Description

Solar scaffolding

The new model relates to a co-construction facility for rural power and electricity, in particular to a solar shed.

With the global emphasis on environmental protection, green energy has become one of Taiwan's energy development goals. However, due to the limited land area in Taiwan, the land demand for the development of green energy will inevitably conflict with agricultural development. Therefore, the development of co-construction facilities for agriculture and green energy (i.e., co-construction facilities for agricultural power) that can share land is the Taiwan Green Can be one of the primary research goals.

In rural power co-construction facilities (such as solar photovoltaics), the shading rate and abnormal light transmittance caused by the installation of solar panels will cause changes in the micro-meteorological environment such as light, temperature, humidity, wind speed and wind direction inside the facility And mutation, and further affect the soil and biological environment inside the facility, and ultimately affect the production quality of cultivated crops. When the agricultural power co-construction facility has a problem of high solar panel shading rate, and the excessively high shading rate causes insufficient light, the agricultural power co-construction facility will produce abnormal physiological and metabolic functions of crops, growth speed will be inhibited, growth retardation, and fruit size Restrictions and other issues, thereby significantly reducing the quality of crop production.

In order to allow crops to get full sunlight, the current solutions are: heighten the solar panels to increase the lateral light, or install movable solar panels. However, the former needs to increase the height of the scaffold and the scaffold must be increased. The strength of the steel structure can support the increased structure, and the latter must be equipped with a moving track and an electric control module, both of which will greatly increase the cost.
