Reliable Solar Modules for Australia's Toughest Conditions

Our solar modules are designed to deliver uncompromising functional reliability even in the most challenging Australian environmental conditions.

Five Layers for Harvesting More Energy

Heterojunction solar cells use a three-layered structure to harvest more. One crystalline N-type silicon wafer surrounded by two thin amorphous silicon layers that we then protect with two layers of toughened glass.

This design boosts efficiency up to 22.53% by capturing at each layer. The top layer harvests bonus sunlight before it reaches the crystalline layer, and the lower layer absorbs any light that passes through.

Tougher Dual Glass Design

In Australia, solar panels often suffer from warranty problems caused by deteriorating plastic backsheets. To combat this, Dual Glass technology, which substitutes plastic with glass, has been developed, with Phono Solar leading its application in Australian homes.

This innovation is beneficial because it enables bifacial solar panels to harness power from both sides, potentially increasing energy yield by up to 25% under ideal conditions, marking a substantial leap in solar technology efficiency.
