This week SolarQuotes ticked over one million quote requests. Somewhere in a database is customer number one1, and somewhere in the queue right now is customer number one million.
I thought it’d be a good excuse to look back. Some things about solar in Australia have changed almost beyond recognition. Other things haven’t budged an inch. Here’s five of each.
SolarQuotes started in my walk-in wardrobe, in a rental in Adelaide. These days we’ve got an actual office in the Adelaide CBD.
Back in 2009 the global average price for a solar module was around US$2.18 a watt. By late 2025, module prices had crashed to under US$0.10 a watt in some markets. That’s A 95% fall.
There was barely a home battery market in 2009. Tesla’s Powerwall didn’t exist until 2015, so anyone storing solar back then was doing it with lead-acid batteries. BloombergNEF’s data shows lithium-ion battery packs averaged well over $1,200/kWh in 2010. Their most recent survey has that down to $108/kWh globally, and stationary storage specifically down to just $70/kWh.
In 2009, renewables made up about 5% of Australia’s electricity generation. The National Electricity Market just hit a new quarterly record of 42.1% renewables in Q2 2026. Coal’s gone from supplying the vast majority of the grid to under half.
When I started this site, there were just over 14,000 solar PV systems connected to the grid across the whole country. By the end of November 2025, that number had passed 4.62 million. There are now more rooftop solar systems in Australia than there are Australians in most cities.
I dug out a photo of an Australian solar wholesaler’s brand board from 2009. Of the panel manufacturers on it, none are still selling in Australia the way they were then. BP Solar, Sharp, Sanyo, Evergreen, Schott, Kyocera, Mitsubishi, GE, Conergy, all gone. Suntech and SunPower both went bankrupt and got picked up by new owners, so what’s selling under those names today isn’t really the same company. Yingli Solar was delisted from the NYSE in 2018, and came within a whisker of full liquidation in 2020. Trina Solar is the one panel brand from that era I could confirm was already supplying Australia in 2009 and is still trading here largely unchanged – we still recommend it.
2. One Grid Connect Solar Inverter Brand
On the inverter board Fronius is the only brand I can think of still going strong for on-grid in Australia. Selectronic, Victron Energy and Outback Power Systems are all still around for off-grid. SMA’s still here but pulled out of residential.
Am I missing anyone? Genuinely curious if there’s a brand from the early days still trading here that I’ve overlooked.
Adelaide Solar Systems (under new owners now) and Solar Wholesalers (still with the same owners) are both still going, and still among the installers I’d point an Adelaide homeowner toward today. Without Paul from Adelaide Solar and Andy from Solar Wholesalers agreeing to be guinea pigs for a bloke running a comparison site out of his wardrobe, there’d be no SolarQuotes.
In 2009 it was me, Chantel and John doing IT. John is still running the show IT-wise. In seventeen years, not one person we’ve hired as a full-time employee has decided to leave the business, aside from Rino, who retired this year after a long run. We’ve built this place on truth-telling, strict vetting of installers, and free personal support for anyone electrifying their home, and the fact that the same people are still here, upholding that seventeen years on, says something about how seriously we take it.
All of the above is nothing without the people who climb on your roof. Installing solar is a genuinely tough job. You’re up on a hot tin roof in a heatwave, and/or hauling 150kg batteries into place, opening up switchboards that might have asbestos, or snakes in them, working around voltages that don’t forgive mistakes. And they’re doing it while competing against mobs who don’t understand, or don’t care about, the idea of a sustainable margin.
They stick at it anyway. Because at the end of the day, it’s their work that gets you a system that actually holds up, keeps your bills down, and might just keep the lights on when the grid doesn’t. All SolarQuotes really does is shine a light on the good ones.
A million people registering with a website is a nice stat, but the real wonder is the hundreds of thousands of installs, done by the sparkies, apprentices and small business owners who built this revolution with their own hands.

I’m a Chartered Electrical Engineer, Solar and Energy Efficiency nut, dad, and the founder of SolarQuotes.com.au. I started SolarQuotes in 2009 and the SolarQuotes blog in 2013 with the belief that it’s more important to be truthful and objective than popular. My last “real job” was working for the CSIRO in their renewable energy division. Since 2009, I’ve helped over 800,000 Aussies get quotes for solar from installers I trust. Read my full bio.
👏Congratulations to the team at Solarquotes
Congratulations on your first million to Finn for giving birth and everyone at Solar Quotes for parenting and making it what it is today. And that stat of no-one leaving (apart from Rino who gets a free pass) is remarkable. Not only in SQ the best solar comparison and assistance site by far it is the Hotel California of employers!
I have benefited greatly from all of the support and information here on SQ, not just from those employed at SQ but also from the many SQ subscribers and installers who provide their opinions and information in their blog comments. Although some occasionally speak a language in don’t understand! 🙂
They say “How do you become a multi-millionaire? – Be a millionaire already!”. Well, now you have done it, what next? World domination? An office in Monaco? Or just keeping on doing what you do best.
Congratulations to all of you. And thanks.
Well done to you Finn, and all the staff that have put in during the past 17 years or so.
The site is such a valuable tool for those entering the extremely confusing web of solar, battery, and retail power, plans etc.
Even though I didn’t go with one of the 3 SQs I received back in late 2023, the blogs, the 101’s, the YouTube videos, comparison charts, etc are all invaluable to get a little self education so you can ask the right questions of the solar sales people.
All the best into the future.
Please keep the SolarQuotes blog constructive and useful with these 5 rules:
1. Real names are preferred – you should be happy to put your name to your comments.
2. Put down your weapons.
3. Assume positive intention.
4. If you are in the solar industry – try to get to the truth, not the sale.
5. Please stay on topic.
