Photovoltaic Modules
PV Today
Photovoltaic power can be produced in many ways, with widely varying
efficiency and costs. They can be divided into two basic groupings:
discrete cell technology and integrated thin film technology.
Cadmium Telluride (CdTe)
A thin-film polycrystalline material, deposited by electrodeposition,
spraying, and high-rate evaporation.Small laboratory devices approach
16-percent efficiency, with commercial-sized modules (7200-cm2) measured
at 8.34-percent (NREL-measured total-area) efficiency and production
modules at approximately 7 percent.
Dendritic web
A film of single-crystal silicon pulled from a crucible of molten silicon,
like a soap bubble, between two crystal dendrites. Gallium Arsenide (GaAs)
A III-V semiconductor material from which high-efficiency photovoltaic
cells are made, often used in concentrator systems and space power
systems. Research cell efficiencies greater than 25 percent under 1-sun
conditions, and nearly 28 percent under concentrated sunlight.
Multijunction cells based on GaAs and related III-V alloys have exceeded
30-percent efficiency.
Discrete Cell Technology
Single-crystal silicon
Sliced from single-crystal boles of grown silicon, these wafers/cells are
now cut as thin as 200 microns. Research cells have reached nearly
24-percent efficiency, with commercial modules of single-crystal cells
exceeding 15-percent.
Integrated Thin Film Technology
Copper Indium Diselenide (CuInSe2), or CIS
A thin-film polycrystalline material, which has reached a research
efficiency of 17.7 percent, delivers the highest completed module
efficiency for full sized power modules, reaching over 11 percent.
Amorphous Silicon (a-Si) Used mostly in consumer products for solar
watches and calculators, a-Si technology is also used in
building-integrated systems, replacing tinted glass with semi-transparent
modules. The primary issue with a-Si technology remains the low efficiency
and associated greater requirement for space and higher array installed
cost and weight
Multicrystalline silicon
Sliced from blocks of cast silicon, these wafers/cells are both less
expensive to manufacture and less efficient than single-crystal silicon
cells. Research cells approach 18-percent efficiency, and commercial
modules approach 14-percent efficiency.
Advantages of Photovoltaic Power
Photovoltaic solar power is one of the most promising renewable energy
sources in the world. Compared to nonrenewable sources such as coal, gas,
oil, and nuclear, the advantages are clear: it's totally non-polluting,
has no moving parts to break down, and does not require much maintenance.
A very important characteristic of photovoltaic power generation is that
it does not require a large scale installation to operate, as different
from conventional power generation stations. Power generators can be
installed in a DISTRIBUTED fashion, on each house or business or school,
using area that is already developed, and allowing individual users to
generate their own power, quietly and safely.
Rooftop power can be added as more homes or businesses are added to a
community, thereby allowing power generation to keep in step with growing
needs without having to overbuild generation capacity as is often the case
with conventional large scale power systems But even when photovoltaic
power is compared to other renewable energy sources such as wind power,
water power, and even solar thermal power, there are some obvious
advantages. First, wind and water power rely on turbines to turn
generators to produce electricity. Turbines and generators have moving
parts that can break down, that require maintenance, and are noisy. Even
solar thermal energy needs a turbine or other mechanical device to change
the heat energy of the sun into mechanical energy for a generator to
produce electric power. Photovoltaic power, by contrast, is generated
directly from the sun. PV systems have no moving parts, require virtually
no maintenance, and have cells that last for decades.
Uses of Solar
How practical is solar for home and mobile home/marine use? These days,
it's pretty practical, especially for remote homes. Until solar power came
along, people who wanted to live in remote areas frequently had to pay
large fees to have a power cable run to their house. Now, a remote home
can be virtually self-sufficient with solar power. Even in areas where
power lines are nearby, solar may be a viable alternative to being
connected to a power company. An average home has more than enough roof
area to produce enough solar electricrity to supply all of its power
needs. With an inverter, which converts direct current (DC) power from the
solar cells to alternating current (AC), which is what most home
appliances run on, a solar home can look and operate very much like a home
that is connected to a power line. For recreational vehicles, solar power
provides the freedom to go to more remote locations, without relying on a
plug-in power source or a noisy electric generator. Systems for RVs can be
small for charging batteries only or large enough to power the entire
vehicle for a period of time. Similarly, boats can use solar power for
many of their power needs, rather than a generator or engine.
Solar PV Power in Industry
Some of the most important applications of solar energy are nearly
invisible.
Telecommunications, oil companies, and highway safety equipment all rely
on solar power for dependable, constant power, far from any power lines.
Call Boxes: look at any California roadside call box, and you'll see a
solar panel. California standardized on the use of solar power and
cellular phones to eliminate the need for any buried cable connections to
these phones. Given the sometimes literally life-saving nature of these
call boxes, dependability is a must.
Roadside signs: solar power is used for many lighted highway signs,
eliminating the need for diesel generators.
Telecommunications installations: when you need a microwave repeater on a
remote mountaintop, the last thing you want to do is run a power line up
to it. For reliable power, many communications repeaters in remote areas
use solar.
Siemens Solar alone has shipped over 130 megawatts of modules since its
inception, and the use of solar power is projected to grow at 10-15% per
year from now until the year 2010. This is over three to five times the
rate of growth of the Gross National Product of the United States!
Given this growth, solar power will be a much larger part of our lives in
2010 than it is today. Homes could incorporate solar power at the time
that they are built, dramatically reducing both the cost of buying solar
power and the cost of utility bills. New communications technology may
make living in remote areas a practical reality given the availability of
solar power. Mobile uses will undoubtedly increase. And industrial
applications will continue to enjoy the versatility of solar power

dioxide emissions will be reduced.
Reducing glare to increase visibility.
Glare from street lights is significantly
reduced with the new IQ LED's street-light
fixtures, increasing visibility by directing
light onto the roadway and preventing it from
shining into the eyes of motorists.
Reduce excessive lighting and light
pollution. New ways of designing and
providing street lighting have been developed in
the last several years.
Maintaining a safe level of lighting. Street
lighting on residential and collector roads will
continue to meet minimum Illuminating

Increase the public safety and reduced traffic congestion by
 allowing
traffic lights to function even during a power failure. A
typical traffic signal intersection experiences eight to ten local
power outages annually. With IQUPS battery backup power, some or all
the traffic control signals can continue to operate. This seamless
switchover to battery power increases public safety and eliminates
the need to dispatch police or other service personnel to direct
traffic. If all traffic signals were converted to LEDs, the battery
backup system would allow full operation of the traffic signals
during a power outage, thus alleviating traffic congestion.
