The world's largest solar energy building, saving 2,640 tons of coal per year, was selected into junior high school textbooks

 1 solar panels plant

Dezhou, Shandong, is known as the “China Sun City”. In this city, the world solar landmark building, the Riyuetan Weipai Building, is currently the world's largest solar building with a total construction area of approximately 75,000 square meters. 

2 pv panels


This building combines the functions of display, scientific research, office, conference, training, hotel and other functions. It adopts the world's first combination of solar hot water supply, heating, refrigeration, photovoltaic power generation and building technology. It is currently the world's largest collection of solar thermal energy. High-rise public buildings integrating photovoltaic, building and energy conservation.

 3 photovoltaic panels

Riyuetan installed the world's largest solar air-conditioning system with a heat collection area of 9188.7 square meters, which is 60% more energy efficient than conventional heating and cooling methods. It can meet the cooling load of 45% of the 11-story building, and the contribution rate of solar heating in winter is over 60%. Through solar energy, its overall energy efficiency is 88%. It can save 2,640 tons of standard coal, save 6.6 million kWh per year, and reduce 8672 tons of pollutant emissions.

The original design of the Sun Moon Altar was inspired by the release of the heat of the sun, the sun of Enze, and the ancient Chinese timekeeping tool “Sunday”, which symbolizes the constant replacement of energy and time constraints. Her appearance is taken from the ancient Chinese pictograms "Day" and "Month", white architectural tones, using pure energy.

 5 solar system

In the top glass of the building, a block of black rectangular grids of 3.5-inch disk size is inlaid. These black squares are solar photovoltaic panels and LED lights.

 6 BIPV solar plants

The concept of energy conservation and environmental protection is infiltrated throughout the building, and the green design concept is incorporated into the construction. The steel used in the building is only 1% of the steel used in the nest. Advanced roof and wall insulation is 30% more energy efficient than national energy efficiency standards.
