At the Hengdian Mingtai 500MW photovoltaic power generation project in Ertai Town, Zhangbei County, the photovoltaic industry is booming, but the power station faces severe operational and maintenance challenges. The power station covers a vast area and houses a vast number of photovoltaic panels. Located in a windy, sandy, and rain-scarce region, the panels accumulate dust and dirt, including bird droppings. This severely impacts their light transmittance, reducing power generation efficiency by approximately 20%. Manual cleaning, previously relied on, only allowed each person to clean approximately 300 square meters per day, resulting in extremely low efficiency and high labor costs, reaching approximately 300 yuan per person per day. Furthermore, working across the vast, complex terrain of the photovoltaic arrays creates the potential for safety accidents with even the slightest carelessness.

After extensive research and comparison, the power plant decided to introduce the Xiangyangtian X8 remote-controlled crawler photovoltaic cleaning robot. Since its launch, it has demonstrated remarkable results. Its extra-wide 1.8-meter brush head increases the area covered in a single cleaning by 50% compared to conventional equipment. Its dual front and rear brushes (or front brush + rear water-spraying scraper) deliver exceptional cleaning capabilities. In heavily polluted areas, it can easily clean over 2 megawatts (2MW) of power per day. Manual cleaning of an area previously took 10 days, but now the X8 takes only 3, significantly reducing cleaning time. Its unique patented “Water Curtain Quick Cleaning” technology, using a multi-point fan-shaped spray from the front brush head to create a powerful water curtain, effectively eliminates secondary contamination, ensures effective cleaning of photovoltaic panels, and increases power generation efficiency by an average of over 15%.

The X8’s tracked chassis and exceptionally wide 70cm horizontal span capability enable stable operation in all conditions, ensuring comprehensive cleaning operations. For safety, four high-precision sensors on the front and rear of the robot form an intelligent anti-fall system. When the robot reaches the edge of a panel, it automatically applies emergency braking, illuminates a warning light on the remote control, and allows only reverse travel, eliminating the risk of falls. If the robot accidentally slips or is dragged, causing the cleaning route to deviate, it can quickly and autonomously correct itself and continue cleaning on the intended route. This reduces the need for remote control adjustments compared to conventional products, making it easier to use. Its intelligent control greatly facilitates operations and maintenance personnel. Its proprietary remote control boasts a battery life of up to 30 hours and features a built-in anti-interference chip. Even in complex electromagnetic environments like power plants and high-voltage power lines, it maintains stable, zero-delay control within a range of 100 meters, while also clearly displaying the battery status. The device’s intelligent path planning system can autonomously generate an efficient zigzag path. The cruise control function frees up manpower, and the automatic deviation correction function allows the robot to quickly and autonomously return to the preset route in the event of slippage or external force deviation, reducing manual intervention and improving operational efficiency and stability.

From a cost perspective, the X8’s efficient operation reduces labor costs by 60% compared to traditional manual cleaning. Its water-saving design and low maintenance requirements further reduce operating costs. The photovoltaic power station’s operations and maintenance manager commented, “The Xiangyangtian X8 has revolutionized our power station’s cleaning methods. It’s efficient, intelligent, safe, and reliable, resolving long-standing cleaning challenges. The increased power generation efficiency and reduced costs have made us truly appreciate the product’s value and give us confidence in future cooperation.” The successful implementation of the Xiangyangtian X8 at the Hengdian Mingtai Photovoltaic Power Station in Ertai Town, Zhangbei County, demonstrates its superior performance in photovoltaic cleaning, providing an efficient, safe, and economical solution for photovoltaic power station operations and maintenance.
