| Summary |
This presentation and poster covers the design and installation of a 1.2 kW grid intertie with battery backup photovoltaic system at the Bilbrough/Crammer residence near the Vedauwoo exit 329 off Interstate 80. A total of 3600 W of essential loads including the refrigerator, freezer, heater fan and lighting where determined and isolated in a subpanel. A charge controller, inverter, 120V to 240 volt single phase transformer, and battery bank where sized to handle these essential loads and provide at least three days of power in the case a blackout. During normal operation the photovoltaic system will produce approximately 4.5 kW hours of electricity per day charging the batteries if necessary or feeding power back into the grid providing approximately one half of the electricity needs of the household when grid power is available. All necessary permitting and calculations were made concerning wire and conduit size, grounding, appropriate disconnecting means, and other requirements for a safe and compliant installation as directed by the National Electric Code and the electric distribution provider. The total out of pocket cost of the installation is approximately $16,000 with expected tax write-offs and grants returning about $5000 for a total installation cost of $11,000.
