> We currently make around 1 TW of photovoltaic cells per year, globally.
Doubling every three years; at that rate it would take about 30 years for 1TW to become 1000TW. Whether on not the trend continues largely depends on demand, but as of right now humanity seems to have an insatiable demand for power.
We’re not going to use 100% of our solar panel manufacturing capacity to power space data centers, specifically because everyone else on the ground is so power-hungry. If we’re being generous, it could maybe top out at 1%, which adds another ~20 years to your timeline for a total of 50. I think it’s safe to say this part is bunk (along with everything else about this plan which is also bunk).
Plenty of space still, but we're running into other scaling issues now - power grids are at their limits. And on sunny days there's a lot more supply than demand, but that can be mitigated by adding more (battery) storage.
