On April 8, Zhu Guoqiang, deputy chief engineer of the Beijing Capital New Pavilion Construction Project Owners Committee, revealed the mystery of this energy-saving demonstration project at the Olympic venue .
Even if it is cloudy and rainy, it can still generate electricity. Solar panels can absorb invisible light.
On the morning of the 8th, a long-awaited spring rain seemed to arrive. Deliberately making things difficult for solar installations. "On rainy or snowy days like today, even if there is no sunshine, the photovoltaic power generation device on the roof can still generate electricity." Zhu Guoqiang's response was unexpected.
Zhu Guoqiang said: "Usually, solar power generation devices absorb solar energy using the part of visible sunlight, which is the sunlight thatpeople feel sunny and cloudy days. This part of the light is greatly affected by the weather. And Shoubo solar panel can absorb the full spectrum of energy from the sun, which includes the visible light part like red, orange, yellow, green, blue and violet, and the part of the invisible light such as ultraviolet. and infrared rays."
"All-weather solar power devices are more efficient than conventional solar power devices. Devices that absorb visible light emit higher amounts of electricity and are basically unaffected by weather conditions. "Zhu Guoqiang said that the power generation on cloudy days is only 8% lower than that on sunny days.
Flat-mounted solar panels change the traditional diagonal support method

On the roof of the new building of the'Beijing Expo, in addition to the glass ceiling that collects the skylight and the top of the multifunctional hall vault, there is also The rest of the building was covered with dark brown solar panels.
Zhu Guoqiang explained that if the solar panels are supported diagonally on the roof, it will destroy the appearance and shape of the entire building. In addition, in the original architectural design of Shoubo, there was no design for the structure and load of installing solar panels on the roof, nor any design for the contacts of the brackets for installing solar panels. In order not to destroy the light and transparent artistic style of the decorative roof, the responsible departments finally decided to install the solar panels on the roof.
