Ascent Solar Technologies Inc. (NASDAQ: ASTI) is positioning itself to capture a share of the rapidly growing marine solar panel market, which is projected to reach $5 billion by 2035 with a compound annual growth rate of 13.1% from 2025 to 2035. The company, known for its featherweight, flexible, and durable CIGS thin-film photovoltaic (PV) panels, reports that its marine-ready solar panels are not only resistant to saltwater but also cost-effective.
Ascent Solar’s CIGS solar cells are gaining traction in the marine industry due to their light weight and flexibility. They perform well in low light, making them suitable for space exploration, drones, and surface and underwater vehicles, both military and commercial. The company claims a competitive edge by delivering solar arrays in six to eight weeks, significantly faster than rivals that have lead times of nine to 12 months. This rapid manufacturing capability is expected to 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 for underwater monitoring applications. These modules demonstrate the potential of remote systems under extreme conditions, which is critical for ocean monitoring, offshore platforms, and long-range vessels. 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 technology 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 to be at the helm of the next generation of green ships and applications. To learn more about Ascent, click here. Featured image from Shutterstock.
