Western Sydney runs hotter, harder and longer on ducted A/C than any other part of the city. We size your solar and battery from your actual Ausgrid NMI data — not postcode averages — so your system matches your real summer loads, not someone else's.
Western Sydney's extreme heat, large households and A/C-heavy lifestyles create energy profiles that generic installers routinely misprice. We do the analysis properly.
Ducted air conditioning is the dominant load in Western Sydney homes — often drawing 4–8 kW continuously on 40°C days. We identify your peak summer consumption windows from your NMI interval data and size your system to capture those peaks directly, so solar powers your A/C instead of exporting at a low feed-in rate while you pay peak tariffs.
Many Western Sydney households have 4–6+ occupants with correspondingly high baseline consumption — multiple fridges, extended cooking hours, large hot water systems. We size from your actual 12-month NMI data rather than a generic "3-person household" template, so your system genuinely covers your family's needs.
The most effective battery strategy in Western Sydney isn't just peak arbitrage — it's pre-cooling. We model how using solar to aggressively cool your home between 10 am and 3 pm, before Ausgrid's 4–9 pm peak window, reduces the thermal load your battery needs to cover in the evening. This combination consistently outperforms simple arbitrage calculations.
Western Sydney households often consume 30–50% more electricity than Sydney-wide averages suggest. If we size your system to an average, you get an undersized system that falls short in summer. We request your actual half-hourly Ausgrid interval data via your NMI number and build the entire system design around your household's real usage pattern.
New estates in areas like Merrylands, Guildford and Granville frequently come with builder-included 6.6 kW systems that are routinely undersized for Western Sydney A/C loads. We audit existing systems against your NMI data and identify whether adding panels, upgrading the inverter or adding a battery delivers the best return on your energy dollar.
We are not aligned to any single panel, inverter or battery brand. Our recommendations are based on performance data and your verified consumption profile. If a system won't achieve a reasonable payback for your household, we'll say so — not sell you one anyway.
Share your NMI number and we pull your actual Ausgrid half-hourly interval data. We review 12+ months of consumption to identify your seasonal peaks, daily load curves and A/C contribution before making any recommendation.
We model your roof's solar generation hour by hour and overlay it against your actual summer consumption profile — identifying exactly how much of your peak A/C load solar can directly power, and what remains to be covered by battery or grid.
We design a system around your verified loads, recommend a battery size based on real peak-period displacement (not rule-of-thumb), and where relevant, outline a pre-cooling schedule to maximise summer savings before the peak window opens.
Our accredited installers handle all aspects of the installation including switchboard assessment, metering upgrade if required, and grid connection paperwork with Ausgrid.
We verify first-summer performance against our model and follow up if output or savings fall short of projection. Western Sydney's summer is the make-or-break season for solar ROI — we make sure yours delivers.
Premium Tier 1 panels sized to your actual household loads. Larger systems (10–13 kW) recommended for high A/C and large family homes. Full CEC accreditation.

Smart scheduling of pool pumps and A/C pre-cooling to solar generation windows — turning your biggest loads into solar-powered assets instead of bill drivers.
Existing system underperforming? We benchmark your current output against your NMI data and recommend targeted upgrades — additional panels, inverter replacement or battery addition.
It helps more than it hurts. While very high temperatures (above ~25°C) do slightly reduce panel efficiency (roughly 0.3–0.5% per degree above 25°C), this is more than offset by Western Sydney's long daylight hours and strong summer irradiance. More importantly, solar generation peaks at exactly the same time as your ducted A/C is working hardest — meaning your system directly powers your highest-consumption load rather than exporting cheaply to the grid.
Ducted A/C is typically the single largest load in a Western Sydney home, often drawing 4–8 kW when running continuously. Generic sizing calculators that rely on postcode averages routinely undersize systems for high-A/C households. EnerLogic pulls your actual half-hourly Ausgrid NMI data and identifies your summer consumption spikes by time of day — then sizes a system that captures those peaks rather than just covering baseload.
Yes — and the strategy for Western Sydney is slightly different to cooler areas. The key is pre-cooling: using solar to run the A/C hard between 10 am and 3 pm, dropping the house temperature before the Ausgrid peak period (4–9 pm weekdays, 50–57¢/kWh). The battery then covers evening loads without drawing expensive peak power. This combination — solar-powered pre-cooling plus battery discharge in the peak window — can reduce summer quarterly bills by $400–$700 compared with grid-only households.
Yes — Parramatta, Auburn, Granville, Merrylands, Guildford, Bankstown, Campsie, Canterbury, Lakemba and surrounding suburbs are all connected to the Ausgrid distribution network. This means you can access the NSW Battery Rebate ($2,400), Ausgrid's time-of-use tariff rates, and EnerLogic can retrieve your interval data directly from Ausgrid using your NMI number.
Your NMI (National Metering Identifier) is a 10-digit number on your electricity bill that uniquely identifies your connection to the Ausgrid network. EnerLogic requests your half-hourly interval data from Ausgrid using this number — giving us 12+ months of your actual consumption patterns at 30-minute resolution. For Western Sydney households with variable occupancy, large families and intensive summer A/C use, this real data is far more reliable than national averages for system sizing.
Western Sydney's high electricity consumption and strong solar irradiance typically produce payback periods of 4–6 years for a well-sized solar-only system, and 5–8 years when a battery is included (accounting for the $2,400 NSW Battery Rebate and STCs). The key word is 'well-sized' — a system undersized for your actual A/C load will under-deliver on savings, while an oversized system exports surplus at low feed-in rates. EnerLogic's NMI-based sizing eliminates both errors.
Builder-included solar packages are frequently undersized — typically 6.6 kW with a basic inverter — to keep the display price low. For a Western Sydney home with ducted A/C, a pool and a large family, 6.6 kW often covers less than 40% of actual consumption. EnerLogic can audit your existing system against your NMI interval data to show its actual performance, then advise whether adding panels (if inverter capacity allows), upgrading the inverter or adding a battery will deliver the best return.
