Switching to RV solar is a game-changer for anyone who wants more freedom and flexibility on the road. Whether you're a weekend warrior or a full-time RVer, solar power gives you the ability to boondock longer, save on campground fees, and live a more sustainable lifestyle. But let’s be honest: it’s not always plug-and-play.
We’ve seen too many RVers make the same mistakes when it comes to going solar. So let’s talk about the top five missteps and how you can steer clear of them.
Why RV Solar Mistakes Happen
Installing an RV solar system can be complicated. There’s a lot to consider — panel type, wattage, battery capacity, charge controllers, and more. Many first-time users either overestimate or underestimate what they need, which can lead to frustration (and a dead battery in the middle of nowhere).
Let’s break down the most common mistakes and how to avoid them.
The Top 5 Mistakes RVers Make with RV Solar
1). Underestimating Power Usage
This is the big one. Many RVers don’t take the time to calculate how much energy they actually use. Running a fridge, lights, fans, and especially things like microwaves or air conditioners adds up fast. If your solar system isn’t sized to meet your daily needs, you’ll find yourself running out of power.
Fix: Take an inventory of your appliances and devices, and figure out your average daily power usage in amp hours. Use that number to size your solar system appropriately.
2). Using the Wrong Type of Battery
Not all batteries are created equal. Flooded lead-acid batteries, AGM, and lithium batteries all behave differently — and some play nicer with solar than others. Choosing the wrong battery can limit how effectively your solar system stores and delivers power.
Fix: If budget allows, go with lithium batteries. They’re lightweight, long-lasting, and more efficient when paired with RV solar systems.
3). Poor Panel Placement or Shading
Solar panels need direct sunlight to do their job. Even partial shading from trees, roof vents, or A/C units can sometimes reduce their output. Many RVers install their panels once and forget about them, not realizing they’re missing out on potential energy.
Fix: When possible, park in open areas with full sun exposure. If you're using portable panels, move them throughout the day to track the sun.
4). Neglecting Regular Maintenance
Dust, pollen, and bird droppings can block sunlight and cut down your solar efficiency. Many people forget that RV solar panels need cleaning and occasional inspection to keep working at their best.
Fix: Clean your panels regularly with water and a soft cloth or sponge. Check for loose wires or cracked glass, especially after long trips or rough weather.
5). Expecting Solar to Power Everything
RV solar is amazing, but it has limits. Unless you’ve invested in a large system with lots of storage, it’s not going to power your air conditioner or microwave for hours at a time.
Fix: Manage your expectations. Use solar to power essentials and conserve energy when needed. You can always add more panels or batteries later if you want to upgrade your setup.
