Executive summary
robotic solar panel cleaning Maharashtra. The 75 MW ground-mount solar project in Yavatmal, Bansi, faced many operational hurdles. The local environment is quite intense. Road grit and agricultural dust constantly cover the panels. Local humidity cycles also change how dirt sticks to the surface. These factors create heavy and uneven soiling patterns across the entire solar array.
For O&M teams, this caused unpredictable power losses at the string level. Managing water logistics was also a major problem. Scheduling night crews often conflicted with other site work. These conflicts included vegetation control and civil maintenance windows. Furthermore, supervisors lacked reliable proof of cleaning. They could not verify which specific blocks were actually cleaned during each cycle.
To solve these problems, Taypro deployed two HELYX semi-automatic robots. The site uses a Capex procurement model. This setup allows for scheduled dry cleaning cycles. These cycles typically occur 3 to 10 times per month. The frequency depends on the local weather and dust levels. The site uses the NECTYR fleet operations portal for total oversight. This tool allows supervisors to verify cleaning progress in real time.
This robotic solar panel cleaning Maharashtra deployment has delivered great results. The site has successfully recovered 75 MWh/yr in additional generation. It has also saved 280,000 litres of water annually. These improvements have significantly optimized all site maintenance workflows.
Environment and soiling at Yavatmal, Bansi
Managing uneven string-level soiling patterns in Yavatmal
The 75 MW ground-mount facility in Yavatmal, Bansi, sits in a complex environment. This region in Maharashtra has a unique agricultural landscape. The site faces a constant cycle of airborne agricultural dust. Fine road grit also settles on the panels. These particles do not spread evenly across the array. They create uneven soiling patterns at the string level.
Persistent humidity cycles make the problem worse. Moisture causes the dust and grit to bond to the module surface. This creates a stubborn film on the glass. This film significantly blocks light absorption. As a result, the energy output of specific strings drops unexpectedly. These patterns are very hard to manage with traditional methods.
Because these deposits settle inconsistently, O&M teams had many difficulties. They struggled to identify which modules needed immediate cleaning. This unpredictability hurt the overall site performance. It also created logistical conflicts. Teams had to balance water-based cleaning with vegetation and civil works. The lack of granular data was a major weakness. Supervisors could not verify which strings were actually cleaned during manual cycles.
To overcome these challenges, the site moved to a new strategy. They adopted robotic solar panel cleaning Maharashtra using two HELYX semi-automatic robots. This approach allows for targeted and waterless cleaning. The robots address heavy soiling exactly where it accumulates. By scheduling 3 to 10 dry cycles per month, the site maintains panel transparency. This happens regardless of shifts in the local environment. The NECTYR fleet portal provides the necessary proof of cleaning. This ensures every block is addressed efficiently. It also prevents competition for limited water resources or site access windows.
O&M before Taypro
Managing uneven string-level soiling patterns in Yavatmal
Before the robotic deployment, the 75 MW facility faced major maintenance issues. The agricultural landscape of Maharashtra caused constant soiling. Airborne dust and road grit were the primary culprits. These particles were often bonded to the modules by humidity cycles. This created a heavy grime that lowered solar energy production.
The management of these soiling patterns was very difficult. O&M teams could not easily track which modules were dirty. This made it hard to plan effective cleaning schedules. The process was often reactive rather than proactive. This unpredictability led to significant performance gaps across the plant. It also made the maintenance budget harder to manage.
Logistics were another massive hurdle for the site. Water-based cleaning required significant amounts of water. Moving water across a 75 MW site is a complex task. It often clashed with other essential site activities. For example, vegetation management and civil works required the same access roads. Night crew schedules also conflicted with other maintenance windows. This created a chaotic environment for site supervisors.
The most critical issue was a lack of accountability. Supervisors had no way to prove that cleaning was done correctly. They lacked granular data for each specific string or block. This made it impossible to verify the ROI of manual cleaning efforts. The site needed a more disciplined and verifiable method. They needed a way to clean panels without the logistical burden of water and manual labor.
Fleet and deployment at 75 MW
Deployment and fleet strategy for the 75 MW Yavatmal array
The 75 MW ground-mount project in Bansi, Maharashtra, uses a Capex model. This model integrates advanced robotic cleaning technology into the site's long-term assets. The fleet consists of two HELYX semi-automatic robots. These units are specifically chosen for the soil type in Yavatmal. They address the unique challenges of agricultural and road dust.
This deployment focuses on high efficiency. It also aims to remove logistical bottlenecks. The site uses a semi-automatic cleaning approach. This provides great operational flexibility. By using the HELYX system, the site avoids heavy water usage. This is a key benefit for the local environment. It also prevents cleaning from interfering with vegetation and civil works.
The transition to robotics supports a sustainable cleaning cadence. The site saves 280,000 litres of water every year. This is a massive improvement for a large-scale utility plant. The strategic placement of the robots is also vital. It ensures that the most heavily impacted strings get consistent attention. This prevents large-scale energy losses due to localized grime.
Commissioning this fleet required a focus on real data. The site integrated the NECTYR operations portal. This allows managers to track robot performance across the entire 75 MW capacity. This digital oversight solves the old problem of "proof of cleaning." Every cleaning cycle is now logged and verified. This automation recovers 75 MWh of extra energy every year. This directly offsets the losses caused by local dust and grit.

Operations and monitoring
Optimizing cleaning cadences through inspection-led accountability
The Bansi facility had to move away from old manual labor models. These old models were often opaque and unreliable. Previously, supervisors did not know which strings were cleaned. The new semi-automatic fleet changes this completely. The project has moved from manual uncertainty to a structured program. This program is driven by inspections and real data.
The new operational framework is very disciplined. It uses a cadence of 3 to 10 dry cleaning cycles per month. This schedule is based on local dust and grit patterns. It ensures that cleaning intensity matches the actual soiling rates. The NECTYR portal handles all the scheduling. Every row transition and cleaning event is logged. Each action is also time-stamped for complete accuracy.
This system gives asset managers full visibility. They can confirm that all cleaning targets are met. They no longer have to rely on the myth of daily washing. Not every module needs washing every day. Instead, the robots clean based on actual site needs. This prevents wasted effort and unnecessary robot wear.
The NECTYR integration also improves site safety. The team can implement wind holds and safety protocols. Robots remain docked during extreme weather events. This protects the equipment and the modules. Because the HELYX units follow a verified schedule, logistics are easier. Water and crew conflicts have been eliminated. This allows the plant to maintain steady power output. It effectively neutralizes the degradation caused by humidity and agricultural residues.
