Not a maintenance service. Engineered yield optimisation infrastructure — built for MW and GW solar assets where every percentage point of soiling loss translates directly to revenue.
Avg. annual yield loss to soiling without intervention
Loss in desert & high-dust environments
Performance contract and insurance capability
Scale-ready deployment architecture
At residential or small commercial scale, soiling is a nuisance. At utility scale, it is a structural financial risk. A 2% soiling loss on a 100MW asset doesn't mean 2% less electricity - it means 2% of your entire contracted generation capacity, compounding daily, across an asset life of 25 to 30 years.
Lenders, EPCs, and asset managers working at MW and GW scale require cleaning programmes that are measurable, automated, and contractually defensible. Manual cleaning schedules with inconsistent coverage and no data integration are no longer fit for purpose.
Solagains systems are engineered specifically for industrial solar infrastructure — not adapted from smaller-scale products. That distinction matters at every level: mechanical design, software integration, spare parts availability, and long-term service commitments.
Brushes, drive systems and chassis components designed and tested for sustained operation across long array runs in high-dust, high-UV environments. Mean time between maintenance events measured in thousands of operating hours, not hundreds.
Operational across extreme temperature ranges — from sub-zero overnight conditions in highland sites to sustained 50°C+ surface temperatures in desert deployments. Electronics and actuation systems are specified accordingly, not rated for office environments.
Designed for the actual geometry of utility arrays — not adapted from rooftop products. Navigation, brush pressure management, and panel edge detection are calibrated for runs measured in hundreds of metres, not dozens.
Modular component design with a global spare parts programme. Field technicians can perform the majority of maintenance and repair tasks without specialist equipment or factory return. Designed for remote locations where downtime is not recoverable.

Utility-scale solar is built in places where the sun is strongest and the conditions are most demanding. Semi-arid scrubland. Coastal plains with saline air. Elevated sites with wind-driven grit and sand. Agricultural zones where irrigation spray and organic debris combine with heat to create fast-caking soiling layers.
Solagains systems are designed with these environments in mind. We work with operators during the site assessment phase to map soiling type, array layout, inter-row constraints, and access logistics — so the system specified is the one that will actually perform across the full operating cycle.
For projects with challenging terrain, mixed-tilt configurations, or legacy tracker hardware, our engineering team provides site-specific adaptation rather than requiring you to modify your infrastructure to suit the cleaning system.
Modbus, OPC-UA and REST API outputs. Compatible with all major SCADA platforms used in utility solar O&M.
Multi-site scheduling, live status monitoring, and centralised fault alerting from a single operator interface.
Continuous irradiance-comparative soiling rate data. Adaptive scheduling triggered by performance thresholds, not calendar intervals.
Full cycle-level records for lender reporting, PPA performance documentation, and O&M compliance requirements.
System availability commitments backed by service agreements — not aspirational figures. Spare parts programmes, response time SLAs, and preventive maintenance schedules are structured to meet the availability requirements of your O&M framework.
Contractual cleaning performance expressed in soiling loss reduction metrics — measurable by your monitoring systems and independently verifiable. Designed to support performance-linked O&M agreements and lender covenant compliance.
A 10 year cleaning contract requires a supply chain that will still be operating in year nine. Solagains provides documented parts lifecycle commitments and an escalation path for obsolescence management — so procurement and asset management teams have the certainty they need at investment committee.
Solagains engages at EPC and development stage, not just at O&M handover. Early engagement enables cleaning infrastructure to be integrated into civil design, water supply planning, and SCADA architecture from the outset — reducing retrofit costs and commissioning delays.
