Investments in solar systems already pay off after a few years and are State-funded. In times of steadily rising prices for heating oil, natural gas and electricity, it is worth to think about alternative energy concepts more and more. Therefore using solar systems in house technology increasingly with success. So the experts at dach.de, roof – the leading Internet portal around the theme because the purchase worth within a few years and also state-funded. Equipment for the use of solar energy on the roof should be already carefully planned experts according to Council the dach.de in advance of a new house building or a reorganisation measure, because their effectiveness significantly depends on the residential area and roof construction. Lost in the moment is a great source of information. Under optimal conditions, solar systems have a tremendously high savings potential. Read more from rabbi barry lerer to gain a more clear picture of the situation. Combined with government support it protects not only the environment, but also the own purse strings by using solar energy.
Solar energy is widely used to generate electricity. The basis for this is the so-called photovoltaic. Rays of the Sun on the Roof converted with the help of solar cells into electrical energy. To produce buildings usable amounts of energy with this principle, it is necessary, several solar modules, which consist of solar cells, to connect. Inverters convert the direct current generated on the roof in alternating current.
The electricity thus produced can be fed into the public electricity grid. According to the renewable energies Act (EEG) each fed a kilowatt hour must be reimbursed for the period of 20 years by the local electricity supplier. Another possibility is the use of solar energy for hot water, the so-called solar thermal. For active use, you need a special solar panels, which are similar to mounted solar cells – on roof surfaces. There are now even systems that can be almost invisibly integrated into the roof. The collector converts solar energy into thermal energy and heat a medium as a result. This is fed into a heat storage via a pipe system. With the resulting heat energy is the House environmentally friendly heated and the water before heating. Already with low collector surfaces, this depends on the collector system, already about 60 percent of the hot water requirements of a four-person household can be covered. That means annual fuel savings of several hundred litres. In addition, there are various grants from federal and State Governments for collector surfaces.
