The solar roof plan mobilizes the enthusiasm of all sectors of society through demonstration projects and promotes the implementation of relevant national policies. Strengthen the publicity of demonstration projects, expand the influence, improve market awareness, and form a good social atmosphere for developing solar photovoltaic products; Promote the implementation of policies such as on-grid tariff sharing, form a policy synergy, and amplify the policy effect; As an important content of building energy saving, photoelectric building has been actively promoted and applied in new buildings, energy-saving renovation of existing buildings and urban lighting.

Benefits: it can save electricity: the household photovoltaic power station generates electricity during the day, saving a payment item in the living expenses! Can make money: every power generation has a state subsidy of 0.42 yuan (and local subsidies in some places), and the inexhaustible electricity can also be sold to the State Grid. I used to spend money to buy electricity, but now I sell electricity to make money, and the yield is as high as 10%! Shading: When the photovoltaic module battery is laid on the roof in a large area, it can effectively reduce the indoor temperature of the building by 2-3℃, and indirectly save electricity for air conditioning. Emission reduction: A small distributed power generation system with an installed capacity of 3kW can generate 3650kW/year and 91250kW/year in 25 years, which is equivalent to saving 36.5t of standard coal, 94.9t of carbon dioxide and 0.8t of sulfur dioxide. The smog is so serious, really don't give yourself a chance to breathe fresh air?
