Planted has raised $31.8 million in a funding round, planning to use the capital to expand its robotic fleet and introduce a new generation of equipment for solar power plant construction. Planted develops systems that combine project planning software, terrain-following solar arrays, energy storage and field robotics. The company says its technology is designed to automate parts of solar construction and enable projects on land that conventional tracker systems may not accommodate.
According to Planted, its solar arrays can be installed on land with slopes of as much as 27% without grading and can produce twice the energy per acre compared with conventional designs. The company also says its approach can reduce construction timelines by simplifying array designs and automating field work.
Planted cited a recent 28-megawatt behind-the-meter project serving a neocloud data center that reached power 10 months after the initial customer contact. Field construction was completed in less than three months, according to the company.
The company has also completed Bowes Solar, an 11-megawatt project in Illinois for Cultivate Power. Its next planned project is Aligned Climate Capital’s Armoracia development, which Planted said has been redesigned to occupy 16 acres, 10 fewer than originally planned. The revised design proceeded through local review after an earlier layout was rejected.
Planted deployed more than 10 megawatts of capacity in 2025 and expects to reach 100 megawatts in 2026. The company reports a project pipeline exceeding 20 gigawatts.
The new funding will also support the introduction of Sage, Planted’s next-generation construction robot, which is scheduled to enter field operations in late 2026. The company says Sage will more than double field productivity compared with its existing robotic fleet as it works toward a longer-term target of increasing field crew output tenfold.
Planted said its current robotic fleet is fully committed through 2027. The company plans to increase deployment capacity by manufacturing additional Sage units and is taking reservations for projects in 2028, while additional 2027 capacity will be allocated as new robots enter service.
“The way to close that gap is to turn the construction of a power plant into a manufacturing problem: building robots and deployment systems, not just projects,” Planted CEO Eric Brown said. “We have robots in the field proving the model works today. This round is how we scale it.”
Planted serves solar developers, independent power producers, data center operators and other large electricity users. Beginning in 2027, it plans to offer what it calls “powered land,” combining development sites with on-site power generation and compact project footprints.
The company is also expanding hiring in robotics, hardware, commercial operations and field operations in Oakland and at project locations across the United States.
