For those who have modest needs, a solar can be arranged cheaply. As long as it is mostly low voltage.
I have seen old panels that have been removed from a home for upgrading, selling for upwards of $25 for a 200 watt panel. A couple of these, charging a couple of second hand old fashioned lead acid batteries, gives plenty of power for lighting and phone/laptop/power tool charging.
Maybe not luxury, but still affordable. Next step will be a small chest freezer to use as a fridge - run direct off another couple of panels via an old 240v inverter, it should chill down during the day and hold the cold overnight.
My friend had already accumulated most of the stuff but didn't know how to set it up. He is tickled pink just having electric lights for the first time in 4 years living in his shack.
