Solar energy a useful and helping medium for everyone, but it is not always filled with benefits. Although we all are discussing its advantages and new technologies being involved with it, but there are many things which are not making everyone happy on this earth. The biggest disadvantage of solar energy , about which we can talk is the initial cost that a user of this energy has to bear. Manufacturers are using best quality material in solar panels and other products, using solar energy to work. They are not considering the fact that it is increasing burden for customers.
Manufacturers justify burden of cost with years of guarantee and long life of their products, but how it would be possible for someone to reduce its expenses of utility bills when he is not able to afford the product in beginning. This is biggest reason that customers avoid to purchase these systems for their personal use. Other shortcomings for solar technology are as follow :
Disadvantages of solar energy:
Solar energy is indeed the best renewable energy, and it is saving this planet from decline of non renewable sources. But there are many disadvantages associated with it, and these are making people suffer with some difficulties.
Solar energy is not available at nights: solar energy products can facilitate humans when these products come in contact with sunlight. But it is not possible that this element remain available all the time. Therefore this is counted as one of the biggest disadvantage of solar energy. Sunlight is not available at night times, and blows in some specific region regularly. It becomes impossible for users to get electricity when solar energy is absent.
Solar Inefficiency: common criticism that is faced in this regard is about inefficient production level achieved with help of solar energy. Solar devices purely depend on factor that how much of radiations they receive with sunlight to convert into electricity. Solar power always carries same level of radiations but it does not always give same radiations on one region only. As sun and earth revolves positions of regions changes and with that power of sunlight as well. This effects production level of solar panels and customers suffer with different problems related to less efficient supply of electricity.
Solar systems occupy large area: another disadvantage that is faced with solar energy and its systems is area that they occupy. The system that is used to convert solar power into electricity is solar panels, and these panels are very expensive and large in size. Especially when you are installing solar systems to run an industry sufficiently then you are need to install multiple panels there according to your need. To place these panels you are in need of space where you can install this system efficiently. This thing is considered as drawback.
Effects of location on solar energy: to get proper and sufficient supply of electricity it is important that solar panels are placed on those locations where they can get proper sunlight. Mostly this is counted as drawback with use to solar power, because all users of this system are not located on places where they can get direct solar power. It shows that those users cannot take benefit from solar energy as they are surrounded with obstructions like high buildings and other possible issues.
Pollution: the material used for manufacturing these panels is silicon. Use of this material has increased efficiency of solar products but pollution that is founded in air can disturb their working badly. Besides this other toxic materials including mercury, lead and cadmium are used to improve ability of solar systems. These materials also get affected by gases that are founded in environment.
