Yesterday my 200 watt solar panel I have hanging on the ladder rack waiting for installation parts put out 850 watts

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.
