Wait, so those were not US residential cost figures you quoted? Because I don't see how they'd allow Chinese imports for only residential installation.


Those were also US, yes. I don't know why they were so much cheaper. Possibilities include:

- Maybe the SEIA is wrong.

- Maybe utility-scale projects sign contracts to buy PV modules further in advance. The prices were falling rapidly.

- Maybe residential installers were buying low-cost panels with lower efficiency or with no warranty.
