3. Solar Energy

4. Solar Tree
TREE stands for
T=Tree Generating
R=Renewable
E=Energy and
E=Electricity

5. Components of Solar tree
 Solar panels.
 Long tower.
 Batteries.
 LEDs.
 Stems for connecting the panels.

6. Working of a Solar panel
 Solar cells produce direct
current, or DC, this DC current
is converted to alternating
current, or AC by using
inverter.

7. Working of Solar Trees
• The Solar Tree panels charge batteries during
the day.
• At dusk the Solar Tree automatically turns
on LEDs.
• The internal control can also regulate the
amount of light produced depending on how
much charge is left in the batteries.
• And moreover, the energy stored in the
batteries can be used for other purposes also.

8. Spiralling Phyllataxy
is a technique
used in designing of Solar Tree. For
tracking maximum power from sun.

9. Fibonacci pattern for solar trees
• “The can
improve solar panel arrays in
several ways. It collects more
sunlight when the sun is at a low
angle in the sky. This is useful
during winter months and in
extreme latitudes”

10. Examples of Solar Trees

11. World’s Largest Solar Tree
Produces 8.6 KW of energy.
 The system will offset up to 10
tons of CO2 per year from coal-
fired power plants.
The system will generate 10,000
kWh’s per year, about ½ of the
annual electricity needs for the
Tourism London building at 696
Wellington Rd.

12. Solar panel Vs Solar tree
• 2MW -> 10-12 Acres • 2MW -> 0.10-0.12 Acres

13. Applications
Street lights.
Industrial power supply.
House supply.
Deforested areas.
Urban and Rural.
Recreational parks, city parks.
Airports.

14. Advantages
• “Solar tree is the successful marriage of most advanced technology i.e., grabbing the electrical
power or energy through a great ease.”
