Keep the Juice Flowing: RV Solar Panel Maintenance & Repairs

Why Bother With Solar Panel Maintenance?

If you’ve got solar panels on your RV roof, you already know they’re a game-changer. Free power from the sun = less generator noise, fewer campground hookups, and more freedom. But just like anything else on your rig, panels need a little love to keep working at their best.

1. Keep Them Clean (Without Scratching)

Dust, pollen, bird gifts (you know what I mean) — all that gunk cuts down how much sunlight your panels can actually grab.

• Quick fix: a soft brush or microfiber cloth with water.

• Skip: abrasive cleaners or stiff brushes — scratches kill efficiency.

• Pro tip: If you’re boondocking in dusty areas, give them a rinse every couple of weeks.

2. Check the Wiring & Connections

Road vibrations are brutal. Loose wires and cracked connectors are common culprits when your solar setup stops working.

• Look for frayed or pinched wires.

• Make sure connectors are snug and corrosion-free.

• A dab of dielectric grease helps keep moisture out.

3. Inspect the Mounts & Seals

Your panels are bolted (or glued) to your roof, which means leaks can sneak in if seals crack.

• Twice a year, climb up there and look for cracked sealant around the mounts.

• Reseal with RV roof sealant before a drip turns into a downpour inside.

4. Monitor Performance

If your batteries aren’t holding charge like they used to, it might not be the batteries — it could be the panels.

• Most solar charge controllers show input voltage/amps.

• If numbers look off, test the panel output directly with a multimeter.

5. Know When It’s Time for Repairs or Replacement

Solar panels can last 20+ years, but RV life is harder than rooftop life.

• Cracks in the glass? Time to replace.

• Big dips in power output? Could be internal cell damage.

• For wiring or controller issues beyond your comfort level, call a pro.
