InsulationVacuum-insulated panels and double-walled storage tank20% faster heat retention than traditional models, reducing standby losses.
InstallationFreestanding, adjustable tilt mechanismEasy setup and optimized sun exposure for maximum solar absorption.

Customization guide

Adjustable tilt angles (0°–90°) allow customization for geographic latitude and seasonal sun angles. Choose between pressurized (for high-demand systems) or unpressurized modes based on plumbing infrastructure. The open-loop design supports integration with backup heaters (e.g., electric/gas) for hybrid systems.

Get inspired

With the adjustable tilt mechanism, you can optimize solar absorption by aligning panels with the sun’s angle. The pressurized mode ensures hot water delivery to upper-floor fixtures, while the unpressurized system reduces installation complexity for small-scale use.

Supplier's note

  1. Three Technical Breakthroughs:

    • SUS316L Material: The Pro model’s full-body stainless steel construction triples corrosion resistance compared to industry standards, enabling use in coastal or industrial environments.
    • ICS Design: The integral collector storage eliminates standby heat loss, boosting efficiency by 20% over traditional flat-panel systems.
    • Adjustable Tilt: A patented tilt mechanism allows real-time sun tracking, increasing daily solar gain by 15% in variable climates.

  2. Optimal Version Selection:

    • Base Model: Ideal for households with moderate hot water needs (≤3 bathrooms). Its 3 bar pressure suits standard plumbing systems.
    • Advanced Model: Best for commercial kitchens or hotels requiring 5 bar pressure and 300L storage. The SUS304 coating balances cost and durability.
    • Pro Model: Designed for industrial facilities or high-altitude regions. With 8 bar pressure and SUS316L corrosion resistance, it handles extreme conditions while maintaining 85% thermal efficiency.

*Pro Model’s 8 bar rating exceeds industry benchmarks by 33%, supporting high-pressure commercial systems.
