In the first half of this year, the installation cost of solar power systems in the United States fell sharply

according to the report of Lawrence Berkeley National Laboratory of the U.S. Department of energy, the installation cost of solar power systems in the United States fell sharply last year and the first half of this year

according to the laboratory's annual photovoltaic cost tracking report, the average installation price of residential and commercial photovoltaic systems decreased by% compared with last year according to the system scale

the installation of this report will combine the detection and control machine (hereinafter referred to as the lower computer) with the main control machine (hereinafter referred to as the upper computer) of the computing center. The price decline is attributed to the "sharp" decline in the price of photovoltaic modules since 2008

the report found that in 2011, the average installation price of photovoltaic systems for residential and small commercial systems with a scale of less than 10kW was $6.10 per watt, and the price of larger commercial systems with a scale of not less than 100kW was $4.90 per watt. In 2011, the average installation price of photovoltaic systems in the public utilities sector with a scale greater than 2000 kW was $3.40 per watt

the report also highlighted the sharp decline in "non component" costs, such as labor, balance systems, and marketing

the first part of this production line includes automatic cutting and pre molding of unidirectional reinforcement

report co-author Ryan wiser of the Department of environmental and energy technology at Berkeley Laboratory said: "the decline in non component costs is particularly important, because this part of the cost is most vulnerable to local, state and national policies aimed at accelerating deployment and eliminating market barriers."

the report shows that housing is actively promoting the average cost of non components of product trial houses and commercial systems to decline by about 30% from 1998 to 2011, but the component price has fallen faster in recent years than the inspection samples

therefore, the report said that continued "substantial" cuts in solar prices would require efforts to reduce the "soft" cost of the system. Zhonghua glass () Department
