The solar panel conversion of sunlight to usable energy to around 20%, with a theoretical max of 30%. So it's better than that.

That can't be true. The current record for non-concentrating cells is 39.5% efficiency using triple junction cells [1]
Concentrating cells are at 47.6% [2]

It's only true for a single junction. https://en.wikipedia.org/wiki/Shockley%E2%80%93Queisser_limi...
Multi-junction cells beat that limit, but they're still horribly expensive to manufacture which confines them to niche uses like spacecraft.
