Thanks.   Just what I was looking for.

SolarPro magazine's module specifications tables. The excel versions are on our website under the Web extras" tab, which is found via the "magazine" pull down menu. We have temp coefficients for both Voc and Pmp. You can use the coefficient of Pmp in place of Vmp since temperature has little effect on current.

RE-Wrenches:

 

Does anyone know of a source that lists the temperature coefficient of Vmp for all commonly available modules?

 

My understanding is that, while this value is typically measured, it is not commonly published in module spec sheets.

 

It is useful when figuring the minimum number of modules in series.

 

Thank you for your assistance.
