FAQs
Is Cowan a good location for solar power, and how much sunshine can I expect?
Yes. Cowan sits on a ridgeline in northern Sydney’s Hornsby Shire and receives an average of 4.5–5.0 kWh of solar irradiation per square metre per day across the year—comparable with the broader Sydney basin. A well-oriented 6.6 kW system can therefore generate roughly 9,500–10,500 kWh a year, offsetting the bulk of an average household’s daytime demand.
Do I need council approval or any permits to install rooftop solar in Cowan?
Most residential systems up to 10 kW fall under ‘Exempt Development’ in NSW, so you generally don’t need a Development Application (DA) if panels are fitted flush to the roof and stay below the roof ridge line. However, you must lodge a connection application with Ausgrid so the system can be safely linked to the network. Our team handles this paperwork, including the technical data sheets, single-line diagrams and the ‘Permission to Connect’ request.
Are there rebates or incentives available for Cowan residents?
Two main incentives reduce the upfront cost: (1) Small-scale Technology Certificates (STCs), a federal rebate applied as an automatic discount when you purchase a compliant system—worth roughly $34–$38 per certificate in 2024, cutting a 6.6 kW system price by $2,400–$2,800; (2) Retailer feed-in tariffs, which pay you for exported energy (typically 5–15 c/kWh in NSW). While the NSW Government no longer offers a direct cash rebate, eligible households can still access the ‘Empowering Homes’ interest-free loan for solar-battery combos.
Can I export excess energy to the grid and what feed-in tariff will I receive?
Yes. Once Ausgrid approves your connection, your smart meter records any excess power you send to the network. Tariffs are set by individual electricity retailers—not the state—so they vary. At the time of writing, plans in the 2081 postcode offer rates between 5 c and 15 c per kWh. We help you compare retailers so you can choose one with a competitive feed-in rate and overall tariff structure that best suits your usage profile.
How do Cowan’s environmental conditions influence equipment selection and maintenance?
Cowan is a bush-adjacent village bordering Ku-ring-gai Chase National Park, so ember attack and higher leaf litter are considerations. We specify panels with anodised, corrosion-resistant frames, flame-retardant cabling (AS/NZS 5033 compliant) and elevated wiring to keep leaves clear. Annual cleaning is usually enough, but we recommend a professional inspection every two years—especially before summer—to check for debris, wildlife nesting and to verify the array’s earthing given the area’s occasional lightning activity.
What timeline and on-site process should I expect for a standard residential solar installation in Cowan?
1. Site inspection & quote acceptance: 1–3 days. 2. Grid-connection approval and ordering equipment: 5–10 business days. 3. Installation day: a 6 kW system typically takes one day; larger or multi-roof arrays may take two. 4. Electrical inspection & meter reconfiguration: 3–10 business days after install, depending on retailer. 5. System hand-over & monitoring set-up: immediately after meter change. End-to-end, most customers are generating solar power within 3–6 weeks of signing off the quote. During installation we isolate power temporarily (usually less than 30 minutes), follow WorkSafe roof-access protocols, and leave a hand-over pack containing compliance certificates, warranty documents and your monitoring app credentials.
