In Dubbo (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 Dubbo — free and no obligation.
Dubbo enjoys an average of 4.8 peak sun hours per day, making it a fantastic location for solar. A 5kW system, with 13 modern 415W panels, will produce approximately 20.4 kWh per day. That adds up to 7,446 kWh per year. This output is based on standard orientation (north-facing at optimal tilt). To put that in perspective, the average Australian home uses around 15–20 kWh per day, so a 5kW system can cover a significant portion of your electricity needs.
For most Dubbo 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 Dubbo 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 Dubbo before deciding — bill savings depend on your tariff and usage shape, not averages.
A 5kW system is a perfect fit for medium-sized households in Dubbo where daytime electricity usage is moderate. If you have a family of 3–4, run appliances during the day, or work from home, a 5kW system can maximise self-consumption and reduce your grid reliance. It's also a great option if you plan to add a battery later, as it pairs well with common battery sizes. However, if you have high energy usage or pool pumps, you might consider a 6.6kW system.

Let's break down the savings for a 5kW system in Dubbo. With a daily output of 20.4 kWh, assume 40% self-consumption (2,978 kWh/year) and 60% exported to the grid (4,468 kWh/year). Using an electricity rate of 33c/kWh and an export FiT of 6.5c/kWh (typical for NSW), the annual benefit is: Self-consumption savings: 2,978 x $0.33 = $983. Grid export: 4,468 x $0.065 = $290. Total annual benefit: $1,273. The STC rebate for a 5kW system in NSW is approximately $243 (based on current STC price of ~$40 per certificate and zone rating). After rebate, the typical system cost is around $5,000–$6,000. So the payback period is roughly 5.5 years. Over 25 years, you could save over $30,000.
The Small-scale Technology Certificate (STC) scheme provides an upfront discount on solar installations. For a 5kW system in Dubbo (zone 3, which covers most of NSW), you'll create around 65 STCs (5kW x 13 years deeming period x zone rating of 1.0). At a market price of ~$37–$40 per STC, that's a rebate of about $2,400–$2,600. However, the exact amount depends on market conditions. Your installer typically assigns the STCs to themselves and deducts the value from your upfront cost. Note: The STC scheme is transitioning from January 2025, with new deeming rates reducing over time. Speak to a CEC-accredited installer for the latest rebate figures.
A 5kW system using modern 415W panels requires 13 panels. Each panel is roughly 1.7m x 1.1m, so total area is about 23 m². You'll need a clear north-facing roof section (or east/west if north isn't available) with no shading. The roof should be structurally sound and in good condition. Your installer will assess your roof during the site visit. If roof space is limited, consider higher-efficiency panels that produce more watts per square metre.
In NSW, the local distributor for Dubbo is Essential Energy. When installing a 5kW system, you need to apply for grid connection approval. Most residential systems under 10kW qualify for 'small generator' connection and don't require costly upgrades. The process is straightforward: your installer submits the paperwork on your behalf. After approval, you'll be able to export excess solar to the grid. Feed-in tariffs (FiTs) vary by retailer – typically 2–8c/kWh in NSW. Compare plans on Energy Made Easy to find the best FiT for your situation. There is no mandated minimum FiT in NSW, so shopping around is worthwhile.
