12. Who Should Get A Solar Generator 
    So now that weve covered all the aspects of solar generators, its time to figure out if they make sense for YOU.
     
    Of course, that depends upon your situation and your survival plans.
     
    And since I cannot answer that question for you, Ill provide some general thoughts instead. To give you some general guidelines on when a solar generators purchase is good and when its not.
     
    If you consider a solar powered generator as an emergency back up and not a full replacement, then they are a good purchase.
     
    They are not a direct replacement for your homes power consumption. If thats what you were hoping for, youre mistaken.
     
    Heck, even a sizeable nonportable fuel based home generators struggle with such a task. And those cost tens of thousands of dollars.
     
    A reasonably priced portable backup generator system (solar or fuel) requires prioritization.
     
    Prioritization Questions:
    Do you want one to run a small refrigerator in a crisis? Great a solar generator may be able to do that, but that will be about all it can do.
     
    Do you want to run a CPAP machine and charge a few smartphones? Great, but then running a freezer as well wont be possible.
     
    Do you want a way to have some lights at night and be able to use your microwave several times a day? Perfect.
     
    So youll need to think about your energy needs in a holistic way. Youll have to prioritize.
     
    For example one of the best solar generators can provide up to 1,**0 continuous watts of power. That about enough energy to charge the following devices:
     
    cell phone
    tablet
    survival radio
    a few lights
    a small appliance or a critical medical device
    Obviously, this depends on the energy needs of all these devices when added together.
     
    Or maybe, just maybe, with proper power management, you could power your freezer INDEFINITELY.
     
    If you can do this, youll never have to worry about your food reserves going bad.
     
    But the point is a single solar generator cannot do it all.
     
    If you want to get it all, youll have to buy more solar generators. But that comes at a significant cost increase.
     
    One way to be strategic with your limited power is to invest in solar lighting. That way, you wont lose any of your solar generators power to light. Solar lanterns have built-in solar panels and use LED lighting technology. Now, your emergency lighting needs are met by a separate self-sustaining solar device.
     
    Heres a post about solar lanterns if that sounds interesting to you.
     
    So the bottom line is this:
     
    You must fully understand what a solar powered generator can and cannot due. Thats how you make it a wise survival investment.
