We never plug in to shore power even at home except battery charging once or twice in winter. No generator. We camp only in Canada, usually fairly far north where air conditioning is not necessary. Some charging from the engine while driving. I tried a single 100 watt solar panel flat on the roof first to see what it could do. I was very pleasantly surprised that it fulfilled all our electricity needs. Since installing the solar panel about 5 years ago I have never seen the batteries below 80% charge. Now we don’t worry about electricity at all - water is the limiting factor in our boondocking. We were just out for a full week in campsites without electricity with the battery monitor indicating 100% all the time. The freshwater tank and two jugs of drinking water just made the week. We use propane for the fridge and making tea or coffee on the stove.
