Solar panels definitely have a place in RV living, however there is a reasonable amount of planning that should be done prior to buying anything. The first thing that needs to be done is to understand what solar can and can't do and how to decide what you need and the cost. First you need to determine what you wish to accomplish. It could be simply keeping the battery charged in storage or running many of your appliances. Once you determine what you want to operate, you need to determine the current load ( amps) and how long they will operate ( ie 3hrs of lights). For any 120VAC household appliances you will need to multiply the current listed for the device by 10 to determine the 12VDC requirement and you will need an inverter. There are several good places where you can do some reading. Renogy.com has a good tutorial. Also remember that you do not have sun all day and you may have several cloudy days so any energy generated will need to be stored in expensive heavy batteries.
