I feel like it would be easier to just harvest it here on earth.

Those damn clouds make that hard sometimes. My solar production at home has been garbage for more than a week from overcast skies and rain.
That true, but you didn’t have to launch anything into space.
I wonder what total cost would be vs over-building solar
I wonder how much additional heat this would add to Earth.
If it’s in low earth orbit as described, it would mostly be intercepting sunlight that would hit the earth’s surface anyway (although she also says it could collect light 24 hours a day, which would imply a much higher orbit).
But solar panels only convert a fraction of the incident light into usable power—most of it is re-radiated as waste heat. In that respect an orbital array would heat the earth less than a surface array, whose waste heat is trapped by the atmosphere. (And either one would heat the earth less than burning fossil fuels.)
