What Baulkham Hills roofs are like
Baulkham Hills is largely large detached homes, many with ducted air conditioning. Ducted cooling is what moves a household from a 6.6kW system to a 10kW one.
That is why we do not quote a system size off a package name. We read twelve months of your usage, measure the useable roof rather than the total roof, and model the output face by face. You get the number and the assumptions behind it in writing.

What decides the job in Baulkham Hills
Ducted air is the sizing question
A ducted system running through a Western Sydney summer afternoon is the single biggest load on most of these houses, and it runs exactly when solar is producing.
Summer is the peak, not the average
Sizing off an annual average underestimates what a house like this needs in January. We look at the quarterly pattern rather than one number.
Pool and EV change it again
A pool pump can be shifted into daylight and cost you almost nothing. An EV charging at home is a second household's worth of power and needs planning for.

Solar in Baulkham Hills, common questions
The ones that come up on nearly every first call, answered straight.
Not on the list? Call 1300 958 778 or send it through.
How much solar do I need for ducted air conditioning?
More than the standard 6.6kW in most cases. Ducted cooling draws hard through the afternoon, which is good news because that is when panels produce. We size against your summer quarter rather than your annual average.
I am getting an electric car. Should I size for it now?
Yes, if it is coming within a year or two. Adding capacity at install is far cheaper than a second job later, and the sizing conversation is different once a car is in it.
Do you install in Baulkham Hills?
Yes. Baulkham Hills is inside our regular run across Parramatta and Western Sydney, and it is our own crew rather than a subcontractor. DSW Energy works under NSW electrical licence 497806C.
How much does it cost to install solar in Parramatta?
Our starting prices are $4,500 for a 6.6kW system and $8,500 for 10kW, for a standard single-storey install. What moves the number is the roof, not the postcode: two storeys, tile instead of sheet, a switchboard that needs upgrading, or an array split across several faces all add labour. We confirm the final figure in writing after a site assessment, so the price you accept is the price you pay.
Is there a solar rebate in NSW in 2026?
Not on panels, and that surprises people. There is no New South Wales rebate for rooftop solar. The discount you hear about is federal, it comes off the price as a point-of-sale deduction rather than a cheque you claim later, and every accredited installer in the state gets the same one. Batteries are different: a federal battery discount and a separate NSW incentive for connecting to a virtual power plant both apply, and they stack. We set out what you qualify for in writing with the quote, against the rules on the day.
What is the 33% rule for solar panels?
It is a rough guide that a solar system will typically cover around a third of a home's electricity use unless you change when you use power or add a battery. It is a reasonable sanity check on any sales pitch: if someone tells you panels alone will wipe out your whole bill, ask them to show you the numbers behind it. Shifting your washing, dishwasher and pool pump into daylight hours does more than most people expect, and a battery is what moves you past it properly.
Why do some people get rid of their solar panels?
Usually one of three reasons, and none of them is that solar stopped working. Systems installed a decade ago are reaching the end of their inverter life and get replaced rather than removed. Some were undersized for the household from the start and never delivered what was promised. And some were installed badly by companies that are no longer trading, which is the strongest argument for choosing an installer who will still be there in ten years. Panels themselves usually outlast everything else on the roof.
