Renewable Solar Energy

Nov 13, 2011 Author: xiandra | Filed under: Solar Energy

The life on earth is dependent on solar energy and the smallest form of life like the microbes and plankton are also dependent on the solar energy for their survival. Solar energy is an environment friendly energy that is devoid of any carbon emissions which lead to pollution. It can be utilized productively and cost effectively across the world. You don’t have to reside in a desert to benefit from solar energy!

How does the renewable solar energy work? Majority of the devices that are powered by solar energy use the photovoltaic cells, which produce electricity as soon as they are exposed to sun rays. These cells consist of panels which comprise of two layers and these layers become positively and negatively charged, once the sunlight falls on them. This leads to the production of electric current, which can be connected to the main supply of your house, and used to run your electric devices like computers, phones and blenders.

Disadvantages of Solar Energy

Solar energy is still the best clean renewable alternative source to use compared the available dirty fossil fuel technologies. With the price of the solar panels continuing to decrease with improved technology and more widespread manufacturing there is likely to be a widespread increase the use of the solar cells to generate electricity for both home and industrial purposes.

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 effects…… As we already know solar energy needs the sunlight to produce and convert energy into electricity so solar panels can only be useful during the day and at night your expensive solar equipment is useless. 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.
