Good thing I've found this thread. I've been thinking to try to install this electric heater https://houseweather.org/best-electric-water-heater/#product3 So I guess 12kW will use my battery quite fast :D
How much do these panels weigh? Are there any calculations if they are worth it on vehicles? They probably are if you camp much more than travel, but I'm not. My concern is gas consumption, trying to reduce it as much as possible.
