A 13kW solar system generates approximately 50 to 57 kWh of electricity per day on average across Australia, though actual output depends on your location, roof orientation, panel tilt, shading, and time of year. Properties in high-sunshine states like Queensland, Western Australia, and South Australia typically see output at the upper end of this range. Boost Solar provides a detailed, location-specific production estimate for your property during your free consultation so you have a clear and realistic picture of what your system will generate year-round.
Not at all — a 13kW system is an excellent fit for large homes with above-average energy consumption. It is particularly well-suited to households running electric vehicles, ducted multi-zone air conditioning, heated pools, electric hot water systems, and home offices all at the same time. It is also a forward-thinking choice for homeowners planning to add large battery storage or who anticipate their energy needs growing over time. Boost Solar will assess your current and future energy requirements to confirm whether a 13kW system is the right match for your property.
A 13kW system typically consists of 28 to 34 solar panels depending on the wattage of the individual panels selected. Using premium 400W panels requires approximately 33 panels, covering around 55 to 65 square metres of roof space. Boost Solar uses high-efficiency panels to maximise energy output while keeping the physical footprint as compact as possible. Our installation team conducts a thorough roof assessment to determine the optimal panel layout for your specific roof structure and orientation.
A 13kW solar system qualifies for the federal government’s Small-scale Renewable Energy Scheme (SRES), providing Small-scale Technology Certificates (STCs) that significantly reduce your upfront system cost. At 13kW, the STC rebate value is among the highest available for residential and small commercial installations — typically worth several thousand dollars depending on your location and current STC market pricing. For business owners, the ATO’s instant asset write-off may also allow the full system cost to be claimed as a tax deduction in the year of purchase. Boost Solar applies all eligible rebates directly to your quote and manages the entire claims process on your behalf.
The payback period for a 13kW system typically ranges between 3 and 6 years for most Australian homes and businesses, depending on your energy consumption patterns, the proportion of solar energy you self-consume versus export, your local electricity tariff, and your feed-in tariff rate. Properties and businesses with high daytime energy consumption tend to see the fastest payback due to maximised self-consumption of generated power. After the payback period, your 13kW system continues delivering clean, free energy and substantial savings for another 20 or more years — making it one of the most financially rewarding investments available to Australian property owners today.
