What are RV solar panels and how do they work?
Although they may power lights and small appliances, the batteries found inside RVs are short-lived. You will want an additional power source if you wish to utilize appliances like your microwave and TV. RV solar panels can help with that.
Similar to a typical residential solar system, an RV’s solar panels turn sunshine into electricity. With the exception that they recharge your RV’s batteries rather than powering your home.
Additionally, you can purchase additional batteries that the solar panels can recharge, giving you access to even more electricity while you’re camping.
Four key parts make up an RV solar panel system:
- Solar panels to convert sunlight into electricity
- A charge controller to prevent your battery from overcharging
- An inverter to convert the DC solar electricity into usable AC power
- A battery to store the electricity
Do you really need RV solar panels?
RV solar panels are excellent, but they are not required. In fact, the majority of RV campers likely don’t require solar panels; if you spend the most of your time camping in areas with power hookups, RV solar panels are generally not for you.
But for everyone who boondocks, RV solar panels are a fantastic, economical purchase. Boondocking is camping without power or other amenities found in campgrounds. RV solar panels can be useful in this situation. You can use them to maintain the charge on your batteries and to charge additional batteries for backup power.
Furthermore, since the solar panels slowly recharge your batteries, they may wind up extending the lifespan of your RV batteries. Additionally, you don’t need to worry about purchasing propane for every trip, unlike conventional generators that you can use to assist power your RV. There are almost no further operational costs after making an investment in RV solar panels, unless equipment needs to be changed.
How much do RV solar panels cost?
What you require from your solar system will determine how much you spend on RV solar panels. You’ll need to buy more equipment if you use a lot of electricity, which will increase the overall cost of your RV solar system.
RV solar panel kits range in price from $100 to more than $1,000. Your specific energy needs will determine this. An RV solar panel starter package costs between $200 and $500 if you’re just getting started.
When you first start using solar, a kit in this price range—which often includes a charge controller, solar cables, and one or two solar panels—is a terrific place to start. But to supplement your usage, you’ll probably still need a generator. You might need to purchase extra panels once you assess how well the solar panels are serving your needs.
What to consider when buying RV solar panels
There are a few key things to keep in mind when looking to buy solar panels for your RVs.
Your power consumption
Determine how much power you use while camping in order to determine which solar panels will work best for your RV. You may calculate the number of solar panels and any additional batteries you would require based on that.
The average RV camper uses 20 kWh of electricity each day. You will require more solar panels as a result of your increased electricity consumption as more appliances are added to your home.
However, two or three solar panels will typically be able to provide enough energy to power the majority of your small appliances. You’ll need a generator or more panels and batteries if you want to run heavy equipment like a refrigerator or air conditioner.
It’s okay if you don’t know the exact amount of power your RV consumes. You can always buy a cheap RV solar kit and test it out to see if it works for you. The system can then be expanded if additional panels or batteries are required.
System setup
When you get solar panels for your RV, you can use them one of two ways:
- Manually set up portable solar panels
- Mount the panels on your roof
The majority of boondockers find manual setup to be rather simple. Your solar panels need only be set up, connected to your battery, and pointed toward the sun. Then, to boost solar output, just turn the panels toward the sun every couple of hours. However, keep in mind that you must set it up and take it down every time you visit a site.
If you don’t want to set up portable solar panels, another choice is roof-mounted RV solar panels. However, because the roof needs to be exposed to sunshine, you won’t be able to park your RV in the shadow. In order to gain a little additional juice, you also won’t be able to turn the panels toward the sun. Although roof-mounted systems could cost a little more, full-time boondockers may find that they are more convenient.
Type of solar panels
Solar panels come in three primary varieties: monocrystalline, polycrystalline, and amorphous. The most effective and costly materials are monocrystalline. Monocrystalline panels are unquestionably the ones for you if your space is restricted. Although slightly more expensive than monocrystalline panels, polycrystalline panels are marginally less effective.
Flexible thin-film solar panels are known as amorphous solar panels. They are the least expensive alternative, but they are also the least effective. In order to create anything like to what monocrystalline or polycrystalline panels produce, you would need more of them. Additionally, they must be glued directly onto the top of your RV in order to be fitted, which might damage the roof and make removal challenging.
Batteries
To store your solar energy if your RV has solar panels, you should probably get some extra battery banks. The majority of RVers select 12v batteries. For your RV, you can choose between lead acid and lithium-ion batteries, but each has advantages and disadvantages of its own.
The most typical type of battery used by RV campers is a lead acid battery. They are so well-liked because they are affordable and strong. However, they often need to be changed after five years, and based on the kind of lead acid battery you use, it can need routine upkeep.
Lead acid batteries are significantly less expensive than lithium-ion batteries. They are more effective, endure longer, and store more energy. Lithium ion batteries are pricey, but they’re well worth it for folks that boondock full-time.
However, you can get away with a few lead acid batteries if you only use the batteries for a few excursions per year.
