Fortunately solar panel production capacity just keeps accelerating. Capacity for 300GW/year right now, and factories underway to increase that to 900GW a year well before the end of the decade.

May not all run at full capacity, but chances are even more gets built. We currently have just over 1 TW of total solar installed worldwide, and I wouldn't be surprised if we are installing 1 TW/year by a decade from now.
