How Many Solar Panels Do I Need?
If you’re thinking of investing in a solar system, you’re probably wondering how many panels you’ll need for your home. However, because every home’s usage and electricity needs are different, we’ve created this blog to act as a general guide only. For expert, individual recommendations of panel amounts and system sizes, simply request a callback with one of our expert energy consultants.
Please note all system sizes below are based on standard panel sizes of 265kW. However, Infinite Energy supplies panels as large as the SunPower 327W modules, which would reduce the number of panels required for the same-sized systems.
5 Solar Panels
5 panels will result in a system around 1.5kW in size. The average cost for a 1.5kW system from Infinite Energy using premium components is $2,490-$3,200, and will produce 7 units of electricity (kWh) per day. A 1.5kW system is perfect for households who receive an average electricity bill of $120 per cycle.
When operating at full capacity, a 1.5kW system can save you up to $105 per electricity bill.
6 Solar Panels
6 panels make up a solar PV system of approximately 2kW in size. Using the best components available, a 2kW system from Infinite Energy will cost between $2,690-$4,100, and produce 9 units of electricity (kWh) per day. A 2kW system is ideal for smaller households who receive an average electricity bill of $150 per cycle.
When fully utilised, a 2kW system can save you up to $90 to $145 per electricity bill.
10 Solar Panels
10 panels make up a solar PV system of roughly 3kW in size. Reliable and cost effective, a 3kW system from Infinite Energy will cost around $2,990-$5,600, depending on which components you choose. Producing 13 units of electricity (kWh) per day, a 3kW system is good choice for the average Australian household that receives an average electricity bill of $220 per cycle.
When used to maximum efficiency, a 3kW system can save you up to $120 to $200 per electricity bill.
13 Solar Panels
13 panels will result in a system around 4kW in size. Perfect for small to medium sized families, the average cost for an Infinite Energy 4kW system using the highest quality components is around $3,660-$6,900. Generating 18 units of electricity per day, a 4kW sized solar system is designed for those receiving electricity bills of around $300 per cycle.
When operating at full capacity, a 4kW system can save you as much as $270 per electricity bill. However, $140-220 is more common.
17 Solar Panels
17 panels make up a solar PV system of approximately 5kW in size, which is ideal for medium to large households using greater amounts of electricity. Using premium components, a 5kW system from Infinite Energy will cost between $3,790-$8,000, and produce 22 units of electricity (kWh) per day.
When fully utilised, a 5kW system can save you as much as $350 per electricity bill, although savings of around $180-300 are more common.
20 Solar Panels
20 panels will result in a system roughly 6kW in size. Perfect for medium to large sized families with a high electricity usage, a 6kW system is the maximum number of panels you can put on a 5kW inverter while claiming all of your Solar Tax Credits. The average cost for an Infinite Energy 6kW system using the highest quality components is around $3,990-$9,000. Generating 26 units of electricity per day, a 6kW sized solar system is designed for households that receive electricity bills of around $450 per cycle.
When operating at full capacity, a 6kW system can save you as much as $400 per electricity bill. However, $200-350 is more common.
23-27 Solar Panels
23-27 panels make up a solar PV system of around 7-8kW in size. Using the best components available, a 7-8kW system from Infinite Energy will cost between $7,170-$11,200, and produce 31-35 units of electricity (kWh) per day. A 7-8kW system is ideal for large households with an above average electricity consumption, who receive electricity bills of around $500 per cycle.
When fully utilised, a 7-8kW system can save you up to $300 to $505 per electricity bill.
30 Solar Panels
30 panels will result in a 9kW solar PV system. Perfect for large households with large electricity usage, the average cost for an Infinite Energy 9kW system using the highest quality components is around $9,600-$13,600. Generating 40 units of electricity per day, a 9kW sized solar system is designed for those receiving electricity bills of around $700 per cycle.
When operating at full capacity, a 9kW system can save you as much as $350-600 per electricity bill.
33 Solar Panels
33 panels make up a solar PV system approximately 10kW in size, the largest solar PV system available for residential use. Using the best components available, a 10kW system from Infinite Energy will cost between $9,900-$14,300, and produce 44 units of electricity (kWh) per day. A 10kW system is ideal for large households and home offices who receive electricity bills of around $800 per cycle.
When fully utilised, a 10kW system can save you up to $400 to $700 per electricity bill.
Your roof space is the biggest limitation of how many solar panels you’ll be able to install. If you can only fit 12 panels on your roof, you’ll only be able to install a system with 12 panels. If you are limited by roof space, you may wish to consider higher efficiency panels such as the Sunpower 327W as these give you more power for the same area.
