US firm’s 3D solar towers generate 50% more energy than flat panels

Texas-based company Janta Power has developed patented three-dimensional (3D) solar towers that generate approximately 50% more energy than conventional flat-panel solar arrays. These vertical towers maximize space efficiency by fitting three times the solar surface area into one-third of the land required by traditional solar farms. The design captures low-angle sunlight throughout the day by automatically tracking the sun’s path, enabling extended and more consistent energy generation that better aligns with grid demand and reduces stress on the electrical grid. The towers achieve a capacity factor of about 32%, compared to roughly 22% for flat panels, aided by active shading optimization and control software. Janta Power recently secured $5.5 million in seed funding led by MaC Venture Capital to scale up manufacturing and commercialization. The technology is being piloted at major global airports such as Dallas–Fort Worth International, Munich International, and Aena-operated airports, demonstrating suitability for land-constrained, high-security environments. Constructed with steel and modular foundations, the towers
