Why Solar Panel Maintenance Matters
Solar panels have no moving parts, but the complete solar energy system includes electrical equipment, roof-mounted components, cables, isolators, an inverter and, in many homes, battery storage.
Performance can be affected by:- Dirt, leaves, pollen or bird droppings
- Shading caused by growing trees or new structures
- Loose, damaged or weathered components
- Inverter or battery warning messages
- Interrupted internet or monitoring connections
- Changes to battery or tariff settings
- Roof repairs or alterations
- Accidental damage
- Pest activity beneath the solar array
- Normal equipment ageing A maintenance inspection can help distinguish between normal seasonal variation and a technical issue requiring further investigation.
Maintenance That Supports Your Warranty
Solar installations normally include several separate warranties. Each warranty protects a different part of the system and has its own conditions.
Solar Panel Product Warranty - The product warranty normally covers eligible manufacturing or material defects in the solar modules.
Solar Panel Performance Warranty - The performance warranty relates to the minimum level of panel output promised by the manufacturer over a stated period.
It does not guarantee that your entire household system will generate a fixed amount every year. Actual generation is also affected by weather, shading, orientation, system availability and electricity usage.
Inverter and Battery Warranties - Inverters and battery systems have separate manufacturer warranties. Battery warranties may also refer to operating temperature, installation conditions, usage, cycles, energy throughput, internet connectivity or approved settings.
Workmanship Warranty - The workmanship warranty covers qualifying defects arising from the installation work. Its scope and duration are stated in the documents supplied with your system.
Insurance-Backed Guarantee - Where applicable, an insurance-backed guarantee provides protection for the installer’s workmanship warranty if the installer ceases trading, subject to the policy’s terms, registration requirements, exclusions and claim procedures.
How to Help Keep Your Solar Warranties Valid
Warranty conditions vary between manufacturers. Customers should always follow the specific documents supplied with their installation.
As a general precaution:
1. Keep your quotation, contract, invoice, MCS certificate, commissioning documents and warranty certificates.
2. Register any equipment or insurance-backed guarantee where registration is required.
3. Retain the model and serial numbers for your panels, inverter and battery.
4. Keep your monitoring system connected wherever the manufacturer requires online access or operating records.
5. Report faults, warning messages, damage or unexpected performance reductions promptly.
6. Do not open, dismantle, relocate or modify the inverter, battery or electrical equipment yourself.
7. Do not allow unqualified persons to alter the solar installation.
8. Obtain advice before roofing work, loft conversions, extensions or electrical alterations near the system.
9. Use suitable cleaning methods and avoid abrasive chemicals, pressure washing or equipment that could damage the panel glass, seals, cables or roof.
10. Keep written maintenance reports, photographs, fault codes and correspondence relating to the system.
USOLAR maintenance does not replace the terms of the relevant manufacturer, workmanship or insurance policy. A warranty claim remains subject to the applicable warranty provider’s assessment and conditions.
Warning Signs That Your Solar System Needs Attention
Contact USOLAR when you notice:
- A red warning light or repeated fault code
- No generation during daylight
- A sudden unexplained fall in output
- An inverter repeatedly switching off
- A battery that no longer charges or discharges normally
- Damage following high winds, hail or building work
- Loose cables or visible damaged components
- Water ingress near electrical equipment
- Burning smells, unusual heat or electrical noises
- Loss of access to the monitoring application
- Persistent roof leaks close to the installation
Where there is smoke, fire, exposed live equipment or an immediate electrical danger, keep away from the equipment and contact the emergency services or the relevant electricity emergency service.
Frequently Asked Questions
-
Do solar panels need annual maintenance?
Solar panels generally require limited maintenance. However, the complete installation includes an inverter, electrical protection, mounting equipment and potentially a battery. Periodic monitoring and inspection can help identify faults, safety concerns and performance issues. The appropriate interval depends on the equipment, installation environment, manufacturer instructions, property insurer and any maintenance conditions contained in the customer’s warranty documents.
-
Can DIY repairs invalidate a solar warranty?
Unauthorised modification, dismantling or unsuitable repairs may affect a warranty claim. The exact position depends on the manufacturer’s terms and the cause of the fault. Contact USOLAR before opening, moving or altering any part of the system.
-
How often should a solar inverter be serviced?
The inverter should be kept ventilated, monitored for warnings and operated in accordance with the manufacturer’s instructions. A technical inspection may be advisable when fault codes appear, performance changes or the system reaches a recommended inspection interval.
-
Do storage batteries require maintenance?
Modern batteries generally require limited physical maintenance, but their operating environment, software, settings, connectivity and charging behaviour should be monitored. Customers should follow the battery manufacturer’s temperature, location and usage requirements.
-
What documents should I retain for my solar warranty?
Keep your contract, invoice, MCS certificate, system design, commissioning documents, electrical certificates, equipment datasheets, serial numbers, warranty certificates, insurance-backed guarantee and maintenance reports.
-
Can USOLAR maintain a solar system installed by someone else?
In many cases, yes. We will first assess the equipment, available documentation, system condition and any existing warranty restrictions.
-
What should I do when my inverter shows a fault code?
Record the full code, take a photograph and check whether the system returns to normal after any manufacturer-approved basic reset procedure. Do not repeatedly reset, dismantle or alter the equipment. Send the fault information to USOLAR if the warning remains or returns.
-
What happens if my solar installer has stopped trading?
Check your handover documents and MCS certificate for details of any insurance-backed guarantee. Contact the named insurance provider and follow its claims procedure. USOLAR may also be able to inspect the system and provide a report, subject to the system’s condition and access.
