Boosting solar resilience through Xfloat and BASF collaboration

• Decades of durability for floating solar systems
• Advanced BASF stabilizers meet Xfloat innovation
• Certified solutions for strengthening water resilience

Xfloat Ltd., a pioneer in floating solar technology, has partnered with BASF to improve the longevity and sustainability of floating photovoltaic (FPV) systems. This collaboration brings together Xfloat’s innovative sun-tracking platforms (FPV-T) and an advanced light stabilizer solution from BASF to deliver durable, high-performance solar solutions for global deployment.

Together, Xfloat and BASF have integrated Tinuvin^® 2730 ED, a proprietary light stabilization solution from BASF that protects High Density Polyethylen (HDPE) from degradation, into the float design to ensure long-term durability in demanding environments. By incorporating the additive solution into its HDPE float design, Xfloat enables the floats to withstand harsh environmental conditions for over 30 years, aligning with the lifespan of solar modules. This durability reduces maintenance and replacement costs, contributing to a lower levelized 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 stabilizer complies with stringent drinking water regulations, including the EU Drinking Water Directive (EU) 2020/2184, Article 11(2)(b). The Xfloat systems are certified under NSF-61 section 5 and suitable for deployment in sensitive environments such as drinking water reservoirs.

Xfloat’s technology is already being deployed in the United States, the Middle East, Europe, and Southeast Asia. A recent project in Singapore demonstrated a 28 percent yield improvement using their proprietary FPV-T. With a growing global pipeline, Xfloat is scaling its operations to meet increasing demand for resilient and efficient 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 partnership underscores how BASF’s VALERAS^® portfolio contributes to durable, safe, and sustainable solutions. By combining Xfloat’s intelligent floating solar design with BASF’s advanced stabilization technology, the collaboration delivers a certified solution for clean energy generation on water – ready for deployment even in environmentally sensitive locations.
