Its cheap (its just silicium plates), we will have organic based systems in the future. You will be able to print it in the future.
Efficency is huge. We have so much unused roof space, its ridicoulous. parking spots, house roofs, commercial building roofs.
Why would you think its smart to send computers, which need cooling, up to use the energy over there? Do you know how hard it is to radiate heat away in space?
Rooftop solar is pointless. Roofs don't scale; roofs are not optimally placed; roofs are hard to reach; roofs are not engineered to support the load or hardware. Open cheap unobstructed ground near a grid with clear access are optimal. Roofs are exactly zero of those.
Efficincy is 50% at best - the daily occurrence of the terrestrial eclipse known as 'night'? Remember?
Any panel argument is the same in space. Don't know what that point was about.
Using energy near the generation point is optimal. The heat argument is good; it goes double for a planet that's already heating up and causing problems. Get that shit away from our ecosystems.
Any advantage of ground-based solar is eroding daily with advances in lift cost, land price rises, congestion in cities. It's only a matter of time and money.
And southern walls.
