Solar and batteries get you through the entire day right here on Earth, plus you can shit in a toilet when you need to go on site to fix or upgrade something, not in a little tube. Plus you can probably just drive there instead of needing 15,000 feet/sec delta-v to get to orbit. And you can breathe. Surely the cost of batteries and panels do not exceed the costs and logistical pain-in-the-dick going into orbit will impose.
