Q&A: Are solar power panel arrays and a wind turbine generator practical for residential use?

Question by sunrayman123: Are solar power panel arrays and a wind turbine generator practical for residential use?
I ran into a “pitch ad” for a way to not only get “off the grid” at my residence, but actually have the electric company require sending me a small check for adding electricity to the grid. Is this stuff feasible or fantasy? I do have tools and could install the panels on my garage roof in chicago,IL.

where can i find a residential wind turbine with a collapsible or folding tower?

by Mr. T in DC

Question by pgiesen55: where can i find a residential wind turbine with a collapsible or folding tower?
i would want a taller tower (the higher you are the more wind) but i want to be able to service the blades and anything else without climbing the tower or renting a lift

Best answer:

Answer by billrussell42Never heard of such a tower. You probably would have to have it specially designed and it would cost a lot, so it probably is cheaper to go with a standard tower and renting a crane when needed.

Q&A: Homemade Residential Wind Turbine Project?

Question by J S: Homemade Residential Wind Turbine Project?
I have a photo journal of my residential wind turbine project at http://www.mindchallenger.com/wind

Unfortunately, there are a lot of trees in my area and cutting a few won’t solve the problem. However, I get some good wind in the winter.
