FAQs
Why is Cowan a good location for installing solar panels?
Cowan sits on Sydney’s Upper North Shore and enjoys an average solar irradiance of about 4.5–5.0 kWh/m² per day. That means roof-mounted panels can generate ample electricity year-round, even in winter. The area also has relatively mild temperatures, which helps solar modules operate more efficiently than in hotter inland regions. Combining strong sunlight with rising grid-power prices makes Cowan an ideal place to invest in solar.
How much can I expect to save on my power bills and what is the typical pay-back period?
For a standard 6.6 kW residential system in Cowan, annual generation is typically 9,500–10,500 kWh. If you self-consume 50 % and export the rest, most households cut their grid bills by $1,200–$1,800 a year (depending on retailer feed-in tariffs). With current system prices averaging $5,000–$7,000 after rebates, the simple pay-back period is roughly 3–5 years, after which the electricity your system produces is essentially free for the remainder of its 25-plus-year life.
What rebates or incentives are available for Cowan residents?
1. Federal STCs (Small-scale Technology Certificates) immediately reduce the upfront cost of any system under 100 kW; they typically slash 25–30 % off the invoice. 2. NSW Solar for Low Income Households provides free 3 kW systems to eligible concession-card holders. 3. The NSW Empowering Homes program offers interest-free loans (up to $14,000 for solar-battery combos) to owner-occupiers. 4. All exported energy earns a feed-in tariff from your electricity retailer (currently 6–15 ¢/kWh in most Cowan plans). We handle the paperwork for all of these incentives as part of our service.
What is the installation process and how long will it take?
Step 1: Site inspection and roof/ switchboard assessment (1–2 hours). Step 2: System design, quote approval and grid-connection application (2–5 business days). Step 3: Delivery and installation—most residential jobs take just one day; larger or multi-storey roofs may take two. Step 4: Electrical inspection and meter changeover (scheduled by your retailer/distributor within 2 weeks of installation). You can normally start producing solar power within 10–15 business days from signing the contract.
Do solar panels require much maintenance?
Solar PV systems are largely maintenance-free. Panel glass is self-cleaning with rain, but an annual hose-down or soft-brush clean improves output by 2–5 %. We recommend: • Visual inspection every 6–12 months for debris, shading from new tree growth, or cracked glass. • Inverter health check via its app or front display to confirm it is generating and logging data correctly. • Professional electrical safety test every 5 years. Our packages include the first annual clean and a 5-year workmanship warranty covering any mounting or cabling issues.
Should I add battery storage now or later?
Batteries add energy independence and blackout protection, but they also raise the upfront cost. In Cowan, a 10 kWh lithium battery can increase self-consumption to around 80–90 % and cut your bill to under $200 a year. Pay-back for batteries is typically 7–10 years, longer than for solar alone. Many customers start with a hybrid (battery-ready) inverter so a battery can be added later when prices fall or if their energy use rises (e.g., buying an EV). We will size your system and inverter to ensure a seamless future battery upgrade.
