Restore Your Solar Performance with Hi-Connect Solar and Electrical
A solar energy system is a long-term investment in clean, cost-effective energy—but like any complex electrical system, it can experience faults or degradation over time. If your system isn’t producing as expected, shows error messages, or has damaged components, it may be time for a professional repair.
At Hi-Connect Solar and Electrical, we specialise in safe and reliable solar system repairs for residential and commercial installations across New South Wales. Whether your system was installed recently or several years ago, and whether we installed it or not, our team can diagnose and resolve a wide range of issues.
Why Solar Repairs Are Important
When your solar system malfunctions, it doesn’t just waste energy—it wastes money. Many issues can go unnoticed until a major drop in performance or a power bill spike draws your attention. Acting early can:
- Prevent complete system failure
- Protect your warranty
- Avoid safety hazards like electrical faults and fires
- Restore your energy savings
At Hi-Connect Solar and Electrical, we don’t just patch over problems—we get to the root of the issue and offer practical, lasting solutions.
Common Solar System Issues We Repair
1. Inverter Failures
Your inverter is responsible for converting the DC power from your panels into usable AC power for your home. It’s often the most complex and sensitive part of the system—and also one of the most common to fail.
Signs of a faulty inverter include:
- Blinking red lights or fault codes
- No output or low voltage
- Frequent shutdowns
- No power during daylight hours
We’ll diagnose the issue and, depending on the situation, either repair the inverter or recommend a suitable replacement.
2. Panel Damage or Degradation
Solar panels are designed to last 20–25 years, but they’re still vulnerable to:
- Cracks from hail, branches, or impacts
- Water ingress
- Hot spots or discoloration
- Burn marks or delamination
If your panels are cracked or broken, they can not only reduce system performance but also pose a fire risk. We offer full solar panel replacement services using high-quality, compatible models matched to your existing system.
3. Wiring Issues
Faulty or degraded wiring is a leading cause of solar underperformance and safety hazards. Over time, connections may loosen, corrode, or suffer from animal damage.
We repair or replace:
- Frayed or chewed cables
- Loose or corroded connectors
- Faulty DC isolators
- Conduit and junction boxes
Every wiring repair is carried out by a licensed electrician, ensuring your system is restored safely and to current Australian Standards.
4. Monitoring System Failures
Many solar owners rely on online monitoring systems to track performance. If your system is no longer reporting data, we can:
- Reset communication between your inverter and Wi-Fi
- Repair faulty data loggers
- Update or reinstall monitoring software
- Replace non-functioning display units
This is particularly useful for early fault detection and system optimisation.
5. Water Leaks and Roof Integrity
Improper installations can lead to leaks where the panel mounting hardware penetrates your roof. We can reseal or reflash roof penetrations and install upgraded mounting hardware if needed.
How We Approach Repairs
When you contact Hi Connect Solar and Electrical, here’s what you can expect:
1. Thorough Fault Diagnosis
We begin with a comprehensive system check to identify the root cause of the problem. This includes:
- Visual inspection of all components
- Testing of string voltage and current
- Inverter diagnostics and error code interpretation
- Monitoring performance logs (if available)
2. Clear Quotation and Advice
Once we’ve diagnosed the issue, we’ll provide a clear quote and a breakdown of the required repairs. We’ll also explain whether the repair is covered under warranty (if applicable) and whether insurance may apply.
3. Fast, Professional Repairs
Our licensed technicians will carry out repairs efficiently, using quality components and safe procedures. In most cases, we complete repairs on the same day.
4. System Testing and Report
After repairs, we thoroughly test the system to ensure it’s back to peak performance. You’ll receive a written report summarising the work completed, along with any maintenance recommendations.
Replacement vs. Repair—What’s Best?
Sometimes, it makes more sense to replace older components rather than repair them—especially if they’re out of warranty or using outdated technology. We’ll always provide you with honest advice and options tailored to your budget and energy goals.
Inverter replacements, panel upgrades, or rewiring can improve your energy yield and often come with new warranties, ensuring long-term peace of mind.
Repairing Systems We Didn’t Install
At Hi Connect Solar and Electrical, we’re happy to repair systems even if they were installed by another company—especially if your original installer is no longer in business (which unfortunately happens more than it should). We’re experienced in working with systems of all makes, models, and configurations.
We also provide solar health checks for older or inherited systems that may never have been properly inspected.
Transparent Pricing
Repair costs vary based on the issue and system type, but we always provide upfront pricing. As a guide:
- Inverter fault diagnostics: from $150
- Inverter replacement (standard single-phase): from $1,000
- Panel replacement: from $250–$400 per panel
- Wiring repairs: from $100–$500 depending on severity
- Monitoring repair or setup: from $120
- Emergency Call-out fee: $150
We’ll never go ahead with a repair unless you approve the cost first.
