  "account": "Solar farms often face challenges related to land usage and permitting. In St. Louis, a zoning board rejected a design due to its sizable footprint. However, startup Planted aims to change this by using a digital twin and robots to build solar farms using less land. This approach allows a 40% reduction in land use while maintaining the same power output, enabling projects to move forward. Planted secured $31.8 million in funding to scale up, led by Piva Capital and RA Capital Management Planetary Health, with support from Google, Breakthrough Energy Ventures, Gigascale Capital, and Khosla Ventures. Founder Mike Schroepfer notes that the rising cost of solar installation is a significant factor, and Planted's method tackles this issue. Traditional solar farms use long racks that flatten the land, but Planted uses individual posts that adapt to the terrain, maximizing the use of each parcel. The company builds a virtual model of the site to plan panel placement, then uses robots to place each post precisely, akin to snapping Lego pieces together. This technique allows for installation on slopes up to 27% without grading, utilizing more of the land and reducing the overall footprint. Planted's approach streamlines the permitting process as well, as the reduced land requirement makes it easier to find suitable sites. One example is a developer planning a solar farm to support a data center, who initially faced challenges due to the layout not meeting new requirements. Planted redesigned the project, increasing energy production by 2.5 times. Another project involved a hyperscaler that initially faced a wetlands designation issue. Planted redesigned the solar farm to make use of the remaining buildable land, ensuring minimal environmental impact. With the new funding, Planted will expand its robot fleet, which is currently fully booked through next year. The newest model, called Sage, doubles the productivity of the current generation. Planted anticipates building 100 megawatts of solar in 2026, with over 20 gigawatts in pipeline. This fast-growing solar technology could significantly accelerate the adoption of clean energy in the U.S.",
  "summary": "Solar farms have a land problem. When a new project was planned in a St. Louis suburb, the county zoning board rejected the design, arguing that it took up too much space and sat too close to a neighboring subdivision. The developer then turned to a startup called Planted to rethink the plan using a digital twin and robots. The result: The project used 40% less land to produce the same amount of…",
