Buying Guide for the Best RV Solar Kit

Investing in RV solar kit can be a great way to cut down the cost of purchasing the individual components separately. However, you have to make sure the kit is capable of running all the appliances on your RV. There are so many more factors that you need to consider. If for any reason you choose to make your own search, the factors below will help you to make a good choice. 

RV energy requirement

The average daily energy consumption of most RV campers is 20 kilowatt-hours. Therefore, the first thing that you need to consider when choosing an RV solar kit is the power consumption of your RV. Calculate the capacity of your battery and choose a solar kit with the right amount of panels to effectively charge your panel.


The amount of space on your roof is another important factor that will help you to choose the right solar kit. If you don’t have enough installation space, consider getting a foldable solar panel which you can store safely in your RV when not in use. If you are going to mount your solar panel on the roof, make sure it has all the necessary mounting hardware.

Charge controller

Solar charge controllers play an important role in a solar system. They control how the power from the PV cells gets to the battery. There are two types of charge controllers namely PWM and MPPT. The newer MPPT technology is preferred in terms of power management to the PWM technology. However, it is usually more expensive. 

Type of solar panel

Most RV solar kits incorporate either monocrystalline or polycrystalline panels. While monocrystalline panels are usually more efficient, they are also more expensive. Polycrystalline panels are usually less expensive but bulkier. You need to weigh the options and find the balance depending on your available RV space. 


The weight of the solar panel is crucial. You don’t want to get a solar kit that will be heavier than what your roof can handle. This may lead to the collapse of your roof. 


It is always a smart idea to choose a product with a longer warranty. This can save you lots of headaches as well as help you to get the most value for your money. 

Battery compatibility

Some kits work with only certain battery types. If you already have dedicated batteries in your RV, make sure you get a compatible solar kit. 

Benefits of choosing the best RV solar kit

The benefits of using an RV solar kit are enormous. Firstly, it is a noble act of protecting the environment. It takes away the noise and air pollution of diesel generators and helps you to reduce your carbon footprint. Other benefits include;

1. Low maintenance: once installed, the only maintenance that you need is occasional cleaning the surface of the panels. The absence of moving parts means less wear and longer duration. 

2. Cut spending on energy: besides the initial investment, you don’t have to pay any more money to keep your energy running. If you are using a diesel generator, for example, you will need to spend regularly on diesel. 

3. Protect battery life: solar kits can protect the life of your battery by keeping it charged all the time. Manufacturers always advise that you charge your battery at least once every three months.
