Solar panels in Sydney will naturally output more power in summer and less in winter.
As an example, a 5kW solar system in Sydney facing north with no shade will output an estimated 20kWh a day, averaged across the year, or around 7,100kWh over 12 months. Meanwhile, a 10kW solar system in Sydney will provide 40kWh of power a day or around 14,200kWh over 12 months.
The cost of solar system in Sydney depends on your system size, which will be determined by different factors such as your current energy bill and usage, as well as your roof size and budget. Good quality solar panels are now very much affordable, and it is possible to get a return on your money in 3-5 years.
Here's what determines the price of your solar system:
Solar Panels: High-quality solar panels last longer, provide more output, and are more reliable, though they are more expensive. We recommend reliable brands like 1KOMMA5° and Trina Solar. Avoid cheap Chinese panels due to their reduced quality and reliability.
Inverters: Inverters convert DC power from the panels to AC power for your home. Reliable brands like Enphase, Sungrow, and SolarEdge are recommended. High-quality inverters can last 15 years or longer, while cheaper ones may fail in a few years, leading to costly replacements.
Monitoring: Advanced monitoring options are available for detailed power usage and generation tracking.
As a guide, a fully installed 5kW solar system in Sydney costs from $5,000 to $8,000 and can save homeowners $1,800 a year. Meanwhile, a 10kW solar system in Sydney costs from $7,000 to $13,000 with annual savings estimated at $3,000.
Additional costs may be charged if you require installing split arrays, meter board work or high roof access.
In Sydney, the direction of your solar panels determine how much power your system can output. In general, solar panels generate the most energy when facing north, which is especially beneficial in winter. If a house has a north-south roofline, panels can be installed on the east or west side depending on the household's peak power usage times, often favoring the west for afternoon energy use.
For flat roofs, a slight tilt is recommended to avoid water pooling, while pitched roofs should follow the roof's angle. Solar panels facing north with a tilt of 30 degrees will generate the most output, although in winter this is closer to 25 degrees. The angle on which your panels sit has little impact on total yearly output but instead changes the times and seasons where your panels see ideal production. In short, tilting your solar panels in Sydney is mostly about matching the peak generation of the array with your lifestyle.
Splitting arrays using Enphase microinverters can optimize power output throughout the day, avoiding significant midday peaks. Strategic panel placement and consideration of time-of-use tariffs can greatly influence the system's efficiency and alignment with energy consumption patterns.
If you're just starting your solar journey, the first thing you need is to size up the right system for your needs and our team of experts can help you with this.
The right-sized solar system depends on what you want your system to do. For many people, it is about making sure the solar system pays for itself in as little time as possible. For others, it is to reduce their power bill by the greatest amount or to reduce their carbon footprint and do their bit for the environment.
Paying back your investment as quickly as possible requires sizing up a system to match your daytime energy usage. In a perfect situation, you would use all of the solar power that it generates and have the solar panels facing north or northwest to maximise your savings during the peak time of use billing period.
We offer some of the best solar panels available in Australia.
If you're looking for the best premium solar panel, we recommend the 1KOMMA5° full-black panels. It stands out for its premium performance, low carbon footprint, and ethical production, featuring German-made polysilicon and an all-black design.
It offers a 420W power rating, backed by a 25-year product and 30-year performance warranty. This panel is supported by one of the world's largest renewable energy companies and promises secure, long-term investment for customers.
If you're on a budget but still after a quality and reliable solar panel, you can choose the Trina Solar. Known as the best value panel, it's built to the highest quality standards, proving reliable in both field use and third-party testing, and excel in low light conditions for consistent high output.
The Trina Vertex S+ module is praised for setting a new standard in Australia due to its high performance and competitive pricing. Key features include double-glass construction and innovative cutting techniques for enhanced mechanical strength and reduced risk of damage.
These panels also guarantee a minimum of 87.5% power output after 30 years and boast a 22% module efficiency with advanced interconnect technology
Small-scale Technology Certificates (STCs) are a federal government incentive in which homeowners receive certificates for the solar energy their system will generate over a set period. These certificates can then be sold to help offset the upfront cost of installing solar panels. To find out if you qualify for this incentive, please contact our team.
The estimated lead time for a solar system with battery storage and/or an EV charger in Sydney is currently 2-4 weeks from the date of order confirmation. Once you place your order, our solar installation coordinator will reach out to you and schedule the installation time as soon as possible.
Many Australian households with solar installed are struggling to find aftermarket support after their original installer has gone bust. Since 2011 more than 750 solar installers have stopped trading, rendering their warranties useless. Look for a solar panel performance warranty of 25 years and a product warranty of 10-12 years and only purchase from a reputable installer.
First, ensure your plans for solar panel installation comply with all local council regulations. They will likely provide you with important permits and approvals to be completed prior to installation. Your solar installer will be able to assist in acquiring approval documentation. After installation, an inspector may look over your solar to ensure all components are performing correctly. Your solar retailer will then coordinate with your electricity provider to set up your meter and handle all necessary documentation.
Solar panels is an investment in your home, going for cheaper options may cause you significant issues in the long run and ultimately limit the financial benefits of installing solar power. With cheap solar systems you’ll often find the output isn’t what you were expecting or that components begin to break just as your system reaches its payback period. Installing cheap panels can leave you unable to make a warranty claim in the event of something going wrong due to liquidated or offshore manufacturers. More and more Australian solar systems are experiencing hotspots and browning significantly reducing their performance, not to mention the potential fire risk of cheap solar components.
There are three electricity retailers in NSW, which distributor your home falls under is dependent on your geographic region. The first is Endeavor Energy, serving southern and western metropolitan Sydney as well as the Blue Mountains and Illawarra regions. Followed by Essential Energy, who is responsible for country and regional NSW, and finally Ausgrid, servicing inner, northern and eastern metropolitan Sydney and surrounds. By looking on the Australian Energy Regulator website you can determine who your distributor is before your solar installation.
