Keep your solar system running at peak performance with Spectrum Energy Systems. We are MCS-certified installers who have been fitting and servicing solar since 2011, and we maintain systems across the East Midlands whether we installed them or not. An annual service protects your output, your warranty evidence and your savings.
Why Regular Maintenance Matters
Even the most reliable solar PV systems benefit from routine checks to maintain peak performance. An annual health check lets our engineers:
- Detect faults early—before they impact energy generation.
- Prevent output loss caused by dirt, weather damage, or wildlife interference.
- Extend the lifespan of your solar panels, inverters, and cabling.
- Protect your energy savings and maximise long-term return on investment
With just one professional check-up each year, you can keep your system running smoothly—no surprises, no downtime.

Troubleshooting Common Solar Issues
We handle a range of common issues to keep your solar system running smoothly:
- Inverter errors or red warning lights
- Reduced energy output caused by dirt, shading, or debris
- Wildlife interference or damaged cabling
- Monitoring system malfunctions
- Cracked or weather-damaged panels
Not sure what’s wrong? Begin by checking your generation meter against expected values, reviewing inverter error codes, and ensuring no circuit breakers or isolators have tripped. If problems continue, our expert engineers are on hand to diagnose and fix the issue promptly.
Solar Panel Cleaning & Bird Protection
Rain washes off most surface dust, but it does not shift bird droppings, moss, lichen or the grime that builds along the bottom edge of each panel. Left alone, that soiling costs you output year after year.
Rather than sell every customer a cleaning visit, we start with an assessment. We check your generation figures against what the system should be producing, inspect the panels, and tell you straight whether cleaning solar panels will actually pay for itself on your roof. When it will, we clean them properly — purified water and soft brushes, never a pressure washer, which can damage panel seals and void warranties.
We also fit bird proofing mesh to stop pigeons nesting under the array — one of the most common causes of fouled panels and chewed cabling we see. Not sure what is safe to do yourself? Read our guide to cleaning solar panels.
Inverter Support & Lifespan Checks
Inverters generally have a lifespan of 10 to 15 years and are more susceptible to faults than solar panels. To help prolong their life, we perform thorough checks on ventilation to prevent overheating and assess dust build-up that can affect performance. We also carry out firmware updates and calibration routines to ensure optimal operation. Our team monitors manufacturer-specific error codes to detect issues early. If your inverter requires replacement, our inverter replacement service provides fast, efficient and compatible upgrades to minimise disruption and maintain your system’s energy output.

How often should I service my solar panels?
Once a year is right for most systems. An annual service catches faults early, keeps the inverter healthy and gives you a written record of how the system is performing, which is useful evidence if you ever need a warranty claim. Panels near trees, farms or busy roads may need cleaning more often.
Do you maintain systems installed by others?
Yes. Plenty of the firms that fitted solar in the 2010s are no longer trading, and we take over orphaned systems regularly. We survey what is there, put right anything unsafe, and from then on you have a local, MCS-certified company to call.
Can dirt or birds lower solar output?
Yes, both. Bird droppings, moss and grime shade the cells beneath them and drag generation down, and pigeons nesting under panels can damage cabling. Cleaning restores the lost output, and bird proofing mesh stops the nesting problem coming back.
What are signs my system needs servicing?
Generation noticeably below previous years, a red or flashing light on the inverter, an error code, or visible dirt, moss or bird activity on the array. A monitoring app that has stopped showing data is worth investigating too — start with our guide to testing a solar panel.
How long do solar inverters usually last?
Ten to fifteen years is normal for a string inverter, so most systems need a new one at some point during the panels’ life. Good ventilation and firmware updates help it along. When yours does fail, our solar inverter replacement service supplies and fits a supported replacement quickly.
Do you offer commercial solar servicing?
Yes. We service commercial arrays across the Midlands, from small office systems up to warehouse scale — including a 177kW system whose six original inverters we replaced in 2025. Planned maintenance keeps output up, downtime down and your compliance records straight.
What if I see a red light on my inverter?
Note the error code on the display and check whether any breakers or isolators have tripped. If the code is still there after a restart, send us a photo of the inverter and the code and we will diagnose it. Most faults are either fixable on site or a sign the unit has reached the end of its life.
