Introduction
The Monodraught Windcatcher Sola-boost is an innovative, energy-free natural ventilation system that has been enhanced with a solar-driven internal fan. This system is designed to address global warming and rising energy costs by providing increased ventilation without energy costs.

Specifications
The Windcatcher Sola-boost system is available in various sizes (600mm to 1200mm) and can be customized in any BS or RAL color. It features a polycrystalline photovoltaic panel and a PowerTrack™ control system that optimizes solar energy use. The system includes motorized volume control dampers and a DC solar-powered boost fan.

Operation
The system operates by capturing prevailing winds and using buoyancy and stack effect to ventilate spaces naturally. On sunny days, the solar-powered fan provides additional ventilation. The PowerTrack™ system adjusts fan speed based on sunlight intensity, ensuring efficient energy use.

Control Options
The Sola-boost system offers both fully automatic and semi-automatic control options. The automatic control includes settings for full speed, half speed, and off, with manual override options. The semi-automatic control includes pre-programmed damper control based on room temperature.

Applications
The system is suitable for various building types and is particularly effective in areas with high solar gain. It ensures continuous ventilation even without wind, supporting low-energy building designs.

Technical Data
The system's ventilation rates vary by size, with additional ventilation provided by the Sola-fan. The solar panel size and typical operation time are specified for each system size.

Conclusion
The Monodraught Windcatcher Sola-boost system is a sustainable solution for natural ventilation, offering energy-free operation and enhanced performance through solar technology.
