Sydney solar panels and batteries

Sydney is one of the best locations in Australia to install a solar panel and battery system. With high electricity prices, a relatively mild climate and generous solar incentives available – the savings potential for solar and battery owners is very high.

Many Sydney-siders are already enjoying lower electricity bills due to solar. Over one in four households in Sydney already have solar panels. Since the introduction of the solar battery rebate in July 2025, some 88,118 ¹ batteries have been installed representing 4.58% of households in Greater Sydney.

For would-be owners, the solar landscape in Sydney can be complex: variable electricity rates, rebates, VPP providers, different micro-climates and the decisions to be made around home solar batteries. On this page we deliver the numbers that matter, cut through the complexity and help you to choose a top installer that will install good components that stand the test of time.

Solar power in Sydney

According to Clean Energy Regulator data, over 500,000 households in Greater Sydney have solar panels. The proportion of these systems that include a battery is just over 17% - many of which have been installed in the past 12 months.

Less solar systems have been installed in Sydney compared to the Greater Newcastle region, due to higher density housing like apartments and townhouses, where solar installation isn't as straighforward.

Sydney’s climate for solar

Sydney’s moderate climate is ideal for generating solar energy. A typical 8kW system can generate on average 32 kWh per day. The table shows the average solar output for different system sizes in Sydney:

Solar power output in Sydney

The Sydney region enjoys on average, 6.8 hours of sunshine each day. By comparison, Melbourne receives just 6 hours of sunlight. Sydney also enjoys a far milder winter which not only is better for generating more solar energy, it reduces the need for heating.

Sydney’s micro climates

Within Greater Sydney, exists different micro climates which impact energy use and solar generation. Using Bureau of Meteorology data, we can compare climate conditions in Penrith to the City Centre. The average temperature is 3°C warmer in Penrith compared to the City Centre as shown in the table below:

In summer, the temperature gap is 4.4°C, a huge differential. Not only do the warmer temperatures slightly reduce solar generation, but cooling energy requirements are higher.

Installation considerations in Sydney

There are local variants that will affect the output of your solar panels in Sydney:

• The panel angle
• The panel orientation
• Any shading on your solar panels

Panel angle

The best angle to install your panels in Sydney is 33.9°, which is the same angle as the latitude of the city. If you have a flat roof, you will need to mount the panels on an angle so that they clean themselves when it rains. Otherwise, a roof pitch either side of 33.9° will still generate a decent amount of solar energy.

Panel orientation

For all locations in Australia, including Sydney, it is best to orient your panels to the north. If you have an east/west roof orientation, your solar panels can still generate good output, particularly if your consumption habits align with the morning and late afternoon periods when your panels are generating power.

Shading of panels in Sydney

It is best to install your panels to avoid any shading issues. If it is not possible to do so, microinverters and power optimisers can mitigate the effect of shading on your panels, though both solutions add to the cost of your solar system.

Sydney solar and battery prices

Strong installer competition, high install volumes and consumer rebates, mean that solar panel prices in Sydney are as competitive as anywhere in the country. While adding a solar battery significantly increases the system cost, it will deliver far greater savings. We provide system prices for solar panels only and panel and battery systems below.

Average cost of solar panels in Sydney

Prices in Sydney are marginally cheaper than in Brisbane. While the table displays average prices, expect to pay more if you want the best solar panels.

Solar rebates available to Sydney residents

Sydney residents can take advantage of several solar and battery rebates, which can all be combined for greater savings. The table below outlines the three rebates available:

Rebate on solar panels

All New South Wales residents can get a solar rebate when they buy solar panels, providing the components are approved by the Clean Energy Council and the installation is carried out by a CEC accredited installer. The federal rebate can reduce the cost of your solar panels by as much as $1,360 for a 5kW system, or $1,800 for a 6.6kW unit.

Solar battery rebate

The national solar battery rebate is available to Sydney households and businesses. The battery rebate is worth approximately $252 per kWh of capacity installed - for the first 14kWh. Thereafter, the incentive reduces.

A 13.5 kWh battery in Sydney can deliver an upfront saving of approximately $3,367. Our solar battery rebate guide explains the ins-and-outs of the scheme including the key eligibility requirements.

NSW VPP incentive

The NSW VPP battery incentive is available to Sydney households, provided they have an eligible battery. The incentive is an upfront financial payment for participating in a Virtual Power Plant (VPP).

Data collated by the ACCC estimates that VPP participants can receive annual savings of between $184 - $433 more than solar and battery owners that choose not to join a VPP.

Solar payback and savings in Sydney

Solar panel systems typically payback between 4 - 7 years in Sydney. Adding a battery adds marginally to the payback time, but leads to far greater electricity bill savings. Our analysis below compares savings and payback results for both system types in Sydney. For results specific to your property, we recommend using our solar calculator.

Sydney solar panel system payback

For our analysis, we assume a four-person household in Sydney with an average quarterly bill of $755, that uses approximately 20 kWh per day of electricity. We have used an 8kW system for this analysis but the household may also consider a higher 10kW solar system.

The table highlights the sensitivity of the feed-in tariff price for solar panel systems. A 7c feed-in tariff sees the system payback in 4.8 years in Sydney, while an average 4c tariff increases the payback to 5.7 years.

The graphic below shows results for a 8kW system in Sydney:

Panel and battery payback in Sydney

The payback increases slightly to 6.2 years when a 13.8 kWh battery is added to the system as shown in the table below:

The lower feed-in tariff has less of an impact on savings with a panel and battery system.

Is adding a battery worth it in Sydney?

The payback and savings on both solar panel systems and, panel and battery systems, is favourable for most Sydney residents. There are two key reasons why installing a solar panel and battery system is likely to provide a better investment:

• Feed-in tariffs are trending down
• 3 Free hours of electricity

Feed-in tariffs are trending down

Feed-in tariffs, paid by electricity retailers for excess solar energy sent to the grid, are trending down. NSW feed-in tariffs typically range between 4c – 10c. As they get lower, the incentive to: self-consume solar power or, store it in a battery increases – therefore improving the financial case for adding a battery.

3 Free hours of electricity

Every Sydney household with a smart meter, can now receive 3 hours of free electricity each day through a participating energy retailer via the Solar Sharer scheme. The 3-hour free electricity window, effectively devalues solar panels – as this is when they produce most energy. It’s different for battery owners though, they can charge their battery during the free 3-hour period and use it later when electricity rates are expensive.

Sydney solar installers: How to find a good one

The quality of your system’s components and the installation work will determine how well your system performs and how long it lasts. We cannot stress enough the importance of the installation. This checklist highlights what to look for when buying solar panels from a Sydney installer company:
