SOLAR PANELS

Solar panels are the core of any RV solar system. They collect sunlight and convert it into energy to charge your RV batteries. With a good roof-mounted array, you can power up devices and essentials without hookups or gas-powered generators. At etrailer, we stock rigid and flexible solar panels to match every RV type and roof layout.

SOLAR CONTROLLER

The solar controller is the heart of your system, managing the flow of energy from your panels to your batteries. It prevents overcharging, protects battery health, and maximizes the efficiency of every ray of sunlight. With a solar controller, you can trust that your power setup stays optimized and your batteries stay strong.

RV BATTERY

An RV battery stores the energy collected by your solar panels, making it available whenever you need it. During the day, your panels charge the battery; at night or on cloudy days, the battery powers your lights, appliances, and devices. Reliable deep-cycle batteries keep your RV running smoothly no matter where the road leads. etrailer recommends AGM or lithium batteries for longer life and reliable off-grid use.

INVERTER

An inverter transforms stored DC battery power into AC power, letting you use everyday appliances like coffee makers, laptops, and microwaves. An inverter charger can also switch seamlessly between solar, battery, and shore power, keeping your system flexible and ready for anything your journey throws at you.

How do I determine the right size of solar panels for my RV?

Match your energy needs with solar output. A 100W panel typically produces ~30 amp-hours/day. Use etrailer’s solar calculator to estimate based on your appliances and battery capacity.

Can I install an RV solar system myself?

Yes, installing an RV solar system can be a DIY project if you're comfortable with basic electrical work. It's important to follow a step-by-step guide and adhere to safety precautions. If you're unsure, use our Local Installer Locator Tool to find a trusted technician near you and start harnessing solar power with confidence.

What does it mean when an RV is labeled as "solar ready"?

The term "solar ready" can vary between manufacturers. Generally, it means the RV has pre-installed wiring or ports to facilitate the addition of solar panels. However, it doesn't necessarily include all components needed for a complete solar system. It's important to verify what's included and what additional equipment is required.

Can I use solar power to run all my RV appliances?

It depends on your system size and the appliances you want to run. Solar is great for powering lights, charging devices, or running small electronics. For larger appliances like an air conditioner, you’d need a high-capacity battery bank, powerful inverter, and a robust solar setup. Many RVers use solar for essentials and supplement it with a generator for high-power needs.

How do I maintain my RV solar system?

Maintenance is pretty simple! Keep your panels clean—dust, dirt, and debris can reduce efficiency. Check the connections regularly to ensure they’re secure and corrosion-free. Also, monitor your batteries to make sure they’re holding a charge and staying in good condition.

Can I add more solar panels later?

Yes! Most etrailer kits are expandable. Just make sure your controller and wiring are sized for future upgrades.

How do I know if my solar system is working properly?

A solar controller with a display or monitoring app can show you how much power your system is generating and how much charge your batteries have. If you notice your batteries aren’t charging or your power output is low, it might be time to inspect the panels or connections.

Can I still use solar panels if I camp in shaded areas?

Yes, but your system will produce less power. To maximize efficiency, try parking where panels get the most sunlight, even if it's only part of the day. Pairing solar with a generator or larger battery bank can help in low-light situations.
