I am ready to make a decision but I am concerned about the difference in Cost per Watt.
Why would one be so much lower than the other-is this a RED FLAG or just a great deal?
Very good reviews for both companies I am considering after getting 5 bids.
I use about 19.4k kWh per year with a $550.00 a month electric bill


Here are the two systems:

12.320 kW DC

44 LG 280S1C-PV panels
Inverters 1 SMA America SB3800-US-22 & 1 SMA America SB7000 TL-US-22
Cost before rebate $43,243.00
Cost per Watt $3.51

Second System

13000 kW DC

a. (50) Kyocera Solar:KD260GX-LFB modules on an Asphalt Roof
b. (1) SMA America: SB6000TL & (1) SMA America: SB3800TL (240V)
Cost before rebate $53,614.00
Cost per Watt 4.13

What do you think?

Thanks appreciate your input
