What reviewers say
Positive Energy Solutions
Sales consultants here respond quickly to enquiries and explain options clearly; most installations run on schedule, finish neat, and include thorough app walkthroughs. Named staff like Olivia, Mark, Maya Sinclair, Louis, and Madison stand out for patience and detailed guidance. Stock availability and quick turnaround set them apart during rebate deadlines.
However, one significant complaint alleges undersized installation (6.6kW delivered instead of 8.8kW paid for), delayed fault resolution (electrical and blackout backup issues unresolved for weeks), pushback on warranty claims, and a Western Power audit noting 11 compliance breaches. Most reviews praise the service model; this outlier suggests quality control and follow-through can fail on complex jobs.
Australis Solar
Australis Solar earns strong trust through knowledgeable staff who listen to customer needs rather than push sales, paired with installation teams that show up on time and leave sites clean. Equipment quality (Trina panels, Sigenergy batteries and chargers) is frequently praised, and communication stays responsive after the job ends.
Two serious issues stand out: one customer faced property damage (rendered wall) the installer refused to repair, and another lost a $2685 deposit over a cancelled install, with the company ignoring requests for cost breakdown. Both suggest inconsistent handling of problems, though the majority of installs run smoothly.
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.
