Australia is even cheaper, I paid around USD 0.6/W for my system (including subsidies, it's closer to USD 1.0/W excluding subsidies). Break-even will be in around 3-4 years. I noticed (by following the solar sub-reddit) that almost every single US install has either Enphase or Solaredge inverters (which happen to be on the pricier side). I am not sure if that's an indication for the lack of competition but surely this seems like an industry where disruption is possible?
