A few points here.
One, I agree with Herk--unless you have a large SOLAR ARRAY and not just a panel or two, you're not producing enough electricity to make any type of sizeable dent in your electric use. If you unplug from the electric completely, as has been suggested, and try to run totally off your solar power, using your battery(ies) to run your inverter, you'll quickly see what we mean.
Two, I would not allow any CG to charge me for electric (over and above what they're charging me for a site) without having my own meter. But that was the deal you entered into, and now you're finding it unsatisfactory. There's no fair or equal way you can be charged for the power YOU'RE using. Which brings me to..
Three: $50/month is not a lot of clams for (what sounds like) unlimited electric usage. You haven't said if that amount varies or stays at $50, but if it does, it sounds like a bargain to me. Put your fridge and HWH on electric, buy an electric heater, and enjoy your $50 worth.
Or find a different CG and run the risk of being charged a lot more, as has also been pointed out. Or maybe getting lucky and finding one that charges less. In FL, good luck with that.
