4. Simulink is a data flow graphical programming
language tool for modeling, simulating and
analyzing.

5. • Areas of precision
• More efficient, flexible and more faster
• Capacity for quick iteration

6. The amount of incident energy per
unit area and day depends on a
number of factors, e.g.
* Latitude
* Local climate
* Season of the year
* Direction of the sun.

7. Active solar technologies:
 Water Pumping
 Solar powered watches
 calculators, and cameras
Passive solar techniques:
 Designing spaces that naturally circulate air
 Referencing the position of a building to the Sun
 Telecommunications

9. PV panels provide clean – green energy
Solar energy is free and abundant!
Solar Panels cost is currently on a fast reducing
track and is expected to continue
PV panels have no mechanically moving parts,
except sun-tracking mechanical base
Reduce pollution
The most important aspect of PV panel is the
positive effect on the environment

10. If weather is cloudy or rainy then it doesn’t
work.
Initial setup cost is high.
Solar energy panels require additional
equipment
Power efficiency is low

12. • Photons reach emitter layer
• Energy releases electrons from
silicon
• Electrons (-) are attracted to
base region (+)
• Holes (+) in the base are then
attracted to emitter region
• This is a flow of electricity
• Electricity will flow through the
two contacts
• Same principle as a diode
