Cleaning, operation and maintenance of photovoltaic modulesimportance

Photovoltaic modules are very sensitive to temperature. Dirt such as dust accumulates on the module surface, which increases the heat transfer and thermal resistance of photovoltaic modules and becomes a thermal insulation layer, affecting heat dissipation.

Intelligent cleaning equipment has great advantages in the operation and maintenance of large-scale photovoltaic power stations. It is also a good helper of photovoltaic power stations. The operation and maintenance process of large-scale photovoltaic power stations should use intelligent cleaning robots and intelligent cleaning equipment to complete the requirements of high-precision cleaning of large-scale photovoltaic power stations.

Recently, our engineering team went to a technology company in Longhu District of Shantou City to install intelligent photovoltaic cleaning robots for it. The company has built distributed photovoltaic power stations on the roofs of production plants and office buildings. Nearly 10000 square meters of roofs are filled with dense photovoltaic panels. The positive source of photovoltaic energy continuously absorbs the hot sun energy and converts it into electric energy, Silently escort the power consumption of the enterprise.

Spontaneous self use, which not only makes full use of the idle roof of the enterprise, but also becomes the first choice for enterprises to increase revenue and reduce expenditure.

What is the effect of traditional manual cleaning?

Low efficiency and wear on the surface of photovoltaic modules
Low safety and high cleaning cost
Unable to better improve power generation
The light transmittance and service life of photovoltaic panels are affected to a certain extent.

Photovoltaic robot independently developed by our company

According to the characteristics of the roof distributed photovoltaic power generation project and the actual needs of the operation and maintenance of the roof photovoltaic power station, our company independently developed the portable photovoltaic cleaning robot, which solved the problems of low cleaning efficiency and high labor cost of most of the current roof distributed photovoltaic power stations.

We adopt single board modular design to adapt to the complex and changeable board group layout and convenient maintenance. It can be widely used in industrial and commercial roof photovoltaic power stations with less investment, which improves the cleaning efficiency of photovoltaic power station panels, improves the power generation of photovoltaic system and the overall income of photovoltaic power station.

Product features

1. 5g intelligent control: remote wechat applet control, marshalling and independent control, automatic cleaning time and cleaning mode can be set.
2. Self charging: with its own solar power supply system, it is convenient and efficient, and can last for 8 to 10 hours.
3. Light weight: the whole machine is about 23kg, which is more than 35% smaller than the weight of similar products, and it is convenient to carry.
4. Strong adaptability: it is suitable for all kinds of array arrangement, adapt to the ambient temperature of - 40 to + 70 ℃, and suitable for all kinds of power stations.

（2） Core features
5. Brush replacement in one minute: the modular brush disassembly and assembly structure is designed independently, which can replace the brush module in one minute and improve the maintenance efficiency.

7. Self sensing mode: open the cleaning mode intelligently in rainy days.
8. The length of the cleaning robot can be adjusted according to the size of different components, which is suitable for more application scenarios
（3） Other features
9. Superior performance: it adopts lithium battery and brushless motor, which is durable.
10. Efficient cleaning: special brush can clean more cleanly, and a single machine can clean 1.2mwp/day.
11. Automatic start and stop: automatic return, adaptive, and remote control.
12. Danger avoidance, automatic edge avoidance, automatic danger avoidance.
13. Integrated dry cleaning and water washing: meet the needs of different photovoltaic power stations.
14. High cost performance: the user's input cost is not high, and can realize rapid cost recovery by increasing power production

According to the introduction of authoritative institutions, at this stage, some enterprises have successively installed solar photovoltaic power stations on the roof in response to the national call. Photovoltaic power generation, as a green power with zero emission and zero pollution, vigorously promotes and uses photovoltaic power generation, which is of great significance to achieve China's "3060" carbon peak and carbon medium vision..

In the future, adhering to the development mission of "high efficiency and energy saving, let more people enjoy green energy", our company will strive to build the company into a respected excellent photovoltaic power generation enterprise based on the photovoltaic industry.
