How to make a solar panel at home?

Yes we are having load shedding in our area, to tell that more appropriately, we get electricity for a few hours in a day!

I am curious, how to make a solar panel at home? is it possible in India? Is it cost effective? Any company supply materials at an affordable rate. We are planning to make solar panels in all our homes(a group of college students). Any help is much appreciated!
Good question which made me think. Same here in my location too, I believe this is the case for major part of our country. I never thought of doing it at home, basically if we can collect Sodium bicarbonate, we are half done. I found a few reference pages for making solar panel in a very cost efficient way:

A transparent CD case, Sodium bicarbonate or Table salt, wires along with assembling materials and soldering iron can be the basic materials you would require to start. Best of luck for your project!
