Best RV Solar Panels – Buyer’s Guide
Having a solar panel system can come in handy especially when you are on the move. It provides the necessary power to run your appliances. This means that you can still have fresh foods, access your gadgets, and lighting even when in the middle of nowhere. The problem, however, is choosing the best RV solar panels for your needs. To help make it easier for you, here are a few things to keep in mind when shopping for a suitable solar panel.
Understand the Panel
A working knowledge of the different types of solar panels that exist in the market is a good starting point in your journey to selecting a suitable solar panel. All solar panels are similar in that they all use silicon as the primary raw material. What differs is the construction and purity. There are four categories of solar panels available on the market today.
First, we have the monocrystalline panels. These panels use the purest available silicon. They are costlier than their polycrystalline counterparts but are also more energy efficient and outperform the latter in shaded or poorly lit conditions. Polycrystalline panels are made from less pure silicon and are not as energy efficient. However, they are the most preferred due to their low cost.
Thirdly, we have thin film panels. These make use of small amounts of silicon infused in substrate surfaces. The result is a pocket-friendly solar panel that has a reduced energy efficiency of about 7-8%. Lastly, we have the Copper Indium Gallium Selenide (CIGS in short) solar panels. This is a variant of the thin film panels that is about 2-5% more energy efficient and has reduced cadmium levels.
The Ideal solar panel for use on your RV should be one that has high energy efficiency, easy to handle and install and light in weight. It is important to note that a few tradeoffs will be expected to be made as all these characteristics are rarely found in one solar panel package.
Know About the Charge Controller
The primary purpose of a charge controller is to regulate the power that reaches the battery to improve its longevity. Charge controllers come in different forms depending on their functionality. First, we have the single phase controllers. These are single output chargers that often operate at high voltages. They are, therefore, useful in supplying a high amount of power over a short period.
Next, we have the single phase trickle controllers. Unlike the single-phase controllers, the trickle controllers operate at lower voltages. While the former is excellent when it comes to reviving a dead battery the latter is effective at bringing it to full charge. Lastly, we have multi-phase controllers. These take the strengths of both the single phase and the single-phase controllers and package them as one. They can switch between high and low voltage outputs depending on the battery’s needs.
The Importance of Battery
The purpose of the battery is to store power. The typical RV system battery is six-volt requiring you to have two of these to match the system’s 12volts. The output of the battery is measured in Amp-hours (amperes per hour). There are three types of batteries – flood cell or wet batteries, gel batteries or absorbed gas mat (AGM) batteries.
The wet batteries consist of lead plates and battery acid. Their strength lies in the ability to maintain more in-depth charging cycles as well as providing higher pea amp draw. The downside is that they are susceptible to corrosion and are cumbersome to manage. Gel batteries, on the other hand, make use of silica gel to store power. They are, however, charger controller specific as well as inverter specific. While there are low chances of spills with these batteries, they are less suitable for rapid discharge and are much costlier than AGM batteries.
AGM batteries make use of a glass plate rather than lead. They are easy to charge, as long as the charger is of good quality, can maintain deep cycling and have a better rapid discharge.
Know About Inverters
The purpose of an inverter is to transform direct current (DC) energy into alternating current (AC). A good number of gadgets and home appliances make use of AC power. The efficiency of the inverter is measured in watts. When searching for a solar panel, be sure to check if the inverter is the right one based on the size of the battery bank. The purpose of doing so is to keep from depleting your battery bank much faster than the solar panels can recharge it. Remember, the more efficient the inverter is at drawing power, the faster your batteries shall be emptied out. To ensure you have the right inverter for your battery, compare the maximum draw of your battery with the watt rating of your inverter.
Understand Your Energy Needs
Ultimately, the key determining factor for the best RV solar panels is the amount of energy that is required to power up your appliances. Take a look at the labels that come with your appliances to understand its power needs. Once this is done, be sure to find a solar panel system whose battery is capable of meeting these power needs.
Here, be mindful of the panel’s output. The output measure is an indication of the panel’s efficiency and effectiveness at recharging the system’s batteries upon use. If your power consumption is likely to be heavy, it is wise to opt for a panel with high energy efficiency as it is capable of recharging your batteries faster than one with low energy efficiency.
Be sure to also match the inverter to your energy needs as well as to your battery bank.
Dig the Costs
The costs involved in acquiring the right solar panels for your needs go beyond merely purchasing your best pick. Consider the cost implications of the installation process.
Does the solar panel system come with all the necessary mounting equipment that I need?
Can I install it on my own or do I need to hire professional help?
What are the maintenance costs involved, if any?
Answering all these questions will help you arrive at a workable balance between a cost-effective and energy-efficient solar panel for your RV.
To ensure that you have a cost-effective solar panel from the word go, ensure that your panel of choice comes with the necessary accessories to eliminate the added costs of purchasing them separately.
A careful consideration of the pros and cons of the solar panels reviewed above has Renogy solar panel (100 Watt).

The fact that they stand behind their product helps to inspire the customer’s confidence in the quality of the solar kit they are purchasing. In the end, it can be a great addition to your RV.
Investing in the best RV solar panels comes with several benefits. You have the freedom to move around knowing that the energy requirements of your appliances are being met. They are also an eco-friendly source of energy that makes use of Mother Nature’s gift of sunlight to satisfy your power needs. Lastly, they are a relatively low maintenance source of power making them a convenient and cost-effective camping companion.
Even as we look to switch off from our daily lives and commune more with nature, we still have basic power needs. We need the power to provide lighting to enable us to find our way around the RV at night and even for security purposes. We also need to keep any foodstuff fresh enough for human consumption if our camping expeditions are for extended periods.
Understanding your energy needs and how different components of the solar panel and the solar panel system in general works is essential. Such knowledge helps to ensure that you choose the best solar panel for your RV. Also, do not forget to check other customers’ experiences with products from different manufacturers. While the reviews are highly subjective and some biased, they help to give you a general expectation of product’s performance.
