The licence side is shared with all electrical work in South Australia. The business contracting for the install needs a CBS electrical contractor licence and has to show its licence number in public advertising, a website included, and the work is certified with an electronic certificate of compliance. Our Adelaide electricians page goes through those rules, and our solar installers page covers SAA accreditation, Approved Seller status and the federal battery discount.
What's different here is how far the state has gone. In September 2025 the head of SA Power Networks said half of South Australian households had rooftop solar, with about 100 home batteries a day going in under the federal rebate. On mild, sunny days with little demand, the network can have more solar than it can safely carry. SA Power Networks says that if the market operator directs it, it would switch off large solar and wind farms first, then large commercial systems, then household exports through the Relevant Agent and dynamic export functions, and only after that any remaining rooftop systems. It describes this as rare and a last resort. Because buyers read about it in the news, a battery page that explains it calmly, and says what happens to their own use of power, earns trust.
Every metropolitan roof, from Gawler and Playford in the north to Onkaparinga in the south and the Adelaide Hills to the east, sits on the one distribution network. That keeps a site simple: one set of connection rules and one Portal to explain, instead of the network-by-network pages a Melbourne or Sydney installer needs. The variation is in the export limit each address gets. SA Power Networks' Service Performance Checker shows past flexible limits at an address, and it warns that these aren't a reliable guide to the future. Point buyers to it with that caveat, rather than printing a typical export figure.
Further out the rules change. Rural customers on single wire earth return (SWER) lines can now have up to 10 kW of solar and 10 kW of battery each, up from the 5 kW they were historically held to, under SA Power Networks' Flexible Exports offer. Some SWER areas are still limited, and some customers can't export at all. If you work in the Barossa, the Fleurieu or the Murraylands, a short page for SWER properties tells farmers and lifestyle-block owners you know the difference.
WebCraft Studio is an Adelaide team at Ste 3/110 Hutt St. We haven't built a site for a solar company yet, so the examples below are South Australian businesses whose sites have the same moving parts. Projects run by phone and email, which suits installers who spend the day on roofs, and if you'd rather meet first in Adelaide, that can be arranged.
