Xfloat/BASF collaborate on solar resilience for FPV systems

Xfloat Ltd., a pioneer in floating solar technology, has partnered with German materials firm BASF to improve the longevity and sustainability of floating photovoltaic (FPV) systems. This collaboration brings together Xfloat’s sun-tracking platforms (FPV-T) and an advanced light stabiliser 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 stabilisation solution from BASF that protects 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 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 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 US, the Middle East, Europe, and Southeast Asia. A recent project in Singapore demonstrated a 28% 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.
