Energy Saving Smart Homes

Put your own solar to work at home, heating your hot water instead of exporting it cheaply to the grid.

What we offer

Use more of your own solar with eddi

Most solar systems send any power you don’t use straight back to the grid, usually for a small feed-in credit. The myenergi eddi is a solar power diverter that keeps that surplus at home. It monitors what your home is exporting and sends the excess to your hot water system or electric heating instead, so you’re heating with your own solar rather than paying for it later.

You stay in control through the myenergi app: see your import and export at a glance, use boost when you need hot water in a hurry, and set timers to make the most of cheaper off-peak rates. eddi also pairs with other myenergi devices, such as the zappi EV charger, so your solar goes where it’s most useful.

We supply, install and set up eddi like any other electrical job: we check your hot water system and switchboard are suitable, fit the grid sensor, set eddi up to work with your existing solar, and walk you through the app before we leave.

See what solar can power in your home

Switch on the upgrades that suit your home and adjust the figures to match your bills. The estimate updates as you go and shows where running everyday loads on your own solar makes the biggest difference.

Your rates and solar Defaults are typical NSW averages for 2026–27. Swap in the numbers from your own bill for a closer estimate.

Typical NSW average single-rate usage charge, including GST (about 32–34c across Ausgrid, Endeavour and Essential).

Typical NSW average controlled load rate, including GST (about 19–22c).

What your retailer pays for exported solar. IPART’s 2026–27 NSW benchmark is 3.4–6.5c.

Typical NSW average gas usage rate (Jemena network), including GST.

Enter 0 if you don’t have solar yet.

Yearly average. Around 4–5 hours is typical for Sydney.

Fridge, standby and other loads already using solar.

Upgrades to include

Includes the transformer. Most MR16 halogens draw about 50–60 W.

eddi needs an electric tank, so it’s only available if you have one.

Lower in winter; 70–85% is typical over a year.

Higher if the car is home during the day.

A typical open-plan living area needs about 4–6 kW.

Pre-heating in the afternoon on solar before the sun goes down.

Typical electric rails are 60–150 W.

24 if they’re left on all the time.

Typical ceiling exhaust fans are 15–50 W.

Fans wired to the light often run whenever the room is in use.

Rebates and incentives One-off discounts from current NSW and Australian Government programs, shown separately from the yearly savings. Each counts only when its upgrade is switched on. Amounts depend on eligibility, the product and the provider, so replace them with the figure on your quote.

NSW Energy Savings Scheme: up to $640 replacing an electric water heater with a heat pump, or up to $330 replacing gas. Heat pumps can also earn federal STCs, which vary by model.

NSW Energy Savings Scheme: up to $550 for a new 6 kW reverse-cycle system, or up to $560 replacing an old air conditioner.

Australian Government Cheaper Home Batteries Program, worked out from the battery size you entered. Joining a virtual power plant can add a NSW incentive on top.

How we estimate

Every figure is an editable starting point based on typical NSW averages, not a Speedy Sparky quote. Solar you use at home is costed at the feed-in tariff, because that’s the credit you give up by not exporting it.

  • Rates: 33c/kWh general usage is the average single-rate charge across NSW’s three networks (Canstar, September 2026: Ausgrid 32.3c, Endeavour 32.7c, Essential 34.4c). 20c/kWh controlled load reflects average NSW controlled load rates (Canstar, January 2026: about 19–22c). 5c/kWh feed-in sits within IPART’s 2026–27 all-day benchmark of 3.4–6.5c. Gas at 4.5c/MJ and 78c a day is the average on the Jemena network (Finder, October 2026). All include GST.
  • Solar output: system size × usable sun hours × 80% (allowing for heat, shading and inverter losses). If the upgrades you pick want more daytime solar than is left after your existing daytime use, the solar share of each upgrade is scaled back to fit and the rest is costed at the grid rate.
  • Lighting: halogen downlight about 50 W including its transformer; LED replacement about 6 W; used at night, so costed at the grid rate.
  • Hot water: about 2.6 kWh of heat per person per day plus 1.5 kWh a day of tank losses. Electric tank 95% efficient; gas 70%; heat pump about 3.5 units of heat per unit of electricity. The part not heated by solar is costed at your off-peak rate if you’re on controlled load, otherwise the general rate.
  • EV vs petrol: EV about 16 kWh per 100 km including charging losses; a comparable petrol car about 8 L per 100 km at $2.00 a litre (typical Sydney unleaded). Both are costed for the same kilometres. The EV row always shows the petrol comparison; choose “Running a petrol car” to count it in your total.
  • Daytime appliances: dishwasher about 1.2 kWh a load, warm-wash washing machine about 0.8 kWh, vented or condenser dryer about 2.8 kWh.
  • Heating: gas space heater about 80% efficient; reverse-cycle air con about 3.8 units of heat per unit of electricity.
  • Pool pump: runs the same hours either way; the saving comes from running on solar instead of the grid.
  • Cooking: gas cooktop about 40% efficient; induction about 85%.
  • Battery: 90% round-trip efficiency; daily use limited to the smaller of the battery size and your evening use.
  • Heated bathroom floors: mat output × floor area × hours on. A smart timer trims the running time you enter, and the share run in the solar window (when tiles can store the warmth) is costed at the feed-in tariff.
  • Heated towel rails: rail wattage × hours on per day, before and after a timer. Timer hours in the solar window are costed at the feed-in tariff.
  • Exhaust fans: fan wattage × hours running, before and after a run-on timer or humidity sensor. The power saving is small; the bigger benefits are less mould and less heated or cooled air pushed outside, which isn’t counted here.
  • Fans and timers: each ceiling fan about 35 W, replacing the air con running time you enter.
  • Emissions: about 0.64 kg CO₂-e per kWh from the NSW grid, 0.0514 kg per MJ of natural gas and 2.3 kg per litre of petrol.

Rebates and incentives are one-off amounts, so they’re shown separately from the yearly savings and added only to the first-year benefit. They’re upfront discounts arranged through accredited providers, eligibility applies, and program amounts change over time.

  • Hot water: NSW Energy Savings Scheme discount of up to $640 replacing an electric water heater with a heat pump, or up to $330 replacing gas (NSW Climate and Energy Action). Federal small-scale technology certificates (STCs) for heat pumps vary by model and aren’t added here.
  • Air con: NSW Energy Savings Scheme discount of up to $550 for a new 6 kW reverse-cycle system, or up to $560 replacing an old air conditioner.
  • Battery: Cheaper Home Batteries Program. For installs from May to December 2026, each usable kWh earns 6.8 STCs for the first 14 kWh, 60% of that from 14 to 28 kWh and 15% from 28 to 50 kWh. STCs are valued at about $38 each (the market price was just under $40 in October 2026). The STC factor steps down every six months from 2027, so the discount shrinks over time. The NSW virtual power plant incentive varies by provider and isn’t added here.
  • Lighting, EV charging and other upgrades: no current NSW or federal household rebate is included.
