Under the background of accelerated global energy transition, efficiency improvement and cost reduction of photovoltaic power generation have become the core objectives. Traditional fixed-mount PV systems are affected by changes in the sun’s altitude and azimuth angles, and are unable to make full use of the sun’s radiant energy. By adjusting the angle of PV modules in real time so that they are always perpendicular to the sun’s rays, solar tracking mounts can significantly increase power generation (10%-30% compared with fixed mounts), especially in high-latitude areas with abundant light resources, where the advantages are more obvious. The project aims to develop and promote efficient and reliable solar tracking bracket structures, break through the efficiency bottleneck of traditional brackets, and promote the development of the photovoltaic industry in the direction of intelligence and high efficiency.
(II) Project Objectives
Technical Objectives
Develop single-axis / dual-axis tracking bracket system, supporting multiple tracking modes such as flat single-axis, inclined single-axis, dual-axis, etc., which can be adapted to different latitudes, terrains and climatic conditions.
Improve tracking accuracy (error ≤0.5°) and reliability, achieve wind resistance ≥12 (wind speed ≥34m/s), salt spray corrosion resistance (more than 1,000 hours), and service life ≥25 years.
Integrate intelligent control system, support remote monitoring, fault warning and big data analysis, reduce operation and maintenance cost.
Project Objective
Construct [X] MW tracking bracket demonstration project, verify the power generation gain and stability of the system in actual scenarios, and increase the annual power generation by more than [X]% compared with that of fixed bracket.
Achieve [X]% cost reduction and [X]% installation efficiency improvement compared with similar products, and promote large-scale application.
Social Benefit Target
Reduce carbon emissions in the whole life cycle of the project, and reduce carbon dioxide emissions by about [X] tonnes per MW of tracking bracket project per year.
Provide high-efficiency photovoltaic solutions for high latitude, mountain, desert and other special scenarios, and help achieve the ‘double carbon’ goal.
