Solar Panel Maintenance
A solar PV system is a long-term investment and like any investment, it performs best when it's looked after. At Green Flare, we keep solar panels across Bristol working at peak efficiency with expert servicing, performance checks and repairs.
With more than three decades of combined experience designing and installing renewable energy systems, our MCS-accredited engineers know exactly what to look for. Whether your system was installed by us or another company, we'll make sure it's safe, efficient and generating every kilowatt it should be.
Why Solar Panel Maintenance Matters
Solar panels are designed to be low-maintenance, but they aren't no-maintenance. Over time, dirt, moss, bird fouling and debris reduce output, while electrical components, inverters and connections can degrade or develop faults that often go unnoticed until your generation drops or your system stops exporting altogether. An annual service protects your investment and your warranties:
1. Maximise generation
Restores lost output caused by soiling, shading and faults.
2. Prevent costly repairs
Catches loose connections, water ingress and inverter issues before they become expensive failures.
3. Protect your warranty
Many manufacturer warranties require evidence of regular servicing by a qualified engineer.
4. Keep your system safe
Faulty isolators and degraded cabling are a genuine fire and electrical risk.
5. Extend system life
A well-maintained system lasts longer and delivers a better return over its lifetime.

Gareth Nettleton
"I cannot speak highly enough of the service received from Green Flare for the installation of solar panels on our roof. Aaron and Alex (the install team) were fantastic. The work quality looks great, they were polite and accommodating while on site, and completed the project in double quick time. Would thoroughly recommend Green Flare for their professionalism and service."
David Lowe
"Selecting a solar panel installer is a bit of a minefield - I met several before spotting a Green Flare van in our village an asking for a quote - I had very specific ideas about the sighting and visual impact of my installation and the Green Flare team worked hard to accommodate my requirements - The installation team were helpful and efficient and I am delighted with the finished product."
Martin Mullen
"Having been let down by the company who installed my solar panels, Green Flare stepped in and provided an excellent service. They even dealt with the damage caused by the scaffolders. Their staff were first class, professional and polite. I would have no hesitation in recommending this company."
Helen Newton
"Fantastic experience. We had PV and two batteries installed, as well as an EV charger and Myenergi Eddi (for heating water tank). We've not had it long so can't review the items but our experience with the entire Green Flare team from start to finish was great. From the initial quote, to the follow up information, right through to the installation team - all were professional and polite and did a great job."
James Young
"Very happy with the solar panel system and would highly recommend Green Flare to anyone looking for a PV install. Installers were friendly and professional. So far the system is out performing the original estimates so could not be happier."
