Yes transmission is important. Also it's unlikely the optimum will be "only technology X" wind and solar and hydro are not correlated 100% so having all will help. For PV on homes just look at Australia: https://cleantechnica.com/2023/02/28/nearly-1-in-3-homes-in-australia-covered-in-solar-panels/ https://cleantechnica.com/2023/02/28/nearly-1-in-3-homes-in-... In my coutnry solar is now mandated for parking lots: https://www.pv-magazine.com/2022/12/12/france-introduces-requirement-for-pv-in-parking-lots/ https://www.pv-magazine.com/2022/12/12/france-introduces-req... Home and parking take zero additional land, no transmission needed. In my town the biggest supermarket is currently covering its parking lot with solar, my estimate is that it will be 2 MW.
