The solar energy is proving to be the best alternative source for producing energy. But as they say all things invented have their own disadvantages or bad side; this article will discuss some of the disadvantages that solar energy has.
Another disadvantage of solar energy installation is that it requires a large available area ( generally roof space) for the system to a high enough KWh size to be efficient in providing a large source of electricity. This can be a problem in high density urban areas where space is minimal and often expensive to own as well in some cities. High Pollution can also cause a disadvantage to the solar panels as it can degrade the efficiency of the photovoltaic cells.
Clouds also give a similar disadvantage, as clouds lessen the energy of the sun rays. These disadvantages were more pronounced with the older solar components and designs however, and the newer designs of solar panels have features that lessen these kinds of effect. However, the use of solar battery chargers helps to reduce this disadvantage, or even better in Australia & Germany there are effective Feed In Tariff programs that allow people to sell their solar produced electricity during the day at a profit & buy fossil fuel produced electricity at night for a cheaper rate.
It' s important that solar panels are properly placed where they can get the maximum amount of direct sunlight so that your systems optimal output can be reached. Obviously Solar panels should not be placed in an area that has obstructions like buildings and landscaping, and the direction & aspect of the roof is also very important. So these are the disadvantages of making the switch to renewable solar energy. People should always consider the positive or the advantages of solar energy. At this point in our environmental crisis solar energy is proving to be one of the greatest invention of mankind, and it is set to become even more crucial and bigger in the future!
