So here is the list of pieces I used to build my hydroponic system.
2- 2x4x12 pine lumber - $4.80 each
7- 2" PVC pipe 10' - $6.67 each
10- 2" 90 degree elbows - $1.06 each
3- 2" T's - $1.79 each
12- 6" Carriage bolts - $.47 each
1 - 1000 gph water pump- $51.00
10' - 3/8" clear plastic tubing - 7.00
Total = $135.36
Everything I bought at Home Depot with the exception of the pump. Which I was able to get at Aubuchon Hardware. So not bad considering if I can continuously grow year round then the savings to my grocery bill a month will pay for this in one week.
For the Solar Panel I used the following items.
1- 4x8 sheet of 15/32" plywood - $24.97 (this is enough for 2 panels)
1- 4/8 sheet of pegboard - $17.95 (again enough to build 2 panels)
2- 1"x2"x10' trim- $3.97
The solar cells I was able to purchase on Ebay for $105.00 for 120 cells.This also included tabbing wire, flux pen, solder, lead boxes, and bus wire. So each cell comes out to $.87 each. 48 to make a single panel comes out to $42.00.
Total = $92.86
Now I happened to have the plywood and pegboard from other projects hence why I said about 70 dollars for the panels originally.
Again I would be more then happy to help out building your own one of these projects, there are also a number of helpful instructions on the net like this one; http://www.mdpub.com/SolarPanel/index.html
