This makes no sense. A 200 watt solar panel is rated to produce 200 watts at the maximum; i.e., full sun and directly overhead. Efficiency also drops off at higher temperatures such as on the roof of an RV. Of course roof mounted panels are going to be at a severe angle away from the sun for most of the day, depending on the length of daylight and latitude.
The poster is confusing "watts" with "watt-hours".
Getting 4-5 times the rated watts in watt-hours is pretty typical.
Also, an air/conditioner is a heat pump, so converting wattage directly into BTU is misleading. It's using power to capture existing BTU inside and push them outside.
Think of it like lifting a 4000lb car vs pushing a 4000lb car. I can push a 4000lb car on flat pavement but no chance I'm going to lift it.
