Thread: Camping Solar Panels

Hi

The important thing as long as you have the right volatge set up, is the number of amps, they are what provides the power.

Lets says you have a 200AH battery and you draw 5 amps for 10 hours, in theory that will discharge about 25% of the battery. But due to inefficiency in the system, you will need to deliver at least 10& more amps back to the battery to restore it to fully charged

So it depends a bit on your setup and how much current you draw when the panel is not providing power.

I would suggest at least a 240W panel, that will deliver about 6 amps @ 12V.

I have a 130 ah battery in the camper trailer it runs the engle & lights and what ever ,

I have a 120 watt panel , I quite often go away for 4 days and never run out battery running everything listed .
My thoughts a minimum 120 watt panel it has worked for me

I run a 40ltr engel,led lights and charge phones ect on a 100 ah deep cycle battery.Full sun my 80 watt panel fully charges the battery by mid afternoon,but i would say 120 watt would be better.

Just been through the same thing

After much thought and discussion

With grey nomads mates ect installed

A 200 watt panel (on special ebay $215 delivered)

A 10 watt controller from same source

Then purchased a AGM 105 amp battery

They are expensive but they last a long

Time ($330) then bought some sikoflex (maybe spelt wrong)

And glued the panel to roof via some aluminum

Angle runs my 55 liter fridge laptop and lights and radios

When camping with ease

100 Watts

Then which type comes into play. If you believe the destructions, the new blankets have less reflection and more absorption than the panels, so apparently better charging output.


I have 120w panels, seem to do the trick without a fridge for about a week plus with leds, water pump and charging young blokes i-pad thing.

A good case study is documented here.

You do know how big a 240w panel is?
