With some quick-and-dirty visual estimates from the charts, I'm coming up with about .85kWh/day. Yeah, I know, but I looked at it twice. I went back and looked at some other time periods as a sanity check. And <1kWh/day is what we get. In the summer. Right now the RV is sitting in the drive with the panels uncovered, and the driveway is sloped and slightly angling the panels to that sad little January-in-Seattle sun. Yesterday the panels cranked out a massive 0.1kWh. That's right: enough to run a 100W light bulb for an hour.
Despite all that, it's enough to run the microwave a couple of times a day (which is really the only large draw the RV has), watch some TV, run the lights at night. And if the panels can't keep up, that's what the giant-ass 300ah lithium house battery is for.
What I'm seeing on this topic is a lot of folks that I can only assume have never spec'ed out and used a solar installation. Go throw some panels on the roof of your house and RV, and then we can talk about how "all we have to do" is put panels on a passenger car. Not one of the "all ya have to do" crowd has mentioned how efficient their solar installation is, how the math works. Nope, it assumes a spherical cow, yada, yada, yada, and the sun is always pointing at a direct 90 degree angle to the panel.
The 410W on our RV, for example, is good for recharging the house battery after running the microwave to make breakfast. If it's cloudy, you won't get to run the microwave for supper, but at least the lights can stay on.
