solar power articles 2009
Two solar energy technologies exist, passive and active technology. The technology is passive photocell panels or photovoltaic film that receives sunlight and generates electricity more suitable for a space station or a house. Technology is an active solar thermal using an antenna to concentrate sunlight to produce steam, which in turn powers a turbine that generates electricity. Another technology assets, which is not being promoted, is hidden from public view, are using the Stirling engine to move a power generator.
The passive technology is ready to go, and there are some houses that have already installed the system. This system is totally clean, backed by the American Solar USDOE initiative, it requires enough space on the roof to the position of the panels or film, and uses an inverter for converting direct current into alternating current household can use. The utility companies also have developed a net metering system to buy electricity in terms of households having a surplus of electricity. The new federal tax law "Law on Emergency Economic Stabilization 2008 "from January 2009 provides a tax credit of 30% of the cost of a solar system. Some states also are offering great incentives to install systems solar energy, although with the current economic crisis in these paybacks can be reduced or delayed. The rest of the recovery has to come from genuine savings generated in time for the system of the utility company. This passive solar system is expensive, starting today, and recovery is obtained in 8 years savings. Photocell or photovoltaic film panels are of low efficiency and tension, and compares poorly with the option of purchasing electricity from the utility company public. Currently require 13 to 15 photocell panels to generate 2.5 to 3.0 kilowatt hours of generation capacity.
Walmart has established a plan driver to install photovoltaic panels in several of its stores. If the system produces a change, will be mass applied in all its stores, as it has enough space now the roof is not used.
The solar thermal system is not suitable for households and is used mainly for large utility companies. However, the system activates based on a Stirling engine to move a generator that could be applied to households not available for mass distribution. Despite all its components have been developed, no team has integrated solar energy generation, or an appliance. This home system or appliance must be very low cost because it requires: a solar collector or plate that could cost about $ 200 USD, stiriling engine at a cost of $ 350, 3 KW power generator per hour at a cost of $ 350, and the battery bank, that is the subject of ticket expensive and could run several thousand dollars, to store electricity, if the system is a separate unrelated to the electricity grid. If the house is supplied by a utility, then the battery bank is not necessary and net metering system with the utility may be used. Besides the sun collector plate the rest of the system can be packed in two boxes. Stiriling One has a motor and generator power, and the other with battery if a place unrelated to the network. You can also have a gas heater installed as a backup when there is a lack of sunlight, making this an alternative very reliable.
Apparently, there are companies in the United States, New Zealand, India, Sweden and other countries try to develop the engine stiriling. A few companies get funding investment funds to develop the engine for this device stiriling home. Infinia Corporation, a U.S. company has an advantage because they are currently producing one pounds large engine power to 10 homes at a time and the installation of many of them in a centralized photovoltaic park in California. Other companies should not be discouraged, Because markets are so huge, it is not enough room for all suppliers. In the U.S. alone there are 124 million potential households that could use the equipment solar energy, as well as commercial and industrial sites.
Have the electrical power may be the initial steps for the return to the systems sustainable. Today, the sun's light and heat, provided by God and nature, free to all of us to use and enjoy. A home solar-powered generator providing clean energy playing field and allow all nations rich and poor, to devote their funds to other worthwhile services such as health and social education. Rich nations have the power grids and power generation capacity suddenly feel that there would need to further increase the generation capacity energy and hopefully that would stop all plants that pollute.
