As long as you are willing to hire your own electrician or even install everything yourself the parts for grid tie solar are not expensive! Here are some pieces that can be used to build a system that should be well under $1 per watt if your racking isn’t very expensive.

 

For racking what I did was spec out the system at ironridge.com and then take the generated Bill Of Materials over to www.ressupply.com to purchase. the prices were half or less than MSRP and shipping was a flat $150.

 

Check out the parts list below for other pieces and suggestions on quantity for a very nice 6kw system.
