1. Yes, we are getting to the point where solar roof are cheap

The most recent technology have solar panels replacing tiles. The difference in price is now marginal between replacing a roof with tiles or solar panels that can also be used as roof tiles.

This is more important then most people think. Old slate tiles could last over 100 years; but since the 1960s fiberglass has become the title of choice for they tend to be half the cost of slate. The downside of fiberglass is a life expectancy of just 20 years (they often last longer but no where near skate).

Thus as more and more roofs have to be replaced, solar panels are looking more and more the more cost effective choice.
