The numbers and conditions that favor one or the other change daily and from situation to situation. What is not changing is that it’s all trending in the direction of solar and away from generators.
I own both, have for years. I have a 5500 watt generator for emergency power at the sticks ’n’ bricks. I had a 2000 watt inverter generator for several years until it sprang internal fuel leaks and became both unusable and unrepairable on a camping trip. I have built 3 entire camping/home solar rigs and currently have one running a household refrigerator in an outbuilding and another for boondocking in the RV. The latter features a 400 watt solar panel and a 314 amp-hour Lithium Iron Phosphate (LiFePO4) battery, 2200 watt pure sine inverter, and 40 amp charge controller, which is enough power for everything except the AC for indefinite stays in the wild as long as we get a sunny day once a week or so.
My experience has been that on a cloudy/rainy day, you get about 1/10the the output from solar that you get on a sunny day, and that a sunny day with no shade, you will get 4-5 times as many watt-hours as you have watt panels, thus my 400 watt panel will produce 1600-2000 watt-hours on a good day. And that’s enough to light up all the lights, fridge and furnace control boards and fans, phone/laptop/tablet chargers, microwave uses I go through on a daily basis. Your mileage may vary, but the silence, lack of exhaust smell and carbon monoxide, oil changes, etc. work for me.
The price of components, panels, controllers, inverters, and batteries has come down over the last 5 years to where solar is cheaper in the long run by far. The only advantage left for generators is space/weight for high capacity uses, such as running AC.
Lights? LED lights in my TT take so little juice I don’t even factor in their consumption.

they count. In my old pull behind I put led boards in the old fixtures, they drew about 125mA but wen't the brightest, but good for the time, in my camper I cnaged the whole fixture and they are about 225mA/side so that about 1/4 of running an incadecent bulb. on its own ya its 1.4 of a amp, but now put two or three lights on plus the outside lights and you can add up to 2 to 5 AH pretty easy.
