I agree, but only because the exact same materials could be used to make a solar panel, and the two currently aren't even COMPARABLE in power generation.
The way it is now, you'll only get stable power generation in the post-game. During the 14 days the "advanced power generation" research tree is nothing but a big disappointment and you're better off just building two batteries and two biofuel generators and using that to hold your power supply up overnight.
