Solar Panels in Kellyville: What Local Homes Need
Most of Kellyville was built from the late 1990s to the 2010s, and the houses reflect that era: large double-storey homes, often with four or five bedrooms, a media room, ducted air-conditioning and a pool. Electricity use is high, especially across summer, and many households now also have an electric vehicle in the garage or on the way.
Many Kellyville homes already have a small solar system, often 1.5kW to 3kW, installed by the builder to meet BASIX energy requirements. Those systems are now ageing, the inverters are often near the end of their life, and they produce only a fraction of what the household uses. We can either expand the existing array or replace it with a properly sized system and battery, and we will tell you honestly which makes more sense for your roof.
Roofs here are usually concrete tile or Colorbond with good north and west faces. Some are steep and two-storey, so we include edge protection in every quote and plan cable routes so the inverter and battery sit neatly in the garage or on a side wall.
Solar & Battery Systems We Recommend for Kellyville Homes
For a typical five-bedroom Kellyville home with a pool and ducted air, our 15.2kW package with a 48kWh battery is the strongest fit. Households without a pool, or with a newer home that already meets high efficiency standards, often do well with the 13.3kW package and a 42kWh battery. We size for an EV charger if you plan to add one.
Getting more from solar in Kellyville
Kellyville homes are often the best candidates for whole-home electrification. With a large roof, a big battery and a modern switchboard, many households replace gas cooktops and hot water with induction and a heat pump, then run both largely on solar. We can plan the system with that in mind, even if you change appliances gradually. For EV owners, a smart charger can use only surplus solar during the day and draw from the battery or grid overnight only when needed. If your home has a three-phase supply, a three-phase hybrid inverter can make better use of a large array. And if the builder's original system is still under warranty, we can check its condition and tell you whether it is worth keeping as part of a larger upgrade.
Sizing a System for Your Kellyville Home
We start from your last four bills. In Kellyville that usually lands on the highlighted row, then the site visit confirms roof space and shading. If an EV, pool or heat-pump hot water is coming, say so now so the inverter is sized for it.

Endeavour Energy Connection in Kellyville
Kellyville is on the Endeavour Energy network. If you are replacing or expanding an older builder system, the whole installation is treated as a new connection application, and we handle that paperwork together with any meter changes.

Solar FAQs for Kellyville
How much do solar panels cost in Kellyville?
Packages start from $7,499 for 6.65kW solar with a 16kWh battery. The 15.2kW package we most often fit in Kellyville starts from $15,499. If you already have a small system, we quote both an expansion and a full replacement so you can compare.
How long does a solar installation take in Kellyville?
Network approval from Endeavour Energy usually takes a few days to two weeks, and the install itself is normally one day. Replacing an existing system adds a few hours for removal, but it is usually still done in a single visit.
Do I need council approval for solar panels in Kellyville?
Usually not. Rooftop solar on a house in The Hills is generally exempt development in NSW when standard conditions are met. If your estate has a community title or design guidelines, we check those before installation as well.
Do solar panels still work in Kellyville in winter?
Yes, at lower output on short or overcast days. We size Kellyville systems on your year-round usage rather than summer alone, and a battery evens out the difference by storing midday solar for the evening.
