Hi All,

Indeed, Delfi-C3 has quite high temperature extremes on the Cells. This data can also be viewed in the IV-curve display of RASCAL (it displays current temperature of the cell) The temperature is measured with thermistor strips.

However, we use space-grade cells which can handle the temperature.

Hi folks, Delfi - C3 uses partial deployed solar panels and whilst having  other on board problems is still sending data which I monitor on a regular basis. Remember also that it does not use batteries and is therefore only functional when in sunlight. Temperatures must be quite high on such a small area   - Just a  thought.
