Witch kind of solar panel is better, that with tubes or the other one?
Question:
the one with tubes, probably
Here is where you need to look http://www.builditsolar.com
They have all the information you need to decide on what system is best, where to put it and how to build it. I've been building my own solar projects for about a year and they have loads of information. You can build one for a fraction of what it will cost to buy one.
You may want to pick up an issue of Home Power magazine or Mother Earth. Both have ads for companies that sell ready to install systems.
Good luck. Enjoy the free heat!
