Janta Power Raises $5.5M for 3D Solar Towers

• Janta Power raises $5.5M to scale 3D solar towers, boosting power density and slashing land use for data centers, EV hubs, and industrial sites seeking cheaper, cleaner, round-the-clock energy.

Janta Power, a U.S. developer of three-dimensional solar tower systems, raised $5.5 million (€4.74 million) in a seed round to accelerate commercialization of its patented technology. The funding is aimed at scaling deployment and moving the company toward broader market adoption.

The company plans to target high-demand energy users, including data centers, EV charging hubs, telecom towers, universities, and industrial sites. Janta Power’s 3D solar towers are designed to boost power density and reduce land use compared with conventional flat-panel arrays, positioning the startup to serve space-constrained and round-the-clock operations seeking to cut energy costs and emissions.

How do Janta’s 3D solar towers increase power density and support 24/7 operations?

• Multi-surface geometry packs PV on vertical and angled faces, harvesting from many sun angles to deliver more kWh per square meter of ground than flat arrays
  
• Bifacial modules on tower facets capture both direct and reflected light, boosting yield without expanding the footprint
  
• Vertical east–west faces pull in strong morning and late-afternoon irradiance, flattening the production curve and lifting daily energy per area
  
• Reduced row spacing and minimal self-shading increase the effective packing factor, raising site-level power density on constrained parcels
  
• Light-colored ground treatments and integrated reflectors increase albedo to the tower’s lower facets, further lifting output per footprint
  
• Stack-and-rise design elevates modules into cleaner, cooler airflow; convective cooling improves module efficiency and sustains higher power density
  
• Height mitigates soiling, snow cover, and obstructions, preserving capacity on small sites where ground-mounted arrays underperform
  
• Distributed MPPT/microinverters per facet optimize each plane independently, maximizing total harvest from mixed orientations
  
• Oversized daytime production relative to footprint enables right-sized DC-coupled batteries to be charged for night-time supply
  
• Integrated storage and energy management software shape output—peak-shaving by day, firming and dispatch through evening and night for 24/7 loads
  
• Fast-response power electronics provide UPS-like ride-through for momentary grid events, supporting always-on operations
  
• Optional hybrids (e.g., existing gensets or fuel cells) tie into the same DC/AC bus, creating a resilient microgrid that delivers round-the-clock power even in low-solar periods
