Global Sustainable Energy Solutions

What Global Sustainable Energy Solutions does

Global Sustainable Energy Solutions (GSES) is an Australian private company founded in 1998 that operates as a Nationally Recognised Registered Training Organisation (RTO Code 91461) delivering accredited solar photovoltaic, battery storage, and stand-alone power system training. It monetises through per-course fees ($30–$4,895) for accreditation pathways recognised by Solar Accreditation Australia, CPD and Sprint short courses for ongoing professional development, and an industry-leading textbook and e-book catalogue (over 30,000 publications sold). The company serves primarily licensed electricians, engineers, and solar installers seeking SAA accreditation, with delivery via self-paced online learning combined with face-to-face practicals at the NECA Training Centre in Chullora, Sydney.

Beyond training, GSES runs a parallel consulting and inspection business for solar assets. Services include owner's engineer advisory for renewable energy projects (30kW to 5MW), commercial and residential solar inspections, warrantied inspections, and mandated Clean Energy Regulator compliance inspections across Australia. Named clients include Coles, Woolworths, the University of Sydney, NSW Department of Education, UNIDO, and the governments of Papua New Guinea, Tuvalu, and Vanuatu, with work executed across 41 countries.

The company has two technology-oriented sub-brands: DIAGNO, an AI-enabled asset management platform providing real-time performance monitoring and predictive analytics for solar portfolios, and Mindaro, a 2024-built standalone subsidiary (formerly the GSES Design Team) delivering on-demand design and engineering services for commercial and industrial solar, battery, and EV charger projects. Distribution combines direct e-commerce, referral partnerships with SolarQuotes, OpenSolar, BayWa r.e., and One Stop Warehouse, and direct enterprise sales for consulting engagements. Revenue is not publicly disclosed.

Recent moves7 records

Expansion highlights5 records

Direct peers

• NABCEP: North American Board of Certified Energy Practitioners — the dominant US solar PV installer and designer certification body. Operates the same SAA-equivalent accreditation scheme in North America with associated training provider accreditation, making it the closest international analogue to GSES's SAA-aligned RTO model.
• Solar Energy International (SEI): Colorado-based non-profit founded in 1991 that delivers solar PV, battery storage, and microgrid training plus workforce credentialing. Closely mirrors GSES's curriculum (design, install, battery), training modality (online + in-person), and textbook publishing model.
• Everblue: Online training provider for NABCEP PV and energy auditor certifications, with self-paced coursework and live instructor support. Directly competes with GSES in the electrician/engineer accreditation pathway via digital delivery.
• SkillFront: Online continuing-education platform offering solar PV installer courses with globally recognised certificates. Targets the same electrician/renewable energy professional cohort as GSES via digital-only delivery, often at lower price points.

Broad incumbents

• Clean Energy Council (CEC): Australian industry peak body that previously ran the accreditation scheme (handed to SAA in 2024) and still administers solar retailer approval and consumer advocacy. Provides overlapping education content and standard-setting influence, making it the natural Australian incumbent counterpart.
• TAFE NSW: Australia's largest vocational training provider, delivering similar electrical and renewable energy certificates through government-funded RTO status. Overshadows GSES in scale and breadth but addresses overlapping electrician upskilling needs in NSW.

Regional players

• Solar Energy UK: UK industry association running its own accredited solar installer scheme (MCS) and training pathways. Operates an analogous accreditation-and-training ecosystem to GSES's SAA-aligned offering, but geographically bound to the UK.
• SolarPower Europe: European solar industry association that coordinates workforce certification and standards across the EU. Plays a comparable standard-setter and training influencer role to GSES at a regional level.

Emerging players

• OpenSolar: Free solar design and sales SaaS platform used by installers in 150+ countries. Has a formal partnership with GSES for knowledge sharing and increasingly bundles educational content into its installer onboarding.

Others

• HeatSmart (UK): UK-based renewables training provider focused on heat pumps and complementary low-carbon technologies. Targets a non-overlapping technology vertical but competes for the same electrician continuing-education wallet share.
