Solar backup generator
I would like to install a solar system for the purposes of providing backup power on demand. Ideally, when the power is up I'd like to also feed back to the grid (this is allowed by my power company in my state), but I don't know how feasible this is. Does anyone have any recommendations for designs and vendors? I think I'm looking at around 2000W steady draw for my vital appliances, but I'll want an inverter (and a battery array) that can handle a 4000W max.
I don't think a wind turbine would be feasible due to the small acreage (4/5 acre) and amount of trees, but I do have access to a small stream that I might be able to do something with if the solar panels don't work out :-P
