Damn, solar panels are expensive in the USA... In Australia a 6.6kw system with 5kw inverter runs about 3500-4500AUD installed and grid connected. The rebates

  "In Australia a 6.6kw system with 5kw inverter runs about 3500-4500AUD installed and grid connected." *after subsidies.

  The price has gone up of late, you are probably looking 4000-5500 depending on inverter quality (that's based on 2023 STCs) But that said, Western Power's inflexible blanket ban on any feed-in above 5kW (single phase) has had a wonderful side benefit of enabling solar companies to be ultra competitive with the 6.6/5 kW system installs because basically everybody wants the same equipment, allowing much greater standardisation. Electricity is still dirt cheap in WA (30c/kWh) but that will soon change. Interestingly, solar has penetrated so far in WA that there's almost no value to the grid operator of putting more daytime solar onto the grid.

    Fair point, I was going off 2022 prices. Yeah it makes sense that a limitation like that forces competition, along with cheaper import costs from China I imagine not hurting. 30c/kWh is not really cheap by most countries standards, especially when you really need aircon during summer and from this year can't build a new home with gas heating or cooking in WA. Going to be an interesting few years I think as grids start to move away from coal base loads en-mass
