Solar Energy

Solar energy is any kind of energy radiated from the Sun but is usually associated with solar energy technology which converts it into electricity or thermal energy (heat). Solar energy is also essential for plants for the process of photosynthesis and consequently the existence of life on Earth we know today. Solar energy is also a renewable energy and pollution-free which makes it highly attractive source of energy for the future.

Solar energy has been used as a source of energy since ancient times, firstly as a light source, while progress of technology in the 20th century enabled use of sunlight for water heating. More recently the solar combisystem has become popular which uses the sunlight for providing heating both of water and space, and solar cells for converting the sunlight into electricity.

Once installes solar energy systems provide completely free energy and while their popularity is rapidly growing - despite the relatively large initial financial investment when compared compare to conventional energy systems. The majority of solar systems do not provide enough energy to fulfill the energy requirements of a household needs, additional sources of energy are required.
