What Cool or Cosy does
Cool or Cosy (legal entity: Homeworks Co Pty Ltd, ABN 79 079 033 499) is a privately held South Australian energy solutions provider founded in 1984 and headquartered in Torrensville, SA. The company sells, supplies, and installs residential and commercial solar photovoltaic systems, home battery storage (Tesla Powerwall, sonnenBatterie, SolarEdge + LG Chem RESU), cellulose ceiling insulation under the in-house Supacell brand, and custom-manufactured roller shutters. Its product architecture is anchored by PERC mono-crystalline solar panels manufactured in-house at the company's Tindo Solar facility in Mawson Lakes, South Australia, following the ~2019–2020 acquisition of Tindo Solar — the company's most material strategic move and the basis of its Australian-made panel differentiation, supported by 295W/300W Tindo Karra panels with a 25-year product and performance warranty and third-party testing at the Desert Knowledge Australia Solar Centre in Alice Springs.
The business operates a direct-to-consumer, sales-led go-to-market with consultative in-home assessments, quote-based one-time pricing on solar/insulation/shutter lines, and a finance option ($0 deposit, up to 48 months interest-free) that introduces a recurring installment component. Customer segments are primarily South Australian residential homeowners, with a secondary commercial channel and minor community/school engagements; distribution is owned end-to-end via CEC-accredited in-house installation crews and field sales, plus a content/calculator-driven inbound funnel and a $250 cash referral program. Service quality and credibility are reinforced by Clean Energy Council Approved Retailer status (held since 2010), Australian Standards Licence 4859, and authorization as an SA Government Home Battery Scheme provider.
Revenue is generated principally through one-time sales and installation fees across solar PV, battery storage, cellulose insulation, and roller shutters, with monitoring sold as an add-on and finance offerings generating a recurring installment book. The company reports having served more than 45,000 customers and installed more than 14,000 solar systems (12,000 domestic and 300 commercial), and was named the largest South Australian Solar Retailer/Installer in both 2017 and 2018. The privately held Pty Ltd entity operates without disclosed external equity and is led by Managing Director Glenn Morelli, with expansion concentrated on in-state commercial solar, battery attach penetration, and Tindo Solar manufacturing scale-up aimed at both captive supply and export.
