Also when using this system this would translate into an additional of about 150 amp hours on a bank of 12 marine deep cycle 12V batteries. Whereas adding an extra panel to a stationary array would only give an increase of around 15-20% and an additional 105 amp hours.
The reasons why I need to build this are all, because I want to.
It is relatively easy to charge a battery back to about 80% but the last 20% will take 8 hours or so at a relatively low current flow - large solar panels are no help at that stage.
Yes, I would have to agree with you on the wind turbines, at least traditional wind turbines anyway. I believe that I have found a viable option in a frictionless (not friction-free) Mag-Lev vertical axis wind turbine. Depending on the design it can work on either AC or DC and in less than 3 mph winds. I'm studying the designs right now.
