without the sun we would not be on earth and nor would anything else, so why don’t we harness the energy it gives us to create energy for ourselves?
Another important advantage when using solar energy is that it is environmentally friendly, once you have created your panel you do not need to fuel it as it is fueled by the sun and hence there is no pollution created. Solar energy is one of many renewable energy sources including wind, hydro, biomass and geothermal, but it is still the easiest to harness, yet it is still one of the most under used sources. Once created there is no maintenance to keep a solar panel this is because it has no moving parts so it cannot break or stop moving. This makes it very reliable and independent, it is a set and forget appliance.
Although solar cells are efficient, cheap and reliable they still have a few disadvantages. The most evident is that solar cells have a high initial cost. This is due to the materials and skilled individuals who make the solar cells. These costs can be reduced if you make your own solar panels or find a good deal in your area. Solar panels generate little to no energy during the nighttime which means you will need to store your energy for night times. Despite these there is one disadvantage that outweighs all of these. This is that some of the sun rays that hit the shiny solar cell are not absorbed, they are instead reflected away, this makes solar panels slightly less efficient, even if it is only 10% of the overall rays.
Solar panels are investments, they should not be used to save money in the short term and should only be used for long term gain. Governments around the world are now thinking of giving grants to people with panels. This should be a big incentive to either buy a solar panel or make your own as not only will you save money on your electricity bill, but the remainder of your energy bills may be cut by the government.
To harness the power of solar energy build a solar panel.
