According to the U.S. department of energy Lawrence Berkeley National Laboratory (Lawrence Berkeley National Laboratory) releasedsolar <a href="javascript:changelink('http://..........com','ZH_CN2EN');" target="_self" rel="nofollow'>photovoltaic.The equipment cost, total inspected the 1998 to 2010 years in 42 states installed in 115000<a href="javascript:changelink('http://..........com','ZH_CN2EN');" target="_self" rel="nofollow'>photovoltaic。Equipment

Berkeley national laboratory research installation of the nearly 1685 MW pv equipment, covers residential, commercial and public facilities, and other departments, found that in the past 18 months, residential and commercial solar pv equipment of the incentive costs in 2010 dropped by an average of 17%, and in the first half of 2011 and within 11%.。The report points out that this is the Berkeley lab tracking data since the start of the annual drop greatly

The report also notes that between 2009 and 2010 artificial, balance system installation, ordinary expenses and other relevant costs the component fell by 18%.The researchers say, because the components are mainly affected by the state and relevant cost the federal government policy, so the effect of the falls of 18% for the future of photovoltaic devices deployment is absolutely important milestone.。In addition, the report also points out that with the unit cost of electricity from the state and the public sector direct cash incentive and the federal government tax incentives of power unit price average size and scale highest than when will both be steady decline.

By the state as the unit of Solar manufacturers, integrators and financing business Alliance Solar Alliance President Carrie · and special (Carrie Hitt) said: "the Solar energy will become our national energy economy in the important part. Solar has reliable, flexible, security features, and now we also found in many areas, compared with the traditional power resources, it also has the advantage of cost. The Solar industry achieved such a great cost reduction and brought many benefits for the economy, and in the national energy structure only accounted for less than 1%. Imagine if the United States can continue to the Solar energy market according to the development and expansion of the sound, so the future will be bright

In the research of the cover during 1998 to 2010, according to the capacity of the weighted residential and commercial solar equipment with the actual cost 2010 face value, said in 1998 from each tile $11 descend to 2010 years of each tile, equivalent to $6.2 each tile down $4.8 (43%).。The report points out that this is equivalent to a year on average, down $0.4 (4.6%), but stressed that 13 years, first plunged appeared in 1998 to 2005.。But between 2005 and 2009, are stagnating.。Until 2010, the average of the previous year and installation costs compared to sharply down $1.3 (17%).
