Solar with a residental fridge

Glad you are going the solar way.. Just a few points to keep in mind. Fixed solar panels are only going to give you max power for roughly 3 hrs a day if they are facing south. Unless you have a tracker system on your RV or you are going to keep adjusting the modules better triple the amount of solar you think you are going to need. As for buying solar panels check Craigs list for them. When I come across modules I sell good used 250 to 350 watt panels for $100.00. I also get modules where the glass is shattered that I sell for $50 each. Reduction of output on these is only about 10%. You can add clear coat over them to keep the moisture out.
