System health check & repair

A system that generates less than it used to, an inverter showing a fault, a panel cracked in a storm: a health check finds the cause before anyone replaces anything. We compare the system's output with the PVGIS figure for its orientation, test the strings and the inverter, and look at the mounting.

Repairs are carried out by a CheckYourTraders-verified solar installer and managed by us. If the inverter is at the end of its life, we will tell you whether a hybrid replacement makes sense.

What this covers

• Output compared with the expected yield
• Inverter, string and connector testing
• Panel, frame and mounting inspection
• Repair or replacement of faulty parts, quoted before work starts

What it costs

Diagnosis and repair are quoted per visit. We have no published Maltese rate to cite.

None of these has a published Maltese installed price we can stand behind, so each is quoted after the roof survey, itemised, before anything is ordered.

How it works

You deal with us, not with the installer. We survey the roof, quote a fixed price, bring in a solar installer from the CheckYourTraders-verified network, and stand behind the work. One point of contact, one contract, one invoice.
