LONGi's Hi-MO X10 panels bring back-contact efficiency (up to ~24.8%) to the volume market, undercutting Aiko while matching its headline numbers. A 6.6 kW LONGi system costs roughly A$5,800 to A$7,800 installed. The wafer giant's local support network is thinner than its manufacturing muscle.

Additional things to note about LONGi Solar?
LONGi's weakness in Australia is the gap between global scale and local presence: warranty claims route through a smaller support operation, and rapid product-line churn makes matching quotes to datasheets harder than it should be.

Are LONGi panels as good as Aiko?
On paper the Hi-MO X10 matches Aiko's back-contact efficiency at a slightly lower price. Aiko currently has the edge in Australian brand support and installer familiarity; LONGi wins on price.
