The trailer array is done by retrofitting present vehicles with little stability. Practical Use The first commercial electro-solar hybrid car, called the Venturi Astrolab was introduced in 2006. Some companies in May 2007 also worked to change a Toyota Prius to utilize solar cells to create up to 240 watts of electrical power under the sun. This helps show people that solar energy is one of the best alternative energy sources for the future. However, don t simply take my word for it. Instead, check these different solar energy figures and statistics and see for yourself if whether solar energy is indeed everything that people are claiming it to be. Electrons are then released from the atoms to produce electricity. The photovoltaic effect is achieved when light is converted into electricity. You can then have direct current electricity. When the power enters an inverter, you can get 120 volt AC conversion, the same electricity required to power the house. At Present Today, Germany has become the primary PV market worldwide after they revised the feed-in tariffs for the Renewable Energy Sources Act. Spain has become the biggest PV market after 2007 after it adopted the same feed-in tariff structure. Spain installed half of the PVs all over the globe, accounting for about 45%. This means that reliability can be acquired day by day. You can expect to continue getting power and energy from the sun for several decades without having to recharge batteries or keep purchasing new parts. Even though the energy may not always be readily available during cloudy days or at night, the availability is still there everyday. government actually spends a lot of money on paying off the energy consumed by these hot water heaters, about $13 billion every year, possibly making it the single biggest energy consumer in your home or work place. Solar energy systems used on hot water heaters can actually help you save a considerable percentage on your utility bills, over 85% of the total electric water heating cost of your home.
