Driven by the "dual carbon" goals, the installed capacity of photovoltaic power stations has soared, but the power generation efficiency loss caused by pollution such as dust shielding and bird droppings accumulation is as high as 15% to 30%. Although photovoltaic cleaning robots can solve cleaning problems, they have fallen into new predicaments due to traditional power supply methods - frequent battery replacement, manual plugging and unplugging for charging, and the risk of cable dragging have increased the operation and maintenance costs of rooftop power stations instead of decreasing. How can cleaning robots be made "self-sufficient" like photovoltaic panels? Qingdao WIRELESSPT Technology, with a dedicated wireless power supply network for photovoltaic scenarios, builds a closed-loop ecosystem of "power generation - power storage - power consumption", ushering in a zero-carbon future of unmanned operation and maintenance for rooftop power stations.

The predicament of traditional operation and maintenance: Every cable is a cost black hole

In distributed photovoltaic power stations, the power supply pain points of cleaning robots have been infinitely magnified:

- Wiring challenges: The roof is uneven in height and the components are densely arranged. Dragging wires for charging can easily scratch the photovoltaic panels, posing a risk of hidden cracks.

- Manual reliance: In outdoor scenarios, batteries need to be replaced or charged by plugging and unplugging regularly, and the safety risks increase sharply in high-temperature and high-altitude operations.

- Energy consumption: Traditional charging relies on mains electricity or diesel generators, which runs counter to the clean "zero-carbon" concept of photovoltaic power.

- Reduced efficiency: The average daily effective cleaning time of the robot is less than 4 hours, and the remaining battery power is often forced to interrupt the task and return to charge.

WIRELESSPT Wireless power supply Network: Enabling Cleaning Robots to "consume Their Own Electricity"

WIRELESSPT innovatively integrates photovoltaic power generation with magnetic coupling wireless transmission technology, launching the world's first wireless power supply system for photovoltaic scenarios and achieving three major breakthroughs:

1. Photovoltaic green power closed loop: Rooftop power stations are self-produced and self-used, with zero reliance on external energy sources

The system is directly connected to the DC side of the photovoltaic array, using redundant electrical energy to drive the wireless charging piles. The charging energy for the cleaning robot is 100% from solar energy.

It is equipped with an intelligent energy storage module, which automatically switches to energy storage power supply on rainy or cloudy days to ensure 7× 24-hour uninterrupted operation.

2. Contactless charging matrix: Full roof coverage, robots charge wherever they go

Embed the wireless charging transmission module into the photovoltaic bracket or the reserved slot on the roof, and flexibly arrange it according to the density of the cleaning path to form a "charging grid".

When the robot passes through the charging area, it automatically triggers a second-level recharge, extending the battery life for a single cleaning task to 8 hours and increasing the average daily effective operation time by 120%.

3. Minimalist operation and maintenance design: resistant to high temperatures, dust-proof, and requires no maintenance

The charging pile has an IP68 protection level, can withstand temperatures up to 85℃, is resistant to sand and dust erosion, and is not afraid of extreme outdoor climates.

The entire system has no exposed interfaces and requires no battery replacement. The frequency of manual maintenance has been reduced from an average of 4 times per month to once a year.

Empirical Case: How Does Wireless Power Supply Activate the Value of Power Stations

Shandong 20MW commercial and industrial rooftop power Station: Equipped with 12 cleaning robots and 36 wireless charging points, the annual power generation increased by 18%, saving 370,000 yuan in operation and maintenance costs, with an investment payback period of only 1.2 years.

The ground-mounted power station in the Gobi Desert of Qinghai Province: The wireless charging piles have been operating continuously for three years without any faults in the sandstorm scenario, and the robot cleaning efficiency has been increased by three times compared with the traditional mode.
