1. Making Rooftop Wind Energy Viable
Introduction and One Sentence Product Description
Making Rooftop Wind Energy Viable
Erika Boeing

2. The Renewables Industry is Thriving! ….. but not rooftop wind…..
9.6 GW Installed in US in 2018
5 GW installed in US in 2018
Small Wind?
8 GW Installed in US in 2018
4.3 MW Installed in US

3. Small Scale Wind Is Prohibitively Expensive
Cost Today: $5.48/Watt – payback is often longer than lifetime
Soft Costs: Reduced through Market Innovations
Hardware Costs: Reduced through Technical Innovations

4. Reduce Soft Costs through Sale to Solar Installers
Sell to Solar Installers
Installers are desperate for ways to diversify
Use their costs for customer acquisition, permitting, and installation
Edge of the roof perfect for wind, unused for solar
Target Commercial and Industrial Roofs
70% cannot produce energy with solar alone
High peak demand charges
Empty space available on rooftop edge
Ideal wind flow conditions

5. Wind Speed Increase at the Edge of a Roof
CFD Model of Wind Flow
Validated with:
In-depth sensor study at Argonne National Lab
Computational Fluid Dynamics Modeling
Work with existing edge of roof technology
Up to 3x power increase at edge of roof

6. How we Capture Faster Speed Wind
*Conceptual design – subject to change with CFD Modeling and Architectural Work
Additional Cost-Saving Benefits:
Mounting with standard solar racking by solar installers
Ability to add solar on top of channel and produce both wind and solar

7. Power Electronics Solution – Intermediate Energy Storage
Our Patent-Pending Invention:
Typical:
Power Electronics are often as much as 50% of total wind turbine costs
Using the edge of the roof does nothing to reduce this cost!
We need another invention
Generator
Flywheel Energy Storage
Generator
Inverter
Inverter
We temporarily store the wind turbine energy in a low cost flywheel, smoothing out peaks and valleys of generation, and reducing the size and cost of the generator and inverter

8. Validated Powertrain Solution

Photo Credit: Argonne National Laboratory
System feeds in wind speeds from edge of roof
Powertrain Solution (our key differentiator) validated through prototype built at Argonne National Lab

9. We Make Wind Energy Economically Viable
Edge of Roof Performance Advantages
Solar-like Infrastructure Costs

10. Serviceable Addressable Market
We offer the opportunity to add an average of 30% additional energy to an average building rooftop
In the US Market this is an opportunity of:
901 Million in 2018
1.51 Billion in 2023
We add onto a market with a 18% CAGR today
Focus on New Solar Installs rather than retrofits or new wind buildings
*Taken from Solar Energy Industry Association Predictions

11. Current Progress
Technical and Market Validation
