Straight answers to common questions
Do you install solar panels across Sydney?
We install solar panels across Sydney's greater west: Penrith, Blacktown, Parramatta, the Hills District, Liverpool and Campbelltown, plus the suburbs around them. We deliberately keep our patch tight so we can quote fast, turn up on time, and come back quickly if you ever need us. Just outside those areas? Ask anyway, we take on nearby jobs when the schedule allows.
How much does a solar system cost?
Most homes we work on land somewhere between $4,000 and $12,000 installed, depending on system size, roof type and inverter choice, and after the federal rebate comes off. We quote a fixed price up front, so the number you see is the number you pay.
How long does installation take?
Most residential installs are done in a single day. Bigger systems, batteries or a switchboard upgrade can stretch it to two. We confirm the timeframe with your quote so there are no surprises.
Will solar actually cover my power bill?
It depends on your usage and when you use it. A well sized system typically cuts a power bill by 60 to 90 percent. We design from your real bills, not averages, and we will show you the expected numbers before you commit to anything.
Do you handle the rebate paperwork?
Yes, all of it. The federal STC rebate comes straight off your quoted price, and we lodge the grid connection application with your electricity network too. You do not need to fill in a single form.
What warranty do I get?
Panels typically carry a 25 year performance warranty and inverters 5 to 10 years from the manufacturer. On top of that, our workmanship warranty covers the installation itself, and because we are a local business, you can actually reach us if something needs attention.
Is my roof suitable for solar?
Most are. Tile, tin and Klip-Lok are all fine. Shading, roof age and orientation matter more than roof type, and we check all of that in a free assessment before we quote.
What size solar system should I get?
It comes down to your daily usage and when you use it. As a rough guide, a 6.6kW system suits most small to medium households, and 10kW or more suits bigger families, pools, ducted air con or an EV. We size from your actual bills, not a standard package. Our system size guide walks through the maths.
What do you need from me to prepare a quote?
Just your address and a recent power bill. The address lets us check your roof, shading and orientation on satellite, and the bill tells us how much power you actually use and what you pay for it. From those two things we can give you a fixed quote with realistic production and savings numbers.
