Low-Light Behavior

Sunrise, sunset and under cloud cover – CIS is better suited

Mornings, evenings, fog, diffused light, overcast skies – the sun isn’t always shining in full force. These conditions are one area where Solar Frontier’s CIS modules outperform competitors.

CIS modules effectively have access to longer “working hours”, enabling them to deliver more energy than crystalline silicon modules. More sensitive to lower intensities of light, they start generating electricity from earlier in the morning to later in the evening. CIS modules are also better at converting diffused light caused by cloudy conditions and moisture in the air.

These advantages enable Solar Frontier’s CIS modules to also generate more electricity in less than ideal conditions, such as when facing east, west and north, or when installed flat.
