Solar and a battery together pays for itself in about four years.

Fitted in one visit, both rebates already off the price. Add the three free hours of power every retailer now has to offer and it is quicker again. Owner-operated, licensed, and the bloke who quotes it is the bloke who installs it.

Why a battery, plainly

Four things it actually does

Cuts the bill

You stop buying back at night what you gave away at noon. Most homes we fit land between $1,200 and $2,000 a year.

Keeps the lights on

Whole-of-home blackout backup, not just a couple of powerpoints. Storms here take days to fix, not hours.

Rebate is at its peak

$251.60/kWh on the first 14 kWh until 31 December, then it steps down every six months until the program ends in 2030.

You choose when to buy

Charge off your own roof, ride out the evening peak, and stop caring what the retailer does with time-of-use pricing.

Get a fixed price

Solar and a battery fitted together is the fastest payback we quote; a retrofit onto panels you already own costs less up front but takes longer to come back. Interest-free finance via Humm, 12–72 months, up to $50,000, subject to approval. Weekly figures are indicative — your fixed quote is the number that counts.

Both ways in

Starting from scratch, or adding to what you have.

Doing the lot at once is the quickest payback we quote — one visit, one inverter, one application. Retrofitting onto panels you already own costs less up front but takes longer to come back. Both are fixed prices with the federal rebate already deducted.

Everything else we do

A real electrical contractor, not a sales company

Solar & battery

New systems, battery retrofits to existing solar, system upgrades, commissioning and fault-finding. SolaX is our standard fit; we also do Deye, GoodWe and Sigenergy.

Residential electrical

Rewires, switchboard and safety switch upgrades, lighting, powerpoints, ceiling fans, smart home and smart lighting retrofits.

Sheds & new builds

Shed wiring and sub-mains, new build rough-in and fit-off, granny flats, workshops and three-phase supply.

EV charging

Home and workplace charger supply and installation, load management so you're not tripping the main.

Commercial & industrial

Office fit-outs, LED upgrades, instrumentation, PLC and SCADA work, commercial solar with a proper ROI on paper first.

Faults and storm damage

Power out, board tripping, something burnt. You get the electrician who'll be doing the work, not a call centre.

How it runs

Four steps, no showroom

01
Ten minutes on the phone

We ask what you're paying, what you export and what you want backed up. If a battery won't pay for itself at your place, we'll tell you.
02
Four photos, one bill

Switchboard, meter, inverter and a roof shot from your phone, plus your last bill. Send it before lunch and you will have an indicative number that afternoon — next morning if it comes in late.
03
We come and look

Every house is different. We check the board, the roof and the cable run in person before we put a firm number on it — so the quote is the price.
04
Firm price, named week

Fixed quote in writing with the rebate already off. Accept it and we book you into a named install week and order your gear.

Where we work

We live here. That's the difference.

BD NRG is based in Valdora, in the Maroochy River valley. When something needs looking at, you get the bloke who installed it — not a call centre in another state and a subcontractor three weeks out.

Straight answers

The questions we get asked

Do I have to pay the rebate up front and claim it back?

No. We claim the federal rebate on your behalf and it comes off the quoted price before you pay anything. The number you see is the number you pay.

Can I add a battery to solar someone else installed?

Almost always. A retrofit sits alongside your existing system and costs less up front than starting over. It does take longer to pay for itself than fitting the panels and battery together — around seven to nine years against about four — so we show you both numbers and let you pick. We'll check your inverter and switchboard from photos before we price it.

What happens after 31 December 2026?

The rebate drops from $251.60 to roughly $211 per kWh, then steps down again each 1 January and 1 July until the program ends in 2030. On a 19.2 kWh system that first step is about $704 out of your pocket.

Is there a Queensland rebate as well?

Not currently. The state Battery Booster program closed in 2024, so the federal scheme is the only rebate running.

Who actually turns up on the day?

Bart, plus an offsider. Owner-operated, 20-plus years on the tools, QLD Electrical Contractor Licence 1508403, and accredited for both design and installation of solar and battery storage — SAA S8787501.
