Solar Panels??

First, I look for one that fits on the top of the limited landscape of a Truck Camper's roof.

Don't go too large if you are going to tilt them, due to Wind, Snow Load and getting up on a small roof to work around them and not fall off the roof.

Do a Demand survey of what your needs are, to match the Solar/Batteries to your needs.

Lots of good Solar and Solar information from these fellow RV.net posters;

Hi,

Solar panels are a solid state device. I'd look for the best price per installed watt.

Here is a simple flow chart.

Budget-->Energy Audit-->Battery bank size-->number of watts-->PWM or MPPT.
A rule of thumb is between 60 and 150 watts of panels per 100 amp-hours of storage. The smaller the battery bank the high the wattage needed (per 100 amp-hours). Here is a link to the rather special spreadsheet which includes an energy audit, that N8GS has created to help size solar battery charging systems!

Ken, the best you should do is a SEARCH , there's 50 + posting on your question. JMO

I find that my 160 watt solar panel keeps my 2 AGM 12volt batteries fully charged.
