G-Solar & Electrical
Tesla Premium Installer accreditation sets them apart for Powerwall upgrades that most Far North QLD solar companies can't authorise.
That end-to-end coherence is the thing most likely to matter if your job involves a complex system or a remote property. Their Tesla Premium Installer accreditation is verifiable and meaningful: it means they can handle Powerwall replacements and expansions that most local solar companies simply aren't authorised to touch. Multiple reviewers also flag that G-Solar pushed back on oversized system recommendations from other providers and quoted them something smaller and better matched — worth keeping in mind if you've already had quotes that felt inflated. One review in the sample describes a rushed battery replacement that left the home without power before a follow-up technician resolved it; this appears to be an isolated incident in a pool of 327 reviews, and the same reviewer updated their rating after the remediation, but it's worth asking the team to confirm their sign-off and testing procedure before the crew leaves your property.

About G-Solar & Electrical
G-Solar & Electrical are Tesla Premium Installers — one of a select group authorised to handle Tesla Powerwall upgrades and replacements — which sets them apart from most solar companies operating in Far North Queensland. Their work spans solar-only installs, battery retrofits to existing systems, EV charger additions, and full system replacements, with documented jobs ranging from modest residential upgrades to a 19.8kW panel array paired with 27kW of Tesla battery storage. The office team has a clear division of labour that customers notice: Alexis Rogato handles business-level planning and quoting, Mark and Grant cover on-site consultations and system design advice, Helen and Lauren manage administration and keep customers updated through every stage, while Daniel coordinates installation scheduling. On the tools, named installers like Anthony, Steve, Bryson, and Josh are repeatedly praised for precise, clean workmanship — several reviews specifically call out how tidy the cabling and wall-mount work looks. A recurring detail across reviews is that G-Solar actively avoids overselling: multiple customers note they were talked out of oversized systems and steered toward what actually suited their usage, which is the kind of candour that earns referrals. They cover a genuinely large geographic footprint — installations are mentioned in Cooktown, Daintree, Mossman, and Cairns — making them one of the few operators willing to travel to remote Far North Queensland properties.
Best for: Tesla Powerwall upgrades and replacements requiring Premium Installer authorisation, large residential solar-plus-battery systems in the Cairns region, homeowners in remote Far North QLD locations other installers won't service, and customers replacing outdated systems who want honest advice on right-sized equipment.

What geographic area does G-Solar & Electrical cover?+
Based on reviews, G-Solar covers a wide stretch of Far North Queensland — customers mention completed jobs in Cairns, Cooktown, Daintree, and Mossman, with one reviewer specifically noting they are the go-to for anyone between Cairns and Mossman. If you're in a remote or regional area that other solar companies won't travel to, it's worth calling to confirm they can reach your property. Their willingness to travel for complex installs in challenging locations is a recurring theme across the reviews we analysed.
Is G-Solar & Electrical authorised to install and upgrade Tesla Powerwall batteries?+
Yes — G-Solar holds Tesla Premium Installer status, which means they are specifically authorised to handle Powerwall installations, replacements, and upgrades. One detailed review describes a full upgrade from a Powerwall 2 to a Powerwall 3 with expansion pack (27kW total storage) completed in March 2026. This accreditation is meaningful because many local solar companies are not authorised to work on Tesla batteries at all. If you have an existing Tesla system needing service or expansion, this is one of the few local operators equipped to do it.
What do customers say about G-Solar's pricing and whether they push oversized systems?+
Multiple reviewers — including one who got six-plus quotes before choosing G-Solar — specifically note that Grant and the team steered them toward a system matched to their actual usage rather than the largest possible sale. One customer mentioned that AI research flagged G-Solar as a quality-first option, and when they contacted the company, the advice matched. Reviews don't include specific dollar figures, so you'll need a quote for your property, but the pattern of not upselling is consistent enough across the sample to be a genuine characteristic of how they operate.
Which team members are likely to be involved in my project?+
Based on reviews, the process typically involves Alexis Rogato (Business Manager) for quotes and initial planning, with Helen or Lauren in administration keeping you updated through scheduling and pre-install stages. Grant or Mark typically handle site consultations and system design. On installation day, named technicians include Anthony, Steve, Josh, Bryson, Carmelo, and Chris — all mentioned by name in positive reviews for professional workmanship and clear handover explanations. Daniel is cited as Installation Manager coordinating the on-site schedule.
How long does the installation process typically take from quote to completion?+
Reviews don't give a precise average timeline, but several customers mention the process moved faster than expected — one noted the system was on the roof less than a week after Grant's site inspection, and another said the job was completed ahead of schedule. G-Solar appears to communicate proactively via email and SMS at each stage, so you'll have visibility on timing rather than chasing updates. For complex installs (large battery systems, remote locations, or full system replacements), the planning stage naturally takes longer, but the install day itself is commonly completed within a single day based on review accounts.
