According to the British "Daily Mail" and other media reports recently, the solar panels in the northern hemisphere want to absorb the most sunlight, traditionally installed to the south, but the Loughborough University study in the United Kingdom found that solar panels should be effective, must be based on the movement of the sun Adjust the direction instead of fixing it to the south. The study pointed out that designing a solar panel that can be moved flexibly, the solar panel is facing east in the morning, and the solar panel is moved westward at noon, and the efficiency can be limited. Experts stressed that solar panels do not have to be fixed to the south. According to the new installation method, when the electricity demand is noon and afternoon, the electricity generated in the morning can be continuously used, and the electricity generated by the solar panels in the afternoon can be used at night.
The study was led by Dr. Ralph Geshago of Loughborough University. Ralph said that it has always been believed that the orientation of the northern hemisphere solar panels is oriented towards the south and then according to seasonal changes. Adjust the offset angle of things, ** no more than 15 degrees. However, the ** study found that the installation orientation of the ** should be adjusted according to the change of the sun position during the day, rather than being fixed to the south. Ralph said that they calculated the movement of the sun in the Northern Hemisphere throughout the year, and found that the solar panels were installed in any direction, with the least amount of electricity, especially facing south. The amount is about 10% less than the annual installation.
Ralph said that he and his colleagues have made a flexible solar panel that is at an angle to the horizontal direction and that works from sunrise to sunset. At sunrise, the researchers placed the solar panels facing east, and as the direction of the sun changed, the amount of electricity generated continued to rise, reaching its peak at noon. After that, they artificially turned the solar panels and placed them in the west. At this time, the power generation will be lower than when facing the east. However, between 13 and 14 pm, there will be a new peak in power generation. Ralph said that during the day, the sun is moving westward and adjusting the direction of the solar panels at any time, which can ensure that the solar panels receive light during the day, thus increasing power generation.
Considering that it is too laborious to move the solar panels by humans alone, Ralph and his team are developing a solar bracket that can be adjusted independently. According to the design, the solar panels can be moved at a constant speed under the support of the mechanical support, about automatic at noon. Turn and face the West.
