In Gosford (NSW), shortlist CEC-accredited designers and installers who already work with Ausgrid, Endeavour Energy, or Essential Energy (by area). Every written quote should show: (1) STC pass-through for Zone 3 with the as-of date, (2) expected export limits on your street, (3) panel and inverter models from the CEC approved product lists, and (4) a workmanship warranty of at least five years on top of manufacturer warranties. Compare feed-in assumptions against local retailer offers around 2-8c/kWh, and treat optimistic bill-savings claims with caution unless self-consumption is modelled from your interval data. Most NSW councils treat compliant rooftop solar as exempt development under the State Environmental Planning Policy (Exempt and Complying Development Codes). Confirm heritage overlays and strata by-laws before install. Compare at least three quotes side by side before paying a deposit. MrSolar matches you with up to three CEC-accredited installers serving Gosford — free and no obligation.
A 10kW solar system in Gosford (4.8 peak sun hours) produces an average of 40.8 kWh per day. Over a month, that's approximately 1,224 kWh, and annually about 14,892 kWh. Generation varies seasonally: summer months yield more due to longer days and higher irradiance, while winter sees slightly lower output. This system is oversized relative to typical Gosford home consumption (around 15-25 kWh/day) so a significant portion will be exported to the grid, earning you a feed-in tariff. The table below summarizes daily, weekly, monthly, and annual production estimates.
For most Gosford households on 25–40c/kWh retail tariffs, a well-designed system pays back through self-consumed daytime energy first, then exports. A 6.6kW array around Gosford can generate roughly 33.0 kWh/day (12,045 kWh/year) at 5 peak sun hours — actual yield varies with roof pitch, shade, and inverter clipping. A typical 6.6kW system in STC Zone 3 currently points to about $1,435 in STCs (spot $39.85 as of 2026-08-05). Indicative 2026 metro pricing after STC for 6.6kW often lands near $5,000–$8,000; your roof and brand choice can move that band. If you have high daytime loads (WFH, pool, EV charging), solar is usually stronger than FiT-chasing alone. Get three CEC-accredited quotes for Gosford before deciding — bill savings depend on your tariff and usage shape, not averages.
A 10kW system is ideal for larger households (4+ people) with high daytime energy use, electric vehicles, pool pumps, air conditioning, or home-based businesses. If your annual consumption exceeds 7,000 kWh, this size can cover most or all of your needs. It's also suitable for properties with adequate roof space (around 43 m²) and good sun exposure. If you're unsure, speak to a CEC-accredited installer who can analyze your bills and recommend the best system size. MrSolar only works with vetted installers who provide quotes tailored to your home.
Assuming 40% self-consumption and 60% exported, with an electricity price of 33c/kWh and feed-in tariff of 6.5c/kWh, the annual savings are: Self-consumption: 5,957 kWh × 33c = $1,966. Grid export: 8,935 kWh × 6.5c = $581. Total annual benefit: $2,547. After the STC rebate (approx $486), the net cost of a typical 10kW system is around $6,000-$9,000, giving a payback period of about 2.7 years. Over a 25-year lifespan, total savings exceed $63,000. Actual savings depend on your self-consumption ratio, future electricity prices, and FiT rates.
The Small-scale Technology Certificate (STC) scheme provides a financial incentive for installing solar in Australia. For a 10kW system in Gosford (Zone 3), you are entitled to 126 STCs (based on deeming period of 10 years). At a market price of ~$3.86 per certificate, that's worth around $486. This rebate is typically assigned to the installer in exchange for an upfront discount, so you don't need to claim it yourself. Note that from 2025, the Renewable Energy Target is evolving, so stay informed via the Clean Energy Regulator. MrSolar ensures all installers factor in the correct STC value for your quote.
A 10kW system using modern 415W panels requires 25 panels. Each panel approximately 1.7 m x 1.1 m, so total roof space needed is about 43 m². For optimal performance, panels should face north with minimal shading. If roof space is limited, higher-efficiency panels (e.g., 430W+) can reduce the count to 23-24 panels. Installers will assess your roof during a site visit. CEC-accredited installers guarantee quality workmanship and compliance with Australian standards.
Gosford is in the Ausgrid network distribution area. Installing a 10kW solar system in NSW generally meets the requirements for standard connection (single-phase up to 10kW).

Feed-in tariffs (FiT) in NSW are not mandated; retailers offer rates from 2–8c/kWh. Use the Energy Made Easy website to compare plans. MrSolar strongly recommends checking with your retailer before installation to understand any network limitations.
