something in the wind, page-31

People who think we will all get off the grid are taking something or smoking something. There will be a few but unless you have close to 100sqm of flat roof facing roughly NW and a stack of batteries to get you through a weeks cloudy weather not to mention about $70k to fund it it's still in lala land.

Most houses have hip and valley construction so the number of panels that can be installed is limited. Check that with Google Earth to see how to install the minimum required 15kw system which is equiv to 60 x 250W panels measuring 1m x 1.6m..

IMO, the real future is in farms both wind and solar and that is where the flow batteries have a chance.

Not saying that a battery cannot be used for load shifting at home. Energy is gathered during the day but is mainly used in the evening so a way to store it for later use makes sense.
