Common solar faults we put right
The single most common reason a solar system stops generating is the inverter. As the only major electronic component, it works hard every day and typically needs replacing once during the life of an installation. Beyond that we frequently deal with tripped DC isolators, failed optimisers, corroded or water-damaged connectors, panels cracked by storm debris, and the loss of generation caused by pigeons nesting in the gap beneath the array. Whatever the symptom, our first job is to find the genuine root cause rather than simply swapping parts.
Our diagnostic process
We start by reviewing your monitoring data and inverter logs, which often point straight to the problem. On site we use thermal imaging to reveal hotspots and failing cells, and IV-curve tracing to test the electrical performance of each string against its specification. This methodical approach means we can tell you exactly what has failed, why, and whether it is covered by an existing warranty before you commit to any spend.
Repairs, replacements and upgrades
Many faults are resolved in a single visit, particularly inverter and isolator failures where we carry common units in stock. Where a panel has failed we source a compatible replacement; if your original panels are obsolete we will advise on the best modern equivalent. Older systems running first-generation inverters are often good candidates for an upgrade to a modern hybrid unit, which both restores reliability and makes the system ready for battery storage.
Bird-proofing and storm damage
The North East gets its share of strong coastal winds, and we regularly attend properties where flashing has lifted or debris has struck a panel. We also fit mesh bird-proofing around the perimeter of arrays to keep pigeons out, which protects both your generation and your roof from the mess and damage nesting causes. All repairs are tested and documented before we leave.
Why choose a local Sunderland team
As a genuinely local company we cover the whole of Sunderland and Wearside — from Roker, Seaburn and Fulwell on the coast to Washington, Houghton-le-Spring and the former pit villages inland. Because our engineers are directly employed rather than subcontracted, the same trusted team that quotes your solar panel repairs carries it out and looks after you afterwards. That local presence means faster appointments, quicker aftercare and advice grounded in real experience of North East homes, businesses and weather.
How the process works
Everything starts with a free, no-obligation survey at a time that suits you. We assess your property, talk through your goals and budget, and then provide a clear, itemised quotation with no hidden extras and no pressure. Once you are happy to proceed we handle every detail — design, any notifications to your network operator, the installation itself and full certification — before walking you through your new system and handing over complete documentation. Our relationship does not end there: we remain on hand for servicing, monitoring and support for years to come.
Accreditations, warranties and finance
We are fully MCS and RECC certified, so our work qualifies for the Smart Export Guarantee and any grant support available, and is carried out to recognised industry standards. We fit only quality, well-supported equipment backed by substantial manufacturer warranties and our own workmanship guarantee, and we can spread the cost through flexible finance options including interest-free packages on selected work. Whatever your circumstances, we will set out the figures transparently so you can make a confident, informed decision.
