Paint only half the bottle black and aim clear side at sun for fastest heat up. Reflectix in c shape concentrates solar radiation.
I almost always have some 90 degree or hotter water. I think of it as additional energy storage.
When i use 12v heating pad. Heating shower bag via sunlight saves significant battery power.
The black south facing dashboard is awesome. But in cooler weather the dashboard can suck heat from the bag. I have a dash rug which slows the transfer of heat to and from bag.
In cooler weather if the bag is up against the cold glass. No bueno.
One can go bonkers maximizing harvesting the sun's heat for water.
But so nice to have, especially when no propane or electricity is required.
