Solar Residential Panels Sydney
Solar Residential Panels Sydney: Price | STC | Battery Storage | ROI
Sydney has one of the highest rates of solar power installations worldwide. In fact, according to data from the Australian Photovoltaic Institute, more than 70% of the rooftops in several Sydney suburbs, including Schofields, have solar panel installations.
This article looks at the solar investment case and offers advice on how to choose solar panels in Sydney.
How much power do solar panels generate in Sydney ?
Sydney still has lots of solar hours, despite not being as sunny as Brisbane or Darwin. According to the PV Watts calculator from NREL, you should be able to produce an average of 3.96 kWh per day for every kWh installed in Sydney. This accounts for a 15% decrease in system efficiency, which is typical of Sydney solar systems of decent quality.
To make sense of this, we’ve put up the table of typical system sizes below. Kilowatt-hours (kWh), which appear on your electricity bill and are used by your electricity retailer to determine your quarterly or monthly electricity charges, are useful to keep in mind.

How much solar power can I get in daylight in Sydney.
- Any home with a moderately big, unshaded roof and some electricity usage during the day is a fantastic candidate for solar energy (see the sections below). This is so that you can save money in two different ways by using solar energy generated at home:
- Solar energy helps you use less energy from the grid or from your power retailer. You should do all in your power to maximise your self-consumption, which is also known as “solar self-consumption” and is the key to getting the most out of your solar system. Self-consumption in practise includes using your appliances (pool pump, washing machine, dish washer, etc.) throughout the daytime. Find out more about shiftable loads.
- Your system’s excess energy can result in credits on your electricity bill. This is typically referred to as a feed-in tariff for solar energy. Your home will automatically send any solar energy generated that is not immediately used back to the grid, giving you a feed-in credit. Feed-in tariffs were state-sponsored and rather generous a few years ago; today, they are slightly less generous but still sufficient to make solar energy an appealing investment.
- Your self-consumption and exportation rates together determine the worth of your solar energy. Your savings will be less than they would be if you were able to self-consume 40% or even, preferably, 60% of the energy generated by your 6.6kW of solar panels in Sydney, which generate an average of 26.1kWh/day.
- Therefore, it’s crucial that the system you select is suitable for your house and electrical needs. Based on how much energy you use and how it is used, we have created a tool to assist you in choosing the size of a solar PV system.
What rebates are available for solar panels Sydney
- Government STC Rebate for solar system in Sydney
- Sydney households who install solar can take advantage of the country’s small-scale technology certificate (STC) rebate under the Renewable Energy Target, just like everyone else in Australia. Simply put, the STC refund provides an upfront savings of about 30% for any solar installation in Australia with a capacity under 100kW.
- Depending on your location in Australia and the current market price for the certificates it generates, the reimbursement does vary slightly.The STC rebate is intended to be collected by the business that instals your solar system, and as a result, they will provide you with a net price after deducting the STC refund. In most quotes, the total costs (before the rebate) and the net cost to you are broken down (after the rebate).
- Interest-free loans for batteries from the NSW government
- The NSW government has established a programme to give customers who are installing batteries interest-free loans.
- Only residents in one of the postcodes listed on this page, which primarily cover the Hunter Valley and Blue Mountains regions, are eligible for the program.
- Further down this article, we provide some information on the financial benefits of solar batteries, but in Solar Choice’s opinion, an interest-free loan is insufficient to alter the economics of installing a battery.
How much do solar panels cost in Sydney?
- Australia has some of the lowest solar PV system pricing in the world, which is one of the reasons why so many houses and businesses have solar panels installed. This is in part due to the federal incentives mentioned above.
- Since 2012, Solar Choice has been monitoring developments in installation costs. As you can see in the table below, the cost of solar in Sydney nearly mirrors the national average.
- The graph below illustrates how costs for a variety of common system sizes have increased since 2012 (in terms of dollars per watt of capacity, or $/W). Our data from September 2022 shows that a typical 6kWsystem in Sydney costs about $5,420 on average after the STC rebate has been deducted.
What is the financial return for a solar panels Sydney customers?
- The quick response is yes, there is a significant return on investment for Sydney homes with the potential to save up to $2,707 annually on your energy bill and an usual payback period between 4 and 5 years. For a variety of scenarios, the table below displays payback times and yearly savings for a Sydney solar panel installation in the first year.
- Although we have made an effort to match system size to energy usage, the appropriate system size also relies on the time of day that energy is used in a residence. A reasonable amount of electricity is being consumed in the middle of the day, as indicated by the 40% self-consumption rate.

How about Sydney’s solar battery storage?
- In Sydney, solar batteries are substantially more expensive than solar panel installation. Despite the fact that battery functionality is well known and there are numerous manufacturers on the market, the return on investment is still subpar.
- Apparently, our expert, routinely evaluate the financial return of batteries and track the prices of solar batteries in the battery price index.The size of the solar and battery combination is adjusted to fit three basic use cases for solar batteries. See the Sydney solar and battery payback times and annual savings below.
