Solar Panel Size To Battery Bank Size
When you pro's talk, having solar panels sized to battery amp size, are you referring to total battery capacity or the 50% useable battery capacity? I am working on my Solar system, I have a total hou...

reed - The 50AMPS plus is coming from my on board Converter/charger unit run by the generator. When it tapers back after about an hour of charge running then generator then I will be able switch to the solar panels. I will only be getting just alittle over 20AMPS of DC CURRENT from the solar panels in high sun. I haven't added the panels yet but planning on putting two 120WATT Panels on the front on both sides of the Fantastic fan and then a 240WATT Panel across the rear of the roof between the Air Conditioner and the rear edge. That adds up to 460WATTS.
The 240WATT panel should be easy to move to the ground if needed. I may run into a weight problems adding these panels to roof and try to raise the electric roof when setting up. I may have to add the 240WATT PANEL after I raise the roof.
Some of the experts tell me I can almost make getting my batteries from 50% to 90% charge just using the solar panels for 5-6 hours of high sun. I'm glad I have the generator along me as I know that works every time rain or shine... During a typical day/night run I am pulling the usually 1-2AMPS parasitic loads an around 20AMPs load from 6PM to 11PM to run all the home entertainment, lights, and ham radio stuff. This drops my 255Ah battery bank down to around the 50% charge state by 8Am each morning.
All still in the planning stage here for solar - waiting for money to fall out of the sky hehe...
I've been camping off the power grid with my 255AH battery bank for 5-6 years now so know what to expect to keeping the batteries giving me great performance.
Adding solar panels will be a big help.
We also mostly camp off-road here on the East side of the US and have to live with all the generator run time rules everywhere. Adding solar panels should drop my daily generator run time down to around one hour hopefully.
