What reviewers say
Positive Energy Solutions
Customers consistently report smooth, transparent quotes backed by staff who explain options clearly and ensure federal and state rebates are claimed. Installers arrive on time, work cleanly, and walk owners through their new system-solar, battery, hot water, or EV charger-with professionalism and care. Follow-up calls and customised manuals are typical. Rare friction points are minor: one customer received generic post-install guidance rather than bespoke inverter settings, and stock shortages have occasionally meant second-day completions. Across 420 reviews, 97% are five-star.
Named staff like Maya, Louis, Madison, Adon, Dan, and Nathan crop up for their patient, jargon-free explanations and swift responses to questions. The company repeatedly honours original quote prices even when rebates drop or install dates slip. Reviewers note Positive Energy was stockable and responsive when other installers quoted months of delays. Systems range from modest 8.8 kW solar with 15–16 kWh battery to large 13.8 kW arrays with 54 kWh SigEnergy packs, with pricing reflecting rebates applied. One widowed customer remarked on the care and consideration shown; another praised handling a complex install with difficult cable routing.
Australis Solar
Installation runs smoothly from quote to handover for most customers, with crews managing complex multi-stage jobs and finishing clean. Staff including Luke, Guy Avery, and Boyd Winton earn consistent praise for responsiveness, knowledge, and integrity. Two significant exceptions stand out: one customer faced property damage (damaged render) that the owner refused to take responsibility for, and another lost a $2685 deposit without itemised costs after cancelling a month before scheduled work, a dispute now in Consumer Affairs.
The company serves repeat customers adding batteries to existing solar systems and handles integrated setups like EV chargers with Sigenergy batteries. Reviewers highlight the company's restraint in not upselling ("didn't push us like other companies") and willingness to problem-solve on site (creative pole placement, solar-only charging options). Work spans residential installs of 6.6 kW to larger commercial systems (22 kW panels, 15 kW inverters, 35 kWh battery storage).
Which should you pick?
Pick Positive Energy Solutions if
- You want a track record of honouring the original quote even if battery rebates shift or install dates slip
- You're after a large-capacity battery setup (30-50+ kWh) with proven installs at that scale
- You want the reassurance of a bigger, more consistent review base (420 reviews, 97% five-star)
Pick Australis Solar if
- You're adding a battery to an existing solar system and want an installer known for not upselling
- You need creative on-site problem-solving for tricky placement (poles, partial charging setups)
- You're comfortable with a smaller but still highly-rated track record and want to negotiate pricing directly upfront
Verdict
For battery storage specifically, fit comes down to how much weight you put on pricing certainty and scale versus a no-pressure sales approach. Positive Energy Solutions has the stronger paper trail for large batteries and a clear habit of protecting customers from rebate or scheduling changes, which counts for a lot given how often battery rebates move. Australis Solar is a solid pick if you're bolting a battery onto existing solar and want an installer that won't push you toward a bigger system than you need, but its unresolved damage and deposit disputes are worth weighing before you sign anything with a deposit attached.
