  1. Solar Decathlon Team Tidewater Status Update 12NOV2012

  2. Gaming • Appliance Analysis • Got the average yearly usage from internet sources • Broke it down to kWh/day and /usage • Determine the Max Energy Consumption for Competition • Measured Test • Different testing procedures per appliance • Water and electrical consumption • Dinner Party • How many people eating • How often each appliance is used • US average residential rate $0.1151 kWh • At 135 kWh it will cost us $16.15 to operate at peak performance

  3. Energy Analysis of Appliances

  4. Bosch Solar Module 255 Wp/ M-215 Micro Inverter Performance

  5. Performance of 40 panels in Irvine, California during October • 37.2903 kWh • 4.79 kWh/m2/day • Contributing factors • 10 degrees optimal panel tilt • Latitude 33.8 degrees N • Longitude 117.7 degrees W • Assumptions • Minimum shading • 0.843 DC to AC loss factor

  6. Calculations in Progress • SunDrum’s thermal energy (J/day) • Allows HVAC to calculate more realistic energy loads • SunDrum’s contribution towards panels efficiency

  7. Calculations in Progress • Efficiency of panels • Cloudy/ Moderately cloudy day

  8. Structural calculations can be generated more accurately • SunDrum placement is selected and energy loss can be calculated • Design of UnIrac can be finalized Layout of Panels

  9. HVAC-Sun Drum Sun Drum Heat Gain Calculations

  10. HVAC-Vitocell Recovery Rate Calculations

  11. Structural Update • Framing ceiling • Insulation • SIPs? • Space Frame Calculations

  12. Conclusion and Questions
