How many watt solar panel do i need camping.

This is also assuming of course you have a lot of battery power too. Start off with 100 watts. First enter the capacity of the solar panels you think you will need. But i have seen plenty of 160 watt panels.

5 hours of direct sunlight x 6 amps generated hour 30 amp hours day. The spreadsheet looks complicated but in reality it is very simple to use. 100 watt portable solar panel. This is assuming you are considering using 12 volt rv grade panels.

Panel specifications the power rating of panels varies depending on the model and manufacturer but most range from 250 watts to 330 watts. Homes use a lot of energy and they generally require a solar system sized between 5 kw and 10 kw that s 5 000 10 000 watts. A 300 amp hour camper battery for instance would need around 300 watts of solar power. 100 watt solar panel approximately 6 amps hour in direct summer sun no clouds here s an example of our calculation of how much the solar panels are generating to recharge our rv batteries.
