Transcript: Wind energy We plan to use 10-50Watt solar panels with a voltage output of 12V. We plan to regulate the output using a solar charge controller. Solar Energy(what we did) Solar Charge Controller Generator Inverter Water Turbine The windmill which we had was tested by coupling with a 2.5W motor. This testing was done on terrace of Tech Park. The windmill generated effectively 0.7W of power during the testing. Solar Panel Array Thus a Savonius Turbine can be used to replace the Wells Turbine thereby reducing the plant size. The Savonius Turbine has good starting characteristics. It has good conversion rates even at low tip speed ratio. The power rating of the solar panel which is chosen is 12V/25W. In order to maximize the efficiency the panels should be made to trace the path traversed by the sun. This can be achieved by means of a solar tracking system that we have planned.

Processor We plan to couple the windmill with a 6V dynamo and test its working. Following this we plan to couple it with a 12V dynamo. We plan to connect the windmill to a similar charge controller that we have constructed for the solar panels. We plan to harness wind energy from a small scale wind turbine. The wind mill we are using is a 3 blade turbine of radius : - 42cm It can also be converted into a 6 blade short wind turbine as well. References The panel orientation is controlled by a arduino programmed servo motor. The programming should be such that the motor sweeps 25˚ every hour for a span of 12 hours thus sweeping an angle of 300˚. This is similar mechanism is used in Reflecting Telescopes. Overall Block Diagram( what it was) Binary Status Lines Tidal Energy( what we did) We are using 3 blade, 30-40cm radius wind turbine and depending on the generator it is coupled with, it can generate 2.5-20 Watts. Charge controller Controller The large scale method for harnessing tidal energy is the use of an Oscillating Water Column(OWC) employing a Wells Turbine.. The Wells Turbine can have reasonable conversion rates provided the tip speed ratio(turbine blade tip speed/inlet air velocity) is high (~10). This gives them a high Reynold’s Number and hence requires large radius for the columns. Tidal Energy Wind Turbine Generator Power Lines Coupling Solar Tracking System Green Power The sun moves from east to west in approximately 12hrs On the open coast the solar panels should be made to traverse the suns path from east to west We have planed to mount our solar panel on a 60 deg wedge such that it makes a swing of 300 degrees in 12hrs Wind energy first test results Tidal energy , we plan to harness using an oscillating water column. We plan to design this column using PVC sheets. The top of this columns will house 2 or more mini turbines connected in series that will be capable of generating 2.5-10 Watts. Charge Controller Display A.C. Load Charge Controller The solar output is harnessed using a solar charge controller which regulates and ensures constant DC Power Output. The Charge controller also has a provision for connecting a dummy load. A 555 Timer with an IC Voltage regulator can be used for implementing a solar charge controller.
