With the aid of this solution, RV owners get the chance to enjoy the amenities of home. Here are the factors that you have to consider in your search for good solar panels:

Efficiency – Despite all the amenities and facilities that you can have onboard your RV, remember that its space is still less spacious if you compare it to your home. With that in mind, you need a highly efficient solar panel – one that makes use of only a little space while still maximizing its output.

Also, remember that the efficiency in solar panels for camping trailer and RVs can be defined as the specific amount of solar energy converted to electricity. Such amount is usually reflected in the form of a percentage.

When searching for the best solar panels for RV use, make sure that the electrical output is sufficient enough for the onboard electronics in your RV. You will instantly know that the solar panel is highly efficient if your RV will receive enough voltage. When identifying the efficiency of a solar panel kit, check its type.

Note that solar panels come in three different types with each one having varying efficiency based on its make. One type is the amorphous solar panel. It is the most inexpensive type but take note that it is also the poorest in terms of efficiency.

You can also pick the polycrystalline type with an efficiency rating measured at around 16 percent. This specific type produces two times the current created by the amorphous type. The third type is the mono-crystalline, which has an efficiency rating of more than 16 percent. Such efficiency is a bit higher than polycrystalline.

Wattage cells – Your chosen solar panel’s wattage can be defined as the current that the solar panels are capable of outputting. You can determine such wattage based on the current that every cell within the panel can output.

It is actually beneficial to have an RV solar panel with a higher wattage as it also means that it can produce current capable of supporting numerous electrical activities. A higher wattage can also guarantee a higher efficiency rating each time you connect your electronics and appliances to the source of current.

However, prior to choosing to buy high-watt solar panels, make sure that this is the voltage that you need exactly. It is mainly because these solar panels are often expensive. It would be best to choose a small solar panel at first. You can just upgrade into a 2-panel set later on.

Portability – Another contributing factor in your final decision is the portability of the unit. Remember that it is crucial to invest in the most portable solar panels for RV. It is mainly because you will need to carry it to your RV from time to time.

It is also advisable to pick portable RV solar panel kits as these promote ease of installation. If unfortunately, you have chosen a solar panel kit, which is a bit big, then a wise tip is to opt for one that is already equipped with cables as such promotes ease of movement.

Reliability especially when you are on the road – One of the major advantages of installing an RV solar panel is that it is capable of offering a more reliable and convenient source of electricity once you start driving on the road. Some of the systems offered today are, fortunately, inexpensive.

They are also capable of providing more than enough power designed to recharge the battery of your RV. You can also find more robust systems capable of providing a more reliable source of power for radios, lights, televisions, and appliances.

Once you are prepared to invest in a solar panel, take into consideration its reliability and efficiency. You should then consider starting with a small set with two panels. Avoid making the mistakes committed by RV owners who tend to overestimate their needs by investing in a larger solar system.

It would be best to start small at first. Note that if you start small then you always have the option of expanding once you figure out your specific energy requirements later on.

Geographical location – Another thing to keep in mind is that your present geographical location has a say on the specific type of solar panel kit you specifically need.

In case you encounter sunlight problems because of your current location, ensure that you choose a highly efficient solar panel kit. A highly efficient solar panel is a major help in dealing with sunlight issues.

Durability – While it is true that solar panels are prone to aging and wearing out, make sure to buy one, which is highly durable so it will last for a long time. Avoid going for cheap and low-quality ones as these might only serve you for the short term.

They tend to wear out too soon, causing you to buy a new one frequently. This is not actually helpful if you are planning to save money.

Frequently Asked Questions (FAQs)

RV Solar Panels Reviews

What are the different types of RV solar panels?

Solar panels actually come in three common types. There is the mono-crystalline solar panel, which is constructed from one large silicone crystal. It is considered to be the most efficient while having the ability to yield a higher charge output. It is also capable of producing a higher amount of power in low-light conditions.

Another type is polycrystalline, which comes from silicon blocks containing a few small solar crystals. It produces approximately one percent less power when compared to mono-crystalline solar panels. Polycrystalline is also one of the most commonly used types of solar panels today.

Also called the thin film, amorphous is the third type of solar panel that you can pick. It makes use of silicon, which creates a panel by spreading it on a large bed. It is the most inexpensive type.

However, it also yields the least power output among the three types. While it functions well, note that it also needs about three times the roof space used by mono-crystalline and polycrystalline for just a similar power yield.

How do RV solar panels work?

RV solar panels work by converting sunlight into electricity or power. The panels create an electric current each time the sun hits them. The produced electric current is then fed into a charge controller. This is the one that will control the amount of current that gets into the battery.

After that, the batteries will create DC power. There is also an inverter, which converts the DC power into AC, which is the specific type of power you need to operate items, such as laptops, phone charges, and blenders.

What are the benefits of an RV solar panel?

One of the major benefits of installing a solar panel in your recreational vehicle is that it is easy to use, quiet, and easy. It does not consume fuel nor give off waste. The fact that there are zero moving parts also means that it does not produce any mechanical noise. Solar panels also work in maximizing the life of your battery.

It is mainly because solar panels are capable of generating pure DC power each time you expose them to the sun. That’s what your batteries specifically prefer. With the solar panels around, you also have the chance of parking wherever you want.

You can gain electrical independence since you know that you will receive power anywhere. Aside from that, they are beneficial as they are safe and reliable to use while requiring the least amount of maintenance.

What are the types and purpose of a charge controller?

If you are planning to install a solar panel into your recreational vehicle then take note that you have three options. The first type is the simple 1- or 2-stage controller. It comes with shunt transistors designed to regulate the voltage in just one to two steps. The main purpose of this controller is to short the panel when a specific voltage is reached.

The second type is the pulse width modulated (PWM) controller. This charge controller is known as the traditional form, which is also considered as the industry standard at present. Lastly, there is the MPPT or the maximum power point tracking.

This controller works by identifying the ideal voltage and amp of a solar panel exhibit. This results in an additional power, around ten to thirty percent more of the sun-oriented cluster.

With the help of any of these charge controllers, you will have full control over the voltage of your device. It also opens the circuit and halts the charge just in case the voltage of the battery gets higher than a specific level.

How many solar panels are needed to run an air conditioner?

The answer to this is actually dependent on the specific amount of power consumed by your air conditioning unit. In most cases, though, RV owners need around three to four solar panels. Such number is enough to give enough solar power for RV air conditioner.

How much solar do I need on my RV?

One way to compute the specific power requirements of your RV is to boondock without using an AC generator. You will find that useful in determining the length of time it takes to make your vehicle run with normal usage and without the use of any generators, only batteries.

In case your batteries consumed up to 3 days to drain, then take note that such batteries are capable of supplying approximately 200 amp-hours of energy, which you can derive. One issue with this is that you are only allowed to utilize approximately 75 percent of such energy.

With that in mind, only around 150 amp hours are what you can use. Divide such figure by the length of time spent for your batteries to drain during the time when you boondock. That means you have to divide 150 amp-hours by 3 days. The result is 50 amp-hours, which specifically determines the specific energy consumed regularly.

It should be noted that a 100-watt solar panel can produce approximately 6 amps per hour of having the sun at its peak. You can translate this to around 30 amp-hours every day. That said, there is a chance that you will require two 100-watt solar panels to either recharge or supply full power to your vehicle every day.

How to size my RV solar panel system?

Sizing an RV solar panel system is actually doable if you are fully aware of how it is done. The first step actually involves identifying the appliances that use AC and DC power as well as the specific number of hours each one operates or runs daily. The next thing to do is to compute the total amps every week.

The figures that you use should be the total amp hours daily that you need to multiply by the specific number of days every week. After that, you should consider matching the total amps every week with the ideal solar power solution.

Do I require additional hardware?

Yes, there are certain items and hardware that you will need to use when it comes to installing RV solar panels. Fortunately, most of these items and hardware already form part of the best RV solar kit.

Some of the hardware and items you might need for the installation are T-knobs, mount adapters, rocker mount sets, mounting L-feet, sealant, tape, and tilt bar sets.

What are good RV solar panel brands?

  • Renogy
  • WindyNation
  • HQST
  • ALLPOWERS
  • ACOPOWER
  • Newpowa
  • Go Power
