Ascent Solar Technologies Inc. (NASDAQ: ASTI) is shifting its focus from space to the seas, aiming to capture a share of the marine solar panel market projected to reach $5 billion by 2035, growing at a CAGR of 13.1% over 2025-2035. The company, known for developing featherweight, flexible, and durable CIGS thin-film photovoltaic (PV) cells, reports that its marine-ready solar panels are not only saltwater-resistant but also cost-effective. With partners including NASA’s Marshall Space Flight Center and the Georgia Institute of Technology, Ascent is increasingly expanding into marine applications.
Ascent Solar’s CIGS solar cells are gaining traction in the marine industry due to their lightweight, flexibility, and strong performance in low light. These attributes make them suitable for space exploration, drones, and surface and underwater vehicles, both military and commercial. The company claims a competitive edge through its ability to deliver solar arrays in six to eight weeks, significantly faster than rivals with lead times of nine to 12 months. Ascent Solar believes this manufacturing speed will be a major advantage for OEM boatbuilders and integrators requiring responsive supply chains.
The company already has a history in the marine market, having delivered modules for testing in saltwater and underwater monitoring applications. These demonstrate the potential of remote systems under extreme conditions, critical for ocean monitoring, offshore platforms, and long-range vessels. Their performance in low light and extreme temperatures suits unpredictable marine environments. Additionally, Ascent Solar’s patented Monolithic Integration (MI) technology allows panels to continue generating power even if partially damaged or punctured, a key feature for solar-powered boats in the deep ocean where traditional panels would fail if damaged by waves or heavy winds.
Ascent Solar is becoming more active in the maritime market. An ocean monitoring company is currently testing the functionality and durability of Ascent’s PVs in aquatic terrestrial applications to enable persistent equipment operation. Meanwhile, Georgia Tech is integrating solar arrays directly into the wings of unmanned aerial vehicles (UAVs) designed for ocean monitoring. These solar-powered seaplanes are being developed for persistent, long-range maritime surveillance. Ascent Solar sees its panels as a solution for persistent ocean buoys, sensors, autonomous underwater vehicle (AUV) surface charging, and electric boat hulls. Beyond traditional surface PVs, the company’s tech has drawn interest from developers of autonomous vehicles, a niche but rapidly expanding area within the broader marine solar market.
By combining rapid manufacturing with extreme durability, Ascent Solar is positioning itself at the helm of the next generation of green ships and applications. For more information, visit Ascent Solar's website.
