The most asked question by motorhome owners when they think of converting their motorhome to a PV module is “How much solar do I need for my RV?” Well, it depends on your daily energy consumption, your roof space, and the number and size of the panels you are getting.
How Much Solar Do I Need for My RV?
In today’s guide, I will break down everything you need to know before going full solar for your camper, from panel size to number to keep your appliances running and stay powered. So, let’s get started with how to calculate the right setup for your needs.
Factors to Consider
It’s important to understand several key factors before deciding on your PV setup. Let’s take a closer look at these.
Peak Sun Hours
How many of solar panels do you need for your camper depends on the peak sun hours you get in your area each day. Generally, when the sun is at its peak in Vancouver and Portland, PV setups produce 100 Watts to 400 Watts of power. So, if your area gets 5 to 7 peak sun hours, it will be enough for your RV to run without any other power source.
Your Power Usage
Planning RV solar installation? Your total energy use is the biggest factor in deciding how many solar panels you will need for your motorhome. Every appliance you have in your motorhome, like your fridge, lights, or AC, draws electricity differently.
To determine how much solar power you need to run your system, you need to calculate your needs. Make a list of your appliances, calculate the wattage of everything you plan to use daily, and multiply by the number of hours you use them. This gives you an estimate of your energy consumption, and through this calculation, you will know how many PV module panels you will need to power an RV.
Solar Panel Size and Output
Choosing what size setup will work for your rig depends on your roof space and energy demand. A standard 400W panel can generate 1.6 to 2.4 kilowatt-hours (kWh) of electricity per day under ideal conditions, but the energy production may vary depending on the weather or your location.
If you are wondering how much solar energy you need to run an RV AC, keep in mind that air conditioners consume a lot of energy. They often require 1500 to 2000 watts of panels and a battery that can store 800+ amp per hour. However, for a small to moderate setup, 200 to 400-watt panels are enough.

Yes, it is enough if you own a small rig or have limited energy requirements.
What will a 400 watt PV panel run in an RV?

Will a solar panel run an AC in an RV?
Yes, it can run AC in your motorhome. However, AC consumes more power as compared to other appliances, so you will need more panels and a large battery setup to run an air conditioning system in your camper.
