Installing solar panels is a smart investment, but like any piece of equipment, they need to be looked after to work properly over the long term. In Scotland, the weather can be tough on rooftops and outdoor systems, regular servicing makes a real difference. We’ll explains what solar panel servicing involves, why it matters, and how to keep your system running efficiently for years to come.
Why Solar Panel Servicing Matters
Solar PV systems are built to be low maintenance, but that doesn’t mean they’re maintenance-free. Over time, dirt, moss, bird droppings and debris can reduce how much sunlight reaches the panels. Wiring, inverters and mounting systems can also wear out or become damaged especially after strong winds or heavy snow.
By having your solar panels checked regularly, you reduce the risk of performance loss and unexpected breakdowns. Servicing helps spot small issues before they turn into expensive problems. It also ensures your system stays compliant with warranty terms and, if you’re claiming payments via schemes like the Smart Export Guarantee (SEG), that you’re meeting the conditions for ongoing eligibility.
What’s Involved in a Solar Panel Service?
A full service of your solar PV system includes both physical inspection and performance checks. A typical service in Scotland includes the following steps –
- Visual inspection of all panels for cracks, damage or build-up of debris
- Testing of the inverter to ensure it’s operating correctly
- Check of all cabling, isolators and electrical components
- Measurement of system output to compare against expected performance
- Inspection of mounting frames and fixings to ensure safety and stability
- Optional cleaning if the panels are significantly dirty or obstructed
For larger or more complex systems, including those with battery storage or integrated EV charge points, the service may include additional checks. This is particularly important for commercial setups or any home with a higher energy demand.
How Often Should Solar Panels Be Serviced?
Most manufacturers recommend a service every 1 to 2 years. In some areas of Scotland where the weather can be more severe – such as rural or coastal locations – it might be a good idea to book an annual service. This helps maintain the safety and output of your system and gives you peace of mind through the winter months.
Panels that are surrounded by trees or exposed to bird activity may need more regular cleaning or checks. Your installer can advise based on the position and layout of your system.
Who Should Service Your Solar Panels?
Always use a qualified professional to service your solar PV system. It’s recommended to work with a certified installer who follows the standards set by the Microgeneration Certification Scheme (MCS). This ensures the work is done safely and to a high standard.
Jorro offers solar panel servicing across Glasgow and Central Scotland. Our team is experienced in working with both domestic and commercial systems, and we ensure all checks are carried out properly, with a clear report provided at the end.
If you’re unsure whether your system needs a service, we can carry out an inspection and advise on the best course of action. If performance has dipped or you’re seeing error messages on your inverter, it’s worth booking a visit as soon as possible.
What If Repairs Are Needed?
During a service, if we find a fault or worn component, we’ll let you know right away. Most issues can be sorted with simple repairs or replacements. Common repairs include replacing fuses, repairing wiring, or fitting a new inverter if the old one is failing.
If your panels are damaged (for example, by falling branches or storms), we’ll help you understand what’s covered under your warranty and what your options are. Our aim is always to get your system back to full performance quickly and affordably.
Keeping Track of Performance
Many modern solar PV systems include monitoring software that shows how much electricity your system is generating. This is a useful tool to track performance over time. If you notice a sudden drop in output, or the system is producing less than expected over a long period, it could be a sign that servicing is due.
The Energy Saving Trust also offers advice on what output levels to expect based on the size of your system and your location in Scotland. Monitoring your energy generation helps you spot changes early and take action if needed.
Winter Considerations in Scotland
Scottish winters can be tough on solar panels. While snow usually slides off panels due to their tilt, ice build-up or high winds can still cause wear and tear. After winter, it’s a good time to book a service to check for any damage caused by storms or debris. This is also a good opportunity to clean the panels and prepare for spring and summer when generation levels increase.
Combining Solar Panel Servicing with System Upgrades
If your solar PV system is several years old, a service visit can also be a good time to consider upgrades. Newer inverters, battery storage systems, or solar-compatible EV chargers can increase your energy independence and make better use of the electricity your panels generate.
At Jorro, we can assess whether your system is suitable for add-ons like battery storage or smart monitoring. This not only improves efficiency but also helps future-proof your setup as energy use evolves.
