2. Mission Statement Create an efficient and comfortable operated by solar power Primary Market: Energy-conscious consumers in the market for a new home Secondary Market: Any consumer in the market for a new home Assumptions: Sufficient energy produced to support common household appliances, Means of energy production are not obtrusive to home design, efficient energy production Stakeholders: Home buyers, real estate agent, designers, contractors, construction crew and investors
3. Customer Needs The home must generate enough power to maintain temperature at 72 degrees Fahrenheit Generate enough power to maintain a hot water temperate at 130 degrees Fahrenheit Generate enough power to maintain one television for 10 hours Generate enough power to run two computers Generate enough power to run the stove and oven for 1 hour Generate enough power to run one washer and drier cycle 4 times a week Generate enough power to run all the lights in an average household
4. Hierarchial List The home must generate enough power to heat or cool the home to 72 degrees. ***Energy efficient air conditioner. ***Energy efficient heater. The water heater must generate enough heat to maintain a temperature of 130 degrees. ***Energy efficient water heater . The home must be able to heat enough water to sustain three fifteen-minute showers a day. **Water heat must maintain a high volume of water. The home must have enough power to run at least one television for ten hours. **High capacity battery to maintain enough electrical energy to power the television. The home must have enough power to run at least two computers. **High capacity battery to maintain enough energy for daily computer usage. *Clean energy electrical outlets for computer usage. The home must have enough power to run the stove and oven for about an hour. ***High capacity battery to maintain heat for stove or oven for an extended period of time. The home must be able to power the washer and dryer for the duration of the cycle four times a week. **High capacity battery to maintain sufficient power to run the cycles at their highest energy needs. The home needs enough power to run all the lights necessary in the average sized home. ***High capacity battery allows constant power to keep all the lights in the home running. **Enough power is generated to allow all the lights to be turned on at once if desired. The light fixtures should all be compatible with fluorescent light bulbs. *The fixture can adapt to the power needs of any light bulb used.

9. Concept Generation Concept A Utilizes seven solar panels Provides sufficient power needs Consumer makes no profit from Power Company Cost is minimal - $3715 total (includes panels and 24V DC inverter) Concept B Utilizes one-hundred and forty-two panels, covers entire roof Provides much more than power required by the home After ten years, consumer can make around $17,000 in profit from power buy-back (assuming the Power Company would pay $.08 per kW/hour, 12 hours a day) Concept C Utilizes one-hundred and twenty-five panels Consumer will “break even” after ten years, as buy-back from the Power Company will eventually equal initial cost (approximately $62500)(assuming $.08 per kW/hour) All numbers utilize SHARP 24v 208W Solar Panels, priced at $949 for a set of two. Also included is an XP125 24V DC inverter, priced at $215. Estimated price does not account for any installation or other services.
