What does a roadmap provide?

• Establish a Vision for the industry.
• Establish a strategic plan towards realizing the
  Vision.
• Instill confidence in decision makers, investors,
  and customers.
• Identify and guide opportunities for shared
  development.
• Clarify barriers and coordinate response within
  the community.

VISIONU.S. Photovoltaic Industry

• to provide the electrical energyconsumer
  competitive and environmentally friendly energy
  products and services from a thrivingUnited
  States-based solar-electricpower industry.

9
Strategies

• Maintain U.S. PV industrys worldwide
  technological leadership.
• Achieve economic competitiveness with
  conventional technologies.
• Maintain a sustained market and PV production
  growth.
• Make the PV industry profitable and attractive to
  investors.

10
Target and Goals

• Target For the U.S. photovoltaic industry to
  provide up to 15 (about 3000 MW) of new U.S.
  electricity generation capacity expected to be
  required in 2020. The U.S. cumulative PV
  shipments will be about 30 GW at this time.
• Goals
• A growth rate of 25 in PV production capacity is
  required to meet the roadmap targets for U.S. and
  international markets.
• PV system costs to the end user of 3.00/Wac and
  1.50/Wac by 2010 and 2020, respectively. Total
  manufacturing costs will be about 60 of the
  system cost.

Market Barriers and Solutions

• Value Full value of solar electricity as
  distributed, clean, renewable energy must be
  described and captured for policy makers,
  investment and financial communities, and
  consumers.
• Products Products must be easier to use.
• Not a techie project more like a household
  appliance
• Reliability comparable to (or much better than!)
  other electricity options
• Standards and codes
• Policies Public policies must reflect value and
  importance of solar electricity
• National interconnection standards
• National net metering legislation
• Electricity restructuring should promote
  renewable energy introduction
• Financial incentives to stimulate market
  expansion in early stage

17
Technical Barriers and Solutions

• Infrastructure Greater cooperation between
  material and equipment vendors, PV module
  manufacturers, and system component
  manufacturers.
• Technical
• Higher performance
• Higher throughput
• Module materials

18
Conclusion

• Solar-Electric Power has very attractive features
  that make it a natural component of a sustainable
  energy future for the U.S. and the world.
• The U.S. PV Industry is completing development of
  a roadmap that will delineate a path towards
  achieving a prominent role in energy generation.
  Anticipated completion of the roadmap is early
  2001.
