To meet its climate change obligations, the big suppliers invest more and more into green energy. In particular, the photovoltaic module is thanks the falling prices for your at a high level.

Who flies to Las Vegas, on the approach provides a large, deep blue light-emitting surface in the middle of the desert. It is not water that down there gleams in the sun, but millions of solar cells. To form modules that are part of the solar park El Dorado, they convert sunlight into electricity.

Only El Dorado with ten megawatts (MW) solar photovoltaic power plant of the powerful United States. Soon he will run but much larger solar farm rank. The U.S. energy industry is investing heavily in solar parks: Announced on projects with a total of about 2000 MW. This corresponds to the capacity of two nuclear power plants.

"The module prices have been the end of 2008 by up to 40 percent in 2010 and fell further to fall," said Henning Wicht, an analyst at market researcher I-Suppli Munich. This is a major reason for the sudden rush for solar technology. But the high electricity prices in the U.S. play a role.

In some regions, in peak time a kilowatt hour costs almost half a dollar. The solar power from large solar farms is significantly cheaper. called one more incentive to create tax cuts: Thanks to the so-Investment Tax Credits solar farm operator can deduct for tax purposes up to 30 percent of the investment.
