3 * 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.

4 * Three Vertical Axis Savonius style Wind Turbines. * Cut-in wind speed 2.5 m/s & Cut-out wind speed 18 m/s. * Scalable to meet user defined KW need interconnection cables provided. * Integrated Maximum Power Point Tracking with smart bus logic control technology 48vDC. * Temperature sensing electronics for thermal protection. * Able to withstand temperature ranges from -30 C to 50 C. * International Protection Rating (electronics enclosure)- IP65

8 Turbines * At the core of each product is the Vertical Axis Wind Turbines (VAWT) that have been selected for use by the WindStream engineers. In developing the product, WindStream conducted extensive research regarding the design and construction of Savonius type turbines. * Our models involve light, efficient turbines that have enough transient response to fully take advantage of the energy creation opportunity that bursts of wind provide. The turbines want to be optimized for the wind speeds that are typical in the urban landscapes and capable of collecting wind energy when others have not yet started, which our Savonius design has made possible. WindStream currently maintains a proprietary stamping process (pilotless progressive die with differential pre-stretch) for the turbine

9 Generators * WindStream has designed, tested and manufacturers its own generators to uniquely suit the conditions in which the SolarMill products will be placed. The topology we ve chosen is a coreless axial-flux permanent magnet (AFPM) machine. Typical generators are high-speed, low-torque devices. In those cases a gearbox is used to increase the rotational speed of the rotors inside the generator. Gearboxes add additional friction, negatively affecting performance and efficiency, and require periodic maintenance. Gearboxes are the single most common point of failure in any wind turbine. * We utilize a direct drive permanent magnet solution which is free from the maintenance issues that commonly plague gear driven generators. AFPM machines can offer greater torque capability operating at lower speeds. The generator was custom-designed specifically matched to the torque of the turbine thus optimizing the rotational and torque characteristics of the turbine to the generator.

10 Mechanical Braking System * The unit is equipped with a failsafe centrifugal braking system designed to protect the turbines and generators at high wind speeds. The braking system is self-resetting and will automatically disengage when the wind dies down. The brake provides no friction prior to engaging. Easy Assembly * SolarMills are mass-produced utilizing manufacturing processes commonly found in the automotive and aerospace industries and a patented (pending) process to produce our steel turbines. These products produce energy from winds coming from any direction, pose no threat to the environment or to wildlife, are silent and free from hazards and other mechanical deficiencies often found in horizontal axis devices, and do not require complicated masts, guy wires or foundations for installation.

11 Corrosion Resistant & Steel Construction * All steel parts are pre-galvanized and also coated with PPG Spectracron 360 2K, which provides another level of corrosion resistance. Aluminum, or Stainless components are used where appropriate. The main structure is made of heavy gauge steel for enduring strength. All fasteners are zinc coated and the plastics are stabilized against UV so they won t break down in the sunlight. Mounting Options * There are several options for mounting the SolarMill, which can be configured to multiple heights and can accept panels as necessary. SolarMills can accommodate practically any roof type. In some instances it is unnecessary to penetrate the roof and you may use a ballasted structure instead. Inverter Options * WindStream has identified two low-cost inverter options that allow for off grid or on grid installations. Circuit Protection * The electronics provide circuit protection for over-voltage and over-current by monitoring the current and voltage in each system.

12 Wind and Solar Electronics * WindStream has designed and built its own MPPT electronics circuitry which controls all aspects of the power generation of both the wind and solar sections of the products. This smart controller handles the onboard electronics that properly load the generators and output the energy that is then used by the customer. The WindStream controller dynamically adjusts each of the generators in the system based on wind speed and direction of the wind in order to maximize the power that can be extracted from the available wind energy. This processor controlled unit then rectifies the AC power to DC and passes it along to the adjacent SolarMill to be summed and either stored to a battery and then passed along to an inverter and used by the customer. On and Off Grid Installation * SolarMills are distributed energy systems designed for either grid connected, or off-grid applications. The product utilizes a built in charge controller to regulate a 48VDC lead acid battery system. When grid connected, the electrical energy created is directly fed into the electrical service panel offsetting the overall draw. In off-grid applications, it is output via a DC/AC or DC/DC converter according to the type of loads that need to be served.

18 *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.

19 *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.
