I am soooooooooo tired of listening to off-grid owners whining that they "designed" their system with spreadsheets, graphs, charts, and astrophysics aids...
"It doesn't work with a ****!"
Get an amp hour meter installed FIRST FIRST FIRST
Then live in your rig and get the 1st stage perspective of how much energy you consume nightly.
Add batteries. Forget about the panels for now - they come last.
Once you have stabilized your lifestyle with knowing negative amp hour consumption
THEN
Add panels. 50% of your battery bank capacity is going to be no-touchee.
Solar panels as a charging aid alone need to be sized much larger than if you have a generator. Same thing for 3-4 day outings. Smaller. Serious boondocking on solar alone calls for lots of panels. So does camping when overcast or clouds deduct from the "harvest"
This is the SOLE WAY you are going to end up close to what you want with a minimum amount of money.
Spreadsheets my ass. They are only useful for solar farms where matching panels with inverters and transformers is critical. And yeah, I did a ton of residential, off-grid, and boondocking installations.
