Hi jp,
Be happy. If you are happy, we are happy.
It is 100% RE related if the user wants to be off grid with RE,
Or has no grid at all.
Given a budget and other limits, sometimes it is better to think outside the "high efficiency box",
As you noticed when choosing a ceiling fan motor.
As I noticed when trying to make a solar chair charger on a fixed budget, here,
http://ghurd.info/wheelchair.html
It was a LONG time ago. Still running fine.
The only major part of making it work within the limitations was using a different battery charger, after realising the factory supplied charger was total crap.
The 600WH more a day seems a bit high. Wondering if that is due to inefficiencies somewhere.
G-
