Understanding Commercial
Solar PV Maintenance

Effective commercial solar panel maintenance goes far beyond basic cleaning. It involves technical checks, performance monitoring, and fault rectification.

Key Maintenance Factors Included in Our Service:

Service Area	Description
Performance Monitoring	Regular checks of generation data against predictions to quickly identify any drops in output caused by soiling, shading, or component failure.
Visual Inspections	Thorough inspection of panels for physical damage (cracks, delamination), checks on mounting and racking systems for secure fixings, and assessment of roof integrity.
Electrical Testing	Advanced DC/AC testing, string and inverter testing, and insulation resistance checks to identify faulty connections invisible to the naked eye.
Inverter Health Check	Diagnostics on inverters, ensuring firmware is updated and operating parameters are correctly set to maximise efficiency and lifespan.
Cleaning	Professional cleaning of the array (if required) to remove dirt, debris, and biological growth that can significantly impact output, especially in agricultural or urban settings.

Costs of Commercial Solar Panel Maintenance

Servicing Costs: Starting from £599.
*Costs may vary depending on system size and location.

The cost of commercial solar panel maintenance varies depending on the system size, the accessibility of the array, and the level of service required (e.g., reactive vs. annual preventative maintenance contract).

Cost-Benefit: While there is a cost, our clients consistently find that an investment in regular maintenance is heavily outweighed by the return achieved through maximised system performance and the avoidance of expensive, unexpected faults.

Our solar consultants will thoroughly evaluate your existing system and offer a clear, fixed-price contract for comprehensive solar panel maintenance services. Call our team today.

Commercial Portfolio Maintenance

We manage maintenance contracts for multi-site clients with large-scale arrays, ensuring consistent performance and simplified compliance across their entire solar portfolio, regardless of their location.

You’re one step closer to helping Geo Green Power plant a tree!

We plant a tree for every quote we produce. Like any business, we’re aware that our operations have an impact on the environment and there are three big reasons we believe we should do something about it – our team, our customers and the future of our planet. We’ve chosen to support TreeApp’s programme to plant trees across the globe.

Solar Panel Maintenance FAQs

It’s not common for leaves or other plant materials to be a problem, as the panels sit quite close to the roof tiles and shouldn’t be installed in areas where trees may shade them. 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.

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 a consultation, and we can add it to your order. While we don’t offer to retrofit pigeon-proofing, we do have a useful guide on how to handle pigeons.

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 from 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.

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 no time. We do recommend an annual service for your solar PV system, and as part of this, our team can inspect your panels using a drone and assess whether they need cleaning.

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 (and depending on location).

Yes. In fact, solar panel systems are designed so that you can easily carry out solar panel replacements if they are ever needed.

It’s 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 by falling objects, if they or the cabling are moved and become loose, or if they become excessively dirty. All these issues can be identified during service.

Depending on your manufacturer, inverters typically have a life span between 10-15 years. Fault codes on inverters vary, but 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.

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 your 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 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 vents and cause overheating.

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 the O&M manual. If this number isn’t accurate to the figure on your generation meter, then this is 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!
