1. I hear the dual pane windows have separation issues and need to be replaced often, also what does it add to insulation value, wondering if its worth the extra 2k and what it will cost down the road.
2. Can a simple solar system keep the residential fridge working or should we just go with the RV fridge as we will be boondocking some
Hi The_Boys,
Our dual pane windows are 7 years old. I have heard of one or two cases where one or two older windows fogged, but the idea that they have to be replaced often is pure fiction.
They don't add much insulation value because they're different from residential dual pane - no inert gas between the panes. But they do help with noise, and in cold weather they significantly reduce condensation and icing on the inside. Heat transfer in both direction through single pane windows can be huge, and dual panes slow it a bit.
If you install solar to keep the batteries charged, you can certainly keep the residential refrigerator running, but you'll have to look at all the loads you want to run and plan a system that delivers enough power.
