•As a result of this senior design project, we have designed an off-the-grid lighting solution that will be powered by a vertical axis wind turbine and a solar PV panel, to power a LED streetlight. •A 15° angle for the converging section is an ideal angle to amplify the wind without causing separation •The rated power output for our wind turbine and solar panel prototype is 480 Wh for a windswept area of 0.545m2 in the Syracuse area •Our working prototype is ready for further performance testing
Compressive stress due to Weight: 59 KPa, (max – 152 MPa) Strain due to Compression: 2.2 mm At wind speed of 60 m/s (134 mph), Max Shear Stress: 1.65 MPa Yield points - Steel Pole (145 MPa), and Aluminum Pole (96 MPa) Recommended to use additional precautions in testing of prototype: -anchor lines -safety net around housing In production, adapt free-rotating mechanism for safety.
