SolarisKit HelioFlow™ Achieves Solar Keymark Certification

SolarisKit is proud to announce the launch of HelioFlow™, our next-generation, flat-packed solar thermal collector designed to deliver higher performance and superior reliability. Engineered for global deployment and ease of use, HelioFlow™ has successfully passed Solar Keymark certification following rigorous testing at the prestigious SPF Institute for Solar Technology in Rapperswil, Switzerland.

Certified to Perform: Solar Keymark Approval

HelioFlow™’s Solar Keymark certification marks a major milestone in SolarisKit’s mission to accelerate the global transition to clean solar heat. The Solar Keymark is Europe’s leading quality label for solar thermal products, and the certification assures customers of:

• Tested high efficiency in real-world conditions
• Durability in extreme weather environments
• Compliance with European standards for safety and performance

This certification was awarded after comprehensive evaluation by the SPF Institute, one of the world’s most respected solar testing laboratories.

What Makes HelioFlow™ Different?

Building on the innovative, award-winning design of SolarisKit’s original solar thermal collector, the new HelioFlow™ offers:

• Higher thermal performance for greater energy savings
• Optimised prismatic geometry for improved heat capture
• Compact, flat-packed design that minimizes shipping costs and emissions
• Tool-free assembly for rapid deployment in homes, businesses, and off-grid communities

HelioFlow™’s patented design ensures hot water is delivered sustainably, making it an ideal choice for markets in Africa, the Middle East, Asia, and beyond.

Proven in the Field: Real-World Success in the UAE

HelioFlow™ is already making an impact. In early 2025, the system was installed at Saqr Port, part of the RAK Ports Group in the UAE. The project involved integrating three HelioFlow collectors with a 50-litre electric water heater, reducing energy consumption and delivering over 75% of daily hot water needs through solar energy alone.
