What amazed us about the WindyNation is that all the items in the kit worked adequately straight out of their packaging. We measured the voltage that the system delivered to our battery, and it read a steady 12.9V. The installation instructions are also easy to read.

We also tested the WindyNation on a cloudy day. It was still able to draw power from the sun and direct it to our battery. Some systems that we have tested all seem to shut off the moment the sky turns overcast. You will not have to park your van under direct sunlight to draw solar energy. You can still generate power even if you are under the shade. Of course, do not expect that its solar efficiency will be the same.

This solar panel already comes with the essential accessories to help you get started on your off-grid lifestyle. The charge controller features adequate weather protection, while the cables are long enough for connecting the system.

The WindyNation solar panel kit would have earned a 5-star rating from us if not for its lack of fuses in the charge controller. It is something that you will need to buy separately. It would have been better if WindyNation also provided the fuses so that you can install the system right away.

While not having a fuse may look like a big deal to some, most users of the van dwelling solar power system feel it is something that they can ignore. After all, it is not very often that you get a nearly-complete package for the price of a conventional solar panel.

11. HQST 100-Watt Polycrystalline Solar Panel

  • Right photovoltaic technology for more efficient solar energy absorption and conversion
  • Reliable construction for strength and durability
  • High power output for different applications

The HQST Polycrystalline solar panels for vans are an excellent choice for folks who want an economical solution to their solar energy needs. While the HQST are inexpensive, they are never remiss on their capabilities to absorb and convert as much solar energy as possible.

Indeed, polycrystalline photovoltaic cells are nowhere near the efficiency rating of monocrystalline units. However, our assessment of the HQST reveals that the product can perform a lot better than some Mono solar panels on the market. You get to enjoy the affordability of Poly panels, while also benefiting from the high performance of a Mono unit.

Our tests revealed that the HQST can churn out about 450Wh per day. This is quite close to the company’s published 500 Wh power efficiency. The addition of bypass diodes helps reduce the incidence of power fluctuations because of changing light conditions. On that note, we found the HQST to work surprisingly well in low light conditions.

We also like HQST’s construction. We could tell that the company paid extra attention to the overall development of the panel’s frame. The other components of the solar panel are also designed with excellent weatherproofing. Even if you were to travel in snowy conditions, you could still rely on the HQST solar panel to retain its integrity.

While affordability is one of the HQST’s inherent strengths, we find it troubling that the company only includes the solar panel in the package. It does not come with an assortment of cables, clips, and the all-important solar charge controller. On the bright side, you will get to choose a more appropriate charge controller for your system. You will not be limited to which the company provides you.

The HQST Polycrystalline Solar Panel may not have the accessories to complete your setup. However, with its high solar efficiency and robust construction, we still consider it a good buy.

What Is A Solar Panel For Van And Who This Is For


A solar panel for van is exactly what the phrase implies. You have an array of photovoltaic cells mounted on the roof of your van. Electrical wiring connects the photovoltaic panel to the battery bank and a solar power inverter. The setup then delivers an AC type of electric current to the different outlets in your vehicle. You can then power up your mini-refrigerator, microwave oven, a television set, and other appliances like you would at home.

The number of appliances in your van that you can hook up to your solar system depends two essential things. One is the power requirements of the devices you want powered by solar energy. The other one is the overall voltage output of your solar system.

The performance of your van-mounted solar system depends, in part, on the overall voltage output of the system. Hence, you will want to use a solar panel that has a high energy efficiency rating. You will want it to absorb as much of the sun’s light and convert it into usable AC current.

A solar panel for van is for people who love to spend a more convenient time away from home. They can be campers, RVers, or road trippers. Hunters and vacationists can also benefit from such a setup. It gives you all the modern conveniences you can imagine without becoming dependent on traditional electrical power sources. Solar panels for vans and RVs let you enjoy living off the grid. They guarantee a more comfortable life away from home.

How Does It Work

A solar panel for van is not that different from the solar energy systems we see in other settings, such as commercial establishments, local homes, and industries. The main difference is that a van solar system is ‘mobile,’ literally. It goes wherever the van goes.

Solar panels come with very specialized cells that gather or absorb the energy coming from the sun. The more intense the sun’s rays are the more energy that the photovoltaic cells can collect. However, keep in mind that different photovoltaic technologies have varying degrees of solar energy absorption efficiency. There are technologies that are more efficient in absorbing the sun’s energy. That is why it is critical to choose a system that will give you the most amount of solar power in terms of voltage.

The PV cells in a solar panel absorb sunlight. The photovoltaic cells knock the electrons in the sunlight loose. These loose electrons are what we call ‘electricity’. The free electrons then flow as electrical current. They go to a collecting mechanism in the solar array. From here, the electric current gets transferred to the wires and into the other parts of the solar energy system.

You cannot use the electricity from the solar panels without first converting it into AC electricity. A charge controller delivers the right charge to your deep cycle battery. An inverter connected to the battery turns the DC electricity to AC electricity. Only then can you start using the electricity to power up the devices and appliances in your van.

You can use your coffee maker and your oven to make a delicious breakfast while enjoying a fascinating view of the landscape. It is also possible to hook up your entertainment system. Watch movies and listen to your favorite songs without ever draining the battery of your van.

What Are The Different Types Of Van Solar Panels


There are three common ways in which we can classify solar panels for vans. The first is according to their form factor, whether they are flexible or rigid. The second relates to their manner of installation. The third way we can categorize van solar panels is by the type of their photovoltaic cell construction. Let us look at them one by one.

According to Form Factor

  • Rigid

Many of these solar panels come with an aluminum frame and are perfect for outdoor use. They are also easier to clean and are more weather-resistant than flexible types. They are ideal for people who want a durable and high-performance solar panel for their van.

  • Flexible

Most van owners choose this type of solar panel because it can conform to the natural curve of the vehicle’s roof. The only issue with this solar panel is that it is not as durable as a rigid type. It is also more vulnerable to scratches.

According to Solar Panel Placement

  • Fixed

One advantage of a fixed solar panel on a van is that it is always collecting solar energy. If the sun is up in the sky, it will continue generating power and storing this into your battery bank. The problem is that it requires significant installation work on your vehicle.

  • Portable

The top-tier thing about a portable solar panel is that you can position it anywhere where the sun shines best. You can park your van in the shade and position the solar panel elsewhere. The downside is that you will need to set it up every time you stop for a break.

According to Photovoltaic Cell Type

  • Monocrystalline

This type of photovoltaic cell features single-crystal silicon. This allows electrons to move more efficiently. Hence, they are more efficient in generating electricity. The downside is that monocrystalline solar panels are expensive.

  • Polycrystalline

A solar panel made of polycrystalline cells features many small-sized crystals of silicon. Because of the smaller dimension of the silicon wafers, electrons cannot move as efficiently as in a single-crystal silicon. In other words, they are less efficient than monocrystalline solar panels. The good news is that they are less expensive.

  • Amorphous

This type of solar panel is not ideal for vans and RVs. They take up more space and can be quite expensive. The advantage of this type of solar panel is that it works even in cloudy weather.

Advantages And Disadvantages Of Using A Solar Panel For Van

One of the top-rated ways to enjoy the comforts of home in one’s van is by using a solar panel to run the different electrical appliances and gadgets in the vehicle. Like all things, however, there are advantages and disadvantages to such a solution. Understanding what these are can help you decide whether a solar panel for van is right for you or not.


Free Energy

The traditional way of operating AC appliances in a van or RV is by using a generator. This machine requires gas, consuming about 0.5 to 1 gallon of gas per hour. If you were to run the generator for about 5 hours, you will be spending 2.5 to 5 gallons. This can cost you around $7 to $15 for using the generator for only 5 hours.

Using solar panels will not cost you anything, except for the price of the solar panels and the other components of the solar energy system. Suppose you will be spending about $300 for the whole system, this is already equivalent to twenty 5-hour use of a generator. The solar panel system already pays for itself.

Requires Very Little Maintenance

Maintaining a solar panel is easier than maintaining a generator. You only need to wipe clean the surface now and then and check the different connections. Removing dirt and dust from the panels can help the system absorb more sunlight with greater efficiency.

Contributes to a Clean Environment

This is an advantage of all solar power products. You get to contribute to the ongoing movement towards lesser carbon emissions. You also get to ensure a greener and cleaner environment. Of course, there will always be issues of carbon emissions in the manufacture of these products. When you compare it to conventional methods, however, it will still turn out cleaner and with less impact on the environment.


Dependent on the Weather

The main issue about solar panels for vans is that they are very dependent on the weather. There are advanced solar panel technologies that work best in an overcast or cloudy sky. They also do not get affected by snow and severe weather storms. The problems with these technologies are that they are costly and are not suitable for use on vehicles like vans. Those solar panels that are suitable for vans may not function well if the sun is not shining or in low light conditions.

How We Picked And Tested


Choosing a solar panel to use in your vehicle can be confusing. This is especially the case for those who are newbies to the world of solar energy. That is why we came up with a list of the top solar panels to use in your vehicle. Here is how we picked, analyzed, and tested what we believe to be the best solar panels for vans.

  • Solar Panel Efficiency

The principal function of a solar panel is to generate electric current by absorbing sunlight. We recognize the fact that there are solar panels that absorb sunlight a lot more efficiently than others. That is why we had to evaluate the efficiency of the solar panels to make sure that you will get the maximum energy output for your van’s appliances.

We know that high-quality solar panels have an efficiency rating of 20 to 23 percent. Good quality solar panels can have an efficiency of between 15 and 18 percent. This is good enough. As such, we set our parameters to include only solar panels that have at least a 15 percent efficiency rating.

  • Wattage

What is the use of installing a solar panel in your van if it cannot deliver the much-needed energy to power your devices? While the final power output of the solar panel will depend on your intended use, we know that a solar panel with higher wattage will deliver more power to more devices in the vehicle.

We examined the different solar panels and focused more on their power output in terms of voltage. We then took into consideration the size of the panel. We prefer a small solar panel that can produce high voltage over a large solar panel that delivers the same amount of voltage. After all, space is something that our vans do not have plenty of.

  • Ease of Installation

We also investigated the ease of the solar panel’s installation. We included both portable and fixed types of photovoltaic panels in our tests. We made sure that the products are easy enough to install and use. In the case of fixed panels, we only chose those that do not require specialist skills in the installation of the product.

It was also critical to examine the manual that came with the package. We evaluated it for readability. If the instructions are very complicated, then some people may have problems installing the system in their vehicles.

  • Included Accessories

We examined each product for any inclusions. At the very least, it should come with the hardware necessary for its installation. If the manufacturer included cables, blocking diodes, and other essential accessories to set up the solar panel, then we believe that the product is the right choice.

  • Price

One of the reasons why some people have second thoughts about using solar energy power is the high cost of starting a system. That is why we also evaluated the price of the solar panels relative to its other features. We included only those that have a higher intrinsic value relative to its price tag.

Frequently Asked Questions


How many solar panels do I need for a 12V battery?

A single 300W solar panel for camper van units is sufficient to charge a 12V battery. However, the final number depends on the solar panel’s power output and the 12-volt battery’s rated capacity.

For example, suppose you have a 12V 200Ah battery for solar power motorhomes with an 80% discharge depth. In that case, you can only expect the battery to reach 160Ah at most. Let’s assume that the battery takes 2 days to drop to a 20% – this means you consume around 80Ah per day.

We know that a 100-watt solar panel for van roof generates about 30Ah daily. Dividing the battery’s power requirement (80Ah) by the solar panel’s energy output (30Ah) will give us 2.67. Hence, you can have three 100-watt solar panels for caravan units or a single 300-watt solar panel to charge the 200Ah, 12V battery.

How long will a 12V 300W solar panel take to charge a 100Ah battery?

A 12V 300W solar panel needs an average of four to six hours to charge a 12V 100Ah battery. The charging time could be longer in less-than-ideal conditions, such as overcast skies, too much shade, and inclement weather.

How did we arrive at the answer? First, divide the campervan solar panels wattage with their voltage. In this case, 300/12 will be 25 Amps. However, as the van solar systems might not always get optimum sun exposure, they sometimes can only produce around 16 Amps.

Now, to learn the estimated charging time, divide the battery capacity (which in this case is 100Ah) by the panel current we’ve just learned – 16 to 25 amps. This leads us to determine that a 12V 300W solar panel will take 4-6 hours to fully fill a 100Ah battery.

The formula can be summed up as below:
