What recent reviews say

Installation often happens quickly and smoothly, but after-sales support is unreliable. Panels may arrive loose or misaligned, and getting help when systems underperform is difficult; support staff take weeks to reply or pass problems back to manufacturers overseas.

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

Recent shift: negative trend: the most recent reviews (2 years ago) contain the harshest complaints about non-responsive support and installation defects, whereas the oldest cohort (3 years ago) included more positive experiences and named staff praise

Praised for
  • professional installation team
  • zero bill guarantee appeal
  • good value for the price
  • courteous staff and follow-up from management
Watch-outs
  • poor after-sales support and slow response times
  • installation quality issues (loose panels, mismatched equipment, faulty fitments)
  • warranty claims handled offshore with poor communication
  • system performance falls short of promises
reliable-installationmessy-workmanshipno-follow-up-supportslow-responsehonest-advice
Best for: buyers prioritizing fast installation and willing to troubleshoot independently if issues arise
Think twice if: your priority is ongoing support and quick follow-up when systems underperform or develop faults

Strengths

  • quick installation turnaround
  • named staff (Carl, Goodie, Jerry) praised for professionalism
  • zero bill guarantee marketing

Worth knowing

  • Carl manages the installation team at Bibra Lake
  • Jerry Zhu is Operations Manager who conducts follow-up visits
  • Growatt inverters mentioned in reviews with intermittent failures and slow warranty replacements
  • panels sometimes installed loose or misaligned requiring return visits
  • support handled through overseas call centres with documented delays (10+ days to respond to emails)

Common questions

How long does installation take?
One reviewer noted their 8kw system was installed in half a day. However, another customer experienced an almost 2-month delay from the initial quoted timeframe.
What happens if my system isn't working as promised?
Support is available via phone and email, but response times are slow (10+ days reported for email replies). Support staff may ask you to troubleshoot remotely or suggest resetting equipment temporarily rather than arranging technician visits.
Do you offer a performance guarantee?
The business markets a zero bill guarantee, but multiple reviews report electricity bills remained unchanged or increased after installation, with support dismissing concerns.

Installation teams arrive on schedule and leave no mess; reviewers consistently praise neat cabling, removed waste, and polished finishes on solar and battery setups across Perth suburbs. Umair and his crew handle end-to-end process from remote roof assessment through rebate paperwork, answer questions plainly, stick to quoted timelines, and charge less than ten other quotes reviewers collected. Several customers have already referred friends and family, signalling trust in repeat execution.

Most customers praise Jacob and the team for knowledgeable, efficient installation work on CCTV and security systems, with fair pricing and thorough after-sales guidance. Professional finish and punctual service stand out as consistent strengths. However, a small number report significant issues: incomplete installations with missed components, long delays responding to service requests, and one customer faced aggressive upsells totalling $1700 with the original job later left unfinished. These complaints centre on follow-through and accountability rather than workmanship quality.
