How much do LONGi solar panels cost in Australia?
LONGi solar panels cost $1000-$1500 per kW fully installed before rebates - around $6,600-$9,900 for a typical 6.6kW system. Federal STCs usually take $2,000-$3,500 off a 6.6kW system depending on your STC zone, so most households pay well below the sticker price.

How efficient are LONGi solar panels and how long do they last?
The LONGi Hi-MO 6 445W runs at 22.3% efficiency (HPBC Monocrystalline) and degrades just 0.4% per year, so it still produces strongly after 25 years. LONGi backs it with a 15-year product warranty and a 25-year performance warranty.
What solar rebates can I claim with LONGi?
Every LONGi system qualifies for federal Small-scale Technology Certificates (STCs), worth roughly $2,000-$3,500 on a 6.6kW system depending on your STC zone.
