Modular Rooftop Wind Turbine Design

I’m developing a compact wind-turbine system for residential rooftops that mirrors the Ridgeblade concept in layout yet strips the design down for easier manufacturing and lower cost. Each module must deliver roughly 1-2 kW and lock together so homeowners can scale output simply by adding more units.

The turbine will be built entirely from aluminium or stainless steel, paired with an integrated permanent-magnet generator, and mounted on an adjustable base that can match a range of roof pitches without special carpentry. My key goals are quiet operation, high efficiency at low wind speeds, and a bill of materials that stays friendly for small-batch production. Solid modelling and CFD/FEA validation in packages such as SolidWorks, Fusion 360, ANSYS or similar should guide the final geometry, while manufacturability remains front-of-mind.

Deliverables
• Detailed 3-D CAD files for all components, including modular interlock features and adjustable base
• Engineering drawings with tolerances, fasteners, and material call-outs for aluminium and stainless versions
• Generator–rotor coupling design and performance curve estimate for the 1-5 kW range
• Assembly guide and exploded views suitable for a local fabricator
• Brief costed bill of materials and notes on any off-the-shelf parts

Acceptance criteria: structural safety factor ≥2 under 40 m/s gusts, tip speed noise below 55 dB at 10 m/s, and modular alignment within ±1 mm when three units are joined.

If you can translate aerodynamic insight into a manufacturable, roof-ready product that meets these targets, I’m ready to move quickly.
