What Winston Hills roofs are like
Winston Hills is largely big 1970s brick homes with some of the largest unbroken roof planes in Western Sydney. This is the kind of roof where a 10kW system with a battery makes obvious sense.
That is why we do not quote a system size off a package name.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.

On these roofs
What decides the job in Winston Hills
Roof area is not the limit here
On most roofs the question is what will fit. On these it is what you actually need, which is a much better question to be answering.
Generation worth storing
A large north facing array produces more at midday than a household uses, and exported power earns a few cents. Holding it for the evening is where the money is on a roof this size.
One plane keeps the install simple
A single large face means one run, one orientation and a clean job, which is why these systems tend to price well per kilowatt.

Solar in Winston Hills, common questions
The ones that come up on nearly every first call, answered straight.

Should I fill the whole roof with panels?
Not automatically. Beyond what you use and what a battery can hold, extra panels only earn the export rate, which is a few cents. We size to your usage first and tell you what the extra rows are actually worth.
Is a battery worth it on a Winston Hills roof?
More often here than almost anywhere else we work, because the array can comfortably produce a surplus at midday. Whether it pays depends on how much you use after dark, which we read off your bill.
Do you install in Winston Hills?
Yes. Winston 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.
