Hope that stuff helps, if you’re looking for off-grid energy with more watts/BTUs per dollar. I’ve studied and worked at it for a few years.
Thank you! WIll add to my reading lists.
One simple thing for refrigeration - get a couple of two by 10s and lay the fridge down on them, like a chest freezer. You use far less power to keep the fridge cold, since all the cold air doesn’t spill out when you open the door.
It’s why supermarket chiller cabinets are usually horizontal. In THEORY, by doing that and only opening the fridge twice a day you can run them off a 4X4 panel easily. In practice, you need a burst from a gennie every so often to keep the batteries up.
BTW, the smaller freezer should run from very little PV module and battery. ...don’t know how well any freezer would run in ocean swells, though (off-level?).
