The US already has 121GW of solar installed the majority of that being large scale Grid solar. Which shows the transition is already happening at current prices.

A major part of that equation is there is a lot of land in the US available for under 2,000$/acre, however spending more is a tradeoff to reduce the need for longer distance power transmission etc.

PS: 10B for 100GW at 30% capacity factor for 20 years is 10,000,000,000$ / (100,000,000kW * 0.3 * 24h * 365 * 20) or 0.2c/kWh ignoring interest. So, I think you messed up your estimate somewhere if you think that’s uncompetitive.
