If you’ve noticed your electric bills climbing or your monitoring app showing unexplained dips in production, you’re probably asking yourself if you should repair your solar panels. The good news is that most of the time, solar panel repair is worth it.
With systems designed to last 25 to 30 years, addressing issues early can restore lost production and protect your investment. The right choice depends on the type of problem, the age of your system, and whether a fix will meaningfully improve performance.
How to Know When Solar Panel Repair Is Worth It
Knowing when solar panel repair is worth it comes down to how much performance you can restore and whether the fix extends your system’s lifespan. By spotting early signs, weighing repair vs. replacement, and considering warranty coverage, you can decide the best path for your solar investment.
Signs You Should Repair Your Solar Panels
Your solar system will usually give you clues when something’s wrong. Here are a few red flags to watch for:
Sudden drops in energy production on clear, sunny days.
Error messages or alerts from your inverter or monitoring system.
Visible panel damage like cracked glass, discoloration, or loose wiring.
Higher energy bills without a logical reason like cloudy weather.
Tripped breakers or power interruptions that point to electrical issues.
If you’re seeing any of these, it’s often a good sign that repair will restore performance and prevent bigger problems later. GreenLancer has a national solar repair network that is skilled in pinpointing and fixing issues. Complete this form to get started.
Repair vs. Replace Solar Panels
So, how do you decide between solar panel repair vs replacement? A repair usually makes sense if:
Your solar panels are less than 20 years old.
The problem is limited to one or two components (like an inverter or connector).
Replacement parts are readily available and possibly covered under warranty.
Replacement may be the better option if your system is near the end of its life span (25 to 30 years), has severe structural damage that makes repair cost-prohibitive, or your home needs more power.
In most cases though, fixing the issue is the smart move. It restores performance, saves money, and keeps your clean energy system running strong.
Key Factors in Deciding to Repair or Replace Solar Panels
Deciding whether to repair or replace solar panels depends on more than just the visible issue. Age, warranty coverage, insurance, and long-term savings all play a role in finding the best option for your home.
Age of Your Solar Panels and System Lifespan
Most solar panels are designed to last 25 to 30 years, with gradual efficiency declines over time. If your system is still relatively young, under 15 to 20 years old, solar panel repair often makes sense because it can restore years of productive use. However, if panels are nearing the end of their lifespan, investing in repairs may not deliver enough return compared to replacing the system.
Warranty Coverage and Homeowners Insurance for Repairs
Warranty coverage can make the difference between paying full price for a repair or only covering only labor:
Solar panel warranties: Performance coverage usually lasts 25 years, while product warranties range from 10 to 25 years.
Inverter warranties: Typically 10 to 12 years, but many manufacturers offer extended coverage up to 20 years.
Microinverter warranties: Often 20 to 25 years, designed to align with panel lifespans.
Keep in mind:
Labor warranties are often shorter and may have expired.
If your solar company went out of business, parts may still be covered, but you’ll pay for labor.
Many homeowners’ insurance policies treat solar panels as part of the home, so storm or accident damage may be covered, reducing out-of-pocket repair or replacement costs.
Comparing Solar Panel Repair vs Replacement Costs and Benefits
If your repair costs are modest and your system is under 20 years old, repair usually makes more sense. But if repairs are extensive, your system is older, or you want to take advantage of newer technology, replacement may be the smarter investment.
When weighing solar panel repair vs replacement, consider both the financial and practical impacts:
Repair Benefits:
Usually less expensive upfront, especially for minor issues like cracked glass, loose wiring, or inverter replacement.
Restores lost output quickly, helping you save on utility bills.
Extends the lifespan of your existing system without a large new investment.
Replacement Benefits:
Newer panels are more efficient, often producing more power in the same space.
May qualify for tax credits or rebates that lower installation costs.
Provides a fresh warranty, protecting you for another 20+ years.
Hiring a Solar Repair Company vs DIY Fixes
While some minor troubleshooting can be handled yourself, most solar repairs are safest when performed by licensed professionals. Attempting complex electrical repairs without training can lead to safety hazards and expensive mistakes, so bringing in an expert is the better option for most homeowners.
DIY Fixes: Checking your monitoring software, resetting your inverter, or cleaning debris from panels can often be done safely. Always follow manufacturer instructions to avoid voiding warranties.
Professional Repairs: Issues like inverter failures, wiring faults, ground faults, or shading-related hot spots require a qualified technician. GreenLancer’s repair network of vetted professionals can access proper replacement parts.
