8. The form factor of large, flat PV panels is great, but see #7, many roof planes can't accommodate any or enough panels to make it worth it. We need to be able to cover all roofs and walls with PV producing material.

I'm sure there's more but that's enough to start with.

So yes, parking cover PV. Efficient use of capital probably will require all utility scale solar possibilities to be exhausted before parking solar.
7. About 2/3 of USA rooftops are not usable for solar due to either shape or shading. Building codes need to require new construction to be optimized

insurance, office, warehouse, and the various software subscriptions needed.
6. I agree that parking lots and really all built surfaces should be PV electric producing surfaces. Who pays? The cost of parking lot canopy solar is 3x to 4x the price of utility scale solar due to scale and complexity.

inverter/battery for an 11 kW solar output system is $1.76/watt.
5. The USA cost of "balance of systems" components which are transfer switch, disconnects, racking, wire, connectors, conduit, panel optimizers etc is $1.00/watt.

None of this includes customer acquisition or operating overhead like

that AUS trade installers are paid more than U.S. trades. The total AUS installed cost is $0.50/watt. U.S. roof top installers are paid $0.50/watt, just for the rooftop, not including the "wall" or interconnection components.
3. The USA cost of panels alone is approx $0.75/watt.
4. The USA cost of

Enforcement of the codes is different in each AHJ.

The fire path requires a 36” path to access each roof plane. The access path can be on an adjacent plane which is often overlooked by designers who are often third parties, offshore, with no formal training or licensing doing the drawings for pennies on the dollar billed for the drawing.

I always wore Red Wing. Get them repaired and resoled over and over and over.

You didn’t know that the specific density of smuggled cocaine is less than ambient air when inverted and submerged under the half hull of an open boat? Freshman engineering stuff man. They were on the verge of getting airborne and opening fire with still stowed weapons.
