Going Off Grid: Tips for RV Solar Panels
Whether you’re going off grid in the backcountry or just want to cut back on campground hookups, RV solar panels offer a greener, more adventurous way to hit the road.
Of course, diving into the world of solar panels can feel a bit overwhelming at first. Do you go for good solar panels that fit your budget, or splurge on the top-tier options? What are the actual benefits of RV solar panels, and how do you get started without feeling overwhelmed? Don’t worry, we’ve got you covered.
With so many options out there, from choosing the best solar panels for RVs to deciding on installation methods, it’s easy to get stuck in research mode. But we have a few tips that will help get you started.
You Should Know:
Before you dive in to your solar journey, make sure you’ve considered the following factors:
- What is your RV lifestyle? Are you the type of adventurer who’s going off grid for extended periods of time, or do you prefer the comforts of campgrounds with hookups? Your adventure style will help determine how much solar power you really need.
- What are your energy needs? Are you aiming to power everything in your RV, or just looking to charge your phone and power a couple of small things?
- How much space do you have? Got enough roof space to fit those panels? Make sure your RV roof has room for solar, and if you’re going portable, check you’ve got space to stow them away.
- What is your budget? Costs for RV solar systems vary based on your setup so starting with a clear budget in mind can help guide your decision making.
1. What Type of Solar System Should I Get For My RV?
If you’re just starting, portable or small roof-mounted systems let you dip your toes into RV solar energy without a huge investment. However, if you’re ready to commit to off-grid RV living and know your energy needs, investing in a comprehensive roof-mounted system from the beginning can save time, money, and effort in the long run.
Types of RV Solar Systems:
- Portable Solar Panels: Great for beginners or weekend campers, these are lightweight and easy to set up. You can move them to follow the sun and pack them away when not in use. Ideal for those who want flexibility or aren’t ready for a full installation.
- Permanent Solar Panels: Perfect for long-term use and off-grid RV living, these are permanently installed on your RV roof. They provide a consistent power source without taking up storage space but require proper planning for placement and wiring. This option is will also be a bigger investment compared to portable options but can be scaled to fit your energy needs.
2. What Components Are Included In A Full RV Solar Power System?
A typical RV solar power system includes solar panels, a charge controller, batteries, and an inverter. The solar panels capture sunlight and convert it to electricity, which the charge controller regulates to ensure your batteries aren’t overcharged. The batteries store the electricity for later use, and the inverter converts the stored power into power that your RV can use.
3. What’s The Difference Between Flat and Curved Solar Panels?
There are a few differences between flat and curved solar panels aside from their shape. Curved panels are more aerodynamic for the road, but they can’t be tilted to face the sunniest spots because they curve smoothly around your rig’s body. Curved panels are generally lighter, while flat panels are more durable and can be more easily adjusted to the sun. Essentially, it comes down to budget (Spoiler alert: curved panels tend to be the more expensive option).
4. Can I Use Solar Panels When I’m Driving?
Yes, RV solar panels can generate power while you’re on the road, provided they’re securely installed. As long as your panels are properly mounted and wiring is safely tucked away, you can take advantage of sunlight even when you’re not parked.
5. Can I Use RV Solar Power In Cloudy Weather?
Yes! Solar panels will still generate some power on cloudy days, though their efficiency will be lower. If you’re in a region with frequent overcast skies, you might need a larger solar setup to compensate for the reduced sunlight.
6. Can Solar Panels Fully Power My Unit For Off Grid RVing?
The short answer is, yes! However, the feasibility depends on factors like your RV’s energy consumption, the size of your solar system, and your battery storage capacity.
7. Can I Use RV Solar Power to Run Air Conditioning?
Running an air conditioner off solar power is possible, but it requires a hefty solar setup. You’ll need a large solar array, a powerful inverter, and a substantial battery bank to power an AC unit for extended periods. It’s not ideal for every setup, especially if you’re only using a small system.
8. How Long Do Solar Panels Last?
RV solar panels are built to last and their lifespan continues to increase as technology progresses. Our recommendation? Invest in good quality solar panels and if they’re well-maintained, you’ll be reaping the benefits of solar power for decades. Over time, they may lose a small amount of efficiency, but high-quality panels can still provide reliable power for over 25 years or more.
9. Do RV Solar Power Systems Require Regular Maintenance?
Maintaining your RV solar system is relatively simple. Clean your panels regularly, check your battery levels, and ensure all connections are secure and free from corrosion. Also, check the health of your battery bank periodically to ensure it’s holding a charge.
10. Can I Use Solar Power And Plug Into Campsite Hookups At The Same Time?
Yes, you can absolutely use shore power (electricity supplied at your campsite) in tandem with solar power.
When you’re connected to shore power, it can supplement or even replace the need for solar energy, especially if you’re running high-power appliances like air conditioning. You can seamlessly switch between solar and shore power as needed. Most modern RVs with solar systems have an automatic transfer switch or a power management system that allows you to use both energy sources without any manual intervention.
10. Can I Install My RV Solar Power System By Myself?
While installing your own RV solar power system might sound tempting, it’s not exactly a plug-and-play project. There’s a lot of wiring, safety checks, and technical know-how involved—so unless you’re already an electrician, it’s usually best to leave the installation to the pros. That way, you can kick back and enjoy the sunshine, knowing your system is set up safely and efficiently!
With a little research, some planning, and maybe a little help from the pros, you’ll be well on your way to harnessing the sun’s energy. So, get ready to hit the road, enjoy those sunny days, and feel good about your greener, more independent RV lifestyle.
