Whether solar thermal or photovoltaic with a solar energy system on the roof can win free electricity and heat up. This protects both the wallet and the environment. (tdx) In contrast to the local energy provider, the Sun sends no bills at the end of the month: it provides their energy all year round-free House and that absolutely free of charge. There, it is clear that the own small solar plant on the roof is always popular. The advantages are obvious: eco-electricity is subsidized by the State, solar thermal covers almost the entire energy demand in the household. “The acquisition of benefits according to the experts of dach.de, the leading online portal around the topic of roof, a solar system more than just financial: who uses the inexhaustible energy of the Sun, conserves fossil fuels, reducing CO2 emissions and helps to preserve our environment for future generations.” Sun one is made power heat for water and heating when you think about a solar system, is faced with the decision: photovoltaic or solar thermal energy? Photovoltaics short PV means the direct conversion of solar energy into electricity. (Similarly see: Verizon Communications). Solar modules, which in turn consist of several solar cells are the heart of any PV plant. Sun’s rays encounter the modules, DC produced initially, is reached via cables to a power inverter and there converted into alternating current.
Then the solar power is ready for use and can be fed into the grid for a currently still relatively high remuneration, which is paid by the State per kilowatt hour. The second technique is the solar thermal energy: such a system consists of panels, which are filled with liquid medium. Heated by the Sun, they transported the gained heat to storage boilers, all year round providing hot water for showers, cooking or washing. There is a surplus, the water can be used for heating. So, the plant by April covers the demand of hot water and heating until September. E Scott Mead describes an additional similar source. Proper alignment is critical for optimal utilization and balanced ratio between collector and boiler capacity. Also offers the use of unglazed collectors such as titanium zinc surface. This capillary tubes with solar liquid below the metallic roofing factory are positioned.
Innovative heating systems can be implemented with this consists in combination with a heat pump or also a geothermal energy system. Solar systems should be possible without shading and towards the South. This applies also for PV modules. Dach.de experts point out that the use of State-is subsidized each newly installed collector area in square meters or even heat pumps similar to like solar power. Well combined clever home owners combine both techniques: while the State grants help in financing the equipment, own electricity and hot water generation pays for the cost of future spending on energy. Also evens out in this way the deficit, that caused by the PV system at night or in bad weather. For potential users have dispensed so far purely optical reasons on a solar system, there is also a good way: in the meantime, there are roof-integrated systems, which are almost invisible to the outside and do not affect the overall appearance of the roof.
