Replenishable Energy
Rollo designs the system himself — customers mention him by name for adapting quotes to unusual setups and tight budgets.
From the 50 reviews we analysed, not a single one raised a complaint about workmanship, delays, or hidden costs — the sole negative in the sample was a prospective customer who felt the quoting process didn't suit their particular existing system, which is useful context if you're looking to retrofit batteries onto a non-Replenishable installation. The business has done work ranging from single residential rooftops through to 36-unit and 96-unit commercial complexes, so if you have a non-standard property or a complex three-phase setup, it's worth asking Rollo specifically during the consultation rather than assuming a standard residential quote will cover it.

About Replenishable Energy
Owner Rollo leads this Cairns-based solar company, handling system design consultations and site assessments himself — reviewers specifically credit him for tailoring configurations to unusual setups like three-phase requirements, large commercial-scale shed installations, and off-grid battery arrangements rather than pushing a one-size package. Daniel anchors the sales and after-sales side, with multiple customers noting he answers queries over weekends and on Christmas Eve, and kept communication flowing between quote and handover without prompting. The installation crews — teams led by Pietro, Danillo, and Paul are mentioned by name — are consistently noted for finishing in compressed timeframes (some full solar-plus-battery systems completed in a single day or two), leaving sites spotless, and walking homeowners through every component before packing up. The business handles residential solar panels, battery storage (Tesla Powerwall, Sungrow, FoxESS), EV chargers, and system upgrades including integrating new batteries into existing third-party solar arrays — a broader scope than many installers who only commission new builds. With roughly 15 years in the market and experience across individual homes, multi-unit accommodation complexes, and body corporate common areas, this is a company suited to homeowners who want a technically detailed consultation rather than a quick templated quote.
Best for: homeowners wanting a fully integrated solar-plus-battery-plus-EV-charger system, non-standard or three-phase residential setups that need custom design, customers who value direct access to the owner during consultation, and commercial or multi-unit property managers coordinating large-scale installations.

What areas does Replenishable Energy service?+
The business is based in the Cairns region and reviewers mention installations in Palm Cove, Atherton, and surrounding areas, suggesting they cover a reasonably wide radius across Far North Queensland. Several customers reference driving or coordinating with the team for properties outside central Cairns. If you're in a more remote part of the region, it's worth confirming serviceability directly with Rollo before requesting a quote.
Does Replenishable Energy install battery systems alongside solar, or solar only?+
Battery storage is a significant part of what they do — reviewers mention Tesla Powerwall, Sungrow batteries (including a 50kWh system), and FoxESS battery installs alongside solar panels. Several customers had combined solar-plus-battery-plus-EV-charger setups completed in a single visit or over two days. They have also retrofitted batteries onto existing solar systems, though one reviewer noted their quote process didn't suit adding batteries to an older third-party system, so it's worth discussing your existing setup upfront.
How does the quoting process work and will I get options or just one price?+
Multiple reviewers specifically mention receiving two or more system options at different price points during the quoting stage, rather than a single take-it-or-leave-it proposal. Rollo typically handles initial consultations and system design, and Daniel manages quote follow-up. Customers report having time to compare with other providers without being pressured, and several note the technical explanations were clear even for people who described themselves as not tech-savvy.
How long does installation typically take?+
Based on reviews, most residential solar and battery installs are completed in one to two days. A 20kW shed system and a combined solar-battery-EV-charger setup were both cited as two-day jobs, and some smaller residential systems were done in a single day. Customers consistently report the crew arriving on the confirmed date rather than receiving last-minute notice, and Ergon pre-approval is handled by the business ahead of install day.
What kind of after-sales support can I expect once the system is installed?+
Post-installation responsiveness is one of the most frequently mentioned strengths across the 50 reviews we reviewed. Daniel is specifically credited for answering queries over weekends and on Christmas Eve, and one customer noted a firmware issue was resolved within 20 minutes of a late Friday night call. Several long-term customers note the team remained responsive years after installation. The business also provides a full installation report and manual, sets up Wi-Fi monitoring before leaving, and conducts follow-up calls to confirm the system is running correctly.
