What an extended workmanship warranty covers
A standard manufacturer panel warranty protects the product itself against defects in materials or performance. An extended workmanship warranty goes further, covering the quality of the installation — mounting structures, electrical wiring, inverter commissioning and the integration of battery or EV‑charger hardware. It addresses the craftsmanship that determines long‑term system reliability, not just the hardware specifications.
Why it matters beyond manufacturer guarantees
Even premium panels can under‑perform if they are poorly secured, incorrectly wired or commissioned without the proper settings. Installation errors can lead to water ingress, voltage drops, premature inverter failure or reduced energy yield. An extended workmanship warranty transfers the risk of those installation‑related issues from the homeowner to the installer, providing a clear route to remediation without disputing product‑level claims.
Pier Solar’s craftsmanship‑over‑price philosophy
Pier Solar designs each system bespoke, specifying premium panels, inverters and storage that match the site’s orientation, shading profile and load pattern. The same rigour applies to the installation phase: every partner in our national network is MCS‑certified and vetted for consistent workmanship standards. The extended warranty is a natural extension of that philosophy — it signals confidence in the quality of the install, not just the spec sheet.
How the warranty works with our installation partners
When a project is commissioned, the appointed partner registers the installation under the extended workmanship scheme. The warranty covers labour and materials required to rectify any installation‑related fault for the agreed term. Claims are managed directly between the homeowner and the partner, with Pier Solar overseeing compliance and ensuring the original design intent is honoured throughout the warranty period.
