Solar power or cheaper than 'black' energy

In China, & other; Green & throughout; Energy is expected to outperform & other; Black & throughout; Energy. Solar power for its advantages of clean, reliable enough resource and technology, leading the renewable energy development. However, bound by the high cost of solar pv system. However, the Chinese and foreign researchers, said of the city industrial and commercial solar power supply system in China has been much cheaper than the grid. The stimulus or can cause of China's commercial and industrial solar energy systems using a dramatic increase in the near future. Relevant papers published online August 12 in the natural & ndash; Energy. '

in recent years, China has not only become the main producer of solar photovoltaic power generation, and has become the main market, interest in the prices of Chinese solar power is increasingly strong. But China's solar photovoltaic power generation cost is influenced by many factors, make it difficult to understand solar photovoltaic system power supply to the end user's price, whether with the power supply or the desulfurization of coal electricity price is the same or less.

the researchers say, when the price of solar power is higher than the price of power supply, procurement solar system to stimulate the economy will decline. In order to solve this situation, many developed countries adopt the practice of subsidies for solar power system. Developing countries such as China may not provide a massive subsidies, but the labor and the system hardware cost is low, may mean that the price of solar power can and the price of power supply.

the royal institute of technology in Stockholm, Melanie darren university and tsinghua university of China institutions researchers estimated the 344 Chinese cities such as electricity and solar power system power output, with the city's power grid electricity price compare a; Estimate the price of solar power grid scale, and comparing with the coal price.

in combination with the total project investment, output and prices, analyses the construction and operation of distributed solar photovoltaic projects of net costs and net income, after the team reached the result that all of these cities can be without subsidies, commercial and industrial solar energy photovoltaic system for less than the cost of the power grid to generate electricity. In 22% of the city, the grid solar power system of power generation costs can be competitive with coal desulfurization benchmark price.
