What matters to you
"Bills keep going up even with solar — we feed power in for almost nothing then buy it back at night."
03 Who you are dealing with
We don't sell a battery.
We engineer a good system.
10 years — and still here
Your battery warranty lasts 10 years. Esena has been here for 10. We'll still be here to support it — which is more than most solar companies can say.

The system we've designed for your home
10.23 kW Trina solar + 13.5 kWh battery
- Purpose-built for your roof and usage — not an off-the-shelf package.
- Sized to the federal rebate sweet spot (full rate on the first 14 kWh).
- Backup power through outages and VPP-ready — you take control of your bill.
02 Why your bill keeps climbing
The grid only gets
more expensive.
Network rates up ~70% since 2015. Feed-in tariffs collapsed to near zero — export charges may follow.
Today · renting from the grid
Right now, you're fully exposed to the grid.
- Every kWh you use comes from the grid at around 37c — and it only climbs.
- Network rates are up ~70% since 2015, with no ceiling in sight.
- Feed-in tariffs have collapsed to ~2c, so exporting power barely pays.
- When the grid goes down, so does your home.
vs
With Esena
Own your power — don't rent it.
- Cover far more of your usage from your own system, not the grid.
- Use your power when it's worth the most — day and night.
- Lock in against rates that only ever rise.
- Take back control of a bill you currently can't touch.

04 How we get you installed
A managed path — nothing left to chance.
Step 1
Discovery call
We understand your setup, bill, and goals — so we recommend the right system, not just any system.
Step 2
Qualifying
We confirm you're in our service area and that solar or battery is the right fit for your home.
Step 3
Design & tailoring
We size the system to your actual roof, usage, and goals — not a one-size guess.
Step 4
SEG & approvals
We handle all grid applications, rebates, and council paperwork on your behalf.
Step 5
Install booked
Your date is locked. We coordinate stock and our accredited installation team.
Step 6
Install day
Accredited Esena installers on site. Start to finish in typically one day.
Step 7
Follow-up (1 week)
We guide you through the app, help with retailer setup, and confirm your savings are live.
Step 8
Ongoing support
Wi-Fi monitoring, software updates, one call away. We’re still here 10 years later.
All we need from you today: a clear photo of your switchboard/meter and a recent power bill — most of which we already have on file.
05 How the savings actually happen
Use your own power at the
right time of day.
Your power, measured across the day ↓
6am – 11am
Panels wake up — charge the battery first.Overnight off-peak — the battery charges at the cheapest rate of the day.
11am – 2pm
Peak sun. Run the dishwasher, pool pump & washing on free power.Daytime off-peak — top up the battery while grid rates are low.
2pm – 6pm
Battery tops up to full instead of exporting for cents.Battery holds its charge, ready for the expensive evening.
6pm – 11pm
Evening peak — run the house on stored power, not 37c grid.
1
Self-consumption. Every kWh you use from the battery is a kWh you don't buy at 37c.
2
Arbitrage. Store energy when it's cheap or free, spend it when it's expensive.
3
Backup & VPP. Keep the lights on in an outage — and earn from a Virtual Power Plant if you choose.
