There are different types of solar energy that are used today. You ask how many are there. According to recent studies, there are three basic types but we will break it down into five different categories. Below I have listed each type and will describe each as it relates to the different uses.
- Photovoltaic Solar Power-Energy that is created by converting the suns rays into electrical energy is called photovoltaic. I am sure you have seen solar panels on houses or businesses before. These are the devices that convert the solar energy into usable electricity. In a simple form it can be used to power solar lighting, examples of this are traffic signs, yard lighting, or security applications.
- Passive Solar Energy-Passive solar energy can best be described as using the sun's energy without the use of mechanical devices. One example could be the energy from the sun concentrating heat on a black painted block wall which in turn would warm your house. Another example could be how the sun
