Hi Jessica,
The mobile solar energy can be used for the same things that a static solar power system would – to get an understanding of what this might be, it is good to refer back to the Bushlight system, and to review what those systems cater for; several lights, fans, basic appliances. The benefit of a mobile solar power supply is that it allows rangers greater flexibility in their operations.
I’d recommend taking a look at previous questions that have been asked in this forum about mobile solar energy, in particular the two answers I’ve linked below can give you an insight into energy usage and requirements.
