What Do Solar Panels Do For An Rv?

The main purposes of the solar panel are to save the energy from the sun and then converted into the battery through the charger controller. Here the charger controller plays a great role in the whole system. This portion is like a heart for the system. So, when you want to use the panels on RV, it helps to run other appliances inside the van.


When people are planning for a tour with their RV, they need to use several kinds of appliances in the van. And to run those appliances, you need power, which may come from the battery. It’s not possible to complete the tour by depending on fuel. That is why people go for solar panels. These panels not only consume energy for a longer period but also you can save so much money as this power comes from natural sources.

These solar panels basically help to run all the electronic appliances that are used on an RV van. You can run a fan, tv, charge your laptop, mobile, run the coffee machine, sandwich maker, etc. and many more things. You can run all the things that are related to the inverter or connected with the batteries.

How Much Solar Power Do I Need For My Rv

To calculate the amount of power for the solar panels on RV, you need to make a list of the appliances that you are going to use on your RV. This calculation will give you a proper idea of how much power you need. And which battery, inverter, or the charger controllers you need to set up on your RV.

You can control the uses by using power-consuming appliances. Instead of the lightbulb on your RV van, if you use the LED light, it will save the energy and give you more power to use other appliances. Another example can fully clear your concept is, if you need 50amph per day, then you need a solar panel that can produce 100 watts. These 100 watts can be used for 6 hours per day if you use 65.15amp per hour.

This is the basic calculation for 100 watts that can be produced from the solar panels. You can increase the solar panels on the RV if you want to use more appliances, or you need more power than 65.15amp per hour.

How Many Solar Panels Do I Need For My Rv?

You cannot expect the exact number of panels to run the appliances on the RV. Or, you will not get the accurate answer to the question of how many solar panels do I need for my RV? Because the number of panels will not determine which appliances you can run or not. This whole calculation is based on the watts. Here we will give a shortlist of the common appliances. So that you can understand which appliances you need to use and for how much time.

AppliancesPower Consumption (W)Usage Time (Daily)
Bulb60 W6
Mini Fridge200 W24
Microwave800 W5
TV200 w4
Fan60 W6

By reading this chart, I hope you will understand how much W can be used daily and for how long. This calculation will lead you to choose the number of solar panels to set up on RV.

If we calculate the power consumption in KW, then for 600KW appliances, one solar panel is enough. Again for 3000 KWH power consumption, you will need almost 10 solar panels. It’s totally up to you now how much appliances you will run on the RV. If you don’t run the most necessary appliances, whenever you need them, then it will give you a great backup.

Again, there is a fact, due to weather, you may not get the sunlight all day long. This is also a fact that how much your battery will recharge and provides you backup.

How Does A Solar Panel Work On An Rv?

Your solar panel will perfectly generate power when you perfectly set it up. To set the solar panel, you need a charger controller, an inverter, battery, and to connect all that equipment, you will need some connectors.

Now, when the solar panels consume the energy, it delivers all the energy on the charger controls. This charger prevents overcharging and distributes the power to the solar battery for storing the energy. There is also an inverter that converts that power into DC and AC electricity to run the appliances.

This is the actual working process of a solar panel on RV. Now, it depends on you what kind of appliances you will use in the van. These will determine how many you need to set up on the RV.

Final Thought

Going on a ride with your RV van is a great experience. To get a greater experience, you can add the solar panels to your RV. These panels will not only minimize the cost but also give you an experience that you will never forget.

How many solar panels do I need for my RV can not be described in a word; we already discussed that? What you can learn is how much watts you actually need to run your necessary things on the RV with solar panels. Based on the appliances and the watts, you need to select the solar panels in number.
