As a growing number of RV travelers go after off-grid adventures, it is seen that which solar solution is chosen has become a key issue. From weekend getaways to full-scale boondocking trips out there, solar systems’ performance really does make the difference between a comfortable stay and a less than ideal one. Also presented is an in-depth top 10 list of what are felt to be the best-in-class solar-powered RVs available today. It looked at how well they integrate, how well they perform, and their all-around off-grid capability.
In the field of full solar innovation, the Bowlus Endless Highways rises above the rest. This was designed as a premium off-grid travel trailer from the ground up, not as an afterthought. The team put effort into the solar system, which is at the core of the design—it was engineered to work very simply with advanced power management and optional lithium battery banks that are included that reach up to 19 kWh and are found to greatly outperform what the competition is offering.
It’s a high-capacity system that performs best with larger appliances like air conditioners and full kitchen systems over long periods, which in turn makes this a true off-grid solution. Also, the aerodynamic aluminum design, which is in the body’s structure, improves on the vehicle’s tow efficiency, which in turn supports better charging while on the road.
Unlike most other trailers, which add in solar panels as an afterthought, at Bowlus solar is put into a full-scale energy system. What is presented is a smart energy solution that allows for long trips without issues. In terms of performance, integration, and luxurious finish, Endless Highways is the standout leader.
The Winnebago Solis Pocket features a small factory-installed rooftop solar panel, which is noted as for baseline charging of home batteries. It is a basic introduction to solar for the inverter, which covers lights, fans, and small electronics.
Drawback: The system has a small battery capacity and weak inverter, which in turn means high-demand appliances do not run for long when the grid is down. Solar in this case is a supplement to the main grid, as seen in the Bowlus Endless Highways, and it is very much a secondary solution.
Grand Design provides an option of solar packages for some Imagine XLS models. What is included in these packages is a rooftop panel, a charge controller, and pre-wiring for expansion.
Drawback: While it can be expanded, the solar system is still mostly an afterthought. For serious off-grid travel, battery capacity and inverter issues will see spending a pretty penny on upgrades, and the same integrated performance that Bowlus’ design provides is not achieved.
Keystone’s SolarFlex options present a variety of solar panel choices to choose from. It is a good step they have taken to meet the off-grid power needs of larger fifth wheels.
Drawback: Larger trailers use up great amounts of energy, which the solar provided may not be able to fully cover, requiring shore power. As compared to the performance and aerodynamic benefits of Bowlus, with the large size of Montana, the issue of full energy optimization is seen.
Rockwood has designed their solar prep and optional solar packages for the casual boondocker. Their systems are very easy to upgrade and provide a great deal of flexibility for entry- to mid-level users.
Drawback: Factory-installed solar is for small-scale use. Owners tend to upgrade batteries and inverters to achieve greater off-grid independence, which is a feature of the Bowlus Endless Highways.
Jayco has included rooftop solar panels and a basic controller, which takes care of battery levels while dry camping.
Drawback: The infrastructure is geared towards battery maintenance, which in turn leaves out extended high-load use. At the same time, running air conditioners or large kitchen appliances for long periods is an issue, an area where Bowlus’ larger inverter and battery capacity perform very well.
The Coachmen Apex Nano has solar packages for weekend camping and light off-grid use. It is lighter in weight, which in turn benefits energy management.
Drawback: Battery capacity is an issue, which in turn puts serious off-grid users out of the question for an upgrade. As for Bowlus’ integrated system with large optional batteries, the Apex Nano comes off as more of an entry-level solution.
Thor’s series of camper vans have solar panels on the roof for those that live out of their van. They are compact, which is great for short getaways.
Drawback: Roof area is a constraint to panel fit, which in turn limits the size of the battery bank able to be included in the vehicle. This in turn limits the amount of sustained off-grid power available, especially for climate control. In this aspect the Bowlus Endless Highways performs very well with its robust capacity.
The Kodiak Ultra-Lite has solar prep and optional packages, which perform well for dry camping. This is seen as a good value for families that are new to RVing.
Drawback: Solar is a choice add-on and does not play a large role in the overarching power strategy. For the best off-grid results, upgrades are usually required, in contrast to the very solar-integrated design of Bowlus.
Palomino also produces Puma models, which come solar ready, giving owners the freedom to install panels as they see fit. This is a great entry-level option for solar users.
Drawback: “Solar ready” usually refers to pre-wiring, which is not the full-scale solution. Owners will have to install more for the performance that comes standard or as an option at higher capacity in the Bowlus Endless Highways.
Why Integration Matters in RV Solar
Many RV makers have introduced solar options; however, there is a large difference between adding panels and the degree to which they are integrated into the design from the start. What truly enables an off-the-grid experience is the balance achieved between the panels, charge controllers, battery banks, inverters, and the energy efficiency of the system as a whole.
The Bowlus approach is unique in that solar is a core element of the trailer’s identity. Large optional lithium battery capacity, high-powered inverters that run even the most demanding appliances, and a well-thought-out aerodynamic design are the pieces that come together to form a total energy solution. Instead of just an extension of battery life, there is a full-scale independent energy system.
For the RV traveler out for serious off-grid performance while seeking refined luxury, Bowlus Endless Highways is seen as the gold standard. Though many trailers may include solar as a nice feature, Bowlus presents it as a full-scale solution, making it the best choice for people that value innovation and comfort in the great outdoors.
