Solar · Repairs & upgrades
Solar repairs and upgrades in Valencia — diagnosed by instruments, revived properly.
A dead inverter, a lazy string, an installer who vanished: repairs from €140 on any brand — measured to the cause, fixed or upgraded with the economics in writing.
In plain terms
Solar rarely dies. Mostly it waits for attention.
Half of Valencia's underperforming arrays trace to one fixable culprit: a connector cooked in year six, an optimiser down, an inverter fault nobody read. We measure string by string until the cause has a name — then repair, or upgrade where a decade has simply passed.

How it works
From symptom to restored yield.
Describe it
Symptoms, app screenshots, history — by message.
Instrumented visit
Strings, inverter and insulation measured.
Written verdict
Cause, options and prices — before work.

Fixed, re-measured, documented.
The price
Honest triage, then the fix.
€140 for the instrumented diagnosis, credited against the repair. Where upgrade beats repair, you'll see both columns — and decide on numbers.
- String and inverter measurements
- Insulation and connector checks
- Written verdict with options

Questions, answered
Asked before hiring us.
What does a solar repair cost?
Diagnosis is €140, credited against the repair you approve. Connector and wiring repairs commonly land €150–€400; inverter matters are quoted per verdict — always in writing first.
My installer disappeared — can you service the system?
Yes — orphaned systems are a third of our solar work. Any brand: we read the system, build its baseline, and it has a responsible team again.
The inverter shows an error code — is it dead?
Often not: many codes are grid-setting or insulation matters, fixable in one visit. Send the code by message — we usually arrive knowing the likely story.
Is my 10-year-old system worth upgrading?
Frequently — panels may be fine while the inverter generation holds them back. The diagnosis prices repair against a hybrid upgrade honestly; batteries often tip the maths.
Do you handle warranty claims?
Where measurements show a manufacturer fault, we document it to warranty standard and manage the claim — that's what the IV curves are for.
