Renewable Solar and Wind
Alternative Renewable Energy
Proposal For The
Southern and Eastern African
This proposal has been initiated by n-Trading a subsidiary of NWorks Group in
collaboration with Solarin Holdings introducing one of the most significant and
exciting renewable energy ever proposed in Southern and Eastern Africa. At the
heart of this initiative, in light to
• Global warming which is causing a rise in sea levels, and leading to a loss
of coastal wetlands, erosion of shorelines, increased flooding in coastal
areas, Local and regional climate shifts also having severe impacts on
ecosystems and agriculture.
• Increase in demand and rising costs of energy in Africa as a whole.
N-Trading is proposing the use of Solar and Wind powered applications as an
alternative to supplement the already existing traditional Hydro-electric, Nuclear,
Thermal, Bio-Based systems. Economic development is closely related to the
development of energy. Current energy supplies provided in Africa as a whole
are associated with emissions which cause local, regional, and global
environmental problems. Projections indicate that Africa’s energy demand will
increase dramatically thus, there’s need for effective, efficient sustainable energy
usage to contribute towards reducing adverse environmental impacts whilst
moderating on the growth of energy demand.
This initiative proposes solutions which ensure energy demands are met whilst
achieving a huge cost saving in the import of energy as well as contributing
significantly towards both the governments’ renewable energy targets and easing
the global climate challenge. In addition, extensive application of Solarin’s
innovative products and solutions which emphasize on sustainability
consequently helps in making that real difference to people’s lives.
Solar and Wind applications can play a very important role in helping to meet
basic energy needs in various sectors and fields through the use of modern
innovative technologies. Solarin’s products and solutions for example have a
wide spectrum of applications spanning Domestic and Home, Industry and
Commerce, Military and Civic, Private and Public, Agriculture, Energy Utility
companies, Mobile, Portable, and Automobile.
The Alternative Energy Revolution
Oil has been such a powerful lynch pin that it is hard to believe that its days of
prominence maybe waning, but as demand for oil steadily increases and supplies
are consumed, oil is in the fall of its life. In its place several array of technologies
in the form of alternative energies exist. Wind and Solar as part of the emerging
technologies of fuel cells and energy storage, the prospects over the long-term
are bright. In short the Alternative revolution is underway. Worldwide economic
growth is creating new pressures on conventional fuels that cant be met entirely
by traditional energy sources. It’s hard to argue with the data. For example, In
2004 – worldwide energy consumption grew by 4.3% - a new annual record in
volume terms. Oil consumption was 3.4% - the fastest increase since 1978. And
2004 was no freak occurrence. Agencies such as International Energy (IEA)
predict a world-wide increase of over 50 % in primary energy demand in the next
20 or so years. When these statistics are broken down by region it becomes
clear just how much more of it African nations need. Further to this just as growth
in energy demand is accelerating, Africa is starting to face the prospects of
limited production capacity. There’s a clear link between development and
soaring global energy demand. But where will this energy come from?
Despite several barriers and challenges in the adoption of renewable energy
technologies just to mention a few which include
• Economic and financial,
• Awareness and Informational,
• Institutional and policy.
Considerable solutions exist. In brief, economic and financial challenges can be
tackled through active participation of the government, non-governmental
organizations, donors, and banking and finance (credit facilities with low interest
rates). Awareness and informational challenges can be tackled through effective
public awareness and promotional programs. Technical challenges can be
tackled through revising current manufacturing standards, specifications to
include quality control and installation requirements.
n-Trading (in collaboration with Solarin Holdings) has a Vision of empowering
African nations with innovative renewable energy solutions ultimately satisfying
the growing needs of citizens within as well as developing their social and
economic quality of life.
Our vision means… being involved in promoting and ensuring extensive use of
renewable energy applications and technologies as an alternative to supplement
the growing global challenge. As a new player in the chain of advocacy and
distribution of renewable energy applications we strive to work in synergy with
players in various fields, industries, and sectors to provide cost effective
solutions. These products and solutions are tailored to suit the needs of varied
clientele which stretches across a wide spectrum of private and public users such

Are the qualities and efficacy of the Hybrid System Certified?
Yes, by many renowned international bodies.
What is Solar and Wind Hybrid System?
Solar and Wind Hybrid Generator is a system that works by converting solar & wind energy
into electrical energy. A hybrid system uses a combination of solar panels (to absorb
sunlight) and wind turbines (to convert wind to electrical energy). Electrical energy
converted is the stored in a deep cycle battery to ensure continuous use. However an
inverter exists to convert DC power stored in the to AC. The hybrid system supplements
cloud and no-wind days. It can be used to power your house, business, institution, and
organization. Such a system is very useful in the event of a power failure and works in
conjunction with the utility grid.
Typical Solar and Wind Hybrid System Constituents

THE NEW YORK RAILWAY STATION
For many years, solar energy has been the
power supply of choice for industrial applications,
where power is required at remote locations. This
means in these applications that solar power is
economic, without subsidy. Most systems in
individual uses require a few kilowatts of power.
The examples are powering repeater stations for
microwave, TV and radio, telemetry and radio
Solar energy is also frequently used on
transportation signaling e.g. offshore navigation
buoys, lighthouses, aircraft warning lights on
pylons or structures, and increasingly in road
traffic warning signals. Solar is used to power
environmental and situation monitoring
equipment and corrosion protection systems
( based on impressing a current ) for pipelines,
well heads and bridges or other structures. As
before, for larger electrical loads it can be cost
effective to configure a hybrid power system that
can link the PV with a small diesel generator.
Solar greatest benefit here is that it is highly
reliable and requires little maintenance so it’s
ideal in places that are hard to get to.
Our design is free electricity to illuminate the billboard, the best applications for solar-
powered signs are in remote or inaccessible locations, the middle of a public highway where
you desire lighting without the expense of a new wiring feed. One example is a post-
mounted, directional sign that's installed near a highway junction. Also, signs on medians,
traffic islands, or at entrances to towns or residential developments may be cut off from
standard power sources. Another situation is an old sign or pole with faulty underground
wiring that can't be re-pulled. In this case, the cost to install new conduit and wiring across a
long, paved area might be prohibitive. These are situations where solar-powered lighting
provides cost-effective solutions. A nearby solar panel generates electricity and charges the
batteries inside the sign. The batteries are connected to 35-watt HID light to operate the
tubing. According to experiments, given the power limitations of solar systems, HID is a better
choice for internal sign lighting because it consumes less power than fluorescent lamps.
