Solar Installer Hornsby: What Homeowners Should Know Before Going Solar
Solar Installer Hornsby: What Homeowners Should Know Before Going Solar
Considering solar in Hornsby? Here’s what to check before choosing an installer, from system sizing to compliance and battery placement.
Hornsby’s mix of established family homes, leafy blocks and a fair amount of tree cover makes solar a slightly different proposition here than in some flatter, newer-build suburbs. If you’re comparing installers for a solar or solar-and-battery system in Hornsby, here’s what actually matters beyond the headline price on a quote.
Why shading is the first thing to check in Hornsby
Hornsby and the surrounding area have more established tree canopy than many parts of Sydney, and that’s genuinely useful information for an installer to have before they quote your system. Shading from mature trees — yours or a neighbour’s — can significantly affect which parts of your roof are worth covering with panels, and at what time of day your system will actually generate. An installer should walk your roof (or at minimum assess it properly with satellite and shading tools) rather than quoting a standard package based on roof size alone.
What to check before signing a quote
System sizing based on your actual bills. Ask for the quote to be based on your last 12 months of electricity usage, not a generic package size. This is especially important in a suburb like Hornsby where shading can mean your effective generation differs from a simple roof-area calculation.
A proper shading assessment. Given the tree cover in the area, ask specifically how the installer has accounted for shading in their system design and panel layout — not just whether the roof “gets enough sun” in general terms.
Panel and inverter details, explained plainly. You should know exactly what panels and inverter are being quoted, their warranty terms, and why that combination was chosen for your roof.
Installer accreditation. Confirm the installer and business are Clean Energy Council (CEC) accredited, which affects your eligibility for Small-scale Technology Certificates (STCs) — the main source of upfront discount on a solar system.
What’s actually included in the price. Ask whether the quote covers any switchboard upgrade if required, scaffolding, tree trimming if shading needs managing, and the STC assignment paperwork. These are common places a low headline price turns into a higher final bill.
Battery-readiness. Even if you’re not adding a battery now, ask whether the inverter being quoted supports one later, so you’re not paying to replace equipment down the track.
Battery installation requirements in Hornsby homes
If you’re adding a battery alongside solar, the installation needs to meet AS/NZS 5139 requirements — clearances from doors, windows and combustible materials, plus ventilation. Hornsby’s blend of larger blocks, garages and established gardens means battery placement usually needs a proper site assessment rather than a generic recommendation, since where a battery can safely and practically go varies a lot from one property to the next.
