Photovoltaic: "overcapacity" dispute

The proportion of photovoltaic power generation in China's energy structure is still negligible, but photovoltaic overcapacity is still regarded as the core issue of the photovoltaic industry. The key to breaking this contradiction lies in whether it can break through the business model in which the photovoltaic industry survives by relying on “subsidies”.

“Overcapacity is still the basic problem and core issue of the current PV industry,” said Meng Xianyu, chairman of the China Renewable Energy Society. Although a large number of enterprises have been eliminated in the PV reshuffle, from the third-party statistics, it is an indisputable fact that the production capacity is still far greater than the demand.

However, Li Hejun, chairman of the board of directors of Hanergy, believes that “overcapacity” is a false proposition. He believes that by 2035, clean energy will replace 50% of primary energy, and the current total installed capacity of China's photovoltaics is still a drop in the bucket.

According to statistics, the total amount of photovoltaic power generation in China in 2012 was about 3.7 billion kWh, which is less than one-thousandth of the total national power generation (47,79 million kWh). Even in accordance with the plan, in 2015, the total installed capacity of 35GW (about 4 times of the current installed capacity) will be negligible. "We expect that even by 2050, coal is still the most important in China's energy structure," said Meng Xianyu.

“The traditional PV market is mainly ground power stations and rooftop power stations. The market capacity does not depend on the market, depending on subsidies,” said Chen Li, CEO of Hanergy Global Photovoltaic Applications Group. “That is, how much subsidies the country gives? market."

In Meng Xianzhao's view, it is unlikely that China will launch distributed rooftop power generation on a large scale in the short term, especially for families or individuals. “The buildings of urban residents are mainly high-rise buildings, families do not have roofs; rural areas are underdeveloped, and high-intensity investment may not be affordable for many people,” said Meng Xianyu.

NDP Solarbuzz senior analyst Lian Rui believes: "The real BIPV looks beautiful, but the actual market is small, because its development is subject to cost - each household's windows vary in size, and PV modules are only in standardized sizes. Production is cost-competitive," said Lian Rui. "The application of flexible film is almost negligible in the entire PV market system."

However, Li Hejun's fancy PV market does not seem to be a traditional market. "Solar long-distance transmission has no advantages, and its real future is distributed." Li Hejun said. According to Hanergy's plan, rooftop power plants (BAPV) and building integration (BIPV) will account for more than half of sales in the next few years, photovoltaic applications (combined with flexible battery technology) account for 30%-40%, and ground power plants are about 10%. .

Li Hejun is more interested in the broad prospects of commercial roofs, such as industrial plants, shopping malls or shopping centers. Last year, Hanergy signed a strategic partnership with IKEA to install photovoltaic roofs for all IKEA stores in China. Some car sales 4S stores have also become the target of Hanergy's efforts to market. Internet access is one of the bottlenecks that restrict distributed generation.

To make PV development truly market-oriented, and to get rid of the constraints of “subsidy” and “online”, the key depends on technological development and cost reduction. For example, photovoltaic glass used as BIPV can combine the dual functions of building materials and power generation. It can be cut as arbitrarily as ordinary glass, and the price is low. For example, the development of energy storage technology allows each building and even every family to have its own. The energy storage system, then even if photovoltaic power generation is not online, it can also be promoted and developed on a large scale.
