The cleaning of solar panels on rooftops often encounters a very steep slope. If the design of the slope is to be washed with water, there is a risk of slipping. Moreover, without safety belts and ropes and other equipment, the cleaning difficulty is extremely high. Traditional manual cleaning may cause people to step on the photovoltaic panels .We will introduce three types of cleaning equipment to help you successfully solve the problem of high-altitude operation solar panel cleaning equipment. There are mainly three categories: automated robots, handheld cleaning brushes, and professional water automatic cleaning systems. Through the introduction of core features, main applicable scenarios, precautions and other aspects, you can choose the cleaning equipment that meets your needs.
1. Automated cleaning robot
1.1 Advantages
Automatic/semi-automatic operation saves time and effort, with high cleaning efficiency. The cleaning coverage rate of some models can reach over 98% – high safety, reducing the risk of manual high-altitude operations
1.2 Main Usage Scenarios
The owners of large and flat roofs are reluctant or find it inconvenient to work at heights
1.3 Precautions
The price is relatively high, and there are requirements for the flatness of the roof. Complex structures may affect operation.
2. Handheld electric cleaning brush
2.1 Advantages
It has a strong cleaning power, integrates water and brush, and is flexible to operate. The Angle of the brush head can be adjusted to fit solar panels of all angles, and the length of the telescopic rod can be adjusted to clean solar panels of different sizes.
2.2 Main Usage Scenarios
In situations where the amount of roof cleaning at home is moderate, the roof structure is relatively simple
2.3 Precautions
It is necessary to connect the water pipe and power supply
3. Automatic water cleaning system
3.1 Advantages
Unmanned operation liberates human resources. Once uniformly set, it can be started according to a plan (such as daily or weekly) or remotely with one click, completely eliminating the need for manual operation
The cleaning speed is fast and the coverage is wide. The automated system can complete the cleaning of the entire photovoltaic power station within tens of minutes, with an efficiency dozens or even hundreds of times that of manual cleaning. This is crucial for large-scale ground-mounted power stations at the megawatt level.
It can operate around the clock. Some systems are equipped with intelligent modes
3.2 Main Usage Scenarios
The solar panels are at a relatively high Angle. People cannot stand on the roof to clean the solar panels because the slope is very steep
3.3 Precautions
The roof must be perfectly matched with the layout, inclination, height and spacing of the array. Uneven roofs or complex array structures may require customized solutions. The load-bearing capacity of the roof must be evaluated, and anti-freezing measures should be taken in winter.
Cleaning and maintenance of rooftop solar panels
Choose to do it in the early morning, evening or on a cloudy day. Avoid working under the midday sun. The alternating cold and heat may cause the glass to crack, and the rapid evaporation of water leaves water stains. The cleaning frequency is 1-2 times a year in general areas, and once a quarter or more frequently in dusty, dry and bird-rich areas.
For stubborn bird droppings, do not scrape them hard. Soak them to soften before removing.
