<p>Janta Power is pitching a vertical solar tower (seen above) configuration that fits inside the footprint of a conventional ground-mount but produces roughly 50% more energy. Commercial deployment is on the way, the Dallas-based developer says, having recently closed a $5.5 million seed round, led by MaC Venture Capital with participation from Collab Capital to scale manufacturing and deployment.</p>

<p>The funding comes as Janta begins pilot programs at major global airports through the Airports for Innovation (A4I) initiative, including Munich International Airport, Aena (operator of 70+ airports), and Dallas–Fort Worth International Airport. The company says demand is also emerging from data centers, EV charging hubs, telecom towers, universities, and industrial sites facing land or interconnection constraints.</p>

<p>Janta is branding this a &#8220;3D tower&#8221; to contrast it with the typical flat solar array. Janta’s tower stacks PV vertically in a patented geometry that the company says provides 3× the exposed solar surface area per footprint. The vertical format captures low-angle morning and evening light, producing a dual-peak curve that aligns more closely with load than single-axis tracker systems concentrated around noon.</p>

<ul class="wp-block-list">
<li>Capacity factor: ~32% (vs. ~22% for flat-panel ground-mount)</li>

<li>Land use: ~1/3 the land for equal nameplate</li>

<li>Modeled LCOE: as low as $0.05/kWh (vs. ~$0.15/kWh global avg)</li>

<li>Wind design: engineered for 110–170 mph survival loads</li>

<li>Civil scope: modular steel with helical or pier foundations, no major grading</li>
</ul>

<p>Janta positions the tower as a complement to conventional PV, not a replacement — the flatter, smoother generation profile reduces ramping stress and lowers reliance on peaker plants, particularly in grid-constrained markets.</p>

<p>Airports, telecom towers, logistics hubs, and data centers routinely face “gross siting asymmetry” — large power demand and limited available land. Vertical PV is one of a small set of architecture shifts available to increase MWh per acre without new right-of-way or structural retrofits.</p>

<p>Janta is competing with the status quo, but also <a href="https://solarbuildermag.com/featured/overview-of-the-dual-axis-solar-tracker-market/">dual-axis trackers</a>, which have a similar approach packing power density with height over width. With new capital in hand, Janta says U.S. manufacturing scale-up and additional commercial deployments are planned over the next 24 months.</p>
