A Solar System That Is Not Performing Is Costing You Money
One of the less obvious risks of owning a solar system is that underperformance is often invisible. Your lights still work, your inverter still shows green, and life carries on normally. But if your panels are dirty, a connection has degraded, a panel has been damaged, or your inverter is running below capacity, your system is producing less energy than it should be.
Every unit it falls short is a unit you are buying from the grid at Eskom's current tariff. For homeowners, this erodes the monthly saving that made the investment worthwhile. For businesses that installed solar specifically to reduce operating costs and eliminate diesel generator spend, an underperforming system means those savings are not materialising as expected.
Regular maintenance is the most cost-effective way to protect your system's output and extend its lifespan. And when something does go wrong, getting it diagnosed and repaired quickly limits the financial impact.

Solar Repair Services
We diagnose and repair faults across all parts of a solar installation:
Fault Diagnosis & Assessment
If your system is not performing as expected and you are not sure why, we start with a full assessment. We check panel output, inverter performance, and wiring.
Solar Panel Repair & Replacement
Panels can be damaged by hail, debris, or extreme weather. A cracked panel produces less energy. We assess, repair or replace damaged panels.
Wiring and Connection Repairs
Connections can corrode or work loose over time, causing intermittent faults. We inspect and repair wiring and connections as part of routine maintenance.
Inverter Troubleshooting
Error codes, sudden shutdowns, or a humming inverter producing less than it should. We troubleshoot and provide inverter replacements where needed.
Learn More →Battery Fault Diagnosis
Batteries not charging fully, discharging too quickly, or triggering errors. We assess battery health and carry out replacements where needed.
Learn More →Solar Maintenance Services
Routine maintenance keeps your system producing at full capacity and catches small issues before they become expensive ones. We offer maintenance visits for both residential and commercial solar systems:
Panel Cleaning
Dust, pollen, and grime accumulate on panels and reduce the amount of light reaching the cells. We clean panels safely using appropriate methods that do not damage the surface.
System Performance Check
We review your system's production data, check that output matches what it should be given current conditions, and flag any underperforming strings.
Electrical and Connection Inspection
We inspect all accessible wiring, connections, isolators and earthing to confirm they are in good condition and properly secured. Essential for older systems.
Inverter and Battery Health Check
We check inverter logs for error codes, confirm battery state of health, and verify that the system is switching correctly between solar, battery and grid.
Warning Signs Your Solar System Needs Attention
Not all solar faults announce themselves clearly. Here are the most common signs that your system needs a closer look:
| Warning Sign | What It Could Indicate |
|---|---|
| Electricity bill has increased despite having solar | Reduced panel output, inverter fault or battery issue |
| Monitoring app shows lower output than usual | Dirty panels, shading, a faulty panel or string fault |
| Inverter showing error codes or flashing lights | Inverter fault, grid connection issue or overheating |
| Batteries not lasting as long during outages | Battery degradation or a charging fault |
| Visible damage to panels | Physical damage reducing output or creating a safety risk |
| System not switching to battery during outages | Inverter configuration issue or battery fault |
| No data showing on monitoring system | Communication fault, inverter issue or connectivity problem |
