How Much Do Rv Solar Panels Cost

How much you spend on solar panels for your RV depends on what you need from your solar system. If you use a lot of electricity, youll need to purchase more equipment, which will raise the overall price of your RV solar system.

You can find RV solar panel kits for as little as $100 or upwards of $1,000. It really depends on your energy needs. When youre just starting out, you can get an RV solar panel starter kit between $200 and $500.

Kits in this range will usually include a charge controller, solar cables, and one or two solar panels, which is a great jumping off point when youre first getting into solar. But, youll probably still need a generator to supplement your usage. Once you gauge how the solar panels are working for you, you may need to buy more panels.

What Is An Rv Solar Panel Kit

An RV solar panel kit usually consists of at least one solar panel, a charge controller, brackets, and wires needed to mount the panel on an RV. Keep in mind that a solar panel kit doesnt include everything you would need to use the sun to power your appliances and accessories. The kit is just a starter setup. You must add batteries to store the suns energy. You also need an inverter to use that energy to run AC-powered appliances.

10 Best Portable Solar Panels for RV 2022

Solar panels are the major component of RV solar systems, but they are not the only ones. RV requires an off-grid solar system installation to power DC and AC loads.

RV solar systems require solar panels, a charge controller, a battery bank, and an inverter. Here you will learn what these components and their functions are:

How Much Power Can Rv Solar Systems Generate

One thing we know about solar energy is that it is unlimited. Theoretically, you can expect your solar for RV to generate infinite power if you have the correct solar system setup and the ideal environmental conditions.

Unfortunately, nothing is ideal or infinite. You cannot expect the sun to shine over your RVs solar panels continuously 24/7. There will always be cloudy or rainy days and nights where the solar system cannot produce energy for your RV appliances.

Solar technology also has its limitations. For example, the most efficient solar panel can only produce 415 watts. Most RV solar panels on the market can generate about half that. Hence, you can install ten 200-watt solar panels to generate about two kilowatts.

It should be sufficient for most RV appliances, but not the power-hungry ones, such as water heaters and air conditioners. You can still run these appliances, but only for a few hours, not for extended periods.

Unfortunately, your RVs roof is not as extensive as your houses cover. Some RVers can only install six to eight solar panels, severely limiting their RV solar systems power generating capabilities.

Do You Really Need Rv Solar Panels

While RV solar panels are great, they arent necessary. In fact, most RV campers probably dont need solar panels – if you spend most of your time camping on campgrounds with power hookups, then RV solar panels probably arent right for you.

But, for all of the boondockers out there, RV solar panels are a great, cost-effective investment. Boondocking is when you camp off-grid, outside the amenities of campgrounds, including electricity. In this case, RV solar panels can come in handy. They allow you to keep your batteries charged, and you can charge additional batteries for backup power, as well.

Also, because the solar panels slowly charge your batteries, they can end up prolonging your RV battery life. Plus, unlike conventional generators that you may use to help power your RV, you dont have to worry about buying propane for every trip. Once you invest in RV solar panels, there are almost no additional operating costs unless equipment needs to be replaced.

How To Estimate Your Wattage Demand

If you want to only pay for what you need and be precise with estimating the wattage rating your solar system should have, you will need to calculate your average daily power consumption.

Charging House Battery

For instance, you only need a small solar system to top off your deep cycle house battery. Lets say your 12 volt battery bank has a capacity of 200AH this rating means this battery can supply 200 amp-hour of power per day during a period of 20 hours, which is the standard available use. Divide 200 amp-hour by 20 hours, we get the amp rating of the battery, which is 10 amps.

This battery must be charged at 10 amps and 12 volts, which means if you intend to recharge this battery with solar panels, your system must be capable of at least: 10 amps x 12 volts = 120 watts of power.

When it comes to your precious house battery, always go up to the next common size to stay on the safe side. This means you need at least two 100-watt solar panels to get a total capacity of 200 watts.

Wattage Demands of Motor-Driven Electronics

Otherwise, you may need to power a number of electrical appliances. To estimate your average daily power consumption, you will need to add up the starting wattage of all the electronics that you often use, which can be found on their nameplate.

Solar panels for homes have become more increasingly a common occurrence. With different financial incentives getting passed to entice homeowners to purchase solar panels its no wonder that those that have solar panels installed on their homes roofs could also thing to installing solar panels on their motor homes. A good RV camper offers the serenity of nature along with the basic comforts and conveniences of the modern world. To make your travels more eco-worthy, investing in one of the best solar panels for RV use is a obvious answer to staying connected off-the grid.

Gas generators are fairly common in the RV world, but they tend to be noisy and can disrupt your outdoor idyll. A better option is to embrace the clean, renewable energy of the sun Invest in solar panels to keep everything in your RV humming along.

Run Wiring To Battery Bank

Once your panels are securely in place, its time to run wiring down into the RV and to your battery bank.

Three places that are commonly used to run wires down into the body of the RV are the refrigerator vent, a plumbing pipe, or simply by drilling a new hole in your desired location.

With all approaches, make sure you take appropriate steps to weatherproof all areas where changes have been made once wiring is run.

Calculating Energy Generation And Storage Needs

A decent assumption is that a 100-Watt solar panel will generate on average 350 Watt-hours of power per day. However, this will vary significantly by location and time of year. This article by Mortons on the Move explains a way to get a more accurate result by using PVwatts.

Youll also need to know how many batteries youll need to store that amount of power! One 100 ah 12volt Battle Born battery has about 1200 Watt-hours storage capacity.

Keep in mind that your solar panels will only give you the stated number of Watts under perfect conditions. Perfect conditions = direct sun pointing directly at the panel. On a rainy day, you wont get 100 Watts from your 100-Watt solar panel. If youre parking in the shade, you wont get 200 Watts from your 200-Watt solar panel.

Its also challenging to estimate the amount of power youll use on a given day because days are different. You may be outside all day today enjoying nature, and fall into bed and watch 15 minutes of television tonight. Tomorrow could be a rainy day, and youll stay inside your RV, do a lot of work on your laptop, and watch a couple of hours of television in the evening. So estimating high is usually a good idea!

Using Lead Acid Batteries

RV Rooftop Solar Kit, 300W, Dual Panel

Heres why you dont want to use lead-acid batteries for everyday solar applications: Solar systems are collecting power and transferring it to your batteries every time the sun is out. In other words, you are charging and depleting your batteries almost constantly.

Because lead-acid batteries can only safely be discharged to 50% before they are damaged, you are using their limited charge cycles several times and shortening the batterys life much quicker.

Also, lead-acid batteries take much longer than other battery types to recharge. Power to your devices is not available as quickly if you are totally dependent upon solar for your energy needs. Using lithium or even AGM batteries will give you quicker charge times and lower discharge rates and will require virtually no maintenance on your part.

Not Using Fuses And Breakers Properly

When solar energy is added to the mix, there are several parts to the system that should have stop-gaps. This will help protect your appliances on the electrical line. Three places in particular should have fuses to do that, and if they are not installed properly or are undersized, they will not be able to do the job correctly, leaving your solar system and your coach jeopardized.

Make sure an inline fuse is placed between the solar panels and the charge controller, another one placed between the charge controller and the battery bank, and a third-placed between the battery bank and the inverter.

What Other Components Do You Need For An Rv Solar Panel System

There are other components youll need for your RV solar panel system. So far, youve figured out how many RV solar panels you need and decided what type of panel you want. Getting the energy to the house batteries requires additional equipment.

You need somewhere to store electricity and something to control charging . And if you want to power 120v AC devices, youll also need an inverter.

Do It Yourself : And, in fact, if you are a DIYer, doing the installation yourself is definitely possible. Just make sure you consult with an expert to ensure everything is properly positioned and fixed.

Safety is a high priority. Because you dont want any fires or medical emergencies to spoil your fun on a remote camping trip, where people and resources are limited.

After all, an RV goes hand in hand with relaxation and getting away from all the hustle and bustle of everyday life.

Get an Expert : So to keep with that theme, do it yourself, or if it is too technical for you, employ an expert to reap the best benefit from it and also to get it right the first time around.

How Many Rv Solar Panels Do You Need

Better Way to Mount Flexible Solar Panels on RV (2019)

Unlike residential and commercial solar systems, which are designed to power an entire home or business, RV solar systems typically deliver a more modest output. This usually isn’t an issue since you don’t use as many lights and appliances in your RV as you would in a brick-and-mortar property.

So how many solar panels will you need for an RV? It depends on a few factors, including your energy consumption habits, the efficiency of the panels and the amount of sunshine your home receives each day.

Calculating your average daily energy consumption is the first step to determining what size RV solar system you need. To do this, you’ll need to make a list of the appliances you want to use, how much power they require and how many hours per day you’ll use them.

For example, let’s say you have a 500-watt microwave that you want to use for 15 minutes each day. By multiplying these figures, you can determine that you’d need to generate 125 watts of electricity just to use your microwave for that amount of time. Repeat this process with every device or appliance.

To figure out how much electricity your system will generate per day, you need to multiply your system size by how many hours of direct sunlight your panels would receive daily.

With some quick math, we can see that this system will generate 4,000 watt-hours of electricity per day. You can use this output as a benchmark to compare against your energy needs , then adjust the number of panels and wattage accordingly.

Solar Power And Sustainability In Campgrounds

A representative from Nuance Energy, a company that specializes in solar products and services, mentioned, RV parks are often ideal sites for solar energy for two reasons: They have a large footprint and, as the equivalent of little towns, they consume a lot of electricity. RVers also tend to like the idea of conserving energy and getting it from renewable sources, making a park with solar energy production all the more appealing as a place to stay for a while.

RV parks and campgrounds that have embraced solar power have not only lowered their carbon footprint. They have also brought a new experience to the camper. The new Panelview RV Park in Hermiston, Oregon has an interesting set-up. Each RV site has a 3kW solar panel mounted on a pole. The panel provides shade for the RV. Plus, on a sunny day, more energy can be produced than a motorhome can use.

Tucson/Lazydays KOA Resort in Arizona has solar structures that shelter 30 RV sites.

We have a massive Solar Parasol structure that covers two acres of RV sites at our Tucson/Lazydays KOA Resort in Arizona,KOA president and CEO Toby ORourke said. That structure supplies more than enough power for the campground while providing partial cooling shade for the RVs parked beneath it.

With so many advantages to the campground and campers , we may see even more RV parks jump on the solar power train.
