Sempre que estiver na moda pode chamar! estarei sempre aqui para ajudar em tudo que precisar!comente se quiser manter contato! unha de londres . temos esses tipos de unhascaso esteja com vontade depintar a unha veja os modelos aqui :) Beijinho amores ;) Work on energy sourcesWork on energy sources has been done under the supervision of Professor Alex and with the participation of other teachers silvanno chemistry, Hilton of geography, math, IDMA elneide English with the intention to be submitted to all renewable energy sources, which were divided between eight groups they are: wind, solar energy, biofuels, biomass, geothermal energy, hydraulic, hydroelectric and tides. Solar energy: it is an energy from the Sun if Dah cards photovoltaic which is the conversion of light energy into electrical energy. Not be confused with solar heat that has a principle of operation quite different. How it works?To utilise energy that comes from the Sun, we need to basically three elements: photovoltaic modules, drivers load and batteries. The Siemens photovoltaic modules are constructed from chips of Silicon monocristalino, superior quality to similar and high - efficiency. Siemens is world leader in manufacturing and production technology of photovoltaic modules, being the only company in the world that has the technology powermaxa / topsa.The second element, the driver load, is a fundamentally important to preserve the batteries, increasing its useful life. Siemens offers a complete line of drivers load generation. Batteries are the elements that armazenas energy. With the help of them, consumers may use at night or in periods of bad weather energy radiated in days of sunshine.Because solar energy?Because it is a clean energy, clean, reliable, rational, that does not require maintenance and not consumes no fuel. For these reasons, can be used in many applications. In Brazil, where we are privileged by Sun, there are thousands of facilities for rural electrification, fences electrical pumping water and telecommunications use photovoltaic solar energy.Photovoltaic solar energy is expensive?Over the past 20 years, the cost of photovoltaic solar energy fell so spectacular. Today, for the vast majority of applications, you can pay the investment made in about two years or less.Because solar photovoltaic Siemens?Because the Siemens is a world leader in the manufacture of solar modules, already having produced approximately 150MW in photovoltaic modules. Siemens is a company that constantly invests in technology, aiming always consumer satisfaction and excellence of their products. In Brazil were already sold more than 50,000 photovoltaic modules for the most diverse applications in more remote locations.Doubts1 Can i use a solar panel without the battery?Yes, the solar panel generates power directly from Sun and you can light a lamp or trigger an engine without using battery power (batteries). However the systems of energizacao residential need battery to accumulate energy produced during the day that will be used even at night. The use of solar energy now be constant and continuous avoiding that variations of insolation affect the performance of equipment installed.2 Is there any grounding system photovoltaic solar energy?The system user solar energy needs to be first and foremost a be aware and
