Solar panel installation in Castle Hill
No two Castle Hill roofs are the same. Orientation, pitch and shade from trees or neighbouring homes all change how much power a system makes, so we start with a site inspection. We check your roof and switchboard, look at your power bills, and design a system around how and when your household uses electricity.
From established brick homes around Castle Towers to newer builds near Hills Showground station, many Castle Hill homes are larger, two-storey houses with plenty of roof space, which suits bigger systems that cover daytime use and charge a battery. We design for the roof you have, whether it’s tile, Colorbond or flat. Where the best roof faces east and west rather than north, we can split panels across both sides to spread generation through the day.
We only install Tier-1 panels from Jinko, Trina and Aiko, with inverters from GoodWe, Sungrow, Fronius and Sigenergy. If you’re thinking about a battery later, we’ll recommend a hybrid inverter that makes adding one straightforward. You can see more of our local work on our Hills District solar page.
Approvals and connection in Castle Hill
Castle Hill is on the Endeavour Energy network. Before we install, we apply to Endeavour Energy to connect your system, and after the install we complete the paperwork so your retailer can arrange your new meter. You don’t need to deal with the network yourself.
Most rooftop solar and battery systems on Castle Hill homes don’t need council approval from The Hills Shire. Heritage-listed homes and some heritage areas can be different, so we check this at the site inspection.
What affects the cost of solar in Castle Hill
Every quote is tailored to your home, but these are the main things that change the price:
- System size: worked out from your power bills and how much roof space you have
- Roof type and height: two-storey and steep roofs need extra safety equipment
- Switchboard: older switchboards sometimes need an upgrade before solar or a battery can be connected
- Battery: size, brand and whether you want blackout backup
- Rebates: STC solar rebates and the federal battery discount reduce the upfront cost

Home battery installation in Castle Hill
A battery lets you store the solar power you make during the day and use it at night. The federal Cheaper Home Batteries Program discounts eligible battery systems, and we’ll work out what it’s worth for your home and show it on your quote. The discount is set by the Clean Energy Regulator and was reduced in May 2026, so we calculate the current figure for your system and show it clearly on your quote. We install GoodWe, Sigenergy, Sungrow, Anker Solix and Tesla batteries. Learn more about batteries.

Castle Hill solar & battery FAQs
How long does installation take?
Most residential solar and battery installs are completed in one to two days, depending on system size and roof complexity.
Do I need a switchboard upgrade?
Not always. We check your switchboard at the site inspection and include any upgrade in your quote.
Can I add a battery later?
Yes. We’ll recommend an inverter that makes adding a battery down the track simple.
Do you install EV chargers?
Yes. We install home EV chargers in Castle Hill and check your switchboard and power supply first, so the charger suits your home and your car. If you have solar, we can set the charger up to use your spare solar power, where the charger supports it.
Will my home qualify for the federal battery discount?
Most homes do when the battery is an approved product installed by an accredited installer. The rules and discount amount are set by the Clean Energy Regulator, so we check your eligibility and show the current figure on your quote.
Do I need approval from Endeavour Energy or the council?
We handle the Endeavour Energy connection application for you. Most homes don’t need council approval, and we check at the site inspection if yours might.
What warranties do I get?
Every install comes with our 10-year workmanship warranty, on top of the manufacturer warranties on your panels, inverter and battery.
Do you install for Castle Hill businesses?
Yes. See our commercial solar page.
