What is the best solution to setting up PV projects in the hills?

2024-01-17

Yunnan Province, where there are numerous high hills, presents a number of challenges for PV hill projects due to the complex terrain. About 94% of Yunnan province is covered by plateaus and hills. With an annual sunshine rate exceeding 2000 hours, Yunnan Province enjoys abundant sunlight all year round. As it is situated on a plateau at low latitudes, a stepped terrain descends from north to south, displaying a northwest-high, southeast-low pattern. This topographical feature facilitates the efficient absorption and utilization of solar radiation. As shown by the relevant data, Yunnan Province's installed PV capacity surpassed the tens of million-kilowatt threshold in 2023, and the percentage of PV power generation has steadily increased.

 

 

With its adaptability to diverse terrains, DAS Solar's flexible bracket matches steep slopes, ravines, and other harsh topographies to address these challenges. In terms of spatial utilization, rational high-density arrangements of PV arrays maximize installed capacity per unit area by controlling interrow spacing effectively. In addition to conserving more than 25% of the land area, the orientation of the modules to the sunlight can be maximized, which further improves module generation efficiency.

 

The flexible bracket from DAS Solar can reach a height of 8-9m, with a span of up to 40m. The PV modules are supported by a cable truss structure, which resists external loads in the east-west direction. The distortion and deformation outside the plane of the modules are effectively suppressed by multiple transverse systems in the north-south direction. At the midpoint, a damping system is used to reduce deformation under wind suction, ensuring module safety. Under the PV module array, sufficient land utilization space is preserved, maximizing space utilization efficiency while increasing the power generation capacity of the PV plant.

 

 

Compared to traditional single-pillar supports, DAS Solar flexible brackets have a truss structure and support characteristics that reduce steel usage, lowering the overall cost of PV plants. Through the use of a sliding method during construction, potential hidden cracks in the installation process can be avoided and installation efficiency is significantly increased.

 

 

DAS Solar flexible bracket projects cover a variety of "photovoltaic +" application scenarios, including hills, deserts, fisheries agrivoltaics, agrivoltaics, and herbs-agrivoltaics. DAS Solar will leverage the core advantages of N-type modules and lightweight modules in the future to provide comprehensive solutions for full-scenarios and processes.
