Design solar and battery systems for New South Wales using Photonik's professional design platform. NSW dominated Australia's 2024 solar market with 97,475 installations, representing 31% of the national total. The state offers the Solar for Low-Income Households Program and competitive feed-in tariffs, making solar an attractive investment.

What drives your savings in New South Wales

New South Wales retail rates sit around 30–34c/kWh, making self-consumption the primary savings driver. Standard flat feed-in tariffs have fallen to 3–6c/kWh, but homeowners with batteries can access wholesale export pricing — earning 20–40c/kWh or more during peak demand periods (typically 4–8pm). This dramatically improves battery payback compared to fixed feed-in rates. Western and northern NSW enjoy strong solar irradiance above 5 kWh/m²/day, while Sydney and the coast are slightly lower but still generate well year-round.

Energy usage & tariffs

Energy consumption patterns in NSW reflect the state's diverse climate, from coastal regions to inland areas, with varying heating and cooling needs throughout the year. The average NSW household uses between 20-30 kWh per day, with Sydney properties typically at the lower end due to milder coastal climate, whilst inland areas may consume more for air conditioning during hot summers. Energy-efficient properties throughout NSW often use significantly less through modern insulation and efficient heating and cooling systems.

Before installing solar, consider reducing your energy consumption through improved insulation and energy-efficient appliances. This is particularly valuable in NSW, where the Solar for Low-Income Households Program can help eligible households access solar, and reducing consumption can lower the required system size and improve returns.

Estimated at 75% of the retail grid rate. A battery lets you store daytime solar and export during expensive peak hours, so each exported kWh is typically worth more than a flat feed-in tariff. Real returns depend on your time-of-use tariff and battery efficiency.

Solar system size

You'll need around 6.6kW of solar to match your average consumption in NSW. We recommend sizing between 9.9kW and 13.2kW for optimal results, accounting for daily and seasonal variations. NSW benefits from excellent solar potential, with Sydney and coastal regions averaging around 4.0-4.5 kWh/kW/day annually, whilst inland areas often achieve even higher generation rates.

A 9.9 kW system in NSW generates approximately 42.5 kWh daily on average, with seasonal variation from 3.41 kWh/kW/day in June to 4.82 kWh/kW/day in October. NSW's favourable solar conditions, combined with competitive installation costs, make solar particularly attractive for homeowners across the state.

A 8 kW system in New South Wales can generate approximately 12539.0 kWh annually based on local sun conditions.

Battery storage

With solar-only (no battery), a 9.9 kW system provides approximately 50% self-usage in NSW, depending on your consumption patterns, drawing 50% from the grid. Adding a 10 kWh battery increases energy independence to approximately 86% annually, reducing grid reliance to 14%. Battery storage is increasingly valuable in NSW, allowing you to store excess daytime generation for evening use and maximising the value of your solar investment as feed-in tariffs decline.

Standard flat-rate feed-in tariffs have fallen below retail rates in most states, but homeowners with batteries can now access wholesale export pricing through certain retailers and virtual power plant schemes. During peak demand periods (typically 4–8pm), wholesale rates can reach 20–40c/kWh or higher — fundamentally changing battery payback compared to a fixed feed-in tariff. For accurate battery savings and ROI calculations specific to your state and retailer, use the full Photonik design tool.
