Well, there were no rebates involved in my system, and I thought my
installer's rates were reasonable for the materials he supplied and the
time and effort he put into it.

He also had no objection to my purchasing the panels and controller on my
own, as I could purchase them for significantly (to me) less than what he
could sell them to me for.

The total cost of the install, to me, for 1.98 STC kW, was $.58 per STC
watt. However, given the difference between my system and the OP's system
-- his being a new system being installed for a grid-connected application,
$ per STC watt would be reasonable, in my opinion.   And that's about what
he's paying, not considering any rebates.

"The PV module power ratings are for Standard Test Conditions (STC) of 1000
W/m2 solar irradiance and 25oC PV module temperature. "

http://en.wikipedia.org/wiki/Photovoltaic_module
"Module performance is generally rated under Standard Test Conditions (STC)
: irradiance of 1,000 W/m2, solar spectrum of AM 1.5 and module temperature
at 25oC."

STC, Standard Test Conditions. It is 1000 w/m^2, but real world is
closer to 800 w/m^2

Cheers
