A Guide To Solar Energy And Solar Panels

Today there are two types of solar cells. - Firstly there are what is known as Solar Thermal Collectors, which focus solar energy into a fluid medium, usually water.Water is then heated and can be used anywhere in your home or business, etc. as needed. - Secondly there is the photovoltaic module which primarily converts the sun's energy into electricity, and likewise can be used in the house, business etc.This kind of energy can be a battery, for when you need to save it for a later time. Alternative power is not new and has been in existence for quite some time.It's easy to use. Calculator's and many watches have used solar energy for years, even swimming pools use the suns energy into solar heating the water. Today you can build larger plates for energy collection making it ideal for families and businesses to save even more when it comes to cost reduction on energy bills. Nowadays the National Grid even use solar panels to supply them with a small amount of usable electricity. How do they work? When sunlight is reflected on the solar panel, part of energy in the conducting material absorbs into the internal structure, which in turn, that electron strikes loose in the silicon, so that they move freely. This flow creates what is known as a current, then by placing metal contacts on solar energy panels the current can be drawn off as electricity which can then be directly supplied to houses, businesses or wherever it is needed. WHY SOLAR ENERGY - There are significant savings in energy costs. - Also there is the Green issue and people are aware that by using solar panels they are reducing their carbon footprint.The solar panels emit virtually zero emissions of carbon dioxide.Solar panels reduce our carbon dioxide emissions by approximately 1.2 million tons per # 39, annual. - Solar panels are ideal for rural areas, where electricity coverage by main providers is limited.
