solar power generation -need of the hour?

[karthi1000]

hello fellow mem
there is only 10/24 hrs eb supply in tamil nadu:clapping:
any valuable suggestions regarding solar power generation @ 20 units /day welcome !

i dont think solar is the answer. night time no sun
you need to store the energy in batteries and to be able to run whole night, you will loads of batteries.

Power situation is very bad in Tamilnadu....I stay very close to chennai ( Tiruvallur).. Even i am victim of power cuts 12/24 Hrs...

Look @ the solar inverters.....They are no specific brands that i have heard of..

But they are real expensive even after subsidy by Govt of India...I did check the option of getting them..But to produce 850VA, the setup is 40K (Including the solar panels).....It is an one time cost, also you get 10 yrs warranty on the solar panel...But not sure if the company will last that many days hyeah:....

Solar power at a mega scale only makes sense ... say, upwards of 50 MW. This too is pretty expensive, since for each MW generation a capital outlay of Rs. 12 crore is required vis a vis thermal route @ Rs. 4 crores per MW. The solar obviously 'tries' to payback due to no-fuel requirement. This is the present costing, which would invariably come down with more players entering this field and mass panel production planned. If the capital outlay drops to @ Rs. 7 to 8 crores/MW, then solar power generation gets in the 'black' without the subsidies.

Thanx for the info mate..but what about maintenance aspect of solar panels? I think that's where they fail in the long term, causing solar power to remain untapped this long?

So far, I have heard of SuKam and Goodsun. My wife called some Chennai Sukam guy, who said solar inverter was 35,000 for 80w. He didn't want to tell any more unless we went to his shop .

At least through the winter months I can get through the day with my PC and a fan. Light and fan comes from an inverter that we already have. My PC draws 150W. How can I support that, and how much will it cost for reliable equipment? Is there really any subsidy on this stuff? Does it make much difference?

I already have a solar water heater. At the time I felt I had money to spare on gadgets: it was a luxury, convenience buy, and will never, ever pay for itself in fuel savings. Same is true for solar power, I'm sure: it would take a decade or two to pay for itself, and the kit won't last that long anyway.

Any comments on specific solutions, providers, costs, etc, would be most welcome...

Well you folks in TN have a new Nuke power plant coming up.
Won't the situation improve?

 

[avidyarthy]

Solar power remained untapped JUST due to payback issues and initial capital requirements. Everything that we use, run, operate and see on day-to-date life is due to their commercial viability ... and nothing else. Technology has to prove its worth in commercials first, that means, lesser cost in setting-up as well as lesser cost during operation .. the time line of whose payback cannot be more than 4 years, else, it is deemed to be not viable, no matter how great the technology is.

We are talking here of the solar-thermal route and not the solar photo-voltaic. Maintenance though required, is not a deal breaker in here. It is manageable.

I know this is not the kind of expected response, but how about we stop generating more humans? Specially more than 1 human per family?

We all talk about problems. None of us want to get into its root. In the root of all our problems is (1) Illiteracy and (2) Population.

If we don't mend our ways, by 2020 we will have acute shortage of

• Energy
  • Electricity
  • Cooking gas
  • Petrol/diesel
• Drinking Water
• Educational Institution (we already are in lack of)
• Food (by 2025)

Please conserve water. Please ride a bicycle/electric bike to work. Please don't dispose your stuff in Ganges/Yamuna/Kaveri. Please go shopping with a cloth bag (like our ancestors used to do). Give up the temptation of following the west and carrying around shiny plastic bags.

Right now it's only about electricity. In coming years it will be every natural resource. We Indians will be the front line sufferers due to our population overload and our government's failure to prevent further damage.

Don't fall victim to marketing. Please Reduce, Reuse, Recycle.

Our ancestors gave us a world with enough food to eat, enough water to drink. What are we going to leave for our coming generations?

Reduce, Reuse, Recycle.

Save the World.

Another issue with solar and other non conventional power sources is the lack of efficient battery technology and battery disposal. The financial and environmental cost presented by the mass use of batteries as a storage medium is something people forget. Majority of the batteries we use are still based on decades old concepts. Newer higher efficiency batteries either cost a fortune or are impossible to source without a lot of effort.

 

[iaudio]

The main issue is to use stuff like AC etc which are a pretty heavy load with solar backup. Even then using solar panels instead of your main supply to charge your inverter battery, would reduce consumption quite a bit.
The cost of panels is coming down steadily,but it still has a long way to go. Coimbatore seems to be a hub for solar panel manufacturers. Is that so?

Another reason why I think Indians need to stop being ignorant and start accepting non heterosexuality so every single man and woman isnt forced into a marriage and expected to produce children - in regards to how to not have more than 1 child per family.

 

[ranjeetrain]

Outside the Muslim world, India has the strongest family tradition. While it is great in many ways, it is counterproductive in the way that it encourages people to have more children. A nuclear family cannot have enough time to raise more than 2 children responsibly.

I just hope Indians wake up before it's too late.

you are right, it will be too costly to make a system that can run the higher Kw stuff like AC.
A reasonable(affordable) system will be an 800W inverter(means only one 12v battery needed) with 200W-300W panel(say even at 1$ /w it will be around 16k for panel and similar amount for battery and inv ).This can run other lower W stuff like lighting/fan/fridge/tv etc which runs for long duration.

the solar panel will share the load and charge batteries,if you can afford you can have increase the panel capacity so as to reduce the dependancy on grid

There is a govt scheme already in place, MNRE or something which give 30% odd subsidy


I have seen the panel cost came down quite a bit now around 0.7$/W for the high efficiency mono crystalline panels(for high volumes ofcourse)

government need to promote rooftop panels with grid tied inverters in every home where the consumer can sell back/(or adjust against the bill) the electricity produced during the day

as the demand for panels increase their cost will comedown

About a year ago I had a talk with an entrepreneur who was planning a setup of a plant to manufacture one of the modules in the solar power source and according to him the conventional electric dept and the relative ministry has a big role in delaying the cost of solar energy source equipment especially the panel!!

panel manufacturers all over the world are shutting shop due to the chinese invasion ;-) moser baer the largest solar panel manufacturer in india is having problems. i had also been looking to setup a 5mw solar PV module mfg unit in tech collaboration with sunsolarUSA but cudnt raise funds.

there is no doubt that solarpower is a good choice for india but hopefully in a few years time we will have further cost reductions in solar panels and we can have rooftop solar systems all over india.

 

[rud3dawg]

The Govt cannot afford to let this source of revenue go out of its hands I feel.. Hate the fact that such vast abundant source is still untap~able in India... Thanks to some very selfish people am sure!!

 

[naveenjn]

There is a solar power project for homes, subsidized by the Government. The initial cost is about Rs 2.3 lakhs. Central Govt will refund Rs. 81,000 or 30% of the cost of power plant (whichever is less) after installation. In Kerala, state government is also offering a subsidy of Rs. 39,000 for the same project. But all these subsidies will be provided only after installation which costs 2.3 lakhs. And since it is Government matter, the subsidies could take a long time.

Once installed, the system will produce and store up to 4 units (depending on the weather) of electricity daily. You can find more details of the project at the website of ANERT.

^^^
The rate of Rs.2.30 Lakhs for one KVA setup is too much in my opinion. The government shall instead offer the solar panels at subsidized rates, rather than encouraging integrators. It is said that solar panels are available in the international market at the rate of one dollar per watt. In ebay, panels are available at Rs.100/ per watt. Even taking this cost, the panel it self costs only one Lakh rupees. The rest of 1.30 Lakhs is for the structurals, charge controllers and the battery backup. If the panels are made available at Rs.50 per watt or lower, the people will buy them and will find innovative and cheaper way to use them.

One thing in my mind is that a large number of houses already have UPSs and inverters. If they are made chargeable using the solar panels, a lot of cost can be saved. But the government sponsored schemes have no option in this regard.

I have been thinking of solar solution for some time and have a generic question.

Lets say we use more panels and use the power for whatever we can during day, and keep the backup to a min requirement of lighting and fans like a inverter and utilize grid power when it is available at night, wont it work well? I know there maybe be some waste during the day as we may not use it and nor can we sell it to grid, but trying to store it would be very costly too. This may require a device which can utilize max power from solar and delta from grid.
