What Merrylands roofs are like

Merrylands is largely a large stock of 1960s and 70s brick homes with hip roofs facing several directions. A hip roof splits the array across faces, and how that is arranged decides whether the afternoon peak is covered.

That is why we do not quote a system size off a package name.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 we install in Merrylands

  • Solar panel installation

    Rooftop solar sized on your actual bills, installed by our own crew, with the price agreed in writing first.

  • Home battery storage

    Store what your roof makes during the day and use it at night, on a new system or fitted to the one you already have.

  • System design & sizing

    The part that decides whether your system was worth it, done on your usage and your roof before anything is ordered.

  • Inverter replacement

    The part that fails first, replaced without touching panels that are still doing their job.

  • Service & maintenance

    Checks, fault finding and repairs, including on systems we did not install and brands that have left the market.

  • EV charger installation

    A proper wall charger wired into your switchboard, set up to take what your roof is making rather than what the grid is selling.

What decides the job in Merrylands

  • A hip roof is a design decision

    Four faces means choosing which ones carry panels. North gives the biggest total, west gives you the afternoon, and which you want depends on when your household actually uses power.

  • West facing panels are underrated here

    If everyone gets home at five and the air conditioning goes on, a west split earns more than the raw kilowatt hour total suggests. It is worth modelling rather than defaulting to north.

  • Ducted cooling moves the sizing

    A lot of this stock has had ducted air added since. That is usually what takes a household from a 6.6kW system to a 10kW one.

Before you book

Solar in Merrylands, common questions

The ones that come up on nearly every first call, answered straight.

  1. Should my Merrylands panels face north or west?

    It depends on when you use power. North produces the most over a day; west produces later, which lines up with the evening peak and a hot afternoon. We model both against your usage rather than guessing.

  2. Does a hip roof cost more to install on?

    A little, because the array is split and each face needs its own run. It is a modest difference and it is on the quote. What matters more is getting the split right.

  3. Do you install in Merrylands?

    Yes. Merrylands 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.
