SunPower Solar Panels Review: The Differentiating Points

The following are the main reasons that distinguish SunPower solar panels as a preferred choice for solar panel installation:

IBC Solar Cell Technology

SunPower Maxeon Series solar panels feature interdigitated back contact (IBC) solar cells. IBC technology uses back-contact energy conversion as opposed to the more common front-contact conversion. Because the cells lack grid lines, they absorb more sunlight. The cells are supported by a tin-copper metal framework, which provides more corrosion resistance than the metal paste used in typical panels. The cells are connected by thick, triple-redundant connections, which control cell expansion and contraction according to temperature variations.


SunPower solar panels are designed to last for about 40 years.

More Power

In comparison to a typical solar panel, SunPower solar panels can provide 60% more output over a 25-year period.

Degradation Rate

Based on the panel type, their degradation rate is as low as 0.25%, which is exceptional given that most solar panels have a greater degradation rate.

Panel Efficiency

SunPower has the highest panel efficiency rating of 22.8%, making it the most efficient for residential solar panel installation in Sydney.


SunPower solar panels have a 25-year product and performance warranty.
