Professional Care for Your Solar PV System

Your solar panels and inverter are built to last decades - but like any critical system, they perform best with regular care. We offer planned maintenance and on-demand repair for domestic and commercial solar PV installations across London. From annual health checks and technical performance audits to inverter diagnostics and fault finding, we keep your system safe, efficient and within warranty. Done once, done right - and kept that way.

What We Offer

Annual solar PV inspection on London roof — MCS maintenance visit and inverter checks electricalworks Commercial flat-roof solar maintenance — array inspection and electrical testing South London MCS electrician

Annual Inspections

A thorough year-round health check covering every layer of your solar PV system. We log readings, flag wear before it becomes failure, and keep your installation within manufacturer warranty requirements.

  • Visual check of mounting, cabling and roof penetration integrity.
  • Isolator, junction box and connector torque verification.
  • Inverter performance data review and firmware check.

Fault Finding & Repair

No generation, tripping or odd readings? We use systematic diagnostics to trace faults at panel, string and inverter level, then restore full output with a single visit wherever possible.

  • DC string testing and earth fault location.
  • Inverter error-code diagnosis and component replacement.
  • Rapid re-commissioning with post-repair yield verification.

Why Regular Maintenance Matters

Solar PV systems have few moving parts, but they are exposed to weather, UV and dirt. Annual inspections help catch loose connections, shading from growth or damage before they affect yield or safety. Many manufacturer warranties also require evidence of periodic maintenance. We provide clear reports you can keep for your records and for warranty or insurance purposes.

Whether your system was installed by us or another MCS-accredited installer, we can look after it. We work on all major brands of panels and inverters (SolarEdge, Fronius, Huawei, GivEnergy, Tesla and more) and will always recommend repair over replacement where it makes sense.
