Solar Power Photovoltaic Modules Outputs energy as DC electricity DC is converted to AC using an inverter Conversion losses can be as high as 10% Fig. 1 http://energytechstocks.com
Mitsubishi Electric Photovoltaic Modules We recommend the Mitsubishi Electric TD175MF5 Not actually part of the technical core Necessary to power it and the home 175 Watt panels Output approximately 1.17 kWh per day 28 panels recommended for our prototype Fig. 2 http://www.wholesalesolar.com

Unimplemented Concepts Fig. 3 http://www.ia.nrcs.usda.gov Green Roof Too unsightly and potentially high maintenance Too farfetched for a marketable home • Consolidate all high energy using appliances to reduce transmission losses • Electrical losses too insignificant to warrant the inconvenience Fig. 4 http://www.kingskitchens.com
Cost Initial cost estimate of materials (not including manufacturing or labor costs): Approximately $51,000 Including cost of solar panels: Approximately $73,000 Fig. 5 http://www.pensionriskmatters.com
Heat Pump Goodman Self-contained Heat Pump Acts as an AC unit in the summer Reverses and acts as a heater in the winter Electric back-up heater Fig. 6 http://www.alpinehomeair.com
Solar Hot Water Heater Fig. 7 http://www.htproducts.com/superstorsolar.html Superstor Solar SE Series Solar Water Heater Powered directly by designated solar panels Direct power from solar panels saves energy over AC conversion
