My roof size is going to tell me how much solar power I will need haha...
I can mount two 120WATT Panels in the front part of the roof on each side of my fantastic roof fan. Then I can maybe get a 240WATT solar panel across the rear part of the roof. That is going to give me around 480 WATTS of solar panels to use.
I don't know how others plan to use their solar panels but for me they will be used to supplement my generator run times to re-charge my battery from their 50% to 90% charge state before I lose the high the high sun each day.
My generator will run for about an hour to get my 50 AMPS PLUS initial charge current when the batteries first get hit with the 14.4VDC charge voltage. After that the DC charge demand tapers back to around 8 AMPS or so which means I can shut down the the generator and just allow the 20AMPS of DC charge from my solar panels to run until the high sun goes away in the rest of the day.
My WATTS being used will be determined on how many batteries I have in my setup...
Been living quite well using just 255Ahs of battery capacity for my one day/night run but want to increase that soon to two banks of 300AH's from each bank with one on my trailer and the second bank in the truck bed...
We usually camp at places that all have generator run time restrictions in place so going solar is really going to help out in that respect...
My DC Power demand will be restricted to what I can use coming from my battery banks... Using the generator is my first priority followed up by what I can produce from the solar panels. My absolute priority is start each evening with at least a 90% charge state on my batteries if I want to make it through the one day/night running the things we want to be running...
Pretty simple for me figuring out what my solar needs will be haha... Two panels in the front and a bigger panel in the rear...
