Yes but the solar farm do not supply 550mw. That is their max (read theoretical capacity).
Whats the average slippage with solar due to say heat. Even on a perfect day, most solar panels will loos 10 to 15% of their capacity due to heat roll off. So your 550Mw farm is 467mw at max capcity. It doesn't churn out 550Mw hour after hour.
Per TWH of energy produced Nuclear is by FAR the cheapest & safest form of power the planet has.
