I talked to one installer here in RI, and gave me a quote of 1kw system for $4,300 installed.
I'm planning to get 4-5kw system on my house.
here are the products that he'll be using:
Modules- AU optronics aka BenQ 260 watt efficiency 16.1%. All black module
with high output under low light conditions
Inverters- Enphase M215 CEC weighted efficiency 96+%
Module PTC rating- 233.4 watts
Module warranty- 10 year workmanship, 10 year 90% output 25 year 80% output
Power tolerance- (-)0-+3%
Mounting- Quick mount integrated flashing, low profile mounts (about 4" off
roof for air circulation), Uni-Rac black anodized rail system with one inch
equal spacing between all modules for air circulation and best snow
remediation. Modules are 1.5" thick
so for a 5k system, it will be around $21,500
$21,500 - $5,375 (25% RI grant) = $16,125
$16,125 - $4,837.50 (30% fed tax credit) = $11,287.50 total in the end
What do you guys think of $4,300 installed for a 1k system?
what about the products that he'll be using?
The panels are fine, as are the Enphase M215 .
The $21500 price for the 5kw system seems high.
For reference, I just got a 2.8kw system installed in Northern California for $8500 before any incentives, 3 months ago.
That was using 12 Talesun 240W panels and 12 Enphase M190 inverters.
The CSI rebate I expect to receive will be small - only about $500. And the 30% federal tax credit on my 2012 taxes the total price less CSI rebate will be $2400.
So, after the incentives, the net installed system cost will be $5600. Ie. About $2/watt net installed.
A 5k system with the same materials would have had an even lower cost per watt.
Your RI state incentive is different and better than the CSI, but it sounds like your installer wants to take most of it for himself.
