Well, somebody had to post it. As if any of us could duplicate this, in its entirety.

Designed for a 15-year service life, the solar arrays have been operating continuously since the first pair was deployed in December 2000, with additional array pairs delivered in September 2006, June 2007, and March 2009. The first pair of solar arrays has now provided continuous electrical power to the station for more than 20 years as more modules were added and dozens of crews tackled thousands of scientific experiments and continued operations through hundreds of spacewalks, cargo missions, and more.



Though they are functioning well, the current solar arrays are showing signs of degradation, as expected. To ensure a sufficient power supply is maintained for NASA’s exploration technology demonstrations for Artemis and beyond as well as utilization and commercialization, NASA will be augmenting six of the eight existing power channels of the space station with new solar arrays. Boeing, NASA’s prime contractor for space station operations, its subsidiary Spectrolab, and major supplier Deployable Space Systems (DSS) will provide the new arrays. The combination of the eight original, larger arrays, and the smaller, more efficient new arrays will restore the power generation of each augmented array to approximately the amount generated when the original arrays were first installed, providing a 20% to 30% increase in power for space station research and operations.




The new solar arrays will be a larger version of the Roll-Out Solar Array (ROSA) technology that successfully demonstrated the mechanical capabilities of solar array deployment during its test on the space station in June 2017.
 
Bad earth connection though
floating ground is fine when you don't have anything else which you could accidental touch.

So just don't try fishing for other satellites or space stations when you are up there :)
 
Was poking around the NASA site and found this too, thought it was cool.

I've wrote a research paper about solar applications on Mars. Heavy things are very very very expensive to get to space.

So anything you get accelerated to escape velocity - should be light - and last very long. The price of the item you shoot up, is almost trivial, compared with the fuel cost.

Good solar panels and better batteries should make space faring a lot cheaper.
