A couple hundred watts of solar on the roof, a solar charger, a couple golf cart batteries and a small inverter is as close to free ac power that you will get in this life. After the initial investment all you will have is battery replacement costs every 3-5 years (depending on the quality batteries you choose and how well you keep them charged and watered). On the cheap side, you can get GC-2 batteries at Sams for about $85 ea. Trojans have the potential to last a little longer but will cost a little more too - so it's sort of a wash. I have a cheapo 400/800 watt inverter that I've had since 2007 and it still works great. While hardly essential, a reliable source of both 12v and 110 power, even in small amounts, is very useful for powering fans, lights, water pumps for showering, power tools, compressor, electronic equipment (I often run a 19" TV/DVD player & laptop, others might run a radio/stereo or CB radio), portable fridge, charging batteries, phone, etc.
I have a single group 27 battery and a small camping generator that I run for a few hours every couple days to keep it charged up when off-grid in my Aliner. A couple hundred watts of solar would virtually eliminate the need for the 1/2 gallon a day (on average) gas expense and the noise and maintenance requirements of the generator for battery charging. Of course my little 1,200/1,500 watt Triron generator can run my 5,000 btu air conditioner, where a solar/battery set-up can't, so I still can't ditch the generator for peak temperature needs, but I'll sure be able to run it much less and not cycle my battery as deeply, making it last longer too.
