[math-fun] thermodynamic question

[This is a thermo question, not a climate troll.] California just passed energy efficiency requirements for computers. 1. If I have an inefficient computer that requires twice as much power to run a particular computation as another, "efficient" computer, then almost certainly my inefficient computer is "worse for the environment" than an efficient computer. 2. What if, on the other hand, I power my "inefficient" computer using solar power ? To avoid grid issues, I'll power my inefficient computer directly from a solar panel so that it isn't connected to the grid at all. The sunlight is going to be eventually converted to heat whether my computer is there or not; so what difference does it make?
