Maybe of interest: Building solar panels handbook
You can build solar panels to internationally-patented plans, so long as you don't sell them commercially. Excess power (even in overcast countries, they ALWAYS generate excess) can be sold back to the power grid for profit.
As for situation, there are pros and cons to America:Pros:
Cheap real estate
Large choice of isolated regions
Secure from marauding paramilitary action (relatively....)
Very difficult for non-Americans to obtain visas without employment
Any transaction with a corrupt system is tacit support of the system
Economic benefits for the separatists will be minimal/non-existent when it comes to currency exchange (being as most would be Americans themselves).
Separatist movements falling increasingly out of favour within governmental thinking.
In the 1960's many ideologically separatist/collectivist sects were established in Afganistan by hippies. In the 1970's in India. The unintrusive government, dirt-cheap cost of living and the state support of "spiritual organisations" makes Asia a more realistic prospect.
