Breaking Down the Costs of a System

[entgegnen]

As I finalize my project, I have started to think about the component costs of the system (the panel, the inverters, the labor, the mounting hardware,so on and so forth). While I frequently see folks discuss installed systems in terms of pre/post incentive $$/kWh... and I have also seen folks discuss specific panels in terms of $$/kWh (pre-freight)... I have not really noticed discussion on either labor, inverters, or hardware.

I thought I would just throw it out there to see what folks think an appropriate range would be for:

Labor $$/kWh
Mounting Hardware $$/kWh
Optimizers/Microinverters/Etc. $$/kWh

I do realize that conditions may vary greatly (especially for labor) based on geographic region and site criteria.
For my specific situation, I have a relatively new 2-story with a Terra Cota roof, in SoCal.

Thanks for any thoughts on these. I am getting close to jumping in to solar.

I think what you would find is that a typical DIY system (free labor) will cost $2 / W +/- maybe $0.50. Labor could be another 0.5 to 1.

if you have a real Terra Cota roof then expect costs to be very high. much more likely you have a cement S tile roof. which is just a bit higher for tile hooks

You are probably correct - "S" tile roof... just that burnt orange/reddish color - just so it has a terra cota "look"

Have you considered a free-standing array, instead of roof mounted ?

so something like this should work:

followed by some rails like ironridge XR100 : http://www.ironridge.com/pitched-roof-mounting/features

Not really a good option for me based on yard size, shadowing, etc. In my situation, I am ok with the roof labor cost just to keep as much yard as possible. Now if I had a ranch.... or a farm....
