The SolarMill is a unique, hybrid energy solution that allows customers access to an uninterrupted supply of clean, renewable energy. The SolarMill is a modular, renewable energy system designed and optimized for both on-grid and off-grid applications.

1. 1. Product Overview – The SolarMill
The SolarMill is a unique, hybrid energy solution that allows customers access to an uninterrupted supply of clean,
renewable energy. The SolarMill is a modular, renewable energy system designed and optimized for both on-grid and
off-grid applications. It utilizes 3 small vertical-axis wind turbines mounted on a single base, which can be
interconnected to maximize wind energy production in low and turbulent wind environments, commonly found in urban
settings. This scalable system integrates photovoltaic panels into the structure, using the same mounting structure,
electronics and inverters to capture the complementary solar and wind resources.

2. 3. Advantages of SolarMIll vs. Only Solar:
SolarMill Only Solar
Production
• 24-hour power production capability • Daytime production only
• Mitigates daily and seasonal fluctuations of
• Lower production in shorter days and bad weather
renewable resources.
• On-board MPPT maximizes efficiency and
• System failure based on single component failure
eliminates series failure
Design
• Systems designed to plug-n-play and scales easily • Non-standardized packaging prevents scalability
• System allows for custom configurations • Little to no customization and inefficient inverter
maximizing inverter efficiency deployment
• Site specific flexibility and customization • Limited to factory customization
• On grid and off grid capability by design
• For off grid, requires significant additional
hardware
• Built-in monitoring and reporting capability on
• No inherent intelligence
each unit
• Customizable colours and visually engaging • No aesthetic value
Energy Density & Life Expectancy
• Higher power density per square foot versus solar • Requires more square footage for equal
(30 Watts/ sq. foot) generation (13 Watts/ sq. foot)
• Unit life expectancy 25 years on all components, • Questionable maintenance and life expectancy on
including Tier 1 panels Tier 2 and Tier 3 panels
• Environmental friendly & silent operation
Battery Life
• Extends battery life • Reduced battery life due to deep cycling
• Hence, Battery replacement costs reduced • Hence, Battery replacement costs increased
* During winter air is heavier compared to summer yielding more power from turbines.

3. 4. Additional Benefits of SolarMill
®
Over Only Solar / Only Wind:
• Hybrid Renewable System – Combining wind and solar energy resources in a fully integrated platform.
• High Energy Density – Wind and Solar energy generation within a compact footprint, creates the greatest
energy density (Energy/sq. meter) of any product on the market.
• Occupies Less Space – The SolarMill occupies less space (around 30% for 1 kW) than only solar or only wind of
the same capacity.
• Scalable - The units can be interconnected to increase a user’s energy production capability.
• Unique - The hybrid concept of the SolarMill® seamlessly integrates wind and solar energy generation in a single
unit. This allows the product to be an effective solution in markets where the natural resources available for
only wind or only solar energy generation do not justify investment.
• Increases Battery Life – Unlike Solar which is capable of charging the battery only during available sun hour, the
SolarMill is capable of charging a battery 24 hours a day, limiting the “depth” of discharge of the battery &
thereby increasing battery life & state of charge.
With installations in the cold of Scandinavia, or in the sunny and salty Caribbean Islands, or subject to the sandy desert
heat in the Middle East, SolarMills have performed as expected, providing energy to our customers worldwide.
SolarMill vs. Only Solar: Impact on Battery
• SolarMill charges 24 hours a day, limiting the • Solar charges only during daylight hours
“depth” of discharge of the battery.
*Note: numbers are shown for easy understanding & do not represent real values.
• Battery life is dependent on the number of charge cycles and the depth of discharge.
• Batteries may last up to 20%-30% longer in a SolarMill installation, reducing the LCOE and the ROI over time.
