What Six Star Plus does
Six Star Plus is a privately-held Melbourne-based installer and supplier of solar PV systems, battery storage, EV chargers, heat pump and gas hot water systems, and heating and cooling equipment, operating primarily in Victoria, Australia with 11-50 employees and 15+ years of operating history. The company serves two primary customer segments: homeowners (B2C) acquired through a structured online quote funnel, website content, referral program, and community engagement; and residential builders (B2B) via a network of 17+ named builder partners including HIA, Master Builders Victoria, SJD Homes, Kingsbridge Homes, Martin Builders, Forme Homes, and Nostra Homes. The business operates a sales-led go-to-market model supported by dedicated account management for builder partners.
The company's product portfolio spans multiple premium brands — GoodWe, GE, Tesla Powerwall, BYD, Fronius, Canadian Solar, Rinnai (where it is the #1 Australian retailer), Stiebel Eltron, Reclaim Energy, Viessmann, Haier, Apricus, and Emerald Energy — covering residential to commercial-scale systems (3kW to 60kW inverters). Its underlying technology capability is integration and installation rather than proprietary product development, anchored by in-house CEC-accredited design and installation teams, an in-house STC (Small-scale Technology Certificate) management service that monetises renewable energy certificates, and an Origin Loop Virtual Power Plant referral arrangement providing affiliate revenue.
Revenue is generated through three streams: one-time hardware sale and installation of solar, battery, heat pump, hot water, EV charging, and HVAC systems (the dominant stream); STC management professional services where the company acts as a registered trader with the Clean Energy Regulator; and Origin Loop VPP referral fees ($200 per customer sign-up plus $1/kWh during Loop events). Six Star Plus holds CEC solar retailer, designer, and installer accreditation, NETCC Approved Seller status, Solar Victoria Residential Electrification Grants Approved Provider status (enabling up to $2,800 per home in government rebates), GE Platinum Solar Retailer, REC Certified, and Tesla Accredited Installer designations, plus a carbon-neutral certified head office in Lynbrook, Victoria powered by 30kW of on-site solar.

Six Star Plus competitors and assessment
Company assessmentOthers
- Reclaim Energy: Australian manufacturer of CO2 heat pump hot water systems that is a Six Star Plus preferred installer partner. Reclaim is comparable as an adjacent electrification player but operates upstream in manufacturing rather than as a competing installer.
- GoodWe Australia: Australian arm of global solar inverter and battery manufacturer. GoodWe is a Six Star Plus technology partner but also enables competing installers; comparable as an ecosystem enabler rather than direct installer competitor.
Direct peers
- Solahart: Australia's largest residential solar hot water and solar PV installer with national dealer network. Solahart directly competes with Six Star Plus across rooftop solar, hot water, and heat pump installation for homeowners and builders across Australia.
- Natural Solar: Australian residential and commercial solar installer focused on premium solutions. Comparable to Six Star Plus in offering solar PV, batteries, and EV charging with builder channel partnerships and multi-brand product portfolio.
- RACV Solar: Royal Automobile Club of Victoria's residential solar and battery installation business. RACV Solar directly competes with Six Star Plus in the Melbourne/Victorian market with similar customer base of homeowners and brand-driven trust positioning.
Broad incumbents
- EnergyAustralia: Major Australian energy retailer that has expanded into solar PV and battery installation as part of a broader retail energy offering. Competes with Six Star Plus for solar installations but operates at national scale with a much wider product portfolio.
- Origin Energy: Major Australian energy retailer that already partners with Six Star Plus via the Loop VPP referral program. Origin also sells and installs solar/battery solutions directly, positioning it as both a partner and a broad incumbent competitor.
- AGL Energy: Australia's largest energy retailer with growing residential solar, battery, and EV charging installation business. AGL competes with Six Star Plus as a broad incumbent leveraging customer base and capital scale, but solar is one of many lines.
Emerging players
- Reposit Power: Australian VPP and battery aggregation platform that partners with installers. Reposit Power addresses the same customer base as Six Star Plus's Origin Loop referral relationship but focuses on the software/VPP layer rather than installation.
- Solar Choice: Australian solar comparison and installer marketplace. Solar Choice competes indirectly with Six Star Plus by routing leads to competing installers, but also represents a potential lead source/channel partner for the company.
