How to Choose the Best RV Solar Panel Kit
The best RV solar panel installation depends on your vehicle, your energy needs and what hardware and power you already have in your RV. In order to make an informed decision, pay attention to the following key characteristics.
- Solar Panels
- Charge Controller
- Power Inverter
- Power consumption
- Best RV Solar Panel Brands
Motorhome solar panels allow you to capture energy from sunlight. With higher-grade cells, you’ll get more efficiency and therefore more output, even on days where sunlight is less than ideal.
Panels typically operate around a 15% efficiency rating, but advanced models push that beyond 20%. Solar cells are constructed from silicon, with purity and construction influencing the output rate.
Monocrystalline Panels: Use purified silicon and are more effective and more costly.
Polycrystalline Panels: Panels have a less pure crystalline structure, which reduces cost but also efficiency.
If sunlight hours are limited for you, choose a high-grade panel. Also consider the mounting space available and if you will want to upgrade your installation in the future.
Chances are, solar panels will fight for space with other hardware on your RV roof, such as an antenna or air conditioner, so plan wisely. The lightest panel is the Allpower SunPower panel, which is also flexible.
Solar panels don’t produce energy at a steady rate, so you need a charge controller as an interface to your batteries.
This device prevents both batteries as well as panels from damage an regulates the charge according to the battery’s state. All kits we’ve reviewed that come with a controller use a form of smart charging called Pulse Width Modulation (PWM).
This type of controller automatically regulates the speed and width of the pulses. The result is that depleted batteries get charged quickly. For the last bit, the controller will switch to fully top of the battery and effectively maintain charge level.
RV solar kit charge controllers also serve to provide a readout and allow you to manually adjust settings.
If you don’t have a deep cycle battery in your RV already and want to use solar power, you’ll need one. That way you can store the generated power for later use.
Solar panels can work with 12V or 24V batteries.
A motorhome typically has a 12V battery or two 6V batteries wired in series. Capacity is measured in Ampere hours. A 100Ah battery can provide 100A for one hour, or 1A for 100 hours.
However, no battery should be fully discharged as it can cause permanent damage. So in an ideal installation, your solar panels can provide enough energy to recharge your batteries to keep them above the maximum discharge percentage.
If you keep using more energy than your solar panels provide, you will ultimately deplete your batteries unless you can add shore power or a generator to keep them level.
The 3 Different Types of RV Deep Cycle Batteries:
Flood/Wet Batteries: These can provide high peak draw and withstand deeper discharge cycles, but are prone to corrosion and therefore require maintenance. They need to be cycled often. A flood cell battery contains lead plates in battery acid.
Gel Batteries: Instead of a liquid, these use a silica gel between plates. Gel batteries are more difficult to charge and therefore not compatible with all charge controllers. They are more expensive and don’t perform so well in a rapid discharge situation.
AGM Batteries: AGM is short for absorbed gas mat. These batteries feature a glass plate inside and are not prone to spillage. They can be used in many situations and are a preferred option for RV deep cycle batteries. They withstand rapid discharge down to around 60% and can be brought back up quickly.
Energy stored in your 12V batteries is only accessible as direct current (DC). Most of the devices and appliances you want to use run on 110V AC (alternating current).
A power inverter is the converter you need. They are rated in Watt: a 1500W inverter is sufficient to operate smaller appliances around 10A AC current, such as a TV, a coffee maker, a laptop, lamps etc.
It can be confusing to calculate how much power you need and how long you can run which device. Remember the basics: the capacity of your batteries (measured in Ah) determines how much power you’ll have stored.
The output of your solar panels will tell you how quickly you can recharge these batteries from the sun. The capacity of your power inverter (measured in W) does not need to match you panels but should be adequate for your batteries and your power consumption.
FAQs About RV Solar Panels
Q: How do I calculate how much energy I need?
A: Power is physics and math. To keep things basic, we’ll use these definitions:
- Watt is electric power = (Amperes x Volts)
- Volt or voltage is electric potential or electric potential difference (Watt divided by Ampere)
- Ampere is electric current (Watt divided by voltage)
In electricity, Watt doesn’t need to be converted between currents, but when changing from AC to DC or the other way round, you need to convert. To convert AC Ampere to DC, you multiply by ten: 10A AC is 100A DC. To convert DC Ampere to AC, divide by ten. 100A DC is 10A AC.
Let’s say you have a TV which runs at 110V AC and is rated 90W. This tell us that it draws about 0.81A AC. Converted to DC current, that’s 8.1A DC.
Watching TV for one hour would consume 8.1Ah – on a 100Ah battery, you could watch about 12 hours before the battery would be depleted.
If you factor in that you should not deplete your battery more than 60% and therefore only 40% of the 100Ah are available, that time gets reduced to a little less than 5 hours.
When you go over the appliances and devices, their power and how much Ampere they draw while considering how long want to use them each day, you can draw up a plan of how much power you’ll consume.
You should match the size of your battery bank accordingly. As an example: you’ll be drawing 120Ah per day and have a 400Ah battery. You solar panels can deliver 160Ah per day, depending on conditions.
As long as there is sufficient sunlight, you’ll be able to charge back up what you use.
Q: Do I have to install a battery?
A: If you don’t have a power bank or battery in your RV or motorhome yet, you’ll need one to store the energy your solar panels deliver.
Solar energy is not reliable and steady enough to simply hook up your appliances directly to the panels as you’ll experience outages. A battery ensures you can draw electricity at night.
Q: What type of panel is most efficient?
A: Monocrystalline panels are more efficient than polycrystalline panels, yet they are more costly. In your installation, you also have to pay attention to the charge controller so it doesn’t become a bottleneck.
With four panels and a maximum of 5A each, your charge controller needs to be able to handle the combined output, i.e. 20A, otherwise you’re wasting energy.
This is why charge controller will specify a limit as to how many solar panels you can add to an installation.
Q: Do I require additional hardware?
A: That depends on what you have already installed in your RV and which solar kit you choose. In our selection, we’ve specified what exactly is included and what you’ll need.
If you’re new to solar power and off-grid electricity, a complete set might be best for you. If you already have batteries and a power inverter, a smaller set or just panels will be enough.
Additional hardware required could also be a switching kit to make it easier to go back and forth between shore and solar power.
Q: What does a typical installation include?
A: To harness solar power, a typical installation includes solar panels which you’ll mount on the roof of your RV, a charge controller which handles the output, a battery or power bank to store the energy
You will also need a power inverter to allow you to run AC appliances of the DC battery current.
Q: Can I run an air conditioner with solar power?
A: You cannot hook up an RV air conditioner directly to solar panels. Air conditioners typically have a power of around 2000W and draw a lot of current and even more when being powered on.
You’d need a high-performance power inverter of at least 3000W and more surge power to run an air conditioner off a DC battery.
How to Install an RV Solar Kit
Powering your RV with solar panels and batteries allows you off-grid freedom and independence. It’s a quiet, low maintenance power source that doesn’t require any fuel.
It’s nearly ideal if you’re traveling in sunny climates and have an existing battery bank or want to install one. Installation is fairly easy and straightforward, and the only drawbacks are the initial setup cost and the fact that output depends on the weather.
