In the beginning, I should tell you that solar energy is not really free as there is a cost to pay for the solar kit. Although after that you do not have to pay for the energy.

Another thing is that the solar panels do not replace your RV battery as they are only another way to charge them, such as a generator or off-grid power would do.

Solar panels come in rescue when you are camping off-grid and you need an additional way to charge up your battery to save fuel. Many RV owners are going solar due to its added benefits.

let’s find a suitable solar panel kit for your next RV adventure!

What is RV Solar Panel?

RV solar panel is a word used colloquially for photo-voltaic or PV modules. These cells are fitted into a frame to make panels. When these photo-voltaic cells are exposed to sunlight they generate DC electricity.

It’s a one-time investment as the panels keep working for a long time depending upon the maintenance and quality of the product. It provides energy from the sun besides lowering your dependence on fossil fuel.

You no longer will hear generator noise and your batteries will get charged. At first, it will cost you a bit more but later it will pay you slowly but steadily.

How Do RV Solar Panels Work?

Solar panels work by allowing photons or particles of light to knock out a free electron from the atom, which generates a flow of electricity. A solar panel is made up of many smaller units known as photovoltaic cells.

Photovoltaic cells are actually made up of two slices of semiconductor material usually silicon. For the photovoltaic cells to work it has to make an electric field.

During the manufacturing process, silicon is doped with other materials which give the two slices of positive and negative electric charge.

Power output depends upon the number of solar panels you fit on your RV.

The solar kit also has a charge controller which transmits power generated by the solar panels to the RV battery. The charge controller is useful to regulate the amount of charge reaching your battery as you can control it to avoid overcharging.

The electricity from the battery is DC or direct current whereas most of the devices and appliances running in your RV run on AC or alternating current. To change DC to AC you need an inverter.

What is a charge controller?

A charge controller is a device that controls the power entering the battery and protects both solar panel and battery from damage.

The power that is generated in the solar panel can be high or low to ensure that the battery does not get damaged during the process. It also ensures that many panels work as a single unit during power generation.

The solar kit also has a device called an inverter which converts DC to AC as most of the appliances on your RV run on AC.

A charge controller controls the charge coming from different power sources such as solar panel, generator, or shore power.

The best charge controller is equipped with “Pulse Width Modulation or PWM. It can regulate the speed and width of the pulses which charges the depleted battery sooner.

Important Factors to consider before purchasing an RV Solar Panel

All solar panels are not equal in power output, durability, efficiency, portability and the list goes on, that’s why their prices also vary. Let’s see some important criteria which you should see before buying a solar panel for your RV. It will make sure that it works fine and fulfill your power needs.

1. Efficiency

A highly efficient solar panel will do the work in less time or you can say in less exposure to sunlight it can generate a larger amount of power.

An efficient solar panel takes needs less space.  The efficiency of a solar panel is measured in percentage as the amount of sunlight that can be converted into electricity.

During your process of selection keep in mind about the power output this is also important as the amount of power depends upon the solar panel size and efficiency. So, if the efficiency is less then you would need a bigger panel for the same required power output.

The efficiency of a solar panel also depends upon the type of solar panel. Generally, the cheapest ones are less efficient than others.

Efficiency of different types of solar panels

Amorphous solar panel7% to 10%
Polycrystalline solar panel15%
Mono-crystalline solar panel20%
Concentrated PV Cell or CVP41%
Efficiency of different types of solar panels

2. Solar Panel Wattage

Solar panel wattage is defined as the current that it can generate. A higher wattage solar panel will fulfill the power need of appliances on board. Higher the wattage, the faster the charge.

However, before buying a higher wattage solar panel you must look at the voltage that you may need as these solar panels are costly.

3. Geographical Location

How much power you can harvest from the solar panel will depend upon the exposure of sunlight. If you travel to places where sunlight is low then opt for a highly efficient solar panel as it can provide enough power.

Places such as the north of the country receive less sunlight where you may need an efficient solar panel. Climate is also important as during summers sunlight is more than the winters.

4. Portability

Portability is another factor that may play a major role. If you frequently go out for RVing then a compact and lightweight solar panel kit will be handy. During moving in and out they can get damaged.

Investing in the most portable unit will extend the life span of the product.

5. Durability

The durability of a product ensures that you have invested in a good product that will serve you for a long. Durability depends upon the quality and maintenance of the product.

Maintenance is on your hand and quality depends upon the manufacturers. We have tried our best to pick those solar panels kits that have sufficient and good customer reviews.

6. Dimensions

As we have said earlier that the size matters for the solar panel but you have to see whether or not you have sufficient space for the solar panel to get it installed.

Know the measurement of the roof before purchasing a unit as you may end up with the wrong size. The product has to compete with other devices on the roof such as AC and antenna. If you have space and budget then go for a large one as it will increase power supply.

7. Weatherproof

Solar panels for most of the time will remain outside. High winds, dust, and snow load are the possible reason for the damage. Look for the weatherproof product.

8. Expandability

Last but not the least point to consider is the expandability of the solar power. If in a year or two you need to upgrade, will the system is pre-ready for it. Most of the listed units have the ability to expand where you can attach new solar panels to increase the power output.

Types of solar panels

There are three types of solar panels available in the market today. Before buying you should look at the advantage and disadvantages of different types of solar panels. Let’s see what are they.

PolycrystallineLow costLower lifespan, Less efficient, Sensitive to high temperatures
MonocrystallineHigh-efficiency rate, Optimized for commercial use, Longer lifespan Costly
Thin-filmPortable, Flexible, Lightweight, Lower-costLowest efficiency and shorter lifespan
Concentrated PV CellVery high performance with higher efficiency rateSolar tracker and cooling system installed for higher efficiency

1. Polycrystalline

Polycrystalline solar panels or Poly-SI are the first generations of solar panels. These types of solar panels are easily recognized by their square panels and angles are not cut. It also has a blue and specked look.

Their price is low and also has lower efficiency. They tend to has a short lifespan because they are affected by hot temperatures.

2. Monocrystalline

These types of solar panels are made up of the purest form of monocrystalline silicon. They have a uniform dark look with rounded edges. The high purity of silicon make’s it highly efficient.

They have high power output, occupy less space, and life span is the longest among other types of solar panels. These types of solar panels are expensive because of the material used in it. Monocrystalline solar panels have a longer life span because they are less affected by high temperatures.

3. Thin-film or amorphous

These types of solar panels are made up of placing one or more films of photovoltaic material such as cadmium, silicon, or copper.

One of the less expensive options, coming from the second generation of solar panels. Although, they have some advantages such as flexibility and are less affected by high temperatures.

Disadvantages such as taking a lot of space and a shorter lifespan than mono and polycrystalline solar panels make them less desirable.
