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 highefficiency crystalline solar cells.

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.

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.

Conclusions.
1. Our SA, which have maximum of hard submodule nambers,
have maximum value of power per unity of weight and minimum
cost per unity of power.
2. It means that our SA are most effective, most light and most
low cost in comparison with their analogues and competitors.

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.
