Two Sydney quotes for “a 6.6kW system” can differ by thousands of dollars — and the cheaper one isn’t always the better buy. Comparing quotes properly shows you what you’re actually paying for, and which rebate assumptions sit behind each price.
A good quote separates hardware, installation, switchboard work and the STC discount. If it’s one lump figure, you can’t compare it fairly.
Panel tier, inverter brand and battery chemistry drive long-term value. Comparing named models — not “premium panels” — stops you being up-sold or short-changed.
Sizing, payback and battery value depend on how your household uses power. Comparing designs, not just prices, tells you which system genuinely suits you.
Our technical team designs home solar systems from 5kW to 20kW. Before we quote, we look at three things that decide whether a system will actually pay its way on your property.
North-facing roofs produce the most, but east–west splits suit households that use power in the morning and evening. We check tile, Colorbond and Klip-Lok roofs for fixing points, pitch and any repairs needed first.
Mature street trees in the Inner West and North Shore, or neighbouring two-storey homes, can cut output. We’ll recommend panel layout or optimisers where shading matters.
A recent bill tells us your daily kWh, tariff and when you use power. Pool pumps, ducted air-con or an EV in the garage all push the right system size up.

For bigger homes, acreage and businesses we also quote:
Spread the cost with a NSW green loan or solar battery finance, subject to lender approval.
In NSW, solar panels are supported by the federal STC scheme, and batteries by the federal Cheaper Home Batteries Program plus the NSW Peak Demand Reduction Scheme. These are point-of-sale discounts applied by your installer — not cheques you apply for.
Sydney is in STC Zone 3. In 2026, a 6.6kW system creates about 45 STCs — roughly $1,700 off at typical certificate prices. The deeming period falls from 5 to 4 years on 1 January 2027, so the same system earns fewer STCs next year.
Since 1 May 2026 the STC factor is 6.8 per usable kWh, tiered: full rate on the first 14kWh, 60% from 14–28kWh, 15% from 28–50kWh. It drops to 5.7 from January 2027. The aim is around 30% off a typical battery.
Connect an eligible battery to a VPP and you may receive an extra NSW incentive. From 1 July 2026, batteries up to 50kWh qualify, calculated on the first 28kWh. Value depends on battery size, location and certificate prices.
From 1 September 2026 the PDRS added new activities for apartment buildings and small, medium and large businesses. Commercial solar up to 100kW can still create STCs.

The installer matters as much as the panels. Use this checklist on any Sydney solar installer — including us.
Rebate-eligible systems must be designed and installed by Solar Accreditation Australia (SAA) accredited people, with a licensed electrician signing off.
Approved sellers under the New Energy Tech Consumer Code (NETCC) commit to fair sales practices, clear contracts and cooling-off rights. Clean Energy Council membership is another signal of industry commitment.
Ask who will actually be on your roof. In-house teams mean one point of accountability from quote to commissioning.
Panels, inverters and batteries should be on the approved products list, with model numbers in the quote — not just a brand.
Panel product and performance warranty, inverter/battery manufacturer warranty, and the installer’s own workmanship warranty — plus who services claims locally.
Years trading, recent local installs and independent reviews. Be wary of door-knockers and “today only” pricing.
STEP 1
Send the form, call 1300 131 989 or WhatsApp us. A recent power bill helps us size accurately.
STEP 2
Using satellite imagery and, where needed, a site inspection, we model roof layout, shading and output.
STEP 3
Named equipment, warranties, rebate discounts and inclusions — clearly laid out so you can compare.
STEP 4
Our in-house installers fit and commission the system, handle grid connection paperwork, and stay on call afterwards.
With feed-in tariffs well below what Sydney households pay for grid power, storing your daytime solar for the evening is where much of the saving now sits. We quote batteries for new solar systems and as add-ons to existing ones.
New systems usually pair with a hybrid inverter. Existing systems can often take an AC-coupled battery without replacing the inverter. We’ll check your current inverter, switchboard and space for wall- or floor-mounting.
Battery quotes depend on usable capacity (kWh), inverter power, backup capability and installation location. Rebates are strongest on the first 14kWh, so the best-value size is often smaller than people expect.

Lay your quotes side by side and check each of these. If a line is missing, ask for it in writing.
Brand, model and wattage; product warranty (years) and performance warranty — ours carry a 25-year linear output warranty.
String vs hybrid, kW rating, monitoring app and whether it’s battery-ready. We supply Fronius, Sungrow, GoodWe, FoxESS, Growatt, Solis and SolarEdge.
Panel, inverter and battery manufacturer warranties, plus the installer’s workmanship warranty. Ask who handles claims in Australia.
Double-storey or tilt frames, switchboard work, metering, grid-connection paperwork and removal of rubbish — included or extra?
Is the STC and battery discount already deducted, and at what certificate price? Any finance should show interest, fees and total repayable.
Who you call if output drops, how quickly they respond, and whether cleaning or maintenance is offered.
Call 1300 131 989 or message us on WhatsApp. Tell us your suburb, property type and whether you want solar, a battery or both — a recent electricity bill helps. We’ll review your roof using satellite imagery, ask a few questions about your usage, and send a free, itemised quote with no obligation to proceed.
Solar World’s systems currently start from $3,950 for 6.6kW, $5,400 for 10kW and $7,050 for 13.2kW. Your price depends on roof type, number of storeys, switchboard condition, inverter choice and whether a battery is included. Because STC discounts vary with system size and install date, always compare Sydney quotes on the net price after rebates.
Line up quotes for the same system size and check named panel and inverter models, all three warranties, what installation includes, and whether the STC discount is already deducted. Then compare the installer: SAA accreditation, consumer-code approval, in-house crews and genuine local reviews. The lowest headline price can cost more if extras are added later.
Many companies do, and it’s worth comparing a few. Solar World is based in Bankstown and our in-house team regularly installs across Western Sydney, including Parramatta, Blacktown, Fairfield, Penrith and Austral. Western Sydney’s larger roofs and long, hot summers make it one of the strongest regions for solar returns, especially when paired with a battery.
Yes. Parramatta and Blacktown are both well within our 50km service area, and we’ve completed residential and commercial solar, battery and EV charger installations in both. Send us your suburb or postcode and we’ll prepare a quote based on your roof, your usage and Endeavour Energy’s connection requirements.
Yes. We provide free solar and battery quotes throughout Penrith, Liverpool and the surrounding suburbs. Liverpool is one of our recent installation locations. Both areas have plenty of newer homes with good roof space, which often suits 10kW or larger systems — particularly for households running air-conditioning through Western Sydney summers.
Solar panels earn federal STCs, applied as an upfront discount — about 45 STCs for a 6.6kW Sydney system in 2026. Batteries can attract the federal Cheaper Home Batteries discount and, if connected to a Virtual Power Plant, the NSW Peak Demand Reduction Scheme incentive. Eligibility rules apply and amounts change, so your quote will show the exact figures.
We look at your evening usage, existing inverter and switchboard, and where the battery can be mounted. The quote then specifies battery brand, usable capacity, inverter, backup options, and the federal and NSW discounts that apply. Since rebates are tiered by size, we’ll show whether a smaller battery delivers better value for your household.
As a rough guide, 6.6kW suits average households, 10kW suits growing families or homes planning a battery, and 13.2kW or more suits high users with pools, ducted air-con or an EV. Roof space, orientation and your network’s export limit also matter. Your daily kWh from a recent bill is the best starting point for accurate sizing.
Inner West roofs are often smaller, split or shaded by trees and neighbouring buildings, so check how each installer has laid out panels and whether they’ve allowed for shading. Confirm heritage or council requirements for your street, ask about access for terraces, and compare expected annual output — not just system size — across your quotes.
Tree canopy is the big one — ask for a shading assessment and whether optimisers or micro-inverters are worthwhile. Check any heritage conservation area rules with your council, confirm roof condition on older homes, and make sure switchboard upgrades are priced in. Larger North Shore homes often benefit from pairing solar with a battery.
A clear system size, named panel and inverter models, a roof layout, estimated annual generation, all warranties, the STC discount, and a full list of inclusions and exclusions. It should also name the installing company and its accreditation. If anything is vague — “tier-one panels”, “standard install” — ask for it to be specified in writing.
Most residential rooftop systems are installed in a single day, with batteries sometimes adding a few hours. Lead time from quote acceptance depends on equipment availability and season — demand peaks before rebates step down. After installation, your electricity retailer and network arrange the meter changeover so you can start exporting to the grid.
Yes. We design commercial solar for Sydney businesses by first reviewing your electricity use and future plans, then recommending, installing and maintaining the right system. Systems up to 100kW can create STCs, and from September 2026 new NSW incentives apply to eligible business batteries. Call us and mention your business to start.
