Features and Benefits

TNC N-Type Technology

Higher efficiency, stronger low-light performance, and superior temperature tolerance compared with traditional P-Type panels.

Bifacial Energy Gain

Captures reflected light from the rear surface for up to around 10% additional energy yield over the lifetime of the system.

Dual Glass Construction

Heat-strengthened glass front and rear delivers enhanced durability and moisture resistance – built to last in harsh conditions.

Hail & Salt Mist Tested

Tested with 45 mm hailstones at 110 km/h and certified to Level 8 salt-mist corrosion resistance for coastal sites.

Long-Term Warranties

25-year product warranty and 30-year linear performance warranty. 15-year product warranty applies to ground-mounted projects above 300 kW.

Built for Commerce

Tailored to the energy demands of Australian businesses – reliable output for warehouses, offices, schools, and commercial rooftops.
