Quick Answer
Australia's major residential solar panels compared on wattage, module efficiency, product warranty and the typical installed price of a 6.6 kW system built with them. Sorted by system value per kW, cheapest first. Prices are post-STC-rebate as of August 2026.
| Solar panel | Watts | Efficiency | Product warranty | 6.6 kW system price | $/kW (6.6 kW sys) |
|---|---|---|---|---|---|
| Jinko Tiger Neo 475W | 475 W | 22.6% | 25 yrs | A$5,000–A$7,000 | A$909 |
| Trina Vertex S+ 450W | 450 W | 22.5% | 25 yrs | A$5,200–A$7,200 | A$939 |
| LONGi Hi-MO X10 470W | 470 W | 24.8% | 25 yrs | A$5,800–A$7,800 | A$1030 |
| Aiko Neostar 2S 470W | 470 W | 24.3% | 25 yrs | A$6,500–A$8,500 | A$1136 |
| Tindo Karra 440W | 440 W | 22.3% | 25 yrs | A$7,000–A$9,000 | A$1212 |
| REC Alpha Pure-RX 470W | 470 W | 22.6% | 25 yrs | A$7,500–A$9,500 | A$1288 |
System price = typical installed 6.6 kW system using that panel with a mid-range string inverter, after STC rebate. Methodology: median of real quotes plus published installer pricing.

Frequently asked questions
Which solar panel has the highest efficiency in Australia?
Back-contact panels from LONGi (Hi-MO X10, ~24.8%) and Aiko (Neostar, ~24.3%) currently lead. Mainstream N-type panels from Jinko and Trina sit around 22.5%.
Does panel efficiency actually matter?
Only when roof space is tight. Higher efficiency fits more kilowatts on the same roof; on a large unshaded roof, cheaper 22%-class panels usually deliver better payback.
Are these prices before or after the solar rebate?
After. Quoted system prices in Australia conventionally include the STC incentive, worth roughly A$1,800-2,500 on a 6.6 kW system in 2026.
