Fitting a Solar Panel to your Campervan

As a general guide. On a sunny day, a 100W solar panel will produce approximately 4-5 amps per hour in full sun. This means that the solar panel would take around 18-25 hours to charge a fully discharged 100AH 12v battery. A solar panel half the size (50w) would take approximately double the amount of time to charge the same size battery.
