Solar repairs & servicing in Pakenham & Cardinia.

The corridor’s ageing solar base.

Pakenham and Cardinia have a decade of estate solar on their roofs, and a lot of it is now 10–15 years old — the age where inverters fail, isolators degrade and output quietly drops. Many of those original installers have gone out of business. We service and repair any brand regardless of who installed it, so a dead system isn’t a write-off just because the warranty company vanished.

What we diagnose & fix.

• Inverter faults — error codes, no display, red lights, repair or replacement
• Underperforming systems — output lower than it should be, more grid import than expected
• Isolator & fuse issues — the known failure point on older rooftop and meter-box isolators
• Meter & grid-voltage problems — tripping, export not registering, voltage-rise shutdowns
• Panel & string testing — identifying dead panels, shading losses and soiling, plus a clean

How a service call works.

A diagnostic call-out and health check is typically $150–$250, credited toward the repair if you proceed. We test panels and strings, read the inverter, check isolators and the meter, and quote the fix before any chargeable work. Common repairs: isolator or fuse replacement $200–$450; inverter replacement $1,500–$3,000 depending on size and brand; panel clean and string test from around $200. We’ll tell you honestly when an ageing inverter is better replaced than repaired.

Servicing & pre-sale checks.

A health check every 2–3 years keeps a grid-tied system honest, and a pre-sale check turns your solar into a selling point for buyers. All work is to AS/NZS 5033 and AS/NZS 4777 by a CEC-accredited installer, with a Certificate of Electrical Safety where prescribed.
