Looks like I took their estimated usage. Should be 10,460 production (or is that not what you were referring to)? -- nm

The others are just taking the kW rating and assuming 1 hour of full production a day (a good ballpark - I get 1.14 over the full year). -- nm - Reagen May 11, 06:55 14
- The certasun guy said my "sun rating" or whatever was like a 92 and that anything over 70 was good. -- nm - oblique May 11, 06:57 13

    - not offhand but here is a pic -- (pic) - oblique May 11, 07:11 [Attachment] 7
      - Can't calculate without a reference but it looks shallow. You'll probably get "better" production in summer (edit: I'm dumb) -- (edited) - Reagen May 11, 07:17 6
        
        Our usage estimates are non-existant so I'm guessing left and right about what we will use. The 10kWh option seems by far the most attractive both - oblique May 11, 07:20 5
        
        I think they're giving a rosy estimate on production. -- nm - Reagen May 11, 07:26 4
        
        Well, I will say, they are guaranteeing 228,401 over 25 years so 9,136 kWh. Yes, less than the 10k quoted but still... -- nm - oblique May 11, 07:33 3
        
        As in they pay you if you don't hit that? - Reagen May 11, 07:40 2
        
        Yes. 12.4c/kWh for shortfall. I mean, who is to say that any of these companies will be around 25 years from now -- nm - oblique May 11, 07:47 1
        
        A kWh might cost a lot more than that in 25 years. -- nm - Reagen May 11, 07:52
  - you should get a t-shirt that say 'My sun rating is a 92' -- nm - decline May 11, 07:00 1
    - Suns out. Guns out. -- nm - oblique May 11, 07:00
