Executive summary
The 3.8 MW Hirasar facility is located in Maharashtra. This solar plant faced many major operational problems. These issues came from uneven soiling patterns on the modules. Agricultural dust from nearby farms was a big factor. Road grit from site traffic also caused buildup. Local humidity cycles made the dust even harder to manage. These factors created unpredictable accumulation across different solar strings. Managing manual cleaning was also very difficult. Night crews and vegetation management tasks often competed for time. Supervisors also lacked clear proof of cleaning. They could not easily verify if every block was cleaned. This created large visibility gaps in plant maintenance.
Taypro solved these inefficiencies with an automated solution. We deployed a fleet of four GLYDE autonomous robots. These robots perform daily waterless cleaning cycles. The system works with the NECTYR monitoring platform. This shift replaced manual logistics with automated schedules. The deployment is fully verifiable through digital logs. This change added 3.8 MWh of extra generation every year. It also saved 14,000 litres of water per year. The plant now maintains consistent energy output despite the harsh environment.
Environment and soiling at Hirasar
Addressing site-specific soiling at Hirasar
The 3.8 MW Hirasar project operates in a unique environment. Agricultural dust from nearby farmland is a constant issue. Road grit from site traffic also settles on the panels. This mixture creates a complex coating on the photovoltaic modules. Local humidity cycles change how this dust behaves. The dust can harden when the weather shifts between moisture and heat. These conditions cause uneven soiling patterns across the site. Some strings experience much higher losses than others. This happens because some strings are closer to field boundaries or access roads.
Traditional manual O&M could not handle this variability. Night crews could not easily find which strings needed priority cleaning. Several key factors caused these persistent generation gaps:
- Micro-climate impact: Fluctuating humidity levels turn mixed dust and grit into a hard layer. This makes deposits difficult to remove without regular cleaning.
- Logistics friction: Water supply and night shifts often clashed with other site needs. These tasks included vegetation control and civil maintenance.
- Lack of verification: Supervisors did not have per-block data. They could not confirm if every string was actually cleaned.
O&M before Taypro
Overcoming Operational Constraints at the 3.8 MW Hirasar Site
Before the Taypro GLYDE system, Hirasar relied on manual labor. These methods struggled to keep up with the local soiling. Agricultural dust and road grit were very common. Frequent humidity cycles made the dust stick to the panels. This created a hardened layer that manual crews could not remove consistently. Because of this, the plant saw uneven soiling. This led to significant energy losses across the 3.8 MW site.
The O&M process also faced scheduling hurdles. Coordinating water logistics was a major challenge. Managing night cleaning crews also created bottlenecks. These issues often interfered with vegetation management and civil repairs. Furthermore, supervisors lacked transparent data. They had no per-block proof of cleaning completion. This led to audit gaps. It also caused unpredictable energy yields for the plant owners.
Fleet and deployment at 3.8 MW
Fleet and deployment at 3.8 MW
The Hirasar plant uses a Capex model to secure its energy yields. We deployed a fleet of four GLYDE robots to ensure stability. This scale provides full coverage for the entire site. The robots perform daily autonomous dry cleaning cycles. This method helps manage the impact of dust and road grit. Daily cleaning prevents the dirt from hardening on the modules.
The commissioning process was very carefully planned. We focused on seamless integration with existing site infrastructure. This ensured the robots did not interfere with vegetation or civil maintenance. By using a fixed robotic fleet, the site removed many manual hurdles. The project no longer struggles with night shift logistics. It also no longer depends on daily water deliveries.
- System choice: Four GLYDE units provide total coverage. They ensure daily and repeatable cleaning for every solar string.
- Procurement: The Capex model allows for long-term hardware ownership. This protects the site against rising labor and water costs.
- Operational proof: The NECTYR platform provides automated verification. Managers receive per-block data for every single cycle.
- Resource optimization: The system saves thousands of litres of water annually. It also maintains very high cleaning efficiency.
Operations and monitoring
Optimizing daily cleaning cycles and verifiable maintenance
The Hirasar facility replaced manual crews with four GLYDE robots. This transition moved the site to daily waterless cleaning. These cycles remove dust and grit before they become stubborn layers. The robots use patented dual-pass microfiber technology. This technology is highly effective and very consistent. It cleans the modules without needing any water. This also removes the need for complex night-shift labor management.
Operational accountability is now managed through the NECTYR platform. This software gives supervisors real-time proof of work. They can see data for every completed cycle at the block level. This eliminates the audit gaps found in manual cleaning programs. The system also features automated wind holds. These sensors pause the robots during extreme weather. This ensures the equipment stays safe during high winds.
- Daily cadence: GLYDE robots execute waterless cleaning every day. This prevents the buildup of agricultural dust.
- Accountability: NECTYR provides granular data logs. Managers can verify cleaning across the whole 3.8 MW site.
- Resource savings: Daily operation eliminates the need for water logistics. It also removes the need for manual scheduling.
- Autonomous safety: Integrated wind sensors trigger automatic protocols. This protects the robotic fleet during heavy weather.
Results and impact
Results and impact of autonomous cleaning at Hirasar
The four GLYDE robots have changed the O&M profile at Hirasar. The plant moved from manual methods to a daily waterless schedule. This shift helps manage the impact of road grit and dust. The autonomous approach ensures consistent generation recovery each year. Energy yields remain high despite the local humidity. The site is now more resilient to environmental changes.
The project also delivers great resource efficiency. The fleet has ended the need for complex water logistics. This has resulted in massive water savings every year. NECTYR provides the oversight needed to verify all work. Site managers can now confirm that every string is clean. This reduces the site's dependency on manual labor crews.
- Generation Recovery: The daily cleaning cycle recoups significant energy output every year.
- Resource Efficiency: The waterless GLYDE system preserves thousands of litres of water annually.
- Verified Maintenance: NECTYR provides per-block accountability. This replaces manual oversight with precise digital logs.
- Operational Stability: Automation reduces risks from labor availability. It also solves night-crew scheduling issues in Maharashtra.
