The United States set the cost of photovoltaic cells changes
The United States Department of Energy’s Lawrence Berkeley (Lawrence Berkeley) National Laboratory in October 2009 released the United States set the cost of solar photovoltaic cells research report pointed out: From 1998 to 2008, the average cost of these systems fell by more than 30%. In 2008 the cost dropped more than 4%.
Reported that the recent decrease in cost, mainly photovoltaic module cost reduction results.
From 2007 to 2008 set-up costs drop marks the trend of the previous three years, during this period, with the United States and the rapid expansion of the global PV market, the module price and non-module sony VGP-BPS8 battery costs under great pressure, with the solar energy industry expansion of manufacturing capabilities as well as the global financial crisis occurred in 2008, this dynamic shift, resulting in a decline in the price of the entire module.
In contrast, between 1998 and 2007 the decline in costs was mainly due to the non-module costs, such as labor costs, management costs, the cost of inverter and system balance.
Studies have shown that between 1998 and 2008 installed in 16 states there are 52000 grid-connected photovoltaic systems, the survey found, with an average installation cost (in real 2008 dollars) from 1998, 10.80 U.S. dollars / W down to 2008 7.50 U.S. dollars / W, the average had dropped 0.30 U.S. dollars / W.
As time goes by, small-scale photovoltaic systems, if applied to individual households of small-scale photovoltaic power generation system, the largest cost reduction. In addition, in 2008 built a small residential photovoltaic sony VGP-BPS8A battery,sony VGP-BPS9 battery system, its installation costs have emerged as the size of the increase of more economical, less than the size of an average 2KW of 9.20 U.S. dollars / W, while the 500 ~ 750KW of large-scale commercial system an average of 6.50 U.S. dollars / W.
Different states, installation costs are not the same as in 2008 and the installation of the system were smaller than 10KW, flat-fee cost of Arizona as low as 7.30 U.S. dollars / W, followed by California, the average installation cost of 8.20 U.S. dollars / W, higher for the Pennsylvania and Ohio, for 9.90 U.S. dollars / W.
