Hello, I am getting ready to pull the trigger on a new system for my RV and looking for a recommended quantity of solar panels (Mega 100 Watt Solar Panel Poly) needed to keep up with my system. I will be purchasing a MPP Solar - PIP – 1012LV-MS solar controller / inverter and (2) SOK 206ah batteries. Question is based off a 12v system utilizing between 10-15 kWh a day. Thanks for any suggestions you can provide.​

 
15kWh / 5 solar hours = 3000W solar panels.

Are you ready to install 30 tiny panels?

You should look for big cheap panels on Craigslist.
 
15kWh is about the same as 6 of your 12V 206Ah batteries so you definitely didn't mean 15kWh.
15Wh is about what you might use running a few LED lights for about 4 hours so you definitely didn't mean 15Wh.
1500Wh (or 1.5kWh) would be about right since that's 28% of your battery capacity.
