Why Solar Maintenance Matters
Solar panels are often marketed as maintenance-free — and while it's true that they have no moving parts, this does not mean they require no attention. The reality is that solar systems are exposed to the full force of the Irish climate year-round: rain, wind, frost, bird activity, and seasonal debris all take a gradual toll on performance and safety. Without regular inspection and servicing, the impact is largely invisible — your system appears to be working, but it's generating less electricity and accumulating risks that could prove costly.
Inverter faults are one of the most common and least noticed issues in solar systems across Ireland. An inverter operating outside of its optimal parameters may continue to run while quietly losing efficiency or logging error codes that never trigger an alert. Without monitoring and periodic diagnostic checks, these faults can persist for months — costing real money in lost generation. Similarly, cable connections and mounting hardware that have worked loose over time pose both electrical and structural safety risks that a visual inspection alone won't catch.
For farms and commercial properties in Roscommon where electricity loads are high and systems are large, the financial stakes of undetected underperformance are even greater. A professional annual maintenance visit from Saunderson Solar provides a complete picture of your system's health — and the peace of mind that comes from knowing it's working as it should.
- ✓Dirt, moss, and debris reduce panel output
Ireland's climate encourages moss and lichen growth on panels. Even a partial build-up across a portion of the panel surface reduces the electricity that panel can generate.
- ✓Inverter faults often go unnoticed without diagnostics
Inverters can operate in a degraded state for extended periods. Regular diagnostics catch faults early — before they affect your generation figures and your savings.
- ✓Gradual efficiency loss is almost impossible to self-detect
A 10% drop in output is rarely noticeable day to day. Only by comparing your current performance against baseline generation data does the picture become clear.
- ✓Electrical safety risks require qualified inspection
DC wiring on solar systems operates at voltages that require professional handling. Loose connectors, damaged cables, and water ingress points must be identified and addressed by RECI-certified electricians.
- ✓Warranty and insurance protection depends on maintenance
Many solar equipment warranties and property insurance policies include conditions around maintenance. A documented annual service visit protects your coverage and the long-term value of your investment.
Key Benefits of Professional Maintenance
Regular servicing by qualified engineers delivers measurable results — not just reassurance. Here's what a professional maintenance programme delivers for solar system owners across Roscommon.
Maximum Energy Output
A well-maintained solar system generates closer to its rated capacity. Identifying and resolving shading issues, cleaning build-up, and correcting inverter settings can restore output that has been quietly lost over time — returning real financial value.
Early Fault Detection
Catching problems early is almost always cheaper than dealing with the consequences later. Our diagnostic checks identify inverter errors, connection degradation, and panel faults before they become serious — saving you significant repair costs.
Extended System Lifespan
Solar panels that are properly maintained and kept free from sustained soiling, moisture ingress, and physical stress consistently perform closer to their 25–30 year rated lifespan. Maintenance is the most cost-effective way to protect that long-term potential.
Electrical Safety Assurance
Solar DC systems operate at high voltages and must be inspected by qualified professionals. Our RECI-certified electricians carry out thorough electrical testing to ensure your system remains safe, compliant, and free from hazards — protecting your family, employees, or livestock.
Better Return on Investment
Every percentage point of lost output represents money that should be in your pocket but isn't. Regular maintenance ensures your system is delivering the savings you invested for — making the cost of a maintenance visit many times smaller than the cost of ignoring one.
Peace of Mind Monitoring
With remote monitoring configured and verified during each maintenance visit, you have continuous visibility of your system's health. And Saunderson Solar monitors your system too — alerting you to issues before you'd typically notice them yourself.

What's Included in Our Maintenance Service
Every Saunderson Solar maintenance visit follows a structured checklist developed in line with SEAI installer standards and IEC 62446 testing requirements. We don't do a quick visual check and leave — we carry out a thorough, documented inspection of every component in your system.
-
Panel Inspection & Soiling Assessment
We inspect each panel for physical damage, micro-cracking, soiling patterns, and signs of delamination or discolouration. We assess whether soiling levels are affecting generation and advise on cleaning where required.
-
Mounting System Integrity Check
All mounting brackets, rails, clamps, and roof penetration points are checked for corrosion, movement, and structural integrity. Loose fixings and compromised weatherproofing are identified and noted for remediation.
-
Electrical Safety Testing
DC string voltages and currents are measured and compared against expected values. Insulation resistance testing is carried out on DC wiring. All AC connections at the inverter and consumer unit are inspected and tested to I.S. 10101 standards.
-
Inverter Diagnostics & Firmware Check
We download and review inverter event logs, check for error codes, verify settings, and confirm the unit is operating within manufacturer specifications. Firmware updates are applied where available and appropriate.
-
Cable & Connector Inspection
All DC connectors (MC4 and similar) are inspected for signs of arcing, moisture ingress, or physical damage. Cable routing is checked for UV exposure, chafing, or rodent damage — a common issue on agricultural installations.
-
Performance Comparison & Generation Analysis
We compare your system's current output against historical generation data and expected performance for your location and system size. Any shortfall is investigated as part of the service visit.
-
Monitoring System Verification
We verify that your monitoring system is correctly logging data, that alerts are configured, and that the data we're seeing accurately reflects your system's real-world performance. Calibration adjustments are made where needed.
Our Solar System Health Check Process
Every maintenance visit follows the same structured six-stage process — ensuring nothing is missed and every finding is documented.
System Performance Review
We begin by pulling your generation data and comparing current output against your system's historical baseline and expected performance for the period.
Visual Roof Inspection
A thorough visual inspection of all panels, mounting hardware, roof penetrations, and cable routing. We look for physical damage, soiling, movement, and weatherproofing integrity.
Electrical Safety Testing
DC and AC electrical testing to I.S. 10101 and IEC 62446 standards. String voltage, insulation resistance, and continuity measurements are taken and documented.
Inverter Diagnostics
Full inverter event log review, error code analysis, settings verification, and firmware status check. Any adjustments are made during the visit where possible.
Monitoring Analysis
We verify monitoring data accuracy, check alert configurations, and confirm that remote monitoring is correctly capturing real-time system performance and flagging anomalies.
Service Report & Recommendations
A written service report covering all findings, test results, and specific recommendations is issued to you following the visit. All documentation is retained on file.

Book Your Maintenance VisitCommon Solar Problems We Fix
These are the most frequent issues we encounter when carrying out maintenance and troubleshooting visits across Roscommon and the surrounding areas. Many of them are invisible to the untrained eye — but all of them are affecting your savings.
Reduced Generation Output
Your system is producing less than it should — but because the decline is gradual, it's rarely obvious. We identify the cause: soiling, shading changes, panel degradation, or string faults, and advise on the most effective resolution.
Inverter Errors & Fault Codes
Inverters log error codes that often clear and reappear without ever triggering a user alert. We download and interpret the event log — identifying recurring faults that indicate a component issue before it becomes a complete failure.
Monitoring System Offline
A monitoring system that's offline or logging incorrect data gives you a false picture of your system's performance. We diagnose connectivity issues, reconfigure data loggers, and ensure your monitoring reflects reality.
Wiring Faults & Connector Failure
DC connector failure — particularly in older MC4 connections — is a leading cause of arc faults and fire risk in solar systems. We inspect every connector and replace any showing signs of overheating, moisture, or physical damage.
New Shading & Obstruction Issues
Trees grow, buildings are extended, and satellite dishes get repositioned. A shading issue that didn't exist when your system was installed can significantly affect one or more strings. We identify shading sources and assess the impact on generation.
Water Ingress & Seal Degradation
Roof penetrations and cable glands can degrade over time — particularly after severe Irish winters. Water ingress into junction boxes, inverters, or conduit is a serious risk. We inspect all weatherproofing points and identify areas of concern before damage occurs.
Monitoring & Ongoing Support Plans
A single annual maintenance visit is a sound investment. For customers who want continuous oversight and priority access to Saunderson Solar's team, we offer ongoing support plans that combine remote monitoring, annual servicing, and guaranteed response times.
Our remote monitoring service means we're watching your system's performance data continuously — not just once a year. If generation drops unexpectedly, if an inverter begins logging errors, or if your monitoring system goes offline, we'll know about it and contact you before it becomes a significant issue.
- Remote performance monitoring 365 days a year
We track your system's output continuously and compare it against expected generation. Deviations trigger an investigation before they become costly.
- Performance alerts and proactive notifications
If your system drops below expected output levels, you're notified immediately. We investigate the cause and advise on next steps without waiting for your annual visit.
- Annual servicing included as standard
Every support plan includes a scheduled annual maintenance visit — covering the full checklist of panel, inverter, electrical, and monitoring checks — with a written report.
- Priority support response
Support plan customers receive priority response for fault calls and emergency visits. If your system goes down, you move to the front of the queue.
- Long-term maintenance contracts available
For commercial properties, farms, and larger residential systems, multi-year maintenance contracts are available with fixed annual pricing and dedicated account management.
Certifications, Safety & Compliance
When it comes to electrical safety, the qualifications of the people working on your system matter enormously. Here's what our certifications mean in practice — and why they matter to you.
SEAI Approved Installer
Saunderson Solar holds SEAI approved installer status — meaning we meet the technical competence, insurance, and quality standards required by the Sustainable Energy Authority of Ireland. For maintenance customers, this accreditation provides assurance that your system is being serviced to a nationally recognised standard — and that our work is backed by an organisation with regulatory standing in the Irish energy market.
RECI Certified Electricians
All electrical testing and maintenance work is carried out by RECI-registered electricians. RECI — the Register of Electrical Contractors of Ireland — certifies contractors who meet competence, insurance, and safety standards for electrical work in Ireland. When a RECI-certified electrician works on your solar system, you can be confident the work is carried out safely, correctly, and in compliance with Irish electrical regulations. You'll receive a Certificate of Completion for all notifiable electrical works.
I.S. 10101 Compliance
The National Wiring Rules (I.S. 10101) for Electrical Installations (I.S. 10101) govern all electrical work in Ireland — including the integration of solar PV systems with domestic and commercial electrical infrastructure. Our maintenance procedures follow I.S. 10101 requirements as standard. This ensures that every electrical test we carry out, and every connection we inspect or modify, is done in accordance with current national standards — protecting your safety and your system's legal compliance.
IEC 62446 Testing & Documentation
IEC 62446 is the international standard for the documentation, commissioning, and periodic testing of PV systems. Our maintenance service follows the testing protocols defined in this standard — covering insulation resistance, continuity, and performance verification — and we provide documentation that records test results in the format required by this standard. This is particularly important for commercial and agricultural customers whose systems may be subject to insurance audits or regulatory inspection.
