I just ventured into solar this year and it's surpassed my expectations. I installed 300w of solar in combination with my two group 27 batteries. I have a truck camper and our power needs are modest. We may watch a bit of tv in the evening and if it's cool the furnace runs but that's about it. We always cook outside, in fact I removed the microwave as I had no use for it. We never camp with services so we are always dependent on batteries and/or generator power.
I originally started with an inverter so that I could use my Keurig to make coffee in the morning and not have to use the generator. This allowed me to avoid generator hours and/or not have to wait for the generator to cool before we left for the day. I have a generator (Honda eu2000) which is reasonably quiet but I still don't like listening to it.
The next logical step seemed to be to install some solar panels to charge the batteries up through the day. I carried the generator around all season but never started it even once so I am now considering selling it. I still keep it for emergency use if we had to run the a/c to cool off our dog but our fan does a pretty good job. I'm sure a/c would be much more required down south.
