US homes are stick built. The roofs are not concrete, they are shingles. This is the single biggest bottleneck. On concrete, its super easy to add a simple steel frame, add panels and done.
Shingles have a shelf life of ~25 years. Most people buy old homes. And the roof is somewhere in the middle of its life. Its usually better to replace the roof and add solar at the same time.
The people who buy new homes have already maxed out their budget (people buy the biggest home they can afford, maxing out the downpayment) and they aren't thinking of adding solar rightaway.
2) Americans are pro fossil fuel (thanks to fossil fuel shills). Installers spend a third to half the money on door to door salesmen. This cost is absent in other countries.
3) US govts make solar unbelievably costly, by regulatory capture, tarriffs, banning panels from China. And they create perverse incentives of subsidies which make the installation costlier because it has to go through licensed installer to avail of the subsidy. The licensed installers always charge top dollar because its a captured market.
Virtually all roofs in the Netherlands aren't concrete but wood frames with ceramic tiles. The PV is just attached to the wooden frame, not the shingles or tiles.

You can just take off the PV when replacing a roof, costs a few hundred if you don't want to do it yourself. Trivial compared to the cost of a new roof and probably less than the savings in the meantime they're on the old roof.
