What are the best motorhome solar panels in 2019?

 

If you want to know right off the bat which solar panel we found best for RVs it’s enough to read the paragraph below, without going through the rest of the material. The Eco-Worthy L02P100N-CWMZ2-2 seems to come out on top in all the best motorhome solar panels reviews. Why? The short answer is that it offers a lot of bang for the buck. It comes together with a programmable battery charge controller and extension cable — besides the usual mounting brackets and connectors — which basically make it the perfect starter pack for those who want to get into solar panels. The 100 Watt power output is not to scoff at either since it will allow for a medium sized camper to get enough juice even on a moderately cloudy day. If this product is unavailable, we recommend you look towards the Eco-Worthy L02P160-1 160 W panels, for some truly impressive power output.

A short buying guide

 

Besides reducing the expenses associated with supplying a camper with electricity, solar panels also allow for greater freedom of movement, since the user won’t have to keep himself near an electrical source in order to enjoy using energy hungry appliances. What should you know before entering the age of free and renewable energy?

Monocrystalline vs. Polycrystalline

 

This feature refers to the technology used to manufacture the solar modules. As the name suggests, the reflective elements in monocrystalline panels are made out of a single silicon crystal grown to size. In terms of efficiency, these are the best camper solar panels to be currently found for sale but tend to come at a hefty price.

Polycrystalline panels are not as efficient, but they make up for it with a lower purchasing and maintenance price.

All crystalline panels are highly susceptible even to slight variations in solar output (bird droppings and insects can have a discernible impact) meaning they require constant cleaning in order to be kept at peak effectiveness.

This also increases the requirement for a good protective covering, to avoid the risk of damaging the modules while cleaning. Needless to say, all plastic or glass covers must undergo a special treatment to be made non-reflective.

 

Power output

 

This is mostly a matter of the user’s need and preference. Most campers don’t need a unit that generates more than 1000 W/h on a moderately sunny day since RV specific appliances tend to be pretty efficient and car batteries recharge as you drive.

We recommend you carefully measure your mean power consumption before deciding on what to buy and only shop according to your needs. There are a lot of guides on the internet to help you calculate the relevant figures and see precisely how much “wattage” you should aim towards.

It’s not really worth it to spend money on a product that over-performs. But it does, however, bear a mention that more powerful panels tend to be more effective when working under less than ideal conditions through gross power output alone.

 

Readiness and other factors

 

How easy it is for the product to be used straight of the box? Does it come with some stuff to get you started or will you have to purchase proper fittings or search for a compatible charge controller?

You’ll also have to check if the prospective buy is optimized for the voltage you generally work with since inconsistencies might diminish performance.

 

 

Our top picks

 

 

Eco-worthy L02P100N-CWMZ2-2

 

This Eco-worthy offer is more of a buy-together kit than anything else. For about the same as a pair of panels, you get your pair of panels AND a nifty battery charger controller, together with the usual stuff required for its installation.

The battery charger controller helps better optimize the output of the unit and greatly increases safety by reducing the chances of overload, under-voltage or reverse polarity occurring. Information junkies will probably love it since it provides accurate data on everything you want to know.

The whole kit is rated for 12 Volts, which means it works well with most car batteries.

As for the panels themselves, they generate 100 W each on a clear day and hold well to most things under the sun. They can withstand 2400Pa winds and 5400Pa snow loads, but being polycrystalline, they do require some maintenance to keep in peak condition.

 

Pros

This choice comes equipped with a corrosion-resistant aluminum frame that makes this product suitable to be used outdoors.

Because of its durable construction, this model can withstand snow loads as well as high winds. It is also resistant to water and sand.

It comes fitted with a compensation charge controller that includes an external temperature sensor as well as a USB 5V and a DC12V charging.

This option is quite safe as it includes reverse polarity protection. You can use it in all circumstances without fearing that your electronics might get damaged.

 

Cons

There was one customer who, even though he was happy with the quality of the panels, noted that the wiring leaves a lot to be desired. He was the only one who had this problem.

Some previous buyers said that this option is a bit expensive, which is a reason why some of those interested in it might not be able to afford it.

Eco-worthy L02P160-1

 

People that know themselves as big energy consumers might want to give a nod to Eco-worthy’s 160 W panels.

These are great for summer houses and hunting lodges, but in lower numbers can prove equally useful for campers that like to vacation in cloudier areas. They might not be able to handle Washington state but are sure to provide some extra oomph when you need it.

They also come with their own junction box to which by-pass diodes have been pre-installed so as to ensure a better low-light performance.

While its optimum run voltage is said to be at 18 volts, the manufacturer claims this unit is ideal for charging 12-volt batteries and more than one panel can easily be serialized to run at 24 or 48 V.

Since they’re expected to hold through some bad weather, the panels are supported by a sturdy anodized aluminum frame and covered in 3.2 mm of tempered glass.

 

Pros

Those who need a choice that can supply them with plenty of energy, should definitely add this alternative to their list.

It has a remarkable conversion efficiency of 150 watts. It can be used by those who own RVs, boats, cabins and even as back-up for homes.

The choice is also well appreciated by former buyers because it is effortless to install as it comes with pre-drilled holes. So, you just have to mount it in place.

Besides, the frame of this unit is made of corrosion-resistant aluminum. Therefore, this option can be installed outdoors as it won’t be damaged by the elements.

 

Cons

Some owners were not entirely happy with how this product does its job. According to some of them, this solar panel delivers a substandard performance.

One drawback that a handful of customers noted is that this unit has a rather flimsy frame. Not many buyers agree with this statement.

Eco-worthy L02M100-LCD-1

 

Eco-worthy also does monocrystalline panel kits for 12 and 24 Volts. Like their polycrystalline counterparts, these also come with a solar charge controller and everything you need for an easy install.

However, for about the same price, you get only one 100 Watt panel, but also the bragging rights of having the latest in solar harnessing technology on the roof of your camper.

The solar charge controller can govern up to four 400 W of total output, or in other words, four 100 W panels.

Considering the ideal 500Wh that one panel can generate, this would make for a rather impressive 2000Wh, enough to take care of a television, a fridge, and washing machine.

The L02M100 has the same good endurance as its more affordable cousin.  It sits on a hard anodized aluminum frame and can withstand 2400Pa winds and 5400Pa of snow.

 

Pros

This product consists of a 100W mono solar panel, 30 30 ft. of cable that features MC4 connectors, a 15A controller and mounting brackets.

Plus, keep in mind that this choice is ideal for 12-volt battery charging. You can wire two or more panels in series for 24/48-volt charging.

It comes provided with the Z brackets that you have to use to set this option in place. The frame of the unit is made of aluminum and, thus, it will not corrode.

This innovative panel delivers results, even in low light environments and comes with pre-installed by-pass diodes.

 

Cons

Given the minimal features that this option includes, some of its former customers have pointed out that this kit is a little overpriced. As expected, not all buyers agree.

This device does not come preinstalled. Therefore, you have to spend some time putting it together before using it for the first time.

Buy from Amazon.com for ($139.94)
