Solar hardware is so affordable now that it's booming even in poorer countries. The most remarkable recent example is Pakistan, which has seen explosive growth of rooftop solar power, most of it receiving no government subsidies:

Pakistan has imported almost 45 gigawatts worth of solar panels over the last five or six years, which is equal to the total capacity of its electricity grid. Almost 34 gigawatts have come in only in the last couple of years.

It’s a very bottom-up revolution. This is not government deciding this is the route to take. And it’s not being driven by climate concerns, it’s all about the economics. Renewables are out-competing the traditional sources of energy.

Right, so that implies there's no need for homeowner subsidies in wealthy, developed countries.

Even in Gaza Strip you'll see sometimes solar panels next to the refugee camps, and broken ones on top of the ruins.

Yes it's awesome to see solar adoption without subsidies. Wonderful technology. Decentralized energy production is powerful.
