Solar Panels Kellyville

Solar Sized for Kellyville Homes, Not Average Ones

The 2155 postcode installs more solar than almost anywhere else in NSW, and there is a simple reason for it. Kellyville homes are big. Four and five bedroom two-storey houses with ducted air conditioning, a pool pump running through summer, and increasingly an EV in the garage do not run on the 5kW system that suits an average Sydney home. They need 10kW, 13.2kW or more, usually on three-phase power, and ideally paired with a battery.

That is the kind of system we design every week across Kellyville, North Kellyville and Beaumont Hills. Our warehouse sits fifteen minutes away in Seven Hills, so site inspections book fast, stock is on hand, and the installer who quotes your job is the same local team that services it afterwards.

What Our Clients Have To Say!

New Builds in North Kellyville

If you are building or have just moved into North Kellyville, your home is likely battery-ready already: modern switchboard, three-phase supply, and conduit provisions. These are the fastest installs we do, often completed within a week of grid approval, and sizing the system correctly before your first summer in the house avoids a shock first-quarter bill. Endeavour Energy connection paperwork is lodged for you as part of the job.

How It Works

  1. Call 1300 179 949 or send the form with a recent bill.
  2. Site inspection covering roof, supply type, switchboard and, for retrofits, your existing system’s health.
  3. Fixed quote with STC and battery rebate paperwork prepared for you and discounts applied upfront.
  4. Installation, typically one day for solar, one to two for solar plus battery on a two-storey home.
  5. Handover and local support, with app setup, monitoring and a 10-year workmanship warranty backed by a team based fifteen minutes away.

What Makes Kellyville Different for Solar

Three-phase power is the norm, not the exception

Most homes built here from the late 1990s onward run three-phase supply. That opens up larger inverter capacity and better export limits, but it also means your installer needs to spec a three-phase inverter correctly. We confirm your supply type at inspection and design around it.

Two-storey installs need to be quoted honestly

A large share of Kellyville roofs are second-storey, which adds edge protection and access requirements. Some companies quote off satellite imagery and add these costs later. Every quote we issue follows a physical inspection and includes access costs upfront, so the number you sign is the number you pay.

Street appeal matters here.

All-black panels with concealed conduit runs are the most requested option in the Hills, and on the dark Colorbond and slate-look roofs common in North Kellyville they disappear into the roofline. If aesthetics matter to you, say so at the quote stage and we design for it.

High evening usage makes batteries the real story

Kellyville households are typically out during the day and running ducted aircon, cooking, washing and EV charging from 4pm onward, exactly when time-of-use tariffs peak at 30 to 45 cents per kWh. Solar alone exports your cheap daytime power for a 5 to 8 cent feed-in tariff and buys expensive power back at night. A battery fixes that mismatch, which is why most of our Kellyville quotes now include one.

Already Have Solar? Kellyville's Retrofit Wave

Thousands of Kellyville homes installed 5kW and 6.6kW systems between 2015 and 2019, back when feed-in tariffs made exporting worthwhile. Those tariffs are gone, but the panels still work, and in most cases the smarter move is adding a battery rather than replacing the system.

AC-coupled batteries like the SAJ and the Sigenergy SigenStor connect to your existing setup without touching your current inverter. We assess your existing system at inspection, tell you honestly whether it is worth keeping, and quote the retrofit with the federal battery rebate applied straight off the invoice, currently worth around $252 per usable kWh on the first 14kWh.

EV Owners: One System for the House and the Car

EV ownership in the Hills is climbing fast, and it changes the solar maths. Charging an EV from the grid at peak rates can add $1,000+ a year to your bills. Charging it from your own roof costs close to nothing.

For Kellyville EV households we design systems around that load, and for those who want the full setup, the SigenStor is currently the only residential battery in Australia with a built-in bi-directional DC charger, meaning your car can power your house during peak hours or a blackout. If you are choosing between battery brands, our home battery comparison covers the trade-offs.

What a Kellyville System Costs in 2026

Because homes here run bigger systems, budget guidance looks different to the Sydney average. A 10kW three-phase system typically lands between $8,000 and $11,000 installed after the federal STC incentive. A 13.2kW system with a 16 to 24kWh battery, sized for a large family home with an EV, typically runs $16,000 to $24,000 after both the solar incentive and the battery rebate.

Payback on solar plus battery in a high-usage Kellyville household typically runs 5 to 6 years, shorter than the Sydney average simply because the bills being replaced are larger. Bring a recent bill to the quote and we model your actual payback rather than a brochure figure.

Servicing Kellyville and the Surrounding Hills

Kellyville sits in the middle of our busiest service corridor. We install daily across North Kellyville, Beaumont Hills and Kellyville Ridge, where the newer housing stock makes for quick, clean installs. Rouse Hill and The Ponds to the north are part of the same run, along with Stanhope Gardens, Glenwood and Parklea on the western side.

Toward the established end of the Hills we cover Castle Hill, Glenhaven and Baulkham Hills, where larger blocks and older roofs call for a different system design, and the Norwest and Bella Vista business precinct for commercial work. Further west, Blacktown, Quakers Hill and Acacia Gardens are within twenty minutes of our base, and the growth estates around Marsden Park round out the corridor.

The full list is on our service areas page, or just call, anywhere in the Hills District is home ground.

Frequently Asked Questions

For a typical four-bedroom two-storey home with ducted aircon, 10kW is the realistic starting point and 13.2kW is common. Homes with a pool or an EV usually justify the larger size. We size from your actual bills at the quote stage rather than guessing.

Yes, for the better. Three-phase supply allows larger inverters and higher export limits, and it needs a three-phase inverter specified correctly. Most Kellyville homes built after the late 1990s are three-phase, and we confirm yours at inspection.

In most cases, yes, without replacing your existing inverter. AC-coupled batteries retrofit onto older systems, and the federal rebate applies. We check your existing system’s condition first and tell you straight if it is worth keeping.

Slightly, typically a few hundred dollars across a full system, and they are the most popular choice in Kellyville for good reason. On dark roofs the visual difference is significant. We quote both options if you are undecided.

Access and edge protection on a second-storey roof adds cost, and it should appear in your quote from day one, not as a variation later. Ours is included in the fixed price after inspection.

 Even for daytime households, yes in most cases now, because the rebate covers roughly 30% of the cost and blackout backup comes with it. For the typical Kellyville pattern of empty house by day and heavy usage from 4pm, a battery is usually the single biggest bill reducer available.
