solar power question-very lite use...?

We Answered:

Hotplate and frige are gonna suck up the power. Better have a good battery bank charging all week. Radio and lights use nearly nothing. Basic upkeep is pretty much zero, except for maybe cleaning the dust and leaves off panels. If you or a friend is good with tools installation isn't too hard, just make sure you hook up the batteries correctly! Cost of panels depends on what kind you get and where you live.

Can solar car chargers work without having the key to the car turned to accessory?

We Answered:

If your cigarette lighter works when the key if off, then yes, the solar charger will work. That will confirm you have popwer to the lighter when the key is off, thus the necessary connection to the battery.

Wind Energy FAQ
What do I need to know to purchase a residential wind turbine?
Will my utility allow me to hook up a wind generator?

Federal regulations (specifically, the Public Utility Regulatory Policies Act of 1978, or PURPA) require utilities to connect with and purchase power from small (less than 80 MW) wind energy systems. A wind turbine manufacturer should be able to help arrange the required utility company approvals.

See State-by-State small wind information http://www.awea.org/smallwind for lists of interconnection requirements for many U.S. states.
