Solar energy is one of the great solutions to the global warming which has been a menace and a topic of debate for a long period of time. It has been revealed that, one of the strongest effects of Global Worming is a raising temperature and longer summer. In this case we could benefit from solar energy and prevent further pollution created by conventional energy. In this paper, the different types of solar panels will be addressed in order to determine the laws governing the field of solar energy. Importantly, in order to start looking at the solar energy it is of great importance to look how expensive are the solar panes and their effectiveness (Solar Energy International 300).
