The solar panels on RV's aren't meant to drive AC appliances like your AC and microwave etc. They are meant to keep your batteries charged to run your 12V systems (lights, controls, inverter for fridge..). Solar panels are great to have because without shore power or the gen set to charge your batteries, there is no way to keep them topped off.
You may want to try and better understand your RV's electrical systems. Specifically 12V vs 120. There are a lot of things that run on a coach that are 12V only. Lights, controls, water pump etc. The 120 items like your AC and microwave require being plugged in to shore power, or in the absence of shore power - that is why you have an onboard power plant - your genset. We used to run our AC while going down the road - for example or use the microwave when stopping for lunch. These things don't run on batteries.
