Solar systems 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 39kWh of power a day or around 14,200kWh over 12 months.
The cost of solar panels 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.
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.
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.
For flat roofs, a slight tilt is recommended to avoid water pooling, while pitched roofs should follow the roof's angle. 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.
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.
