Most of the northern states don't have much sunlight and have cheap enough power to make it not worth it.
A common misconception. Even in northern Sweden, which is above the arctic circle, you can still generate ~80% of the energy that Southern Europe generates.

Based on the Australian experience, the next wave of price declines for residential solar will indeed come from balance-of-system cost declines, increased installation efficiency and lower profits. Current costs in Australia are about A$ 1.70 /pk-W (~US$1.35), pre-subsidies, split roughly into 35% modules, 10% inverter, 10% mounting system, 10% other hardware (cabling, switchboard etc), 10% installation and 25% "vend…

It has sunlight almost all year round, it has a pretty progressive government, and a leading tech sector. With house prices being so high, so the cost of solar panels would be relatively lower too.

This is fascinating if true. Do you gave any sources, I'd be really interested in reading more on the matter.

Here in SoCal, I have to fight off door to door solar salesman at least once per month. It's really annoying.
For what it is worth I do to. It is amusing to get to tell them I already have solar at which point they look up and then walk away. But think about it... What kind of margin pays to have someone walk door to door? That is the kind of waste that the system has not yet rung out and why residential costs don't seem to be going down as much as they should. As long as all of the installers don't drive their costs down th…

Inflation-adjusted residential costs according to nrel.gov are shown in the chart on page vi of https://www.nrel.gov/docs/fy17osti/68925.pdf The raw costs, not adjusted for inflation: Q1 2014: $4.52/W total for $1.03/W modules [0] Q1 2015: $3.09/Wdc total for $0.70/Wdc modules [1] Q1 2016: $2.93/Wdc total for $0.63/Wdc modules [2] Q1 2017: $2.80/Wdc total for $0.35/Wdc modules [3] Conclusion: Even if the modules cost…

We also had the renewable energy credits scheme which made the price float about a bit since they were a traded commodity and the installer would take them off you for a price reduction proportional to their market value (if you elected to not instead keep them for yourself and pay 'full' price, but then have to sell them yourself too).
Basically what I'm saying is that there were multiple levers causing the price to float around a lot over the last 5-8 years and it's not strictly just because gradually supply/competition grew.

Most of the energy comes from ambient light, direct light is best of course but not strictly needed
