(Corollary: you need to provide sun-equivalent levels of energy to a region before it's worth using your source instead of solar panels. Also, since it's so "diffuse" you still need solar-panel-sized collectors. Or actual solar panels, depending on what you're sending. And either way, the Earth is basically hotter by a day's worth of temperature change.)
Non-ionizing water-transparent radio frequencies of laser say "hello". You set them up so literally only a rectenna can receive energy from them: the laser will just pass through everything else harmlessly -- and even if it didn't, it would be diffuse enough (thanks to the square cube rule for aperture diameter and energy density) that you'd have to stand still underneath it for hours to get a sunburn. Then you build your building-sized rectenna (receiving antenna) station wherever the power needs to be delivered and allow that location to enjoy 24/7 2x peak solar output equivalent.
Even the absolute best places for solar power can't provide even a quarter of that kind of yield, mind you: day/night cycles, angle of the sun reduces peak yield to only a fraction of the day, inclement weather reduces yields further, and so on and so on. By using water-transparent light frequencies you not only don't warm up the environment, you're harmless to bystander animals ... and you can ignore clouds and storms almost completely in terms of getting power to the receiver. By using a beamsat and reflectors you can target anywhere on the planet at all times as well -- meaning that you never drop power to the receiver.
And since you're not doing broad spectrum of light, you have no UV output to cause cancer or the like.
This is a real-world thing mind you: this is the sort of thing that people in the L5 Society have been advocating for literally
decades.
I get the whole "comic book physics" thing, and "comic book villains and heroes setting", but that doesn't obviate real world stuff.
...That might actually work. Just flat out claim you're a (benevolent?) villain, but at least your stuff has useful side effects, compared to that other guy's death rays - his contain gluten!
"It has been my observation that heroes prevent villains from doing harm, but otherwise preserve the status quo. To disrupt society, to impose your will upon the world; these are the acts of a villain. Very well then, I shall be a Villain of Justice. I shall bend my labors and wealth towards building a better future for all thinking beings; one that enshrines as sacred the inherent dignity of all the peoples of the world and uplifts all those who choose to walk this path with me. Thus shall I rule the hearts of the world and lay wrecked beneath my ever so stylish heels the status quo."
Like I said. Lean into it.
