what is the best size solar panel for a motorhome

Choosing the right size solar panel for a motorhome depends on your energy needs and available roof space. Most motorhome owners opt for panels between 100 to 400 watts, with 200 watts being a common starting point for moderate use. The size you need is determined by how much power your appliances consume and how much sunlight your panels will receive.

If you run basic devices like lights, a fridge, and a few small electronics, 200 to 300 watts may suffice. For larger setups with air conditioning, microwaves, or multiple devices, 400 watts or more might be necessary. Always calculate your daily watt-hour usage to ensure your panels can keep up with demand.
