This is incredible information on the alternate source of energy. I am amazed with the kind of information you guyz have collected. Offshore windmills is in nascent stage. This has been tried in the Scandinavian countries, I have seen during my visits. It is an expensive proposition I believe. I have on business visits to Madras met some of the companies. they are doing a great work.

Everyone would remember SUZLON, at least they claim to be world leaders this was marketed very well and they were visible. Unfortunately Like Madras city which is not marketed well, many business concepts that were conceptualized in TN have never been hyped or marketed well. Viz Spencers Plaza, Saravanas (one opp to Panagal Park) Kishore Biyani seems to have picked this idea of large format stores from Saravanas and dared to dream big and made it happen. Andwhereas Saravanas or other big chains never ventured out of TN. Alternate energy is the future and like how Karnataka promoted Bangalore as Silicon Valley (inspite of the pathetic infrastructure) TN government should leave aside the politics and promote the CITY as a world class one - in the making. Mayor should be vested with powers and a Bloomberg of NY city should evolve in Madras city.

Anyways great going, good luck

You can look into TN renewable energy thread too. That has a lot of info

Initial setup cost will be higher for solar systems , Just for an example a 6ft by 3 ft solar thermal collector (Flat type ) which will produce a temperature increase of around 100 degree Celsius would cost 10,000 R.s ... This will be sufficient just to heat water to around 90 degree celcius(Considering all losses) ..

Give me sometime i will bring up a small calculation for specific amount of power production ... Also the solar heat incidence depends on various factors like
*time of the year
* Position of the sun
*distance from equator
etc.,

Yes and No. Correct me if I am wrong. I think that the technology in that area advanced enough nowadays to overcome those limitations (like employing solar tracker to track the sun, using effective reflector solutions to reflect the light back etc.,)

Its Biyani, not Biriyani(neengalum quarter & kozhi biriyani case ah ). Biyani owns the Future group(which has brands including Pantaloons)..

We have been trying for a large solar panel park in TN for the last 2 years but the land cost is very high compared to other states.

The Govt is considering this as a real estate project.

The initial establishment cost is also very high and both Central & state Govts should implement some new TAX SOPs.

Moser Baer & Signet Solar projects are also not progressing much due to the lethargy.

Now it is up to the next Govt in TN.

Recently, a 1 MW Solar park was synchronised with grid at Sivagangai. Our member Blackpearl has been saying that land cost around Ottapidaram,Ettyapuram,Thapathi etc is quite low and density of population is low. Being a dry area, you may have a great chance to set up a park.

Fix up and get started...

India Budget Disappoints Renewable Energy Sector, Gamesa Says

http://www.bloomberg.com/news/2011-0...mesa-says.html

Ramesh Kymal, chairman of the Indian unit of Gamesa Corp Tecnologica SA, Spain’s largest wind-turbine maker, said India’s proposed budget for the fiscal year starting April 1 is a disappointment to the renewable energy industry.

Finance Minister Pranab Mukherjee presented the budget today, which will be put to vote in parliament. Kymal, chairman of Gamesa Wind Turbines (India), said in Chennai:

I am “disappointed with the lack of aggression and support for the renewable energy sector. India pays a huge fuel subsidy. We are doing nothing for renewable energy sector and continue to subsidize oil and coal, which is not good in the long term.

‘‘Ultimately, it will impact the Indian economy. India cannot achieve 9 percent gross domestic product growth unless we address the energy problems of the country.’’

That is 5 MW power plant not 1 MW.. http://www.moserbaerprojects.com/sol...p?links=sp4#b2

Like Leo said, Sivaganga district and other semi arid regions located on the wayward area of western ghats (the settings of a typical Bharathiraja film) will be your best bet. How much area will be required for setting up a solar plant?

you got me wrong ... I was referring the factors which affect the average solar incidence on a particular region or city ..
See the solar radiation on earth day per day is 1386 W/sq.m which will not be same at all places

* The solar energy at dawn and dusk per sq.m will be less and during midday will be high...
*Similarly 1386 is the average value , Chennai will have its own energy incidence value and Delhi will have its own value .Which u have to determine using those factors
*And the solar tracker which u mentioned is for effectively capturing whatever is available till the sun disappears , it cannot provide or boost more than what u get there..(Am considering one collector here)
*This calculated energy incidence in that region will give you a fair idea (without other energy losses) how much solar power u can siphon out from that region...
* In fact the most effective parabolic or dish solar heat collectors even now are having So much of conduction energy loses

Vestas opens Chennai wind power facility (Additional news link...)

Snippets :

Quote:
The test centre will generate more “green jobs” locally in Chennai, where employees research on competitive answers to combat CO2 emissions and rapidly growing huge energy needs of India. In addition to the opening of the test centre, Vestas Technology R&D is also expanding its existing office space at Chennai by an additional 35,000 square feet.
Quote:
Established in August 2007, Vestas Technology R&D in Chennai is the largest Technology R&D centre for wind energy in India and it employs over 300 specialists in Chennai who carry out cutting edge R&D into all aspects of wind turbine engineering and design.

Hmm!! What about CPV? (Concentrated Photovoltaic Trackers). I was under the impression that it could even capture the diffused light from sun. When we are talking about capturing diffused light, intensity of light radiation doesn't really matter OR does it? Don't know. (Especially when used / combined with reflectors). Got to read a bit more. Just thinking out loud

Googled a bit and found this in Wiki. I guess that whatever darkprinz said are important and ideal for economical reasons, but still technologically feasible with far-from-ideal conditions.

Sun path refers to the apparent significant seasonal-and-hourly positional changes of the sun (and length of daylight) as the Earth rotates, and orbits around the sun. The relative position of the sun is a major factor in the heat gain of buildings and in the performance of solar energy systems[1]. Accurate location-specific knowledge of sun path and climatic conditions is essential for economic decisions about solar collector area, orientation, landscaping, summer shading, and the cost-effective use of solar trackers.

Yes you are right that PV cell has the ability to WORK under diffused light conditions unlike Solar Heat cells , but it is less efficient compared to the former ..I repeat it can work on both direct and diffuse light radiation but it cannot capture energy as efficiently as Heat collectors or heat cells ...

Thats because for heat cells both light and heat energy of sun rays are contributors which is not the case in PV cells ... In fact PV cell's performance reduces as the Temperature of the collector surface increases ..In future we have to combine and form a new technology where the efficient energy capturing of Heat cells (i.e all bands of spectrum) and also property of working in diffused lighting conditions as in PV cells are present

But as you say no one is expert here ... But renewable energy is one hell of an interesting topic to read and discuss ... all my college projects were based on renewable energy only

common kannan, land cost is a fraction of total solar park. even with lower efficient (& lower cost) thin films, you shouldn't need any more than 20 acres/mw. mw costs about 20 crores. that translates into 1 crore/acre. land at even 10 lacs/acre would only be a marginal cost and such land is available at many places with good grid connectivity.

ping me if you still require land. we can help you with large tracts of lands near kayattar: i think it is a class 2a wind site with sub-station nearby where you should be able to additionally put up solar park as well. these are all dry areas, so i would think solar insolation levels should also be very good.
