What makes it different.
LONGi Hi-MO X10 Explorer uses HPBC 2.0 back-contact cells for a sleek front face, good shade tolerance and a low −0.26%/°C temperature coefficient for hot roofs. It reaches up to 24.0% efficiency.
How it works, simply: a panel's wattage is its output under standard test conditions, and efficiency is how much of the sunlight hitting it becomes electricity. Higher efficiency means more power from the same roof area.
It suits homes that want back-contact looks and performance at a mid-range price.
For Queensland conditions, the datasheet figures to note are a temperature coefficient of -0.26%/°C, which is how much output it loses for every degree the cells run above 25°C (Queensland roofs can run 30–40°C above that); a rated rear (wind uplift) load of 2400Pa; salt-mist corrosion certification (No data), relevant for coastal homes. Cyclone-region installs also depend on the mounting system and roof structure. We design to your wind region and AS/NZS 1170.2.
