Most of the power generated nowadays is produced using fossil fuels, which emit tons of carbon dioxide and other pollutants every second. More importantly, fossil fuel will eventually run out. In order to make the development of our civilization sustainable and cause less harm to our environment, people are looking for new source of substitute clean energy. Because of increasing demands in clean energy, the solar energy industry is one of the fastest growing forces in the market. In recent years, different ways of using the solar energy have been studied. For example, photovoltaic systems directly convert the solar energy into electrical energy while concentrated solar power systems first convert the solar energy into thermal energy and then further convert it into electrical energy through a thermal engine. After a system has been established, it will be very difficult to upgrade the system or change the operation methods. In order to choose the right solar system for a specific geographic location, we want to understand and compare the basic mechanisms and general operation functions of several solar technologies that are widely studied. This paper not only gives a brief introduction about the fast developing solar technologies industry, but also may help us avoid long term switching cost in the future and make the solar systems performance more efficient, economical and stable.
