brought home to your south australian roof
20 years inside the energy industry,
brought home to your roof.
Twilight Energy was founded by people who've worked at the energy companies, the solar retailers, and the network operators. We know which brands actually last. We know which retailer plans actually pay. And we install with the care of people who'll still be answering the phone in ten years.

why twilight
Three things we do differently.
The South Australian solar market is full of cheap quotes and broken promises. We exist for everyone who's been burnt by that, or who doesn't want to find out the hard way.
Brands we know and trust, no compromises
Tier 1 panels (Jinko), premium inverters (Sigenergy, Tesla, GoodWe), and best-in-class batteries (Tesla, Sigenergy, GoodWe). We don't stock budget brands. Period.
We deliver on what we promise
Quotes that match the invoice. Install dates we keep. A team you can call afterwards. Boring? Maybe. And it's why our customers refer their neighbours.
ROI that lasts past install day
The right energy plan paired with your system can almost double your savings. We review your retailer plan every year and tell you when to switch. Most installers won't.
what we do
More than solar. The full home energy stack.
We're agnostic about technology: meaning we recommend the best mix of solar, battery, EV charging, and heat pumps for your home, not the one we make the most margin on.
Solar panels & inverters
Tier 1 panels and inverters, 25-year warranties
Panels and inverters from manufacturers with proven Australian service networks, so when something goes wrong in 2046, the phone still picks up.
battery storage
Sized to your usage, not ours
We analyse your current consumption using advanced modelling software and size your battery to match your needs. We will discuss electrification opportunities and will present the best value option for your situation.
EV charging & V2G
Charge from your roof. Future-proof for V2G.
AC chargers can be paired with your solar so you fuel your car from the sun. Many of the Twilight team have EV's at home so are well placed to advise you from first-hand experience. More on V2G readiness ↓
Heat pumps
Hot water and air conditioning, electrified
The single biggest gas-to-electric switch you can make. Pair with solar, a few smart programming options, and your hot water bill effectively goes to zero and you can significantly reduce your air con costs.
Proudly Aboriginal owned and operated.
About Twilight Energy
Twenty years inside the energy industry.
Every install done in-house.
Twilight Energy was started by people who'd spent two decades inside the energy industry: at the retailers, the solar companies, and the electricity distribution networks. We've seen which brands fail in the Australian sun, which inverters survive SA's grid, and which retailer plans quietly chip away at your savings. We bring that experience to every quote.
What truly sets us apart is who actually shows up at your roof. Twilight installations are performed by our own SAA-accredited installers, full-time members of the Twilight team. The crew that quotes the job is the crew that installs it, commissions it, and answers the phone if anything ever needs attention.
You'll most often deal with Cam or Ben, who look after design and customer assessments, and Tom, our head electrician, both familiar faces on Adelaide rooftops and across our Google reviews.

01
Free home assessment
On-site or remote. We look at your roof, shading, switchboard, and your last 12 months of energy bills. No deposit, no obligation. If your roof isn't suitable, we'll tell you.
02
Designed for your home
System sized to your usage -not the biggest one we can sell you. We model generation against consumption- taking future needs into account- before recommending kW and battery size.
03
Quoted with everything included
STC rebate, federal Cheaper Home Batteries Program, and any current SA scheme, all factored in upfront. The price you see is the price you pay.
04
Installed by accredited tradies
Our crew, not subcontractors we've never met. Clean Energy Council accredited, fully licensed electricians. We're on every roof from start to finish.
05
Optimised energy plan: and yearly reviews
We model your new generation profile against current SA retailer offers and recommend the best plan. Every 12 months we check again. This is the part most installers skip.
Point Pearce solar & battery Project
47 homes.
One community.
Powered after dark.
At Point Pearce, on South Australia's Yorke Peninsula, we're fitting rooftop solar and battery storage to 47 homes, delivered with the Point Pearce Aboriginal Corporation and AGL. Households generate and store their own energy, taking control of their power and easing cost-of-living pressure.

EV charging & V2G readiness
Set up your home today for the cars of
the next decade.
Australia's EV fleet is doubling every two years and bidirectional charging is rolling out fast. The smart way to install solar and battery now is with the inverter and switchgear that lets your car connect to your home, without rewiring later.
V2L
Your car as a power outlet
Plug tools and appliances directly into the EV. Most modern EVs already do this: useful for camping, jobsites, and short blackouts. No extra hardware needed beyond the cable that comes with the car.
Available today on most EVs
V2H
Your car as a home battery
Bidirectional charging powers the whole house from your EV during outages or expensive grid hours. Available now in Australia via the Sigenergy bidirectional DC charger, paired with the same Sigenergy battery system we install.
Live in Australia · CEC approved
V2G
Sell back to the grid
Trade stored energy from your car battery to the grid when wholesale prices spike. The first AS/NZS 4777.2-compliant V2G hardware is already CEC-approved; manufacturer activations and EV firmware updates roll out across 2026 and 2027.
Hardware ready · Activations rolling out
Sigenergy is part of our standard range
So the bidirectional charger that already exists in Australia plugs straight into the system we recommend, not a bolt-on retrofit.
Every install is V2G-ready
We size your inverter and switchboard for bidirectional load, so the future upgrade is a connection, not a renovation.
We model the EV-charging value first
Driving patterns, solar generation, retailer plan, we run the numbers before you buy, so you don't pay for capacity that won't earn its keep.
Heritage & character homes
Solar that respects the street it sits on.
Including Colonel Light Gardens.
Heritage-listed suburbs like Colonel Light Gardens have specific rules, and even where they don't, character homes deserve an install that doesn't shout. We've done dozens, and we treat each roof like it's still going to look right in 50 years.
Discreet, all-black panels
Aligned to ridge lines and out of sight from the street wherever the roof allows.
Heritage council literacy
We know which Adelaide council overlays apply, and we handle the approval paperwork before a single panel goes up.
Care on fragile roofs
Tile, terracotta and original corrugated iron get a different rail system, different fixings, and a different crew briefing.
Cabling kept discrete
Internal runs wherever feasible, soffit penetrations, and battery siting planned so the original facade stays untouched.
Specialist installs across Colonel Light Gardens, Unley, Norwood & the inner south.

The Twilight difference
Your solar system is half the savings.
Your retailer plan is the other half.
Most installers walk away the day the system is commissioned. That's when a quiet, expensive thing starts happening: you're now exporting to a retailer plan that wasn't designed for solar households.
Because we came from inside the energy industry, we know the maths behind every retailer's offer. We model your generation and consumption against current SA plans (AGL, Origin, Amber, Flowpower, Globird, and others) and tell you which one returns the most given how you actually use power. We re-check every 12 months.
It's a free service for our customers. It's also, quietly, one of the single biggest reasons our return-on-investment numbers beat the competition's.

"Extremely pleased with the solar system installed by Twilight Energy. Quote and installation was very smooth and professional. After the install, they spent time and stepped me through how to use the app and monitor energy production."
