Latest Cost per Watt to Install Solar

I just found this website today on the latest CA Solar PV pricing http://gosolar.la/contractors/offers
  
This is from CA where they receive the containers of solar products which arrive there from China, Japan, Korea, etc. The cost for these products is the same between the Midwest and CA except I have higher shipping costs to get these
products to the Midwest.  Also, none of those offers use the safer and more expensive micro inverters.
 
I also received info today about this website http://www.ilsr.org/solar-costs-grid-prices-collision/ which is saying that the solar cost is $4.00 per watt and that at that price it might be too low.
 
I knew I was competitive in my pricing but didn't know by how much, till now.  
 
Also, I heard that module prices are slowly going up due to the tariff the US Gov put on Chinese modules. It now gives all the solar module companies a reason to raise prices.
