The lifespan of a solar panel is typically around 25 years, depending on its build quality, workmanship, and installation location. If regular cleaning is not carried out during this period, the energy efficiency will decrease year by year. For Solar Power Plants (SPPs), regular cleaning is essential to maintain high efficiency. Solar panels use their surface to absorb heat and light, which is then converted into electricity. A dirty and dusty surface hinders the panel’s ability to generate power. For the panel to produce its nominal power, no dust, dirt, pollen, or other pollutants should stick to its surface. If not cleaned for an extended period, these pollutants can damage the panel.

To obtain maximum efficiency from the panels and prevent potential damage caused by dirt, periodic cleaning is required. During cleaning, deionized pure water should be used, and chemical cleaners or high-pressure water should be avoided. Also, it’s important not to step on the panels during cleaning. Microcracks caused by pressure can lead to water or other liquids entering the system, causing significant issues for the solar plant.
At Robsys, we develop Solar Power Plant (SPP) cleaning robots designed to increase energy efficiency and sustainability. We focus on creating innovative, functional, and technologically advanced robots with high capacity. Our Robsys RTM Series, YTM Series, and DTM Series solar panel cleaning robots offer effective solutions to improve the efficiency of sustainable energy sources.
The RTM series, our latest product developed through extensive R&D work, offers a cleaning capacity of 1-3 MW per day and is equipped with a remote control for easy operation. Its dual-direction system allows detailed cleaning without damaging the panels. Available in both battery-operated and electric models, it is suitable for cleaning solar panels on rooftops, ground installations, gardens, and various projects.
The YTM Series is designed for fixed projects. With its strong build and high cleaning capacity, it can clean up to 2-4 MW per day. The YTM models are equipped with remote control for ease of use and can operate in both wet and dry modes, making them suitable for all types of panels. Despite being designed for projects, they are lightweight and portable, weighing between 80-120 kg.
The DTM Series robots are designed for vertical working systems and are compatible with all solar panel systems. This model features a compact system integrated with pure water, making it ideal for cleaning solar panels installed on roofs, open fields, or in vertical configurations. The DTM series also operates in both wet and dry modes.
To get the most out of solar panels, a cleaning robot can help reduce costs and increase energy efficiency. The price of solar panel cleaning robots varies depending on the model and features. At Robsys, we continue to develop automated cleaning robots that improve energy efficiency and sustainability in solar power plants.

As a solar cleaning robotics engineer, I’ve seen firsthand how rapidly automation is transforming the maintenance of photovoltaic (PV) systems. Traditional methods—manual labor, water-intensive washing, and time-consuming processes—are no longer sustainable.Solar panel cleaning robots are now revolutionizing how we maintain PV installations. These high-tech devices offer efficient, automated, and water-free cleaning, helping solar systems maintain peak performance even in harsh, dusty environments. Whether you’re running a large solar farm or managing a rooftop array, robotic cleaning solutions are now essential tools for optimizing system output.
A solar panel cleaning robot is a fully automated device designed to clean solar panels without human intervention. Mounted directly on the panel surface, it uses electric motors, intelligent navigation systems, and sometimes AI-powered algorithms to detect and remove dust, debris, and bird droppings.
These robots eliminate the need for water in most cases, making them ideal for arid regions where water conservation is critical. Most are powered by rechargeable batteries and operate silently, ensuring minimal disruption to solar production.
Clean panels are efficient panels. According to the U.S. National Renewable Energy Laboratory (NREL), dirt and dust accumulation can lead to up to 30% energy loss if panels are not properly maintained.In places like Gujarat, India—known for its solar farms and dust-prone environment—this loss can be even more severe, especially during dry seasons. Traditional cleaning methods involve large volumes of water and significant labor costs. Moreover, these methods are not sustainable or scalable.
This is where automated robotic cleaning comes in. With precision cleaning and zero water consumption, robotic systems from companies like Solabot Technologies are now setting new standards in solar maintenance.
Robotic solar cleaners like those developed by Solabot utilize an advanced combination of:Solabot：
Soft, anti-scratch brushes
Sensor arrays to detect debris and panel layout
Autonomous navigation systems to move across rows
AI algorithms for optimized cleaning patterns
Battery-powered motors for quiet and efficient operation
These robots clean without causing micro-scratches, which can otherwise reduce panel efficiency over time. The entire process is automated and can be scheduled during non-peak hours or at night, ensuring maximum energy capture during the day.
Additionally, for large solar farms, these robots come with return-to-dock functionality, automatic recharging, and are designed to move over inter-row gaps using built-in bridge mechanisms.
There are generally two categories of solar cleaning robots available:
