- sp332 7y agoThe energy is free, so efficiency is only important for comparison reasons. Is there something better we could be doing with that solar panel output? Solar panels themselves are maybe 22% efficient to begin with so this process cuts the efficiently to about 1/3. Personally, I'm impressed that it's even positive.
