Case Study: A Desert-based PV Power Plant in Northern China

2024-12-31

A 250 MW PV plant in Northern China spans 10,000 acres and houses over 500,000 panels. The plant is located in harsh environments like deserts and coal-mining subsidence areas, where high winds and sandstorms pose significant cleaning challenges.

Challenges:

  • Challenging Geographic Conditions Hindering Manual Cleaning:Located in areas with complex terrains, extreme surface temperatures, and frequent sandstorms, manually cleaning solar panels is exceptionally difficult. Traditional methods require workers to operate under harsh conditions, leading to inefficiency and significant safety risks.

  • High Cleaning Frequency and Maintenance Costs:Desert regions accumulate heavy dust layers on solar panels, significantly blocking sunlight absorption and reducing power generation efficiency. Regular and frequent cleaning is necessary to maintain optimal performance. However, this demand for frequent manual cleaning results in high labor and costs. Additionally, manual cleaning often requires halting operations, further impacting economic returns.

  • Inconsistent Cleaning Results:Manual operations often fail to ensure uniform cleaning quality across all solar panels, leaving some areas unattended and leading to inconsistent results that hinder the overall efficiency of the solar farm.

  • Limited Stability of Traditional Cleaning Equipment:Conventional aerial and ground-based cleaning systems struggle with stability in windy and sandy environments, preventing efficient and safe cleaning operations.

Solutions

To address these challenges, Wisson Robotics developed a custom solar panel cleaning solution centered around the Orion AP30-P2 Pliabot® Aerial High-pressure Cleaning System. Tailored for desert conditions, the solution includes adjustable nozzles to optimize cleaning for varying dust coverage levels.
The Orion AP30-P2 leverages Pliabot Technology to deliver multi-angle, high-pressure aerial cleaning.
