Photovoltaic power generation on the roof is expected to increase nine times

Authoritative sources revealed to the reporter of the China Securities Journal that according to the “12th Five-Year Plan for Renewable Energy Development” that is being drafted, the installation target for photovoltaic power generation is determined to reach 10 million kilowatts by 2015 and 50 million kilowatts by 2020. It is worth noting that by 2015, the scale of rooftop PV power plants will be 3 million kilowatts, and by 2020 it will reach 25 million kilowatts. As of 2010, the installed capacity of rooftop photovoltaic power stations was about 300,000 kilowatts.

Industry analysis indicates that the domestic rooftop photovoltaic market has gradually opened in recent years. With the support of policy support, the construction of rooftop photovoltaic power stations and promotion of the application of small and medium-sized photovoltaic systems will gradually become the mainstream of industrial development. The relevant component manufacturers and system integrators Will benefit from concentration.

The above-mentioned sources also revealed that the third round of bidding for photovoltaic concessions that had been rumored before had not been considered for start-up this year.

Policy focus on "roof"

Since 2009, the Ministry of Finance, the National Development and Reform Commission and other departments have launched a series of policies and measures such as the “Solar Roof Project” and “Golden Sun Project” to develop the demonstration and promotion of domestic rooftop solar and photovoltaic integrated buildings. Since this year, with the Golden Sun demonstration project as the starting point, the state’s policy support for rooftop photovoltaic power stations has continued to increase. Following the adjustment of the Golden Sun demonstration project subsidy measures last year, relevant departments this year have further clarified the financial subsidy policy of demonstration projects. In recent days, the Ministry of Finance has announced the launch of the second batch of 247,000 kilowatts of Golden Sun demonstration projects this year.

Earlier this year, it was reported that 70% of the second round of 280 MW photovoltaic concession bidding projects launched last year had not started until May this year. The main reason is that project investment income is expected to decline.

Analysts pointed out that although the National Development and Reform Commission recently determined the benchmark price for photovoltaic power generation on the Internet, there is still insufficient power at the corporate level. Under this circumstance, roof photovoltaic power plants began to exhibit greater potential because of their ease of grid connection, relatively low investment costs, and relatively clear subsidy policies.

Li Shengmao, a senior research fellow of China Investment Advisor New Energy Industry Group, said that countries such as Germany and Italy have adjusted their respective subsidy policies, promoted small and medium-sized photovoltaic systems, and promoted the construction of rooftop solar power plants. This also shows the future development trend of rooftop solar energy industry in the world. . In this context, China will also vigorously promote the development of rooftop photovoltaic power plants.

Industry growth or substantial increase At present, the promotion of rooftop solar power systems in China is still insufficient. It is understood that the “Golden Sun Demonstration Project” (90% of the project is a user-side photovoltaic power generation project, that is, a rooftop solar power station) has started nearly 600,000 kilowatts demonstration projects in the past two years, and so far only about 300,000 kilowatts have been completed. The “Twelfth Five-Year Plan” proposes a 3 million-kilowatt installation target, which is equivalent to a 9-fold increase on the current basis. By 2020, the installed capacity of 25 million kilowatts is equivalent to 80 times the current scale.

Chen Yanpeng, researcher of China Securities Research Center, said that at the end of 2010, rooftop PV accounted for 28.8% of the total installed PV capacity. Combined with the total installed capacity of photovoltaic “Twelfth Five-Year Plan”, the proportion of photovoltaic rooftop projects in 2015 is basically the same as at present. It is expected that the compound growth rate of the industrial scale will reach 63.5%. In 2015-2020, the roof photovoltaic industry will become the core of the development of the entire industry. Its installed capacity will reach half of the total installed capacity, with an average compound annual growth rate of 52.8%.

Analysts pointed out that the development of rooftop solar power generation will bring about the market adjustment of photovoltaic cell technology such as crystalline silicon and thin film. Chen Yanpeng believes that although crystalline silicon is currently the mainstream of the industry, due to its strong flexibility, thin-film batteries have advantages in BIPV architectural integration and other fields. In addition, the cost of thin-film batteries is relatively low, and the conversion efficiency is continuously improved. In the future, thin-film battery manufacturers will enjoy more benefits.
