Unless they can lower the payload cost significantly it won’t be economically feasible.

I ran the scenario through DeepSeek and got the following results:

In order to launch a PV array into GEO with the same power output as the Three Gorges Dam would require:
60 launches of the Long March 9 Rocket
$13.5 billion of cost vs the cost of $29 billion to build the Three Gorges Dam

A very expensive project to be sure, but totally infeasible? Give it another 20 years and maybe possible.

I think it is better to go with a railgun based solution to launch most of the mass.
