That is very impressive, for such a system at just 1000 /kw , whereas the least quote for install I got was $2.35/W.
If I may ask. Could you post where you could source the necessary panels, inverters and other components and prices.
That would help wannabes like me to go for solar install diy.
I shopped around and bought most things from different online sellers, panels and inverter are new in box, but were discounted due to being what I call (last years models), The panels were 315w and they make slightly larger wattage one now, the inverter was made in Nov 2015 and the newer one is a little different, both from Ebay sellers. Iron Ridge racking was from Webosolar. I bought things as I found good deals on them, over the winter and stored everything until spring.
