SOLAR PANELS

Your Off-Grid Power Source

The foundation of any solar setup, panels collect sunlight and charge your RV batteries. At etrailer, we carry rigid, flexible, and portable options to fit different roof layouts and camping styles.

SOLAR CONTROLLER

Optimize Every Ray

The controller regulates energy flow from panels to batteries, preventing overcharging and improving efficiency. Choose the right size now, and you’ll be ready for future panel upgrades.

RV BATTERIES

Store Power for Anytime Use

Your battery bank keeps your RV running at night and on cloudy days. etrailer recommends AGM for dependable performance or lithium for longer life and lighter weight.

INVERTER

Power for Everyday Appliances

An inverter converts battery DC power into household AC power for laptops, coffee makers, and microwaves. Pure sine wave models protect sensitive electronics; inverter/chargers add seamless switching between solar, battery, and shore power.

How do I choose the right panel size?

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.
