Solar Dimension
Owner-designed system quotes, named crews who explain every step, and a track record of multi-stage battery upgrades across Cairns and Townsville.
Owner Zoe is directly involved in consultations rather than delegating to junior sales staff, and several customers specifically mention that her willingness to customise system size and stage upgrades over time made the difference in choosing Solar Dimension over cheaper competitors. The one pattern worth raising before you sign: four separate reviewers describe poor responsiveness when seeking warranty repairs or fault resolution after installation — a meaningful enough cluster (roughly 8% of the sample) to ask directly about their warranty service process and typical response times before committing. That said, a separate review notes the team stepped in when a manufacturer was unresponsive, so the picture isn't uniform. Before signing, it's worth asking: who is your point of contact if something goes wrong six months post-install, and what is the typical turnaround for a service call?

About Solar Dimension
Solar Dimension is a Cairns-Townsville region solar company specialising in residential solar panel and battery storage systems, including large-scale setups like 48kWh battery banks and 30kW battery additions for existing systems. Owner Zoe handles consultations personally and is praised across multiple reviews for customising system designs to actual household usage rather than pushing standard packages — she's also the one who goes beyond the sale, helping one rural customer find a roofing contractor and troubleshoot mains issues before installation could proceed. On the sales side, Bree and David handle initial consultations and drone-based roof assessments, while Vu Tran is called out for detailed system design work and staying available through post-install questions. Installation is split across several crews: Darren leads battery installs with a reputation for meticulous work that impressed even a self-described OCD customer; Adam's crew is repeatedly named for switchboard upgrades, GPO relocations, and thorough system handovers; Nick's team is praised for speed and tidiness on panel-heavy jobs. The business suits homeowners who want to understand what they're buying — multiple reviews specifically mention the team explaining app usage, startup/shutdown procedures, and tariff arrangements — and it's a natural fit for staged solar projects where a battery is added months or years after the original panels.
Best for: homeowners wanting a custom-designed solar-plus-battery system, staged upgrades where a battery is added to existing panels, and customers who want a thorough handover and system explanation on installation day.

What areas does Solar Dimension service?+
Solar Dimension is based in Currajong and reviews confirm installations across Cairns, Townsville, and surrounding rural areas — one reviewer mentions a remote bush property where Zoe helped coordinate additional trades to make the install possible. If you're outside the main Cairns-Townsville corridor, it's worth calling to confirm coverage and whether travel costs apply, particularly for multi-day rural jobs.
Can Solar Dimension add a battery to my existing solar system?+
Yes — battery retrofits to existing solar systems are a clear specialty based on the reviews. Multiple customers describe adding batteries months or years after their original panel install, including a 30kW battery added 18 months post-install and a second 9.6kWh battery added roughly 15 months after the first. The team also handles the switchboard work required to integrate battery backup, including EPS switch installation.
What do customers say about Solar Dimension's pricing?+
Pricing is described as competitive across multiple reviews, with several customers noting Solar Dimension matched or beat other local quotes while offering more detailed information in their proposals. A few reviewers specifically mention getting multiple quotes before choosing Solar Dimension based on the combination of price and communication quality rather than price alone. Finance options are also mentioned by one reviewer whose weekly repayments came in below their previous power bill.
What should I know about Solar Dimension's after-sales warranty service?+
This is worth discussing before you sign. Four separate reviews in the sample describe difficulty getting a timely response when their system developed a fault post-installation — in two cases, customers ended up using a different company to carry out repairs. On the other side, at least one reviewer notes that Solar Dimension stepped in to help when the manufacturer was unresponsive. Before committing, ask specifically who your point of contact is for warranty claims and what the typical service call turnaround time looks like.
How long does a typical Solar Dimension installation take?+
Most residential installs described in reviews are completed in a single day, with several reviewers noting the job finished faster than they expected. Larger jobs involving battery storage, switchboard upgrades, and panel arrays can run across two days. The installation crews — Adam's, Darren's, and Nick's teams are the most frequently mentioned — are consistently praised for turning up on time and finishing efficiently without cutting corners on explanation or cleanup.
