For optimal efficiency of your solar panels, we suggest a yearly service to guarantee they’re always functioning properly. This helps detect and address any issues or dips in production. While most panels clean themselves with regular rainfall, local weather, bird activity, and nearby trees might necessitate occasional cleaning. Although it’s rare to need cleaning every year, an annual inspection ensures you aren’t missing out on commercial energy production due to unclean panels.

Commercial Solar Panel Maintenance & Servicing
If your business has solar panels installed, you will want to consider an annual solar panel service to ensure you are producing energy with maximum efficiency. Faulty or dirty solar panels can reduce the generation of energy, so it’s important to get regular maintenance checks on your solar panels. Geo Green Power offers specialist maintenance and servicing for small businesses and large-scale commercial solar panel systems. Take a look at the commercial sectors our expert team covers.
Tips for checking your panels are in good condition:
• Generation reading: A very easy way of assessing the condition of your panels is from the generation meter reading. If it is similar to the estimation in your handbook, then everything is working fine.
• Check the panels: If accessible, then a simple glance at your panels can tell you if there is any surface debris like moss or lichen build-up. If the panels aren’t clean, then this can reduce the power output.
We often get asked ‘What could go wrong with solar panels?’
Solar panels are generally dependable due to their minimal moving components. Nonetheless, while they’re low-maintenance, we advise an annual service to catch and address any issues early, ensuring uninterrupted energy production.
Potential issues that might arise without routine inspections include:
- Birds making nests beneath the panels
- Accumulation of dirt on panels, decreasing efficiency
- The system shutting off during heavy cloud cover or rain
- Error codes displayed on the inverter
- Cracks or damages to the solar panels
- Malfunctioning solar monitoring or metering
- Wildlife chewing on the system’s cables
While these problems are infrequent, they can escalate if not detected and addressed promptly. If you haven’t had your system inspected in the past two years, we suggest scheduling an engineer’s visit.
A key to minimizing system issues is selecting a reputable installer and ensuring high-quality products are used. Prior to finalizing any contract, verify that the workmanship, panels, and inverters come with warranties. Also, ascertain if your chosen company will handle the installation directly or if they’ll subcontract the work.
Issues with solar panels and what to do
If your solar PV system isn’t producing energy or displays a red light, consider resetting the inverter. Turn off both the AC and DC isolators, wait for 5 minutes, then turn them back on. Refer to your Operations and Maintenance Manual to make sure you’re doing this correctly and safely. If the problem persists, ensure that the inverter is connected to the grid and no MCBs or breakers have been tripped. Resetting them might fix the issue.
If your system still isn’t working, it might be time to call an engineer. Often, inverters will show a fault code pointing to the problem. When reaching out to us about a malfunction, please share the inverter’s make, model, and serial number along with the reported fault, so we can assist you effectively.
If you think panels might be damaged or cables appear compromised, report the issue immediately. This ensures a technician can address and rectify the matter promptly and safely.
Common solar faults:
- Underperformance: This may be due to the condition of your panels or cable misalignment.
- Inverter faults: These are usually easily rectified with a simple reset, following the manual.
The great part about solar is that there are very rarely any problems – but after roughly 15 years you can expect to replace the inverter as these don’t have a fantastic shelf life (like the solar panels do).

Solar Panel Maintenance FAQS
Are my solar panels generating as much energy as possible?
One easy way you can check if your panels are performing at their best is to check the estimated annual generation figure, which you can find in your MCS certificate. If this number isn’t accurate to the figure on your generation meter, then this can be a sign that there may be an issue with your system.
Checking your generation figure every quarter is a great habit to get into – especially when you’re approaching the warmer months, as you’ll want your panels working at full capacity and taking advantage of the summer sun!
What is the lifespan on solar panels and inverters?
Most solar panels come with a minimum 20-year warranty – so they’re truly future-proof! If there’s an issue, it’s more likely to be your inverter or power supply.
The lifespan of inverters, unfortunately, isn’t as long as that of the panels. Before you report a fault, it’s worth checking a few things:
- Is there enough ventilation? Inverters can overheat if not provided with space to breathe. Making sure they’re not boxed in or near heat sources (radiators etc) is really important to ensure the longevity of your inverter.
- Is the inverter clean and free of dust? Regularly cleaning your inverter can extend its lifespan, as dust can easily clog up the vents and cause overheating.
Is there a problem with my inverter?
Depending on how good the manufacturer is, inverters typically have a life span between 10-15 years. Fault codes on inverters vary depending on the manufacturer. Some common codes to look out for include:
- Error 509 = No energy is being fed back to the grid. The common cause of this error is dirt or debris on your panels.
- Error 314 = This is a calibration timeout; which should rectify itself when the inverter repeats its start-up routine.
- Green Flashing Light = A connection issue. Once the conditions for the feed-in operation are met, the inverter will start the feed-in operation. Make sure the power supply is secure and connected to the PV system.
What can cause solar panels to stop working?
It is very unlikely that your actual panels will stop working as there are no moving parts, a fault with your system is much more likely to be an error with your inverter. Panels do however stop working if they are damaged from falling objects, if they or the cabling is moved and becomes loose or if they become excessively dirty. All of these issues can be identified during service.
Can you replace just one solar panel?
Yes. In fact, solar panel systems are designed so that you can replace panels easily if it was ever needed.
How much does it cost to replace a broken solar panel?
This will depend on how easy it is for us to reach and replace a specific panel. Costs would vary from £350 + VAT for the panel and work involved.
How do I clean my solar panels?
In most cases, local rainfall and the angle of installation means that solar panels are self-cleaning. However, dust, bird droppings, tree sap, lichen and other dirt can build up so from time to time it is worth cleaning them manually. A spray with a garden hose is often enough to remove surface dirt, or most window cleaning companies will have a reach-and-wash system that can be used to get the panels thoroughly clean in next to no time. We do recommend an annual service of your solar PV system and as part of this, our team can inspect your panels and assess whether they need cleaning.
When are my panels most efficient?
Solar panels will be most efficient when the sun is hitting them directly, which is around midday. Light intensity is the most important factor when considering efficiency – when the sun is lower in the sky, light won’t be as intense and this will reduce the output of your panels. Seasonal changes can also affect the efficiency of your panels, as during the summer, the sun shines for longer than in winter.
From around May to September, your solar PV system will produce more energy than October to April as the days are shorter. However, remember that solar panels don’t need direct sunlight to function. Even on cloudy days, your solar panels will still absorb light and continue to work effectively. Whatever the weather, you can benefit from energy production year-round – it will simply be more effective on sunnier days, and at times when the sun is highest in the sky.
How do I prevent birds from nesting under my solar panels?
Birds can be tempted to nest under solar panels, particularly pigeons who tend to build their nests in awkward places. The area under a solar panel is shaded and offers protection from wind and rain, so it’s no surprise that this can be an issue. There are ways you can prevent it from happening. When we install your solar PV system, we can pigeon-proof your panels – simply ask us about this when you book in a consultation, and we can add it to your order. While we can’t retro-fit pigeon-proofing, we do have a useful guide on how to handle pigeons nesting under your solar panels.
Can leaves, moss and debris gather under or on the panels?
It’s not common for leaves or other plant materials to be a problem, as the panels sit quite close to the roof tiles. However, if leaves were to gather under the panels, they could be dealt with as part of a maintenance visit by a member of our team. Likewise, moss doesn’t typically form on solar panels, but if you have noticed it developing, you can discuss it with whoever is cleaning your solar panels so that they know to take extra care to remove it.
