if solar panels are at approximately 25% efficient on earth. the most benefit you could get is 4x. So you would need 4x the amount of solar panels if your project stayed on earth. the price to put it into orbit would have to compete against the price of solar panels for this to be economic. with a price per weight you would be able to estimate the scale of the project where this would be economic.
There’s a price per sqft of land versus price per kg to launch calculus that I’ll put together. Thank you.
