The solar green electricity from the home roof equal to the cost level of household electricity tariffs will be already from this year to 2012. In the year 2014 at the latest large-scale solar farms can so cheap to produce green electricity such as offshore wind turbines on the sea. While so much disputed costs for solar green energy thus continually take off from year to year, the produced amount of solar electricity is increasing in parallel, rapidly: in the first half of 2011 solar green energy has allowed for the first time the regenerative energy hydroelectric power behind with a share of 3.5 per cent in the gross energy consumption. According to the ruling of the Federal Association of solar industry is the share of solar power up to 2020 to definitely 10 percent increase. And this is not gone talk: the enormous amount of roofs for the production of green electricity is accomplished without interfering with the natural habitats! So that in the future a trouble-free, profitable, fast and accurate installation of solar systems is guaranteed, it is recommended to take decided only trusted professional companies for those interested. You may find that Western Union can contribute to your knowledge. That certainly is the following. Only perfectly planned, technical matters properly mounted and through trouble-free functioning through many years of solar systems generate a safe return. Therefore, an enormous relevance with regard to the overall quality has the level of planning, the selection of appropriate components, the exact technical orientation, as well as the robust construction of the solar plant. Use the possibility of a competent advice..
