Where can I find tutorials for building solar panels?
 

Ok so.. i am little bit interested in building solar panels on my own i was wondering where can i get those tutorials (video tutorials not books) and my 2nd question is, is it possible for someone to learn these things through this way?
Thanks in advance.. :)

Try this for starters...Earth For Energy - How To Build a Solar Panel Step-by-Step

Would it be cheaper to build it yourself?

That's a really cool link. Now all I need is like 10000 of those solar cells. Seriously I love this type of DIY. I'm thinking of ordering up some of those microcrystal cells.

here is one manual for building solar air heater. It can not produce electricity, but it has much more efficiency, and you can use it for home heating, and lower your bills.

Very interesting, I will be watching for your updates on this DIY!

I would do a thorough search on YouTube. Otherwise I would try a site called VideoJug

I'd like to know if its really worth the effort of making the panels myself. I want to make sure its effective too. I might be able to save up but how much energy can it provide?
