This is probably the cheapest way you can do it other then just setting the panels right on the roof! I think that the 4 inch screws may have costed more then the 2×4′s! After we get the whole system in and working I will try to make a video covering all our costs.
If you have not already watched the other videos in this series and would like to watch them in order. I have a playlist on my channel of all the videos of the solar project. Link to the playlist here: http://www.youtube.com/playlist?list=PLjzL2Xfa7hB1LLn6Ctmz1aNphWPed01Na
Thank you for watching!
