S4 innovates with its new patent
S4 BaseFlow— Ballasted PV System for Flat Roof Applications
S4 BaseFlow is a multifunction ballasted photovoltaic support system designed for flat roof applications where structural integrity, installation simplicity and operational efficiency are key requirements.
Unlike S4 Roofit, which is dedicated to pitched roof residential construction, S4 BaseFlow addresses commercial, industrial and mixed-use buildings, offering a robust and versatile solution for flat roof photovoltaic installations.
Universal photovoltaic support
S4 BaseFlow is compatible with all major photovoltaic panel formats, from standard residential modules to large industrial panels, allowing consistent system specification across a wide range of projects.
Integrated thermal air management
The system enables controlled management of hot air generated beneath the photovoltaic panels:
- hot air can be redirected into the building to support pre-heating during colder periods,
- airflow can be reversed to support natural ventilation and cooling during warmer periods.
This approach contributes to improved building energy efficiency while maintaining panel performance.
Integrated rooftop storage
A discreet integrated storage compartment beneath the panels provides secure space for tools, spare parts or technical equipment, improving site organisation and operational efficiency.
Key advantages
- Universal panel compatibility
- Optimised flat roof installation without roof penetration
- Modular, robust and easy-to-install design
- Suitable for industrial, logistics, commercial and mixed-use buildings
S4 BaseFlow complements the S4 product ecosystem by addressing flat roof applications requiring a flexible, durable and energy-conscious photovoltaic solution.
