Maximo Robotics says its solar-construction robots have completed more than 300,000 field tasks under performance-based robotics-as-a-service contracts. In its 29 October announcement, the company reported that crews working with Max 4.0 achieved 2.5 times their manual installation rate per person per shift hour. Current projects span six engineering, procurement and construction contractors, multiple project owners, and sites in California, Illinois, Kansas, Louisiana, New York, Texas and Washington.
Customers pay for completed tasks, tying the service’s revenue to installation throughput. Work delivered so far includes autonomous placement of heavy utility-scale photovoltaic modules onto mounting structures, with crews working alongside the robots. Contract expansion options include module attachment and field logistics. Primoris Services Corporation’s renewables business has helped integrate Maximo into field operations and refine installation workflows.
Max 4.0 combines three proprietary systems: Cortex, which handles perception and planning for construction tasks and mobility; Form, the robots and task-specific tooling built for field work; and IQ, which manages service performance, fleet analytics and operational feedback. Maximo says data from completed jobs feeds further model training and deployment improvements. The company is developing extensions into pick-and-place work, feeding and attaching, site logistics and clean-up.
The business was incubated by energy developer AES Corporation. In March 2026, four version 3.0 robots working alongside union technicians completed installation work representing 100MW of solar capacity at AES’s Bellefield complex in California. Maximo reported a technical rate above one module per minute and crew productivity of up to 24 modules per person per shift hour at that project, after scaling from an initial single-robot deployment.
For 2027, Maximo reports a late-stage pipeline representing demand for approximately three million additional construction tasks, equivalent to about 1.5GW of solar installation. That prospective workload is about ten times the cumulative completed-task milestone and accompanies the company’s expansion from early AES projects into services for third-party contractors.
