Xfloat and BASF Partner to Enhance Solar Resilience

Xfloat Ltd., a pioneer in floating solar technology, has entered into a partnership with BASF to enhance the durability and sustainability of floating photovoltaic (FPV) systems. The collaboration combines Xfloat’s innovative sun-tracking floating platforms (FPV-T) with BASF’s advanced light stabiliser solutions, aiming to deliver robust, high-performance solar systems for large-scale global deployment.

Working closely together, Xfloat Ltd. And BASF has incorporated Tinuvin® 2730 ED, BASF's proprietary light stabilisation solution, into Xfloat’s HDPE float design to protect the material from long-term degradation. By integrating this additive into its high-density polyethylene (HDPE) floats, Xfloat enhances resistance to harsh environmental conditions, enabling a service life of more than 30 years in line with the expected lifespan of solar modules. The improved durability helps minimise maintenance and replacement requirements, ultimately lowering the levelised cost of electricity (LCOE).

“At Xfloat, we aim to redefine what is possible in floating solar by combining intelligent design with environmental responsibility. Partnering with BASF has enabled us to enhance the durability of our systems with materials that meet the highest performance and safety standards – especially for sensitive applications like drinking water reservoirs,” said Avi Alcalay, Chief Technology Officer, at Xfloat.

The stabiliser meets strict drinking water standards, including the requirements of the EU Drinking Water Directive (EU) 2020/2184, Article 11(2)(b). Xfloat Ltd.’s systems are also certified under NSF-61 Section 5, making them suitable for installation in sensitive locations such as drinking water reservoirs. Xfloat’s technology is currently being deployed across the United States, the Middle East, Europe, and Southeast Asia. A recent project in Singapore reported a 28% increase in energy yield using its proprietary FPV-T platform. Supported by a growing global project pipeline, the company is scaling its operations to address rising demand for durable and high-efficiency solar energy solutions.

“Floating solar is rapidly emerging as a complementary pillar in the renewable energy landscape,” said Ricard Vandellos, Vice President, Business Management Plastic Additives EMEA and Latin America at BASF. “Our collaboration with Xfloat demonstrates how material innovation can support the long-term performance of solar infrastructure.”

This collaboration highlights how BASF’s VALERAS® portfolio supports the development of durable, safe, and sustainable solutions. By integrating Xfloat Ltd.'s intelligent floating solar design with BASF's advanced stabilisation technology, the partnership delivers a certified solution for clean energy generation on water that is suitable for deployment even in environmentally sensitive environments.
