10+ years ago I thought that Sunpower Solar wrote the best info. Their
module technology was superior and the classic 327 module output was
amazing in high temperature and also in cloudy skies. They were the
first to have really good warranty for both workmanship and output over
time.
I have
Good Morning;
Excellent update Rebekah (someone is up early). Module voltage stays pretty
linear as irradiance varies and temp stays constant. Currently the industry
calls this linear, but as the whitepaper Rebekah posted shows, it is not truly
linear.

Hi Jason,
That's an interesting question, as typically it is stated that temperature
coefficients are linear, however the "linearity" is with respect to the
temperature variable, not power (irradiance) I have always assumed that
tkPmp is fairly linear with respect to power, but now that you
I'm having a hard time finding concrete information on the relationship of
temperature coefficient and power output. Solar panel temperature
coefficients are determined at Pmax.
My question is, at lower irradiance levels, say where power output would be
50% of Pmax at 25C, would the temperature
