Found on Google. Back for a battery. Priced on the roof.

“Near me” and Penrith top what people type.4 No directory of installers or sellers here can be browsed or counted.5

Nearly two in five houses here already carry a system,11 and the growth is a battery onto one that already has panels, 2.01 to one.6 A sale that started with a knock gives ten business days to walk, and the agreement’s front page has to say so.9,10

The retailer has ten paragraphs to put in writing before a certificate can exist, and the statement is theirs to sign.8 A battery certified after New Year earns fewer certificates than one certified before it.7

Your design software may already draft the proposal and take the signature: OpenSolar says so on its own feature pages, read 22 September 2026.

1. Published. Telsyte Australian Artificial Intelligence Study 2026, read 25 August 2026. Online survey, April to May 2026, 2,023 Australians aged 16 and over, for the 12% now naming an AI tool as their main way of finding information online (5% a year earlier) and for the half who would rely on the summary and never click through.
2. Verified. Google’s AI features documentation, 10 December 2025: “There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary.” Google, Tips to improve your local ranking on Google, support.google.com, read 29 August 2026, for “There’s no way to request or pay for a better local ranking on Google.” The four things that get a page quoted are a controlled study of 252,000 trials, arXiv:2605.25517; our Get Found page carries it in full.
3. Verified and measured. ABS, “Alphabetic index of primary activities”, ANZSIC 2006 Revision 2.0, read 6 September 2026: a case-insensitive search of the whole index for “solar” or “photovoltaic” returns four entries and not one of them is rooftop solar installation; a solar hot water system sends you to Plumbing Services, class 3231. A second search for “batter”, “electric vehicle” or “charging” returns nine entries, all manufacturing, wholesaling or retailing of the physical battery, and home battery installation appears nowhere in the index.
4. Measured, and localised to one machine. Google’s public autocomplete endpoint, queried with the Australian parameter on 6 September 2026, fifteen prefixes, raw responses saved. Under “solar installer”, 9 of the 10 suggestions are the trade plus a place, “solar installers near me” first and “solar installers penrith” second. These results are localised to the machine they were run on, which is in the Blue Mountains, so they are evidence of how local this category is rather than of national demand.
5. Verified. All read 6 September 2026. Solar Accreditation Australia’s own tool is headed “Check Installer Accreditation Status” and takes an accreditation number or a person’s first and last name, so it answers a question about somebody you already know and cannot be browsed, filtered or counted. The New Energy Tech Consumer Code’s find-an-approved-seller page returns HTTP 200 and renders no seller list at all in the served HTML, and every link on it and on the program page was enumerated with no register among them.
6. Measured. Clean Energy Regulator, small-scale installation postcode data, current as at 31 July 2026, re-measured on 8 September 2026 across the thirteen councils of this catchment: 60,753 battery installations against 30,151 new solar installations over the thirteen months to July 2026, 60753 / 30151 = 2.01 to one, against 1.43 to one nationally over the identical thirteen columns.
7. Verified. Renewable Energy (Electricity) Regulations 2001 (Cth), Compilation No. 90, compilation date 1 May 2026, authorised version F2026C00383, read 6 September 2026. The factor table at reg 20(8): a battery certified between 1 May and 31 December 2026 earns 6.8 certificates for each of its first 14 usable kilowatt-hours, and 5.7 from 1 January 2027, a drop of 16.2% (5.7 / 6.8 = 0.8382). reg 19D(4)(c): the date that decides the count is the day the battery is certified, not the day it is installed.
8. Verified. Same Regulations, reg 20AC(5A), read 6 September 2026: ten paragraphs the solar retailer must have stated in writing before anybody may create a certificate, including whether the installer is an employee or a subcontractor, the feed in tariffs and export limits, and the expected payback period, energy savings or cost savings. reg 20AC(7) requires every statement to say the information is true, correct and complete.
9. Verified. Australian Consumer Law, Schedule 2 to the Competition and Consumer Act 2010 (Cth), Compilation No. 165, compilation date 1 July 2026, read 6 September 2026. s 79 requires the agreement’s front page to carry a notice that “conspicuously and prominently informs the consumer of the consumer’s right to terminate the agreement”, and s 80 requires the salesperson to set out their own name and business address.
10. Verified. Same Australian Consumer Law compilation, read 6 September 2026: s 82 gives the customer to the end of the tenth business day to terminate an unsolicited agreement, and the maximum penalty under s 224(3) item 5 is up to AU$50,000 for a company and up to AU$10,000 otherwise, for each act or omission.
11. Verified and measured. Australian PV Institute Solar Map, supported by the Australian Renewable Energy Agency, accessed from pv-map.apvi.org.au on 6 September 2026 with its downloadable local government area dataset. Re-measured on 8 September 2026 across the thirteen councils of this catchment: 310225 / 812769 = 38.2% of suitable houses already carry a system, against 39.1% across New South Wales.
12. Verified. Clean Energy Regulator, registered agents page, the page’s own stamp “Last updated 31 July 2026”, read 6 September 2026: “We offer a financial incentive to install small-scale renewable energy systems. It’s not a rebate. We don’t pay money to system owners or registered agents.” A system owner instead assigns the right to create certificates to an agent for an upfront discount on the purchase price.
