Is there a way to compare input and output energy of solar fusion to the input and output energy of man made fusion?

The Livermore fusion experiment was said to be 2 megajoules of energy in and 3 megajoules of energy out. However upon closer inspection the facility used 300 megajoules of energy. So man made uses 300 ...
