Proprietary information statement

• The technology material presented in this talk is
  available for licensing or joint product
  development.
• None of the slides contain any confidential or
  proprietary information which would prevent
  patenting the technology.

Problem Description Market Need

• In last 5-10 years we are the witnesses and
  participants of revolution in the fields of
  information systems, digital electronics,
  communication and power engineering.
• As a result of it is appearance of hundreds of
  millions independent portable (pocket) electronic
  equipment in mass usage of the ordinary people.
• Such equipment are
• portable computers, audio - players, radio,
• photo- and video- cameras,
• satellite navigators and telephones,
• multifunctional cellular (mobile) telephones,
• medical equipment and others.

Problem Description Market Need

• Independent power supply of this equipment in
  most cases is provided by portable batteries,
  which require periodic recharging.
• Batteries can be charged by traditional charger
  which use centralized electric power greed or car
  electric power system.
• Very often millions people (in business trip,
  vacation travel, military action) have need in
  charging battery of cellular or satellite
  telephone or computer, in situation when there
  are no traditional charger.
• In this case it is necessary have another,
  alternative electric power supply. Such source of
  electricity can be solar array (SA).
• Using of ordinary SA with large sizes for
  charging batteries of pocket electronic equipment
  are not comfortable.

We propose

• New design and
• technology of
• folding
• solar array
• for portable
• electronic equipment

Brief technology description

• The principle of generation of electrical energy
  by solar arrays is based on photovoltaic effect
  in semiconductor structures with p-n- junction.
• The monocrystalline silicon as material for solar
  cells is used. It allows have high efficiency of
  photoconversion and the large service life.
• The hermetic sealing is carried out with use of
  technology of hot lamination in vacuum.
• In a Fig. 1 the photo of vacuum laminator
  VL540/290 which was developed and made in our
  company was used for manufacturing experimental
  samples of solar arrays is represented.

Advantages

• Folding construction large sizes in operation
  position and small sizes in a transport position.
• High reliability high resistance to negative
  climatic and transport factors, large operate
  resource.
• High-efficiency possibility to use
  high-efficiency crystalline solar cells.

Stage of development

• Experimental samples are made.
• Laboratory test ar? carried out.
• Laboratory technology are create (on the
  base of developed and made in our company
  technological equipment ).
• In a Fig. 2 the photo of experimental sample of
  solar array for mobile phones SBMT-S-8.0-0.23,
  which can be used and for other portable
  equipment is represented.

Targeted Market Segment

• Portable solar arrays can be used in such areas
  of application
• Communication.
• Computer equipment.
• Military equipment.
• Photo-, video- audio- equipment.
• Tourism and everyday life.
• In one word anywhere where it is necessary to
  have electric energy but stationary electrical
  grid is absent.

The potential buyers our SA can be part of the
users of any portable equipment, which sometimes
get in a situation when there is no an available
usual source electricity for charging battery of
their portable (pocket) electronic equipment.
As number of portable equipment owners is very
great (hundreds of millions), the market of our
SA is very great too (tens of millions). Well
known problems of ecological and raw crises give
the basis to consider, that the market our
special SA for the portable electronic equipment
will be constant extend.
13
Competition

• So.co solar charger mobile computing company.
• Solar Energy Allians.
• Other companys producer solar arrays for
  portable electronic equipment.
• We will beat our competition by more high
  resistance our SA to negative climatic and
  transport factors, high reliability and large
  operate resource.

Competitive Matrix
15
Opportunities

• We am seeking potential partners and licensees
  for further research and developmentin the field
  of solar power engineering.
• In our estimation cost of project for development
  of new tipe of solar arreys or solar micro-power
  plant for modern portable (pocket) electronic
  equipment is 70-90 thousands american dollars.
• Necessary time for project execution is 1-2
  years.
