Ascent Solar Technologies Inc. (NASDAQ: ASTI) is positioning itself as a key player in the marine solar panel market, which is projected to reach $5 billion by 2035, growing at a CAGR of 13.1% from 2025 to 2035. The company develops featherweight, flexible, and durable CIGS thin-film photovoltaic (PV) cells that are saltwater-resistant and cost-effective, making them suitable for marine environments. Ascent has partnerships with notable entities such as NASA’s Marshall Space Flight Center and the Georgia Institute of Technology, and is increasingly focusing on marine applications.
Ascent Solar’s CIGS solar cells are gaining traction in the marine industry due to their lightweight and flexible nature, as well as their performance in low light conditions. These attributes make them ideal for space exploration, drones, and surface and underwater vehicles, both military and commercial. A key competitive advantage for Ascent is its ability to deliver solar arrays in six to eight weeks, significantly faster than competitors who have lead times of nine to 12 months. This rapid manufacturing capability is a major benefit for OEM boatbuilders and integrators who require responsive supply chains.
The company has a history in the marine market, having delivered modules for testing in saltwater and for underwater monitoring applications. This experience demonstrates the potential of Ascent’s systems in extreme conditions, which is critical for ocean monitoring, offshore platforms, and long-range vessels. The panels’ performance in low light and extreme temperatures makes them suitable for unpredictable marine environments. Additionally, Ascent’s patented Monolithic Integration (MI) technology allows panels to continue generating power even if partially damaged or punctured, a crucial feature for solar-powered boats in the deep ocean where traditional panels would fail completely if damaged.
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, developing solar-powered seaplanes 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 technology has attracted 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 forefront of the next generation of green ships and applications. For more information, visit Ascent Solar’s website.
