Solar TreeTREE stands for

T=Tree Generating R=Renewable E=Energy and E=Electricity

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

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.

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.

Spiralling Phyllataxy• “Spiraling phyllataxy” is a

technique used in designing of Solar Tree. For tracking maximum power from sun.

Fibonacci pattern for solar trees• “The Fibonacci pattern

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”

Ross Love grove's Solar Tree

Spotlight Solar product "Lift" at net-zero school in NC, Sandy Grove Middle School

World’s Largest Solar TreeProduces 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. 

Solar panel Vs Solar treeTraditional PV solar

System

• 2MW -> 10-12 Acres

Solar tree

• 2MW -> 0.10-0.12 Acres

ApplicationsStreet lights.Industrial power supply.House supply.Deforested areas.Urban and Rural.Recreational parks, city parks.Airports.

Advantages• “Solar tree is the successful marriage of

most advanced technology i.e., grabbing the electrical power or energy through a great

ease.”
