Solar panel size

You would need 2x GP100W Bi-Folds and 200 to 300 Ah of battery capacity. - You also need sun ;-)

.... But don't be cheap with the solar regulator. You'll be investing considerable sums on the batteries (and panels).

Look into a smart regulator such as the Plasmatronic PL 20, 40, 60 series to ensure that YOU know exactly what's happening with your system.

we run an Engel 60l as a fridge and Engel 39L as a freezer

2 x 100 ah AGM deep cycle batteries (alternator also charges them)

4 x 75w BP panels ..... slight over kill but we have them hinged in pairs and place one pair facing the morning sun and one pair to pick up the afternoon sun. This way we dont need to manage them as we spend a lot of time away from the camp during the day walking etc and we can maximise the available sun

Be aware that your panels do need to be managed as the sun direction needs to be constantly monitored and panels shifted to maintain charge.....it is not as simple as reading off a chart for sun hours X panel capacity......that is the theory assuming the panels are always facing the sun (ie tracking) ....not reality in a camping situation..you wont get that sun hours on your panel face left stationary all day.

as Derek stated the panels size he quoted will suit fine but manage them or they may dissapoint.......regardless of where you are there a cloudy days and it is those days that you need the battery capacity for..we can run about 4 days with no charge in ambients low 30's starting with full batteries but our fridges are well insulated and the canopy is also insulated

As others posted use a very good solar controller..we use a PL20 and the alternator charge runs through a shunt

you are going to spend some serious money..spend it wisely on good gear and make certain whoever advises you on the ultimate purchase and whoever does the wiring does know their subject...
