Model S Owner here. Looking for advice/tips.
I have two offices that I am thinking about putting solar on. I have some money sitting in a CD that is obviously earning nothing, so I thought why not use that to invest in something with a guaranteed rate of return.
Both offices have flat metal roofs. Main office is a bigger building. Average monthly kwh usage is 1,000 kwh. Average monthly bill is $200-$210.
I emailed 4 solar companies for quotes, but only one responded. Here is his quote for my main office only, I haven't requested quotes for my branch office yet. He gave me two options:
System Details:
System Size STC Rating 8.55 kw

Average AC Monthly Solar Production 911 kwh
Your Average Electrical Consumption 1,100 kwh
Energy offset in % 82% coverage
Solar System to be mounted on: Roof Mount System
30 Solarworld 285w American made Or LG 25 year warranty
Option #1
SolarEdge & 30 DC optimizers
Gross System Investment $ 25,505.78

Other option:

So I guess my questions are:
- Do these quotes look accurate?
- No idea if the 2nd quote is "better" than the first due to the added costs? Just the warranty?
- Should I go ahead and sign up now and get on the waitlist for 2016 funds, or do I risk them being exhaused? Or should I wait until 2017?
- Should I keep calling until I get a 2nd quote?
- Or should I just wait until the Tesla/Solar City merger happens and see what they have to offer? Right now SolarCity doesn't offer anything in my zipcode.
