Solar energy is mainly obtained by converting sunlight to electricity. This is achieved either by making use of PV or photovoltaics or by indirectly using CSP (concentrated solar power) systems. In the case of concentrated power systems, they will be using certain mirrors or lenses and will then be tracking the systems for focusing into a huge area of the sunlight on to a small beam. On the other hand, the photovoltaics will be converting the light into electricity with the aid of photoelectric effect. Solar photovoltaics, solar architecture, solar heating and solar thermal electricity are some of the solar power technologies which will be able to make considerable contributions for solving out various issues.
The solar power is mainly classified into two groups: active and passive solar. The classification is mainly done based on the way they are capturing, converting as well as distributing the solar energy. Some of the active solar power methods may include the usage of solar thermal collectors and photovoltaic panels for harnessing the energy etc. On the other hand, the passive techniques may include choosing materials which are having light dispersing properties or satisfactory thermal mass, positioning the building to Sun and also designing some spaces which will naturally circulate the air.
One of the added advantages with the active solar power technique is that, it will intensify the energy supply and are mainly said to be ‘supply side technology’. However, the passive solar technology will aids in reducing the necessity for other resources and is most often considered as ‘demand side technology’. One of the greatest benefits of the solar power is that, it will be utilizing free energy resources from the sun. This is the technique which is mainly used for the generation of electricity. This in fact can save money too.
Even if any extra power is being produced, it can be sold out to various utility providers for profit. Other than just saving money, the use of solar energy will also aids in making money to some extent. In addition to this, there are several other advantages too. You don’t have to do maintenance work at regular intervals. On the other hand, the cost which is associated with the maintenance while considering long term basis are found to be too low. Another added benefit is that, the solar power is considered as a source of energy which is renewable.
Even though it is not found to be not used up on cloudy days as well as during night time, you can depend on its availability on each and every day. The solar cells are said to be good collectors. They will not be producing any sort of noises similar to that of the other sources of energy. The solar panels are said to be more reliable. The parts are fixed up and hence they will not be moving around. They can last for a longer period of time when compared with the other sources which are producing energy. This is found to be very clean and hence does not cause any environmental pollution.
