Mandating the expense of solar on all new construction is not economically beneficial for all home buyers, and such mandates in general smack of handouts to cronies masquerading as green initiatives.

Okay, so solar companies benefit, but the home owners save for decades. Our panels do well when even the UK. Installing during build is cheaper, but the companies don't want any extra costs. They should insulate better too.
Obviously need decent export tariffs.
Some can't afford the up-front expense. While it is cheaper to build in solar from the start, that hurdle can be insurmountable, and prevent people on the margin from building at all.
Well the finance could be managed by offsetting the cost against earnings. This might only add a few percent to the purchase price anyway. Builders cut their costs and make the house more expensive to run.
Many countries already offered incentives to improve efficiency, but we need more take-up.
We need nuclear power for baseline load and other more responsive options for fluctuating demand.
