Team Tidewater Status Update 12NOV2012

 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 $ kWh ◦ At 135 kWh it will cost us $16.15 to operate at peak performance

ProductManufacturerModel # Energy (kWh/yr) * Energy (kWh/wk) Energy (kWh/day) Max Energy (kWh/usage) Projected Max Energy usage (kWh/26 days) for competition ** Projected Max Water usage (gal/26 days) for competition ** Roomba Robot VacuumiRobot na Countertop MicrowaveKenmore Slide-In RangeGEJSP42SNSS Refrigerator/FreezerKenmore DishwasherBoschSGE63E15UC WasherBoschWAS20160UC DryerBoschWTV76100US TVSamsungUN60ES LaptopApple MD101LL/A kWh/day Notes:* Energy consumption values obtained from internet sources ** Projected max energy consumption is determined by how often the product is used during the competition

 kWh  4.79 kWh/m 2 /day  Contributing factors  10 degrees optimal panel tilt  Latitude 33.8 degrees N  Longitude degrees W  Assumptions  Minimum shading  DC to AC loss factor

 SunDrum’s thermal energy (J/day)  Allows HVAC to calculate more realistic energy loads  SunDrum’s contribution towards panels efficiency

 Efficiency of panels  Cloudy/ Moderately cloudy day

Structural calculations can be generated more accurately SunDrum placement is selected and energy loss can be calculated Design of UnIrac can be finalized
