The SolarMill®

The SolarMill Generates:

• Daytime energy from the sun and wind

• Day & Night energy from the wind

• Energy even on cloudy days

• More energy on hot sunny days due tocooling effect on solar panels by wind

An Efficient Way of

Combining the Power of Wind and Solar!

• Standing about 1 meter tall, SolarMills meet most permitting buildingcode requirements.

• SolarMills harvest energy from the sun and wind simultaneously and alsoindependently.

Why SolarMill?

• The SolarMill technology smooth’s out the highs and lows of energy

generation periods due to seasonality as solar irradiation and wind speeds

change throughout the course of the year.

• The hybrid solution will compensate for seasonal losses of power generation

while depending on any one type of renewable energy system.

Product overview-SolarMill

• SolarMill is a Hybrid energy system which deals with both Solar and wind energy.

• Hybrid system is based on a modular, scalable, distributed renewable energy system

designed and optimized for both on and off grid installations.

• Wind energy device, utilizing three low-profile vertical axis wind turbines (VAWT)

mounted on a single base.

• Incorporates P.V. technology, creating the greatest energy generation.

Superior Performance

• Early energy production

• Better daytime peaks

• Late evening & night-time

energy generation

The Technology:

• WindStream’s Maximum Power Point Tracking (MPPT)is applied to each turbine independently.

• Current production technology and configuring for this unique application,the turbines, generators, and electronics will allow for the addition of windgenerating power with a minimal amount of added weight.

• Onboard “Smart” electronics designed to control 3turbines connectedin series running the length of the tower, outputting power to the equipment locker.

• Savonius Turbines accept wind from any direction and accommodate changes in wind direction.

• SM1 is capable of producing 576 kWh/ Year(@ 6kWh/m2/day and 5m/sec average yearly wind speed)

Construction

SolarMill Assembly:

• 3 Vertical Axis Turbines mounted on a single base

• Turbines (Savonius) produce energy by accepting winds coming from any direction

• Cut-in wind speed – 2 m/s & Cut-out wind speed – 18 m/s

• Silent operation• Designed for both On-

Grid and Off-Grid applications

Construction contd..

Reliable

• Corrosion Resistant Material: all steel parts are pre-galvanized.

Aluminum or stainless components are used where appropriate.

• Circuit Protection: Electronics provide protection for over-voltage and over-

current by monitoring the current and voltage in each system.

• Mechanical Braking: The unit is equipped with a failsafe centrifugal

• braking system designed to protect the turbines and generators

• at high wind speeds (beyond 18.5 m/s).

• Able to withstand temperature ranges from -30°C to 50°C.

Advantages of SolarMill

• Easy to mount on any rooftop; no complicated masts, guy wires, or towers.

• Simple ballasted installation that avoids roof

penetration.

• Environment-friendly, silent operation.

• Higher power density per square foot.

• Scalable power generation.

• Mechanical braking at high-speed winds beyond 18 m/s.

• Increases the battery life & minimizes the battery

storage capacity.
