With 2 reactors and 2 aneutronic reactors, you can produce up to 40GW. That's equivalent to around 167 000 of bob's Large Solar Panel 3s, and the area needed for a 40GW fusion reactor is much smaller than you'd need for 167 000 solar panels.
And regarding antimatter: a single power plant can produce 1.5TW, which is equivalent to 6.25 millions of Large Solar Panel 3s.
I think the recipes are pretty reasonable.
