What reviewers say
Positive Energy Solutions
Positive Energy Solutions delivers rapid, professional installations backed by strong customer support for most clients. However, two recent reviews flag serious gaps: one buyer's battery location was approved by management but rejected on install day, another received undersized panels and experienced unresolved electrical faults and compliance issues flagged by Western Power. Follow-up communication has been inconsistent when problems arise.
The business handles residential solar, batteries, hot water, and EV chargers across Perth Metropolitan. Their website lists bundle prices from $14,990 to $38,140 (after rebates) and claims SolarQuotes number-one installer status in WA and SunWiz battery rankings. Most reviewers praise the Sigenergy and iStore battery systems and note grid consumption drops of 90%+ once systems run. The tension between fast sales processing and installation accountability remains the unresolved pain point.
Australis Solar
Australis Solar earns consistent five-star feedback for their design expertise and installation quality. Boyd, the team, and the team are named for professionalism; teams clean up daily and work efficiently. Reviewers value their patience through complex builds (28.42kW systems, EV chargers, smart home integration) and transparent pricing.
Two serious complaints stand out: a $2,685 deposit held after cancellation without itemised cost evidence, and a ladder damaging house render with owner refusal to accept responsibility. One reviewer also flagged safety concerns at heights. These breach the fair treatment reviewers otherwise praise.
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.
