Janta Power Raises $5.5M Seed Round Led By MaC Venture Capital To Commercialize High-Density 3D Solar Towers

Janta Power, a leading developer of innovative three-dimensional solar tower systems, has successfully closed a $5.5 million seed funding round led by MaC Venture Capital, with participation from Collab Capital. The investment will accelerate the commercialization of Janta’s patented high-density 3D photovoltaic tower technology, supporting product scale-up and deployment across a variety of sectors, including data centers, EV charging hubs, telecom towers, universities, and industrial facilities.

Janta’s vertical solar towers are designed to generate approximately 50% more energy than traditional flat-panel systems while using only one-third of the land area, addressing the energy-density and siting limitations of conventional solar. The towers’ stacked vertical design captures low-angle morning and evening sunlight, producing a dual-peak power curve that better matches real energy demand throughout the day. By increasing solar surface area exposure roughly threefold compared to flat arrays within the same footprint, Janta’s towers maximize energy output while minimizing land use.

Pilot programs are already underway with major global airports, including Munich International Airport, Aena (which operates over 70 airports worldwide), and Dallas–Fort Worth International Airport, as part of the Airports for Innovation (A4I) initiative. These pilots aim to demonstrate the system’s efficiency and reliability in high-demand environments.

Janta’s technology achieves a typical capacity factor of approximately 32%, compared with around 22% for traditional flat panels, thanks to active shading optimization and control software. Each tower is engineered to withstand winds from 110 to 170 mph and features steel construction with modular helical or pier foundations, eliminating the need for extensive site grading. Unlike single-axis trackers that concentrate output near midday, Janta’s 3D design delivers smoother energy output across the day, reducing ramp stress on grids and lowering reliance on peaker plants. This generation profile complements conventional solar and contributes to overall grid stability.

The company’s solar towers currently achieve a Levelized Cost of Energy (LCOE) as low as $0.05 per kilowatt-hour, significantly below the global average of approximately $0.15 per kilowatt-hour. With ongoing scaling and optimization of manufacturing and deployment processes, Janta Power aims to further reduce the LCOE in the coming years, offering a highly efficient and cost-effective solution for distributed renewable energy generation.
