Responded quickly and were very engaging throughout. New roof and solar panels sorted in 5 working days. Approachable management and friendly team. Would use again.
Jim Cook
We had solar panels fitted by GLSR and the team were excellent, both in their approach to the job and in keeping me in the loop throughout the installation. They ran through the system with me and answered all of my questions. From start to finish, I couldn’t fault them.
Colin Judd
We had the hybris loft insulation. The free call helped to understand the situation in our loft. The fitters were friendly and the job was done efficiently. We can feel a difference within the air already, looking forward to more benefits.
Shanice M
We had spray foam in the house we wanted to purchase & the mortgage lender withheld the funds until removed. GLSR acted immediately. It was found that the roof required to be replaced due to its age. Works started within 48hrs and completed in 2.5 weeks & done to a high standard. Exceptional service & would highly recommend.

Common Solar Panel Problems We Repair
Solar PV systems are designed to provide reliable performance for many years, but faults can occasionally develop within the panels, inverter, wiring or other components. Our team can investigate problems with existing solar installations, identify the cause of poor performance and recommend the appropriate repair.
Solar Panel Fault Finding & Diagnostics
If your solar PV system has stopped generating electricity or its output has suddenly dropped, the first step is identifying exactly where the problem lies. A fault may be caused by the panels themselves, electrical connections, cabling, the inverter or another part of the system.
GLSR Solutions provides solar PV fault finding in Nottingham to investigate system problems and determine what is preventing your installation from operating correctly. Once the fault has been identified, we can explain the issue and recommend the most appropriate repair to help restore the system’s performance.
Key issues we can investigate:
- Solar panels not generating electricity
- Unexpected drops in system performance
- Solar PV system faults and warning messages
- Electrical and connection problems
- Problems affecting individual panels or the wider system


Solar Inverter Repairs & Faults
Damaged & Underperforming Solar Panels
Solar panels can continue generating electricity for many years, but damage or faults can result in individual panels or the overall system producing less energy than expected. If you have noticed a reduction in generation or believe that part of your solar array may not be working correctly, it is worth having the system investigated.
GLSR Solutions can assess underperforming solar PV systems in Nottingham to identify issues affecting their operation. We can check for problems with individual panels and associated system components, determine the likely cause of reduced performance and recommend the appropriate repair where required.
Problems we can investigate include:
- Solar panels producing less electricity than expected
- Individual panels not performing correctly
- Visible damage to solar panels
- Problems affecting connections or components
- Unexplained reductions in solar PV generation

Repairs for Existing Solar PV Systems
You don’t need to have had your solar panels installed by GLSR Solutions to use our repair service. If you have inherited a solar PV system with a property, your original installer is no longer available or you simply need help with an existing installation, our team can investigate the problem and advise on the work required.
Older solar PV systems can develop faults as components age, and it may not always be immediately obvious which part of the installation is causing the problem. We can assess the existing system, investigate issues affecting its operation and determine whether individual components can be repaired or need to be replaced.
Where possible, our focus is on finding a practical solution that allows you to continue using your existing solar installation. If you are considering a wider upgrade, you can also explore our solar panel installation services in Nottingham. We’ll explain what we’ve found and recommend the appropriate next steps to help restore reliable performance.

Signs Your Solar Panel System May Need Repair
Problems with a solar PV system aren’t always immediately obvious. In some cases, the first indication of a fault is an unexpected reduction in the amount of electricity being generated. You may also notice warning lights or error messages on your inverter, irregular system performance or periods where the system stops generating altogether.
If your solar panels are producing noticeably less electricity than they previously did, it is worth having the system investigated rather than assuming the reduction is normal. Identifying a fault early can help determine which part of the installation is causing the problem and what work is required to restore its performance.
GLSR Solutions can assess solar PV systems across Nottingham and diagnose issues affecting panels, inverters, connections and other components.
What Can Cause Solar PV System Faults?
A solar PV installation consists of several components working together, which means a loss of performance isn’t necessarily caused by the panels themselves. Inverter faults, electrical connections, damaged components and age-related deterioration can all affect how effectively a system operates.
Changes in system performance can also develop gradually, making faults difficult to recognise without comparing current generation with the system’s previous output. Our team can investigate the installation as a whole to establish where the problem originates rather than replacing components unnecessarily.
Once we’ve identified the cause, we’ll explain the issue and advise on the appropriate repair or replacement required to get the system working correctly again.

Getting Your Solar Panels Working Again
When a solar PV system develops a fault, the right solution will depend on the cause of the problem and the condition of the existing installation. Some issues may be resolved by repairing or replacing an individual component, while older systems may require more extensive work to restore reliable performance.
GLSR Solutions takes a fault-first approach to solar panel repairs in Nottingham. We assess the existing installation and investigate the panels, inverter and associated components to establish what is preventing the system from operating as expected. This helps us recommend the appropriate work rather than replacing parts without first understanding the underlying problem.
Where a component has failed and cannot be economically repaired, we can advise on suitable replacement options and explain how these can work with your existing solar PV installation. We can also advise on solar battery storage in Nottingham where you want to make greater use of the electricity your system generates. Our aim is to retain as much of the existing system as practical while restoring safe and effective operation.
Once the required work has been completed, the system can be checked to ensure it is operating correctly. We’ll also explain the work carried out and any further recommendations for your installation, giving you a clear understanding of the condition of your solar PV system.

FAQs
Common signs of a problem include a sudden or unexplained drop in electricity generation, inverter warning lights or error codes, the system repeatedly shutting down or your solar panels stopping generation altogether. Some faults are less obvious, so if your system is consistently producing less electricity than you would normally expect, it may be worth having it investigated.
Yes. You don’t need to have had your solar panels installed by GLSR Solutions to use our repair service. We can investigate faults with existing solar PV systems, including installations where the original installer is no longer available or where you have inherited the system after moving into a property.
There are several reasons why a solar PV system may stop generating. The problem could relate to the inverter, electrical connections, individual panels or another component within the installation. Professional fault finding allows us to identify where the problem originates before recommending the appropriate repair.
This depends on the type of inverter, the fault and the age and condition of the equipment. Some inverter problems may be repairable, while others may require replacement. GLSR Solutions can investigate inverter faults and advise whether repair or replacement is the most appropriate option for your existing solar PV system.
In many cases, yes. A fault with one component doesn’t necessarily mean the entire solar PV system needs replacing. We can assess the existing installation, identify the cause of the problem and determine whether repairing or replacing individual components could restore the system’s performance.
