RV Solar System Repair & Upgrades
Local pros test and fix RV solar systems, from panels and charge controllers to wiring and batteries. They also install right-sized upgrades at your site.
Most dead RV solar systems have just one bad link. It could be a charge controller that lost its settings. It could be a roof fitting that rusted. It could be a panel string held back by one shaded or dead panel. Or it could be a battery bank that won't take a charge. A local pro tests panel output, controller behavior, and battery charging on their own. That way you learn which link failed instead of replacing it all.
On-site repairs include charge controller swaps and setup, roof-entry resealing, and wiring repair. Local pros also service MC4 connectors and combiner boxes, fix fusing, and sort out battery hookups. That includes the charge settings a lithium switch really needs.
For upgrades, a local pro sizes the system around how you camp. The pro looks at your overnight power use, how much you rely on a generator, and your roof space. An honest plan sometimes means fewer panels and more battery, or the other way around. The goal is meeting your real needs, not running up the bill.
Sound familiar?
- Batteries no longer reach full charge on sunny days
- The charge controller shows errors or no input
- Solar worked before storage but not after
- One panel string makes far less than the others
- The controller overheats or resets
How the diagnosis works
- Test voltage and current for each panel and string
- Check the controller settings and output
- Check the roof fitting, MC4, and combiner connections
- Check that the battery takes a charge and read its level
- Check the wire size and fuses against the system size
How the repair typically goes
- Replace bad charge controllers and set the right profile
- Fix or replace rusted roof entries and connectors
- Rewire thin or unfused runs to spec
- Rebalance or replace dead panels
- Check full charging under load and record the output
Good fit for mobile repair
- Controller, wiring, connector, and roof-entry repairs
- Adding panels and hooking up batteries
- Checking output and setting the profile
When a shop is the honest answer
- Roof frame repairs under the panel mounts
- Building a full new battery compartment
- Hail insurance claims that need full-array replacement paperwork
Common components and causes
- MPPT charge controllers
- MC4 connectors and combiner boxes
- Roof cable fittings
- Solar panels and mounts
- DC breakers, fuses, and bus bars
- Roof connections worn by sun and heat
- Controllers set to the wrong battery profile
- Wiring too thin, which limits output
- Tiny panel cracks from hail or flexing
- Battery banks too old to hold a charge
Safety first
- Solar panels make power whenever light hits them. A pro treats the array wiring as live during service.
- The wrong charge settings can damage lithium banks. A pro checks the settings on every solar visit.
What affects the price
Every visit starts with diagnosis and a written quote before repair work begins. These factors move the number:
- System size and part class, like controller amps and panel count
- Roof access and how hard the mounting is
- How long the wire run is and the wire size needed
- Battery type and the hookup work
How much does mobile RV Solar Repair cost?
Most mobile RV Solar Repair runs $200 to $800 for most controller and wiring repairs. On-site labor typically runs $120–$175 per hour, with a service call of $95–$150, credited toward the repair. Simple fixes cost the least. The final price depends on parts, roof or slide access, and your rig make and model. These are rough ranges, not a quote. Every visit starts with an on-site check and a written quote before any work.
- Charge controller replacement
- $250–$600
- Panel wiring or connector repair
- $150–$400
- Battery and charging diagnosis

Frequently asked questions
Is it worth repairing an older RV solar system?
Usually only one part has failed. That could be the controller, the wiring, a panel, or the batteries. Fixing that one part costs far less than a whole new system. Replacement makes sense when the panels are badly worn. It also makes sense if the system was too small from the start. A local pro tests each part on its own. Then you can decide based on real numbers, not guesses.
How is mobile RV repair priced?
You pay a service-call fee that covers travel and diagnosis. Then you pay for parts and labor on the repair you approve. A local pro gives you the diagnosis and a clear quote before any repair work starts. A pro never works on an open-ended okay. A few things change the price. Those are the part type, how hard the access is, and the size of the repair. Each service page explains this.
How quickly can a local pro get to me?
It depends on a few things. Your spot in the service area matters. So does how busy local pros are and whether your problem is an emergency. A local pro books scheduled visits for a time window and puts emergency calls first by safety. When you call, we take your request and share a real ETA from the pro instead of a blanket promise. We also follow up with you if the schedule changes.
