Solar Power

Is it wise to go in for solar power in our homes?

Dear Sri"Sundachu",

Certainly solar power is one option for the alternative energy. I have seen Solar power being generated and used in Navadarshanam Community near Anekkal-Tally border. My friend Mr.T.S.Ananthu Hon.Secretary has written a detailed article on Solar Power, which you may find in the following link.

It depends on local conditions. You have to do a cost-benefit analysis for your location. There is a fixed initial cost (equipment, construction, permit etc), Then there is running cost (maintenance, cleaning etc). The running cost of solar panels are very minimal, generally there is very little maintenance. If you want to store the electricity, you will need array of battery etc. There will be days when it is overcast and no sun, and so no power, of course you can not use solar power at night. Please do more research before jumping in to solar power.
There was an article in the hindu about a solar powered home in chennai in egmore area. The article is recent, less than 30 days old. I remember, the installation costs about Rs 2 lakh, but the govt gives a subsidy of 85,000, for a capacity of 1 kilowatt, sufficient for normal needs.
to encourage Delhi Govt. offered solar power with equipment and installation free of cost sometime back. I think maintenance will not be very costly. I tried to introduce in the Society where i live. in these days of power-cut, solar energy should be a welcome one. possibly, cheaper too.
My sister-in-law bought a house in a village near Madurai and installed solar power, to replace electricity.

After about two years, it has become totally useless. Please get more feed backs before investing a huge

amount of money. In Bangalore, my friend has solar power for hot water and it works well!
When generally speaking that I wanted to use electricity produced by solar energy for my home, you would also think that Everything that uses electricity, will be using Solar power electricity. I want everything in my house run on solar power in simple words. You will need Solar Grid-Tie, Solar Panels, Inverter and Battery/charger.

I will put all in basic simple way without depth in word so you can get the basic idea of what is for what. Solar Panels are what absorbs Sun heat, and inverter is what transforms solar energy in to electricity and transfers it to battery (one like cars have) or charger. And other basic accessories like controller etc is there to add in to cost, along with cost of installation.

Solar Panels are important factor. Average 1 Square Foot of Solar Panel produces 10.6 Watts. Average cost for 1 Square Foot Solar Panel is around Rs. 4,500 plus. You can lit a light of a room for that much. So, for basic appliances like TV, Computer, Fridge etc, it will need much more. So, for that you will have to sacrifice half of your terrace, will need large solar grid-tie, and 60-70 panels (if your terrace is big enough!). Than cost of Installation which is not so cheap either. Your home will need to be in area where sun comes directly on solar panel, and of course if you are in crowded area, make sure neighbor’s kids doesn’t jump on solar panels for sun bathing, so somewhat safety issue. Now, these many solar panels, will it still be enough? how long will charging last? Well, it will last almost a day in general thinking. It has to be charged constantly. As I said, it will produce 10.6 Watts in 1 square foot panel, you can see your electricity bill and compare how many watts your house uses in a month, and do all math. You will know average how many panels you will need.

So, cost for whole home system will run around Rs. 12,000,00 plus including all accessories and Installation. Please note that prices I am writing are what I gathered from information I found, and may be more or less depending on company that’s selling. But this is what’s average cost is around. Now, spending this amount, you still probably will need to be dependent on regular electricity as solar power may still not be enough!

Now, I understand that why companies who sell Solar Cooker, Solar Heater – just this kind of small appliances, doesn’t really offer total 100% solar system for city house. Because its just too costly, It will take years for this investment to break in even! Idea of Solar Energy is to cut down on Bill of regular electricity, by using this small solar powered appliances. Solar energy is good for home which are in small villages or outside area where government doesn’t offer electricity and where they just need it to light a few bulbs. It would be worth for that. But for powering up everything in home, it doesn’t seem worth in my view.

You all compare your bills, and Index | Selco Solar India, a social enterprise, provides sustainable energy solutions, and services to under-served households and businesses. is one of the company that I found offers solar system in India. You can get more information and response in details about setting up from them.
