A 300 amp hour camper battery for instance would need around 300 watts of solar power.
How big of a solar panel do i need for a camper.
There are a lot of starter kits that include them like this one i m not affiliated just found you an example.
First off stop thinking in number of solar panels.
Solar panel systems have become increasingly popular over the past few years.
In my opinion the answer is simpler than you think but not truly defined but here are some choices.
There are 100 170 200 225 265 300 335 and 360 watt solar panels.
All solar panels serve a single purpose.
Divide both sides by 30 and you need 1 33 100 watt solar panels.
So from our camping experiment we ve determined that a 160 watt panel will keep our batteries topped off most days and that kit fits the bill.
How many solar panels do i need to power a camper.
If you have a compressor fridge and an inverter then go for 120w or above 150w if you have the space on the roof.

How to choose a panel.
To work out the size of the panel we need we simply take the 28 45 x 18v average voltage of a solar panel 512w.
Also keep in mind that solar panels experience a 75 90 drop in efficiency on cloudy days so it s good to have slightly more than you need when it comes to solar power about a 20 cushion if possible to account for less than ideal conditions.
The right size system can save you a ton of cash whether you have them installed on the roof of your home or the roof of your rv.
Our final personal determination.
Just substitute your loads and perform the same calculation.
