What reviewers think

Strong installation quality and fair pricing win consistently on the early years, but poor after-sales support emerges as a pattern: customers struggle to reach the business for faults, inverter problems go unresolved, and warranty claims are rejected. Recent reviews show communication issues persist.

Based on limited recent reviews, so treat this as low-confidence.

Sales consultants here respond quickly to enquiries and explain options clearly; most installations run on schedule, finish neat, and include thorough app walkthroughs. Named staff like Olivia, Mark, Maya Sinclair, Louis, and Madison stand out for patience and detailed guidance. Stock availability and quick turnaround set them apart during rebate deadlines. However, one significant complaint alleges undersized installation (6.6kW delivered instead of 8.8kW paid for), delayed fault resolution (electrical and blackout backup issues unresolved for weeks), pushback on warranty claims, and a Western Power audit noting 11 compliance breaches. Most reviews praise the service model; this outlier suggests quality control and follow-through can fail on complex jobs.
