We have already made a big decision to upgrade your RV with solar power.  You may already know about solar energy and like it.  How much of your solar energy is needed, how many panels are needed, and in what size work can be done, and in this case how many days can be done?

If you are looking for voltage watt amperes etc. then we can help you according to your need.

First, you need to know what you need or what you don't have, then it is important to set up solar energy.

You can use solar panels in every place of your motor home if you want.  But you need to know how much energy the solar panels save, otherwise, you may be financially disadvantaged.

If you find that the battery does not last as long as you need it, you can add a battery bank to it.  But when adding extra batteries, keep in mind the size and weight of your meter home.  These are very important issues.

If you have a good Arabic solar system, you can charge 30 amps all day in the sun, it can charge 300 amp in 10 hours.  You need to keep an eye on the battery level. Lead Acid batteries should never be used below 50%.  Battery durability may be reduced.

The important thing about how your solar system will work with your RV is the ashes.  The three components you need to use solar energy are size, battery bank, and electrical connection.

RV solar panels can be used while driving.  Air conditioners can be run along with conditioners.  But it depends on what power you are using to run the air conditioning.  Dash air conditioning can run all the time it is not a problem.

You can easily use RV solar panels in your home or car.  It is easy and can be financially rewarding.  Money is spent less.  If you do not get the voltage you need, you can use a battery bank as support.  Which will make your life a lot easier.

RV solar panels can be used anywhere in the house or car using battery-powered solar power in different countries is becoming quite profitable.

This is a solar system designed for medium size RVS.

  1. TYPES OF LOADS.
      There are following 2 types of Electrical Loads present in an RV;
  2. AC Loads – 110 Volts AC Voltage  

     b.DC Loads – 12 Volts DC Voltage.

  1. The Typical Loads on a Medium Size RV and their consumptions per day.

 

  Item Average Watts Average Amps Minutes Used Per Day Hours Used Per Day Amp Hours Per Day
1 Air Conditioner 1200 100 60 1 100
2 Laptops - 18 300 5 90
3 Coffee Machine 800 67 20 0.3 22
4 Juicer/Blender 500 42 10 0.2 7

6 Drones - 4 60 1 4
7 Cell Phones - 1 180 3 3
8 Cameras - 1 60 1 1
Total Amp Hours 233

The Items written in Bold are DC devices but, they utilize a power adapter to convert ac power in to DC. Hence they are listed in AC loads.

     b.The DC Loads.
