Yeah, only one side up on this mission. Next mission has another one going up. They are also installing the SARJ, which will allow the new arrays to rotate during orbit to grab as much sunlight as possible. Once these two new arrays and trusses go up, they will remove some of the existing panels in order to install another set of two trusses with panels.
ISS is gonna be one big object in the sky in a few years.
And still, even if the panels catch the sun like that old telephone satellite system, what's it's name, it still won't be visible from Fairbanks.
