For our specific power demands we need one 100 watt portable solar panel to recharge our rv batteries during our boondocking camping trips under normal conditions.
How big of a solar panel do i need for a camper.
A 300 amp hour camper battery for instance would need around 300 watts of solar power.
First off stop thinking in number of solar panels.
Just substitute your loads and perform the same calculation.
After that preamble we get to the key question how big a solar panel do i need.
Divide both sides by 30 and you need 1 33 100 watt solar panels.
Solar panels are measured in watts.
How many solar panels do i need to power a camper.
But i have seen plenty of 160 watt panels.
It really comes down to efficiency.
How to choose a panel.
Why are there types to choose from.
Now as i said before this is a high power example more typical of a large offgrid caravan or motorhome but the approach is the same.
How much solar power do i need for my rv.
They allow a user to harvest energy from the sun and turn it into electricity.
We ll begin with how solar panels on an rv work to give you a clear idea of what this type of setup entails.
Solar panel systems have become increasingly popular over the past few years.
Now i ve not seen a 133 watt solar panel for sale.
We have four 100 watt polycrystalline panels installed on the front section of our camper s roof.
In my opinion the answer is simpler than you think but not truly defined but here are some choices.
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.
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.
If you have a compressor fridge and an inverter then go for 120w or above 150w if you have the space on the roof.
There are 100 170 200 225 265 300 335 and 360 watt solar panels.
All solar panels serve a single purpose.
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.
