Now I have to learn about charge controllers and inverters. Any advice on sizing with the plan that I may double this in the future to also support a refrigerator?

Any feedback on Renogy panels? I've been using one to charge my Goal Zero Yeti and I have to say that their customer service is awesome. I had a 2 year old panel that I paid $200 for fail last week and they shipped me the new version for free and even refunded the difference from what I paid in 2015 since the price has come down. No hasltes at all and I was very surprised about the refund.
