The document discusses the importance of reducing greenhouse gas emissions and highlights solar panels as a sustainable energy alternative. It categorizes three types of solar panels: mono-crystalline, polycrystalline, and amorphous, each varying in efficiency, cost, and application. Mono-crystalline panels are the most efficient and costly, polycrystalline panels are durable and affordable, while amorphous panels are the least efficient but suited for residential use.

1. Solar Panel Types – Which One Do you
Prefer

2. An Insight into Green House
Gas
The International Panel on Climate
Change has warned that green
house gas emissions must be cut to
avoid the dangerous effects of
global warming.
But do we really follow IPCC? Not
right? Want to join hands with
IPCC?
Use less energy and find alternative
energy sources. One of the
alternatives is using solar panel
which is sustainable and never run
out. They are also seen as “green”
energies, because they don’t
directly produce green house gases.

3. Types of Solar Panels
 Mono-crystalline Solar Panels
 Polycrystalline Solar Panels
 Amorphous Solar Panels

4. Mono-crystalline Solar Panels
• Mono-crystalline panels are
the most efficient one
because they are made of
highest grade of silicon and
require least amount of roof
space.
• They generate the highest
power output. It have a
return electricity rate of 14%
to 18%.
• At the same time, it is more
expensive compared to
other solar panels.

5. Polycrystalline Solar Panels
• Polycrystalline solar panels are
less efficient than mono-
crystalline as they are formed by
placing liquid silicone resulting
into an ingot.
• They have an electricity return
rate of about 12% to 14% and are
less efficient than mono-
crystalline.
• Polycrystalline are cheapest solar
panels and require low
maintenance. The best part about
polycrystalline is its durability
i.e. it lasts for 25 years or longer.

6. Amorphous Solar Panels
• Amorphous solar panels come
in a film which is deposited on
substrates such as metal, glass
and plastic. This type is
relatively new to the market.
• It has the lowest electricity
return rate of between 5% - 6%.
• They are cheap but its
installation is expensive. This
type is best suited for
residential buildings as they
are largely unaffected by
weather conditions or higher
temperatures.
