Title: Cal Poly SuPER Project: Progress Report and Plans


1
Cal Poly SuPER Project Progress Report and
Plans
  • EE 563 Graduate Seminar
  • October 6, 2006
  • James G. Harris, Professor
  • EE Department and CPE Program

2
Cal Poly SuPER Project Outline
  • Background rationale for project
  • Progress Report for Last Year AY 05-06
  • Plans for This Year AY 06-07
  • Conclusion and Invitation to Join Project

3
Background - Electrification
  • Electrification National Academy of
    Engineerings top engineering achievement for the
    20th Century
  • Estimated 1/3 of population (now, 6B) do not have
    access
  • Significant proportion of remainder does not have
    reliable access to battery or grid
  • 18,000 occupied structures on Navajo Nation lack
    electrical power (2001 legislation)

4
Background - Significance
  • Impact of electrification significant
  • Transformation of Western world
  • Thomas Hughes Networks of Power
  • People who caused change
  • Social Impact standard of living
  • Recognized by National Renewable Energy
    Laboratory in late 1990s
  • Village Power Program
  • Development of microfinancing

5
Background Solar Insolation
  • Goal to provide electrical resources to people in
    underdeveloped countries
  • Leapfrog technology no need for 100 years of
    development
  • Example of cell phone in Asia
  • Review of global insolation map
  • Poorest people (1-2 a day income)
  • Within plus or minus 30 degree of latitude
  • Highest values of solar insolation (minimum W
    hr/sq m/day)

Background DC Power
  • Solar photovoltaic systems inherently DC
  • History of DC (Edison) versus AC (Westinghouse
    and Tesla) at end of 19th century
  • DC versus AC for generation, distribution, and
    utilization
  • Initially, applied to lighting
  • Lighting today
  • 60W incandescent bulb and 20W compact fluorescent
    bulb lumens
  • Equivalent to 3W LED technology, and improving

8
Background DC power loads
  • Efficiency of electrical motors few horsepower
  • Permanent magnet DC motors
  • Electrical appliances
  • Computer 50W laptop (DC)
  • TVs, radios use DC power
  • RV 12V DC market kitchen appliances
  • Portable power tools battery powered (DC)
  • Computers wireless connection
  • Internet, phone (voice over IP), TV, radio,
  • Education MIT Media Lab 100 laptop project

9
Background Moores Law
  • Stand-alone solar photovoltaic system technology
    is mature, e.g., Sandia Handbook
  • Application of Moores Law to development of
    SuPER system
  • Solar cell development commercial and research
    lab
  • Estimate 5 per decade with base of 16 in 2005
  • Implies 25 efficiency in 2025
  • DARPA RFP 1000 units of 50 efficiency

14
Background Solar and DC Power
  • Conclusion
  • Solar photovoltaic is poised for leapfrog
    technology
  • Many development tools available
  • Expectation of future efficiencies
  • Sustainable power source
  • Digital control of standalone system
  • DC is power of future
  • Decentralized
  • Matched to source and loads

15
Background Overall Cal Poly SuPER System Goals
  • Design lifecycle of 20 years
  • Total Cost less than 500 for 1 sq m PV module
    including battery replacements
  • Mean time between failures (MTBF) 25 years
  • Mean time to repair (MTTR) 1 hour
  • Power depends on PV efficiency and battery
    storage capacity

16
Why? Broader Impact of SuPER Project
  • Provides family owned electrical power source
  • Only electrical power source for family
  • Increasing power resource with time
  • With financial business plan 2-3 per month for
    all electrical power needs
  • Decentralized, sustainable development of
    electrical power in poorest countries
  • SuPER system potential resource for raising
    standard of living of poorest to par with rest of
    world

17
Background Five Year Plan for Development
  • Five years for completed design, development, and
    field testing
  • Includes business plan, documentation and
    dissemination
  • First three years for prototype development
  • Three generations at one year for each
  • Last two years for field testing
  • Establishing contacts overseas now

18
Progress Report Technical Description of SuPER
System
19
Prototype Development Phases
