Rooftop solar photovoltaic is very useful, not only can self-generated self-consumption, not enough can also be online cash. In addition, with photovoltaic modules to raise more than 2 meters of the roof overhead, transformed into a sun room, playing tea and chatting family recreation area or children's play area is more than appropriate.

In the “double carbon” strategy in the implementation of the background, as well as people's awareness of energy saving and environmental protection, rooftop solar photovoltaic power generation because of its infinite, cleanliness and other advantages gradually into the people's vision, a lot of public buildings, enterprises, residential rooftops, etc. are installed on the “power station! Many public buildings, enterprises and residential rooftops have been installed with “power stations”, which can effectively alleviate the tension of electricity consumption and reduce the cost of electricity, and at the same time, also produce great environmental benefits. The use of idle resources on the roof of enterprises to achieve income generation, promote energy conservation and emission reduction and the development of green energy industry.

Second, policy support to increase the promotion of roof solar photovoltaic building integrated design

Rooftop solar photovoltaic power generation is to convert solar energy into electricity, with significant energy saving, environmental protection and economic benefits, is one of the highest quality green energy. Installed on the roofs of homes and factories, self-generation and self-consumption, excess power is then uploaded to the grid power generation model is known as distributed power generation.

In order to accelerate the construction and application of new rooftop solar energy systems, clear new civil building projects should make full use of building roofs, facades and other suitable site space configuration of solar photovoltaic systems. Actively carry out photovoltaic building integration design and construction, encourage the use of photovoltaic roofing materials, photovoltaic glass curtain wall and other building materials type photovoltaic components. New public buildings should give priority to the configuration of solar photovoltaic systems, to meet the requirements of renewable energy applications, its utilization in addition to the provisions of the relevant standards and norms, should also be in line with the new office buildings of state organs, government investment or government investment-based public buildings, solar photovoltaic systems, the consumption of the total energy consumption of the project accounted for the proportion of not less than 12%; other public buildings, solar photovoltaic systems, the proportion of the total energy consumption of the project. For other public buildings, the proportion of solar photovoltaic system consumption in the total energy consumption of the project shall not be less than 10%.
