Solar Panels Efficiency – Range,Technology Dependence,Companies with Highest Efficient Solar Modules

April 2, 2011Solar Panels are now available from hundreds of different manufacturers using different technologies like crystalline Silicion, CIGs and Cd-Te. The Solar Panels Efficiency also varies a lot, depending on the solar panel manufacturer and the technology used. The cost of the solar panel can also vary a lot depending on the retailer, size of the solar panel, technology and the brand. This makes buying solar panels a confusing problem though most residential and commercial buyers are not involved leaving the decision to the solar installer/EPC company. Solar Panel Efficiency can also vary in the same brand, as a company produces various solar panels aiming at different segments of the market as well as different customer needs.
What are the Different Types of Solar Panels
Size
Solar Panels come in all sorts of sizes, colours and power. Solar Panels of 20-40 Watts are typically used for applications like a Solar Lamp, Lantern and products using small amounts of power. For Putting Solar Panels on the Roof for Generation of Electricity, sizes vary from 150 Watts to 300 Watts.
Type and Color
There are also 2 different types of Crystalline Silicon Panels – a) Monocrystalline b) Multicrystalline Panels. In general Monocrystalline Panels give higher amounts of power and cost more. Solar Panels generally come in blue color though black color can also be found.
Thin Film Panels
Thin Film Panels are generally used for Building Integrated Photovoltaic (BIPV) applications where the Panels are integrated as a part of the Building Structure. This is in not prevalent in India as of now but will become quite pervasive in the future.
Solar Panel Efficiency Technology and Range
Solar Panel Efficiency can be as low as 7% for amorphous silicon technology to as high as 18% for mono-crystalline silicon technology. Note some of the solar panels used in spacecraft have cells which have conversion factors ranging as high as 40%, but those are niche applications. Solar Panels made by First Solar using the Cadmium Tellurium Technology are in the range of 11-12%, while the CIGs technology which is being used to make solar panels by a number of companies like Miasole, Solyndra, TSMC and other have the range between 10-13% currently. Note Solar Panel efficiency is constantly increasing for all technologies each year.
Companies with Highest Efficiency Solar Panels
The Companies that make the Solar Panels with the highest efficiencies are Sunpower and Panasonic/Sanyo. Sunpower has the highest efficient solar modules in the market using a proprietary process and has solar cells with efficiency reaching a top limit of 24%. Sanyo also has very efficient solar panels under the HIT brand name. These solar panels also approach the 18% range (solar modules not cells). Normal crystalline plain vanilla solar panels come in the range of 13-14%. Note solar modules have lower efficiency than solar cells as some area is left for the frame etc. There are other companies that are fast catching up to Sunpower and Sanyo in the high efficiency solar panels as well. Note higher efficiency solar panels sell at higher prices per watt as the require lesser area. AUO which has a JV with Sunpower has recently claimed to have produced the higher efficiency solar panel.

Dear Sirs\ Mis, our company is interested in quickly attracting venture
funding to finish work on the technology of production of
solar modules with high efficiency. Nizhi request for funding and in the
annex to the letter the results of our work in the form of a report
We offer more detailed information on our company and demand for grant
capital funding in the amount of – $ 3000 000.
Inventor of.
Company- SOLARUS ENERGY Ltd
Address – 454080 RUSSIA, 52 \ 74 St. VOLODARSKOGO, CYTY CHELYABINSK
CONSTRUCTION TECHNOLOGY – technology perfected laboratory,
to manufacture industrial design and conduct an independent test.
REQUIRED AMOUNT OF VENTURE FINANCING – $ 3000 000.
The additional informationFinancing term – 18 months. Return of the
investor – in the course
10 days after the expiration of funding.
PROPOSAL FOR COOPERATION for venture investors
After production of the industrial design and an independent test, we
propose % Of revenue from the sale of technology.
COMMERCIALIZATION developed technology.
Our technology has a wide range of potential buyers.
This technology allows all companies to manufacturers of solar modules
very easy to integrate our technology into an existing, technological
complex. It is planned to implement the technology on a territorial basis —
right to the technology will be limited to use by the buyer on the
Territories
and obemu release.
INFORMATION TECHNOLOGY
At present the main trends in development by improving the efficiency of
photo electric plates in the application of new non-silicon materials.
So a few days ago, the Japanese company Sharp after 9 years of work
reported the creation of a prototype battery that runs without a hub, but
the efficiency of which is 35,8%.
New uses for electricity generation several photo-absorbing layers, united
among themselves. The substrate is made of battery connections on the basis
of indium and gallium. The properties provided by the battery is quite close
to those used in the aerospace industry. Talking about the mass use will not
have developers in the coming years to address issues of cost reduction and
a number of technological problems.
Our company has gone a different way:
1. We left a substrate of mono silicon.
2. on the surface of the substrate of mono silicon, we have consistently
strike a few
layers of thickness 50-100 nano meter (materials that are applied is our
know-how) —
* Main layer of nano-size mono atomic amorphous silicon, is a very active
state of amorphous silicon. In this layer, the speed of motion of electrons
is several times higher than the standard Cell-based silicon. And as this
layer is able to convert into electrical energy is not only the visible part
of the spectrum of sunlight and ultra violet and infra red radiation. Mono
atomic amorphous silicon produced by quantum chemical engineering at a
temperature of 20 degrees Celsius.
Properties of mono atomic amorphous silicon are truly unique.
Cost to automobile 1 gr. This material does not exceed $ 100.
At the same time using 1 gr. mono amorphous silicon can cover 10 square
meter
photovoltaic plates.
* extreme layer is an anti-reflecting the carbon coating.
Total efficiencies achieved over 35%.
If you compare the cost of Sell-based mono silicon efficiency 16%
Cell produced by our technology with efficiency over 35%, our Sell more
10-15% while the efficiency of our Sell more than 2 times better.
While improving the technology and equipment we can achieve efficiency of
50% and above
.
The characteristics of our products:
Specification
Dimension :156mm x 156mm ± 0.5mm
Thickness :203 mc.m ± 0,5 mc.m, 180 mc.m ± 0,5 mc.m
Front :2.0 ± 0.1mm busbar (silver)
Silicon nitride antireflection coating
Back 3.0mm continuous soldering pads (silver)
Back surface field (aluminum)
Efficiency – 35%
Power : 6,5 watt
Color uniformity A, grade
In addition to the use of solar energy nanoscale mono atomic amorphous
silicon and its application of our technology has great prospect of
application in the electronics industry.
When applying this material for silicon-based chip, we seek to increase
speed and memory in the old scale of the chip.
We have plans to use this technology in other areas – space, medicine ..
To maintain the pace and timing of the completion of the production of
industrial prototypes we raise $ 3000 000.
We are interested in quickly attracting investment.
