Remember to account for occasional high-power items or extra guests.

Calculating Solar Panel Output for Your RV

Now that you know your energy needs, let’s talk about solar panel output. Panels are rated by the wattage they can produce in an hour of direct sunlight. To figure out how many panels you’ll need, divide your daily watt-hour requirement by the number of peak sunlight hours in your area. This gives you the total watts your panels need to produce. Remember, it’s better to have a little extra than not enough, as conditions aren’t always ideal.

For instance, if you need 1500 watt-hours per day and you get 5 peak sunlight hours, you’ll need 300 watts of solar panels.

Check the wattage rating on potential solar panels.
Estimate the average peak sunlight hours for areas you’ll visit.
Divide your daily energy requirement by peak sunlight hours for total wattage needed.
Consider efficiency losses and opt for a bit more wattage than the bare minimum.
