Even better if you can use it to power a humanoid robot for a real world plant golem.

fun fact: chloroplasts generate an electric potential across the cell membrane during photosynthesis. essentially, they have membrane proteins in their chloroplast membranes that push electrons from one side of the membrane to the other side whenever a photon hits the protein. It's essentially a natural photovoltaic cell.

That electric potential is then used to create ATP in nature, while we just directly extract the electrical power through cables.

Just that "power plant" I think most people associate with large enclosed facilities that house power generating equipment, which doesn't quite describe wind and solar farms. Hence that most people refer to them as "farms".
