In the modern sense, however, solar power refers to the generation of electricity from sunlight using photovoltaic cells. With this in mind, what are the pros and cons of solar power? The major advantage of solar energy is that its source is practically renewable - the Sun! Because of this, apart from the initial cost in materials and incidental pollution due to manufacture, transport, and installation, solar energy is 100% clean and environmentally friendly. It generates power without using up any further resources or causing any pollution. In fact, it does not even generate much heat or noise!.
Another item on the list of pros and cons of solar energy is that because it does not use up any resources while running to produce power, it has the potential to be cost-effective. Apart from the initial outlay of components and labor in installation, solar energy systems typically require little maintenance and no fuel at all. These systems will just keep on producing clean energy that is also practically free.
However, one of solar power's big disadvantages is that it requires such a big initial outlay. This is one of the major disadvantages of solar energy and is a big hurdle it must overcome, if it is to gain bigger acceptance and use. With the current situation, fossil fuel fed energy is still much cheaper to obtain than any of the alternatives, which is why it continues to be used in spite of its increasing drawbacks.
Another disadvantage of solar power is the fact that it can only generate power during the daytime. Solar energy collection is adversely affected by weather (cloud cover), and pollution, which limits the amount of sunlight that reaches the PV cells. Advances in the use of batteries and increasingly efficient photovoltaic cells are helping to lessen these disadvantages.
These pros and cons of solar power are still mostly balanced: supporters hope for the pros to outweigh the cons in the near future.
