| Why
Solar Power? |
| |
| The
answer is simple Safety, Health & Environment. |
| |
| Free
and Clean electricity from the Sun would appear
to be the future power of our generation.
Now solar photovoltaic modules are available
at much lower prices then ever before, it
would be cheaper to obtain electricity directly
from the sun. This is especially the case
for Pakistan, which has the advantage of unlimited
sunshine all the year around. |
| |
| With
such abundant sunshine we should be using
Solar powered Traffic lights (No more traffic
jams every time when there is a power cut).
Solar powered display stands, Solar powered
billboards, Solar highway lights, Solar streetlights,
Mobile Phone solar charges, Solar Home Light
Systems and many more applications. |
| |
| Each
stand-alone, Solar electricity generating
system can provide power for up to 24 hour
a day. Solar lights can be designed to provide
illumination automatically from dusk to dawn.
Each system can charge itself, store and produce
electricity even on dull days. |
|
 |
 |
|
| |
| Recreation
parks and gardens Solar powered lights are safer if as
they operate at 12V DC. At this voltage there is no danger
of electro-caution, a most beneficial safety feature in
places frequented by children. |
| |
| Moreover
Solar powered lights can be installed almost anywhere:
in rugged terrain, offshore, in remote areas where electricity
is needed but not available. |
| |
| Solar
power is now used for outlying telecommunication relay
towers, remote sensing equipment, aircraft warning lights
on pylons. |
| |

| Advantages
of Solar Powered Equipment |
| |
- No bills to pay
Buy solar powered equipment and after that your electricity
is free.
- Minimal or no maintenance
Solar Panels are guaranteed for 15years and the Deep
Cycle batteries for 5years.
- Standalone
Streetlights can be easily relocated and any occurrence
of accidents or failure will not affect the others
- No Power Failure
No fear of Fluctuation, Power failure and load shadings.
- Cost Effective
In areas where the National Grid is not available.
Solar Power Products have a clear advantage. There
will be no cabling costs, no need for substations,
which are very costly to put up.
- Auto on / off Sensors
No manual operation required to on / off lights
- Security and CCTV Equipments
Run Electronic Security Systems and CCTV Cameras independently
with Real Wireless Solar Power.
- After Sale Support readily available
As Mondial is a local company, there is no undue need
to wait for spare parts.

| |
| So
be environmentally friendly, save money and be first into
the future with Solar Power. It even runs on Pakistani
Sunshine. |
| |
| Specialised
Lighting System. |
| |
| Mondial
has developed its own lighting system. A normal incandescent
light bulb loses 90% of the power you put into it, in
the form of heat. (Just touch a light bulb and see how
hot it is). The new energy saving fluorescent lamps, still
need heated cathodes to work and also two-third energy
in heating the cathodes. Mondial uses a cold cathode tube
for lighting. This is much more efficient. |

| |
| What
to look for in a Solar power system |
| |
| Overview
the checklist |
| |
| For
a good solar power system you need: |
| |
- A solar panel to produce electricity.
- Correct installation of the panel to obtain full
output.
- A Solar power controller to protect and care for
the rest of the circuits.
- Power output either a 240-volt inverter or direct
DC out.
- A 240-volt inverter loses 30% power in the
conversion process. (Use 12V DC wherever possible
to save this loss)
- Change to 12-volt systems if possible, to save
costs.
- Solar power storage. Non liquid, Deep cycle, solar
batteries.
- Use a company that knows about solar power and
knows how to install it.

| The Solar
Panels |
| |
| This
is the major part that catches the sunshine and converts
it into electricity. This is a simple process. DC; Electricity,
is only a stream of electrons, moving along a wire or
conductor. To make electrons move in one direction. The
Solar panel is coated with silicon. Silicon allows electrons
to travel through it, in only one direction and will not
allow electrons to go back the other way. When electrons
are under the sun they absorb energy , becoming excited,
and begin to move in all directions. Because they are
in the silicon , they get stopped in one direction, but
manage to move freely in the other direction. Once they
are moving, all in the same direction, we have the electricity. |

|
| |
| One
can choose between amorphous and mono crystalline Panels. |
| |
| Amorphous
Panels |
Crystalline
panels |
| Still produce
electricity if any part of the panels is in the
sunlight. |
Will not produce
power if even a small area is shaded. |
| Work at reduced
levels even is cloudy weather. |
Drop their
output to zero in cloudy conditions. |
| Work even
at very high temperatures, e.g. 75 degree C |
Show a larger
voltage drop at high temperatures. |
| Cheaper than
crystalline Panels. |
More expensive
than amorphous panels. |
