Six factors that move your real-world savings up or down from the headline estimate.
North-facing roofs at 20–30° produce the most energy in NSW.
Trees, chimneys and neighbouring buildings can cut output significantly.
Higher daytime usage means more solar self-consumed and bigger savings.
Higher export rates from your retailer increase savings on excess solar.
Stores daytime solar for evening use, lifting savings further.
Tier-1 panels and a quality inverter improve long-term yield and reliability.
We use a simple model based on your quarterly electricity bill and how much power you use during daytime hours, when solar panels generate the most energy. Households that use more electricity during the day get a bigger benefit from solar because more of the generated power offsets grid electricity directly.
For a fully accurate quote, a NSW-accredited solar installer needs to assess your roof orientation, available panel area, shading, switchboard, and which retailer plan and feed-in tariff suits your situation best. That's what we can arrange for you — at no cost and with no obligation.

Common questions from NSW homeowners about solar savings.
This calculator gives a general estimate based on your quarterly bill and daytime usage habits. It is a useful starting point, but a NSW-accredited installer needs to assess your roof, shading, switchboard and retailer plan for a precise quote. For real numbers, request a free solar quote.
Most NSW households cut their electricity bill by 50–80% with a properly sized solar system, and a few high-daytime-usage homes get close to zero. The exact figure depends on system size, daytime self-consumption, your feed-in tariff and retailer plan. Add a battery and you can push savings further — see are solar batteries worth it in NSW for the maths.
Yes. Modern solar panels still generate electricity on overcast days, typically at 10–25% of their full-sun output. Across a full year in NSW, cloudy days are already factored into the standard 5–6 kWh-per-kW-per-day generation estimate used by installers.
Yes. Most modern solar inverters are either battery-ready (DC-coupled) or can have a separate battery inverter added later (AC-coupled). If you plan to add a battery within a few years, tell your installer at quote time so they can size the system appropriately. Eligible systems may receive the federal Cheaper Home Batteries Program discount; a separate NSW VPP incentive may also apply to eligible batteries connected through a participating provider. See the battery incentive guide for details.
Eligible rooftop solar systems may receive a federal Small-scale Technology Certificate (STC) discount. Eligible home batteries may receive the separate federal Cheaper Home Batteries Program discount, and a qualifying NSW battery connected to a VPP may receive a separate NSW incentive. There is no general rebate for a private home EV charger; public and building grants are distinct. Retailer feed-in tariffs are not government rebates. See our solar rebates in NSW guide for more information.
