Solar not generating like it used to? We can fix that.
Inverter faults, dead strings, failed isolators, monitoring that's gone silent — most older solar systems just need a competent visit, not a full rebuild. We work on systems we didn't originally fit.
Common solar problems — and what they actually mean.
Generation has dropped
Often a failed bypass diode in one panel, a dead string, or a tired inverter. We measure first and quote second.
Inverter showing fault codes
Most string inverters fail somewhere between year 10 and 15. Replacement is straightforward; we'll match capacity and warranty terms.
Monitoring app has gone dark
Sometimes a router change knocks the inverter off the network; sometimes it's a comms board failure. We diagnose on-site.
Birds nesting under panels
We clear them out and fit bird mesh / pigeon guard to the whole array. Surprisingly common, surprisingly satisfying job.
Failed isolators or wiring
Older rooftop DC isolators are a known weak point. We replace with current-spec, sealed units.
Original installer gone
We take over orphan systems, work out what's there, and either bring it back to life or quote honestly for a rebuild.
Repairs & servicing — frequently asked
Yes — most of our repair work is on systems we didn't originally install. We can diagnose inverter faults, replace failed components, recommission systems and bring older arrays back up to spec.
Yes — this is common, especially with installers who set up around 2010–2014 during the Feed-in-Tariff boom. Bring us whatever paperwork you have and we'll work out what you've got and what needs doing.
A typical domestic string inverter swap is £1,200–£2,200 fitted, depending on size and the brand. We'll always quote up-front after a diagnostic visit.
