Expert diagnosis and repair of solar PV systems across Essex, Suffolk, Norfolk and Kent. If your system isn't generating what it should, we'll find out why — and fix it.
Solar PV faults are often gradual — output drops slowly enough that homeowners don't notice until they check monitoring data or see their energy bills creeping up. By the time a fault is identified, months of lost generation may have already occurred.
We carry specialist testing equipment and are experienced across all major inverter brands including SolarEdge, SMA, Fronius, Fox ESS, Solis, Solax, Sofar, Enphase and Tesla. Most faults can be diagnosed and resolved in a single visit.
We also work on systems we didn't install — from any manufacturer, any era, any configuration.
Where monitoring data is available, we review historical generation against expected output to identify when the underperformance started and narrow down likely causes.
Full inspection of panels, mounting, wiring, isolators, inverter, battery systems and consumer unit connections — looking for obvious faults, damage or deterioration.
DC and AC testing including string voltages, Voc, Isc, insulation resistance, inverter diagnostics and battery health checks where applicable.
A clear written report explaining exactly what was found and a fixed-price quote for any repair works. You decide whether to proceed — no pressure.
Experienced across all major inverter and battery brands — most faults diagnosed and resolved in a single visit.
The most common cause of total or significant output loss. We diagnose and repair or replace inverters across all major brands.
Loose or corroded DC connections cause arc faults — a serious fire risk. We locate and fully remediate all DC wiring issues.
Individual panel failure or accelerated degradation reduces string output. We identify underperforming panels using IV curve tracing and specialist equipment.
Battery management system errors, degraded cells or communication failures between battery and inverter — diagnosed and resolved across all major battery brands.
New obstructions, overgrown trees or panel soiling can significantly reduce output. We model shading impact and recommend the right solution.
Wi-Fi, data logger and portal connectivity faults leave you blind to your system's performance. We restore monitoring across all platforms.
The more detail you give us, the better prepared we'll be. In some cases we can give initial guidance before we even visit. Takes under 2 minutes.
We'll look over your answers and come back with initial thoughts and a diagnostic visit quote — usually within one business day. In some cases we may be able to help remotely first.
