Every review praises James and the team for efficient, clean installation work on solar and battery systems across Perth Metro. James handles sales calls at weekends, answers follow-up questions days later, and returns same-day for support issues; Hayley coordinates quotes. Prices consistently rated competitive against other suppliers. One customer regretted not choosing a larger battery; otherwise no criticisms across 18 reviews. Installation teams work through difficult weather, reinstate roof tiles without leaks, and clean up after themselves. Backup power, inverters, and monitoring apps explained post-install. The business manages complicated jobs involving old-system removals and multi-month delays without friction. One weekend emergency (grid-side voltage alert) saw James lodge Western Power reports himself and follow up next day.

All 34 reviews are five-star. Reviewers consistently praise Mick and his team for arriving on schedule, communicating well, and delivering clean panels with visible before-and-after proof. Several customers report measurable energy gains after cleaning (up to 1.8 kWh daily), and many book repeat annual services. Pricing is noted as fair: $5 per panel with a $90 minimum, gutters around $200 for a three-bedroom home.

All five reviews from five years ago praise Heath's knowledge and straightforward approach. Customers value that he recommends what suits them rather than the priciest option, uses quality gear, and offers after-hours backup that rivals rarely match. Limited recent evidence.
