You will better appreciate solar heating systems and solar energy as a whole by knowing how the process works. Here is some more info. About the Collectors A solar energy collector gets the radiant energy from the sun to be converted into heat. A solar collector transforms solar energy into heat by taking advantage of the greenhouse effect. These are made of energy particles called photons that are changed into electricity to power various electrical loads. Light from the sun is considered as a renewable energy resource that gives clean energy. Solar panels can be used for different applications like remote power systems for cabins, remote sensing, telecommunications equipment and to produce electricity for commercial and residential panel systems. However, there are certain things and aspects about solar energy that should be discussed with people, especially since solar energy is now being integrated in constructing modern day houses and structures, and are even now becoming a viable source for power and electricity. One of those things that should be discussed involves the risk of using solar energy. The Stand Alone System There are small stand-alone electric systems that are very good at giving economical electricity. These systems are mainly used to power RV, lighting, backup power systems, portable power systems and cabins. The size of the array of photovoltaics or the number of solar panels, as well as the battery will rely on the individual power requirements. This means that you will be able to lower down the cost of your power and energy consumption, especially since you have another alternative source for getting your electricity. Also, people will soon be able to choose where they want to get their electricity from. They could either get it from their conventional utility, or get their clean power from a source that is non-polluting, but is just a bit more expensive than your conventional utility. Sunlight could be changed straight into electricity with the use of PV or photovoltaics. It can also be indirectly converted using CSPs. There are now several devices and structures created which focus and concentrate solar power in various ways depending on the needed use. There are several now several uses of solar power because of the rise of these devices.
