Why Today's Solar-Powered Generators Are a Better Option for Van Life and RVs

How Is a Solar-Powered Generator Different from A Fuel-Powered One?

A good generator is a vital part of RV and van trips. They’re what keep fridges running and phones charged, so we can understand why people are sometimes hesitant about switching over to a new power solution. 

To put your mind at ease, we’re going to demystify the differences between solar and fuel generators and look at why most of these differences make life in a van or at a campsite easier and cheaper:

• Power Source: While fuel generators burn fuel, such as diesel, to create electricity, solar generators charge up by being connected to solar panels that convert sunlight into power. These generators also include large batteries where that energy can be stored for long periods. As we’ll explore more in this article, the batteries are usually designed to charge not just via solar panels but via your vehicle and wall plugs (AC) as well. This means that solar options have built-in alternatives for charging, unlike diesel generators, which only work with diesel fuel.

• Fuel Availability: The switch from diesel to solar can make things much more convenient in more rural areas where diesel isn’t easy to get. The only fuel you need to worry about for solar generators is UV exposure.Most solar panels can charge up generators even on overcast days, but long periods of bad weather can make things tricky. The upside is that as long as you have a car, all the generators we recommend can still be charged, even when sun exposure is limited.

• Noise Pollution: There is nothing worse than driving out into nature’s most stunning, tranquil areas, only to have your peace disturbed by the rumbling sounds of a diesel generator. In contrast, solar generators are virtually silent. The worst it gets is that they might sound like a loud fan due to the cooling systems. 

• Air Pollution: Fuel-powered generators produce massive emissions. This isn’t great for the planet in general, and it certainly isn’t good for air quality when you’re in protected areas. Solar generators, by contrast, run on clean energy and don’t produce emissions during usage. 

• Maintenance: Solar generators are seriously low maintenance. Unlike the constant oil changes, servicing, and filter cleanings required to keep fuel generators running smoothly, solar solutions usually just require surface cleaning so that the panels can capture sunlight effectively. Many also have in-built temperature and voltage control for added durability.

• Safety: To keep a fuel generator running, you always need fuel on you, which in itself poses safety risks. The potential for ignition is a concern at every point – from when you’re storing fuel, filling the generator with it, and while the machine is running too. Another safety hazard is the toxic fumes these machines release. It means that they can’t be used in tents and generally need to be treated with far more caution than solar alternatives. 

• Set-Up: Solar generators just need light exposure and a bit of airflow so the cooling fans can effectively cool the module – that’s all. Fuel options, however, can only be run in certain zones (usually far enough from people that fumes and noise won’t be disruptive) and involve more complicated, technical setup because of safety related precautions. They also need to be retrofitted into an RV, while solar generators can be plugged in and easily moved around much like your laptop. This provides so much extra flexibility.

• Cost: Even the most affordable solar generator or very small generator for camping will require an investment. In the long term, however, they usually work out cheaper than fuel-powered options. This is because you won’t have to buy fuel constantly or worry about replacing parts. Solar panels tend to be very durable and long-lasting, with most having 5-year warranties and 10-year batteries.

• Portability and Ease: At first glance, it’s easy to assume that solar generators and their accompanying panels are more difficult to get around than fuel generators. We’re happy to say that isn’t the case. Solar generators are lighter, smaller, easier to carry (many have handles and wheels), and much safer to move around than diesel versions because there’s no risk of accidentally spilling or igniting highly flammable fuels.  Solar generators tend to be fairly light considering the energy density they can provide, and the solar panels are quite moderate in weight, are foldable, and are easy to stash in your vehicle or pop out at a campsite. Some even come with convenient bags or handles.

What Is the Best Solar Generator on The Market

The best solar-powered generator does not exist. We say that because each is designed for different contexts. Some are better suited to camping; others are more appropriate for RVs.

Finding the best solar generator for your application is all about properly defining what it is you need your generator to do and then finding one that is able to more or less cover your demands. For example, the basic points to consider are the power output (wattage) and capacity (kWh or kilowatt hours) you need in order to support your camping and RV lifestyle. This alone will help narrow down the options to the ones most suitable to you and your setup. 

To provide more ease, we recommend going with an option that can provide maximum power output and capacity that is at least 10% higher than what your calculated demands are. Obviously, this also depends on whether the unit fits within your budget and space requirements.

In the next section, we’ll discuss all this in far more detail and help you figure out which aspects of a solar generator to prioritize so that you get the best possible match.

On Selecting the Right Solution

Here’s what to consider when trying to decide not just what is the best solar generator for camping or vans but what solution is best for you and how to get there:

• Consider Your Set-Up and Space: This is the most practical place to start. Consider whether your solar generator will be primarily for camping, RV, or home use. If you are living out of your van or RV most of the year, you might want a generator with a higher max power output and longer run time, which means you'll need a higher battery capacity. It's also important to note where you want your generator stored, how you like to set up your area during stops, and the appliances you want to keep powered up. This will impact the number of ports you need and the size of the generator that will be most convenient. Solar generators come in a range of sizes, with some, like the Delta2 Eco-Flow, being super space efficient, while others are a little chunkier. Just know that smaller ones tend to hold less power and that regardless of what you choose, generators require ventilation to work well and last a long time.

• Portability: Check the weight of the generator and if there’s anything about it, such as wheels or handles, that will make it easier to take in and out of your vehicle as needed. Some even have drop-proof technology for extra peace of mind.

• Durability: Check what’s been said about its durability. Is there any warranty on it for repairs? What’s the battery quality like? The best way to judge is to check if the battery has been cycle tested for durability and whether or not any environmental testing has been done to see if it is able to perform and withstand specific climates, being moved around a lot, etc. The same needs to be considered for accompanying solar panels. It’s also worth checking if the generator has any added safety certifications and what long-term customers have said regarding their experiences with the product.

• Battery Type: Not all solar batteries are created equal. The most common ones you’ll find in solar generators are lithium-ion (Lion) or lithium iron phosphate batteries (LFP). The latter tends to have better long-term durability and a wider operating temperature range, meaning that it’s better for cold weather applications. The downside is that the LFP releases more heat than the Lion and needs more ventilation as a result. The Lion is ultimately more energy dense, though.

• Power Output: Check the wattage of your most energy-intensive item (usually something with a heating element like a hairdryer) against the wattage of the generator’s power output to be certain it can support your power needs. There’s nothing worse than setting up for a cool, crisp evening under the stars and finding that your generator cuts every time you try to connect the stove.

• Available Ports: What is the adaptor situation like, and does it suit your appliances? Are there enough ports for what you plan on plugging in? If you have an RV, check that the generator has a proper outlet for it so that you can plug it in directly. Here’s a helpful guide on RV port requirements.

• Charging Frequency: Knowing how long your generator can provide the average power output you require for your setup is crucial for determining the convenience of the power generator in question. If your generator can provide your average power output for only a few hours and has no ability to fast charge through your vehicle, you may need something that has a higher capacity but still keeps the same max power. When choosing the best solution for you, look at how many hours of power the generator will provide when supporting your appliances. Can it provide 4,6, or 8 hours of power for your unique set-up on one charge, or will you need to recharge it frequently?

• Charging Time: Most solar generators will provide a guide on how long recharging takes with different solar panels and power inputs connected. Generally, it’s best to go for a quicker charging time because it means that even if you only have a quick stop or few hours of sun left by the time you land at a campsite, you can still power up easily. A flexible charge rate can also be a bonus, though. This ensures that on days when you’re in a rush, you can get a quick charge via a wall outlet, but on slower days, can let the battery take its time and preserve its overall lifespan.

Brands That Offer Practical and Reliable Solar Generator Set-Ups for Vans and RVs

Finding the best portable solar generator can get a bit overwhelming when you start wading through all the technical specs, etc. We’ve tried to make things easier for you by nailing down some of the best options that will power up your van and RV with ease.

When creating this short list, we:

• Assumed a comfortable coverage of 6-8 hours. 
• Allowed for the availability of a maximum power rate of at least 1500W (hairdryer or fridge) and connection via USB-A and USB-C.
• Made sure you’d be able to connect to the internet the whole time and charge your essentials (phone, laptop, etc.).
• Checked whether or not you could charge the unit by connecting it to your vehicle when the bad weather rolls in (assuming your vehicle has an easily accessible 12V port)
• Kept the noise down. The sound of a bee is about 73 decibels (Db), and all the options listed sit below that.

Ecoflow

When you compare solar generators on the market, one of the things that make this company stand out is that their products are all linked to a mobile app that allows you to check charging, even when you’re on one side of a mountain and your generator is on the other.

Ecoflow’s generators are all sold separately from the solar panels but are compatible with most standard versions.

Delta 2

Not only is the baseline capacity of this solar generator fantastic, but it’s also easily expandable for anyone doing long trips with a van. Users can run two units off one solar panel and even connect to a vehicle for charging via Ecoflow’s 800W Alternator Charger, which charges 8 times faster than comparable options. It’s great for anyone who wants a generator that can charge via the car, even on shorter road trips.

Customers have commented that the fans on the generator can sometimes be quite loud, but the upside is that the cooling function works very well and helps these generators last well. They also come with a 5-year warranty and provide a highly efficient charge.

Conclusion

Switching to a solar generator is one of the best ways to upgrade your RV and van trips. Solar generators are quieter, safer, and, in the long run, far more cost-effective than diesel versions. They’re also easier to use, more lightweight, and won’t stink up your campsite with fumes.

If sun exposure is a concern, remember that all of the generators mentioned can also be charged via the wall, and most work well with car charging too. You get so much flexibility with these devices and a level of durability that diesel generators can’t provide. If you hate having to worry about fuel and keeping your diesel generator working, make hay while the sun shines and give solar a try instead. Most charge up faster than it takes to pack a van, but they’ll last for years.
