FAQs
Why should I choose your company for solar installation in Cowan?
We are a Clean Energy Council–accredited designer-installer with more than a decade of experience servicing the Cowan area. Our team specialises in integrating industry-leading panels (Tier-1 monocrystalline), high-efficiency micro-inverters, and smart energy-management software to maximise generation on Cowan’s bushland-shaded rooftops. From the initial site inspection through grid connection with Ausgrid, every stage is handled in-house, covered by a 10-year workmanship warranty, and supported by local technicians who can be on-site within 24 hours if you need assistance.
What sizes and types of solar systems do you install?
We design and install grid-connected, hybrid (battery-ready), and off-grid solar PV systems ranging from 3 kW residential packages to 100 kW commercial arrays. All systems use Tier-1 panels (440–550 W output) paired with either premium string inverters (Fronius, Sungrow) or Enphase IQ8 micro-inverters for complex, shaded roofs common in Cowan. For customers wanting energy independence, we integrate batteries such as Tesla Powerwall 2, BYD, or Sungrow SBR in scalable 5–30 kWh configurations.
How long does the solar installation process take?
A typical 6.6 kW residential system follows this timeline: 1. Obligation-free site assessment & quote – 1–2 days after your enquiry. 2. Network approval from Ausgrid – 3–7 business days. 3. Installation – usually completed in one day by our CEC-certified crew. 4. Electrical inspection & meter changeover – 2–10 business days, depending on your retailer. From signed quote to switch-on, most Cowan customers are producing solar power within 3–4 weeks.
What rebates or incentives can Cowan residents access?
All eligible installations receive Small-scale Technology Certificates (STCs), which reduce upfront costs by roughly $370–$400 per kilowatt installed. A standard 6.6 kW system attracts around 90 STCs, equating to a discount of $3,000–$3,600. In addition, you can export excess energy and earn feed-in tariffs (currently 7–15 c/kWh depending on retailer). If you install batteries, you may qualify for the NSW Empowering Homes low-interest loan program. We handle all paperwork so the rebate is applied as an instant discount on your invoice.
How much can I save on my power bills with solar?
Savings depend on your consumption patterns, system size, and tariff. A typical Cowan household using 25 kWh per day with a north-facing 6.6 kW system can expect to generate about 9,500 kWh per year. By self-consuming 60 % of that energy and exporting the rest at an average 10 c/kWh feed-in tariff, the first-year bill reduction is around $1,800–$2,100. With current electricity prices rising at ~4 % annually, most customers achieve a 3–4-year payback and 20+ % internal rate of return over the system’s 25-year lifespan.
Do you offer ongoing maintenance and system monitoring?
Yes. Every installation includes lifetime access to a cloud-based monitoring portal that displays real-time generation, consumption, and battery status on your phone or desktop. We proactively receive alerts for performance drops and can often resolve issues remotely. Optional maintenance packages include a biennial on-site inspection, panel clean, and electrical safety check. Even if you opt out, we recommend a system check every two years to keep your warranties valid and your array operating at peak efficiency.
