Though the news above isn't in English, but in it, it has been said that what can be produced by a solar panel of 500 sq foot area can be produced by a solar tree that will take just 9 sq foot. I want to know how solar trees can produce the same amount of power with just less than 2% of the area in comparison to a solar panel.

That does sound like a stretch. I think it's hype.

I think they're talking about area of ground space required for solar panels. Their design has a vertical tower mount (the tree) so that more panels can be mounted in the same footprint.

Here's the Google 'Translate' version:

"Solar panels were used to produce solar power so long. This time the solar tree can be seen in the state. Every day 5 kW of electricity is available from a tree. Not only financially, this kind of 'solar tree' will help in the environment and beauty of the city to build Green City. As the model, the first solar plant in Kolkata will be set up in a park in south Kolkata - said electricity minister Sobhanadev Chatterjee. Seeing the success of the state, the electricity department will be encouraged to put it elsewhere.
What will be the solar tree?
The Central Institute of Mechanical Engineering Research Institute (CMERI) has developed the design of Solar Plants received from Central Government. Based on this design, the tree has been created by the Center's licensed agency. It has been installed in more than one place in Delhi. According to the state power office sources, there are 20 solar panels in the solar tree, just as there are stalks in the tree. Each panel will have a total of 5 kW of daily production capacity as 250 watts of trees. The height of a solar tree will be 25 to 30 feet. But the panels will be fitted with three layers of ground 12 feet above the ground, so that any work can be done at the beginning of the tree.
What is the advantage of installing solar plants than the panel?
In the words of the Power Minister, "Experts have said that at least 500 sqft of space is required to install 5 kilowatt solar power panels. But for a single solar tree with the same capacity, only 9 square feet is needed. "Besides, the size of the tree is also attractive. Sobhanbabu said, the manufacturer said that the tree will be standing in one place (the panels eastward). Then there is a plan to rotate it. He can keep his light all the time until the sun sets. The minister said, the electricity that will be available every day from the solar plant will be much less."

I have some doubt about the explanation as rooftop solar panels don't need any kind of "extra space" in that sense. And if common solar cells are mounted in poles, that too will have the same effect.

English language version.

“The challenge was to come up with a design so as to generate more solar power in less land space,”

It is a solar array on a stick.

In high latitudes it could make a lot of sense.

Here is a picture are 20 Solar Panels that use only 8 Square Feet of land space ...

It has two poles, each pole uses only 4 Square Feet.

What's the point? The 27 PV panels and the thermal collector on the roof of my house use ZERO land space.  Now if there was a deck or parking area under the array I could see it.

By solar "tree", I'd visualize something like this, but the panels would have to be mounted so they did not shade each other in the summer. The pole might rotate to follow the sun, too.

(not too sure how well they'd hold up in a Florida hurricane though)

Revi, With all due respect, I have to say that your question is nonsensical.. The generating area is the area of incident sunshine swept by the panels and has nothing to do with the ground area the 'tree' occupies.

Take a look at the picture that accompanies the article, they have just stuck many standard solar panels on a pole!

Here are 45 off 250w panels on a dual axis tracker in Kamloops, BC, Canada (near me) . = 11250W of generation, with, using the article author's way of describing facts (alternative truth?  ;-) ) a foot print of 25sq ft ( the base is a concrete mass pour 5ft by 5ft)..
